Cervical cancer prevention and treatment research in Africa: a systematic review from a public health perspective

Outcomes of neoadjuvant chemotherapy and radical hysterectomy for locally advanced cervical cancer at Kigali University Teaching Hospital, Rwanda: a retrospective descriptive study

BACKGROUND

Half of countries in Africa lack access to radiation (RT), which is essential for standard treatment of locally advanced cervical cancers. We evaluated outcomes for patients treated with neoadjuvant chemotherapy (NACT) followed by radical hysterectomy in settings where no RT is available.

METHODS

We performed a retrospective descriptive study of all patients with FIGO stage IB2-IIA2 and some exceptional stage IIB cases who received NACT and surgery at Kigali University Teaching Hospital in Rwanda. Patients were treated with NACT consisting of carboplatin and paclitaxel once every 3 weeks for 3-4 cycles before radical hysterectomy. We calculated recurrence rates and overall survival (OS) rate was determined by Kaplan-Meier estimates.

RESULTS

Between May 2016 and October 2018, 57 patients underwent NACT and 43 (75.4%) were candidates for radical hysterectomy after clinical response assessment. Among the 43 patients who received NACT and surgery, the median age was 56 years, 14% were HIV positive, and FIGO stage distribution was: IB2 (32.6%), IIA1 (7.0%), IIA2 (51.2%) and IIB (9.3%). Thirty-nine (96%) patients received 3 cycles and 4 (4%) received 4 cycles of NACT. Thirty-eight (88.4%) patients underwent radical hysterectomy as planned and 5 (11.6%) had surgery aborted due to grossly metastatic disease. Two patients were lost to follow up after surgery and excluded from survival analysis. For the remaining 41 patients with median follow-up time of 34.4 months, 32 (78%) were alive with no evidence of recurrence, and 8 (20%) were alive with recurrence. One patient died of an unrelated cancer. The 3-year OS rate for the 41 patients who underwent NACT and surgery was 80.8% with a recurrence rate of 20%.

CONCLUSIONS

Neoadjuvant chemotherapy with radical hysterectomy is a feasible treatment option for locally advanced cervical cancer in settings with limited access to RT. With an increase in gynecologic oncologists skilled at radical surgery, this approach may be a more widely available alternative treatment option in countries without radiation facilities.

Drivers of cervical cancer prevention and management in sub-Saharan Africa: a qualitative synthesis of mixed studies

BACKGROUND

Cervical cancer is a public health concern in the sub-Saharan Africa region. Cervical cancer screening is one of the strategies for detecting early precancerous lesions. However, many women have poor access to and utilization of screening services in the region. This review aimed to synthesize evidence on the challenges and opportunities of screening, early detection and  management of cervical cancer in sub-Saharan Africa.

METHODS

We conducted a structured narrative review of studies published in English. We included studies published from 1 January 2013 to mid-2022. Studies were selected following Preferred Reporting Items for Systematic reviews and Meta-Analyses (PRISMA) guidelines. Key search terms (detractors and enablers, cervical cancer screening, sub-Saharan Africa) were employed to identify studies from three electronic databases (HINARI, Science Direct, and PubMed). We also conducted searches on Google Scholar to identify relevant grey literatures. A thematic analysis was conducted and themes were identified, then explained using a socio-ecological framework (intrapersonal, interpersonal, organizational, community, policy levels).

RESULTS

We identified 60 studies in the final review. Cervical cancer screening and early detection and management programmes are influenced by drivers at multiple levels. Individual-level drivers included a lack of knowledge about cervical cancer and screening literacy, and a low risk in perception, attitude, susceptibility and perceived fear of test results, as well as sociodemographic characteristics of women. Interpersonal drivers were community embarrassment, women's relationships with health workers, support and encouragement, the presence of peers or relatives to model preventive behaviour, and the mothers' networks with others. At the organizational level, influencing factors were related to providers (cervical cancer screening practice, training, providers' profession type, skill of counselling and sex, expert recommendation and work commitments). At the community level, drivers of cervical cancer screening included stigma, social-cultural norms, social networks and beliefs. System- and policy-level drivers were lack of nearby facilities and geographic remoteness, resource allocation and logistics management, cost of screening, promotion policy, ownership and management, lack of decentralized cancer policy and lack of friendly infrastructure.

CONCLUSIONS

There were several drivers in the implementation of cervical cancer screening programmes at multiple levels. Prevention and management of cervical cancer programmes requires multilevel strategies to be implemented  across the individual level (users), community and organizational levels (providers and community users), and system and policy levels. The design and implementation of policies and programmes need to address the multilevel challenges.

Attitudes of women towards screening, prevention and treatment of cervical cancer in Namibia

Background

Cervical cancer is among the top causes of cancer-related deaths among women globally.

Aim

The aim of the study was to assess the attitudes of women of reproductive age towards cervical cancer services in the Otjozondjupa region, Namibia.

Setting

The setting of this study was the Otjozondjupa region, one of the 14 regions of Namibia.

Methods

A quantitative, cross-sectional, descriptive study was used. The data were collected with a questionnaire from a stratified sample of 381 out of the 37066 study population of women of reproductive age across four districts of the region. Descriptive data analysis was performed using Statistical Package for Social Science version 25.

Results

The findings revealed that most respondents (83.1%) had an overall neutral attitude towards the screening, prevention, and treatment of cervical cancer; they were not concerned about the risk of cervical cancer and would not practice health-seeking behaviours regarding cervical cancer services.

Conclusions

The respondents were indifferent with regard to prevention, screening, and management services for cervical cancer, implying that they would not use available cervical cancer services.

Contributions

Attitudes of women of reproductive age towards cervical cancer services were highlighted. Subsequently, an educational programme for nurses to enhance the utilisation of cervical cancer services among women of reproductive age in the Otjozondjupa region, Namibia, was developed. Guidelines were developed to facilitate the implementation and evaluation of the educational programme activities to enhance the utilisation of cervical cancer screening services among women of reproductive age.

Willingness to take human papillomavirus vaccine and its associated factors among school adolescent girls: A case of school-based dose one human papillomavirus vaccine campaign in Dire Dawa, Ethiopia

Objective

This study aimed to evaluate the willingness of human papillomavirus vaccine and its associated factors in Dire Dawa in 2022. Ethiopia is undergoing human papillomavirus vaccine implementation in the country with the support of the Global Alliance for Vaccines and Immunization. However, there is a scarcity of data on problems encountered and the receiver's acceptance of the vaccine.

Methods

An institution-based cross-sectional study was conducted among 634 female adolescents from 1 April to 1 May 2022. A simple random sampling technique was used to select study participants. Pretested structured self-administered questionnaires were used to collect data. Data were entered into EPI-data 3.1 and exported to Statistical Package for the Social Sciences version 23.00 software for analysis. Descriptive analysis was conducted to summarize data with text, tables, and figures. A binary logistic regression model was fitted to identify factors associated with the willingness of the human papillomavirus vaccine. Adjusted odds ratios with 95% confidence intervals and p-values less than 0.05 were used to determine the association between independent and dependent variables. Hosmer and Lemeshow test was used to determine model fitness.

Results

The magnitude of human papillomavirus vaccine willingness among adolescent girls was 56% with 95% CI (52.1%-59.9%). Discussion on sexual and reproductive health issues (AOR = 7.67, 95% CI: 3.82, 15.42), adolescent girls who were received permission from their family to take human papillomavirus vaccine (AOR = 4.49, 95% CI: 2.40, 8.43), adolescent girls who had good knowledge on human papillomavirus vaccine (AOR = 5.78, 95% CI: 3.18, 10.15), and adolescent girls who had favorable attitude toward human papillomavirus vaccine (AOR = 3.06, 95% CI: 1.73, 5.43) were positively associated with willingness to take human papillomavirus vaccine.

Conclusion

Knowledge about cervical cancer and the human papillomavirus vaccine as well as willingness to take the human papillomavirus vaccine was low. Factors such as maternal education, adolescents' discussion on sexual and reproductive health issues, parent approval of human papillomavirus vaccine, and knowledge and attitude toward human papillomavirus vaccine were significantly associated with willingness to take the human papillomavirus vaccine. Therefore, public health education regarding cervical cancer and human papillomavirus vaccination is still needed and has to be targeted at not only respondents but also their families.

Autologous Tumor-Infiltrating Lymphocyte Mono-Therapy Can Rapidly Shrank Tumor in Asian Patient with Stage III/IV Cervical Cancer: Two Cases Report

Introduction

Tumor-infiltrating lymphocytes (TILs) therapy is one of the most promising adoptive T cell therapies, which has shown great clinical efficacy against several solid malignancies. Nevertheless, clinical response to TILs mono-therapy in Asian patients with recurrent cervical cancer has not been well reported.

Case Presentation

Here, we report two patients who were diagnosed with metastatic cervical cancer and tumor progression following multiple conventional treatments. In particular, one of the patients has a history of severe myelosuppression after chemotherapy. The patients received lymphodepletion therapy, which consisted of cyclophosphamide (30mg/kg) for 2 days, followed by Fludarabine (25mg/m2) for 5 days, approximately 24 hr before receiving intravenous autologous TILs infusion. These two patients then received high doses of IL-2 for 10 days with the purpose of maintaining T cell survival and proliferation. Patient 1 experienced clinical partial response (PR) at 6 weeks post TILs infusion and a 33% tumor shrinkage at 12 weeks follow-up, and patient 2 was evaluated as stable disease (SD) at 6 weeks post treatment. Mild and manageable adverse events were observed and soon subsided after the TILs treatment. A time-course study examining the peripheral blood cell count and cytokine secretion demonstrated the persistence of infused TILs and long-term immune response.

Conclusion

These results suggest that TILs mono-therapy can be a promising treatment strategy for Asian patients with late-stage metastatic cervical cancer even with severe myelosuppression. TILs infusion can induce persistence and a long-term systematic immune response that reversed peripheral CD4+T and CD8+T percentages implying that TILs infusion increased cytotic T cell responses, which is consistent with clinical responses in these patients. Trial registration number: NCT05366478.

Life-Threatening Endocrinological Immune-Related Adverse Events of Immune Checkpoint Inhibitor Therapy

Malignant neoplasms are currently one of the leading causes of morbidity and mortality worldwide, posing a major public health challenge. However, recent advances in research in cancer biology and immunity have led to the development of immunotherapy, which is now used on an everyday basis in cancer treatment in addition to surgical treatment, classical cytostatics, and radiotherapy. The efficacy of immunotherapy has promoted the great popularity of this treatment among patients, as well as significant research interest. The increasing number of patients being treated with immunotherapy not only reassures physicians of the efficacy of this technique but also shows the wide spectrum of side effects of this therapy, which has not been considered before. Immune-related adverse events may affect many systems and organs, such as digestive, cardiovascular, respiratory, skin, or endocrine organs. Most complications have a mild or moderate course, but there are life-threatening manifestations that are essential to be aware of because if they are not properly diagnosed and treated on time, they can have fatal consequences. The purpose of this paper was to present the results of a literature review on the current state of knowledge on life-threatening endocrine side effects (such as adrenal crisis, thyroid storm, myxoedema crisis, diabetic ketoacidosis, and severe hypocalcaemia) of immune checkpoint inhibitors to provide information on symptoms, diagnostics, and management strategies.

Improving Treatment Outcome for Cervical Cancer Using 2-Point Assessment of Quality of Life Among Nigerian Women: A Protocol for a Multi-Center Study

Background

Cervical cancer is the fourth most common cancer among women globally, with quality of life (QOL) being a major concern for patients with cervical cancer, especially in low- and middle-income countries (LMICs). This is largely due to the advanced nature of the disease at presentation. Although there are a higher number of studies focusing on the QOL of high-income countries, the QOL of cervical cancer patients in LMICs is not available. The aim of this study is to evaluate QOL among women with cervical cancer in Nigeria using a 2-point assessment.

Methods

A multi-center prospective cohort study will be conducted in 6 tertiary health facilities randomly selected from the 6 geopolitical zones of Nigeria and consisting of a 2-point assessment of the QOL of participants at the time of diagnosis of cervical cancer and after treatment. Women who were recently diagnosed with histologically confirmed cervical cancer (treatment naïve) will be included. QOL will be assessed using Quality of Life Questionnaire domains (EORTC QLQ30) as developed by the European Organization for Research and Treatment of Cancer (EORTC). In addition to the QOL assessment, relevant and clinicopathological variables will be obtained using a self-structured data extraction sheet designed for this study. All data will be anonymized and will be analyzed using SPSS version 25. Levels of QOL will be calculated using EORTC QLQ30. Ethical approval was obtained from National Health Research Ethics Committee (NHREC/01/01/2007-08/11/2021).

Discussion

In view of the paucity of data on QOL in LMICs like Nigeria, where most women with cervical cancer present with advanced disease, this research was designed to help in formulating evidence-based interventions to improve the QOL and treatment outcomes provided to women with cervical cancer in Nigeria and other LMICs. The study is expected to fill these knowledge gaps.

Cervical cancer prevention methods: awareness and use among urban Ghanaian women in Cape Coast, West Africa

Background

Cervical cancer is the fourth most frequent malignancy and common cause of mortality in women worldwide, despite being one of the most preventable female cancers.

Objectives

The aim of the study was to assess the awareness and knowledge of patients about cervical cancer prevention methods and the use of these methods by women in an urban setting.

Method

A cross-sectional study design was employed. A census was conducted to include all women (n = 153) who met the inclusion criteria and attended the gynaecology clinic of the Cape Coast Teaching Hospital from May to July 2022 for various gynaecological reasons. Data were collected using a structured questionnaire adapted from the Cervical Cancer Knowledge Prevention-64.

Results

The mean age was 40.0 years and ranges between 18 and 78 years. The majority of study participants had at least a secondary school level of education (78.8%), and almost all had at least a primary school education (95.4%). Most of the respondents (64.7%) were not aware of cervical cancer. Among those who had awareness, 64.8% of them knew about the existence of prevention methods; pap smear was the most common known method of prevention. There was a statistically significant association between the respondent's educational level and knowledge of the existence of cervical cancer prevention methods and the usage of pap smear. Only 16.3% of our study population has ever used a preventive method.

Conclusion

More than half of the participants were not aware of cervical cancer and its preventive methods, and those who were aware had insufficient knowledge, which translated to very low usage of cervical cancer preventive methods. There is an urgent need to intensify public education on cervical cancer.

Predictors of cervical tumour size for outpatients with cervical cancer at the University of Gondar referral hospital: a retrospective study design

BACKGROUND

Cervical cancer is one of the most serious threats to women's lives. Modelling the change in tumour size over time for outpatients with cervical cancer was the study's main goal.

METHODS

A hospital conducted a retrospective cohort study with outpatients who had cervical cancer. The information about the tumour size was taken from the patient's chart and all patient data records between May 20, 2017, and May 20, 2021. The data cover 322 cervical cancer outpatients' basic demographic and medical information. When analysing longitudinal data, the linear mixed effect model and the connection between tumour sizes in outpatients were taken into consideration. A linear mixed model, a random intercept model, and a slope model were used to fit the data.

RESULT

A sample of 322 cervical cancer outpatients was examined, and 148 (or 46% of the outpatients) tested positive for HIV. The linear mixed model with a first-order autoregressive covariance structure revealed that a change in time of one month led to a 0.009 cm2 reduction in tumour size. For every kilogramme more in weight, the tumour size change in cervical cancer patients decreased considerably by 0.0098 cm2. The tumour size change in the cervical cancer patient who was HIV-positive was 0.4360 cm squared greater than that in the HIV-negative outpatients.

CONCLUSION

As a consequence, there was a significant association between the longitudinal change in tumour size and the predictor variables visit time, therapy, patient weight, cancer stage, HIV, oral contraceptive use, history of abortion, and smoking status.

Health-related quality of life associated with different cervical cancer therapies received by patients in two Nigerian tertiary hospitals

Background

There are important consequences from cervical cancer (CC) disease and its treatment among survivors, especially the impact on quality of life (QoL).

Objective

To evaluate the health-related QoL associated with different CC therapies received by patients in two Nigerian tertiary hospitals.

Methods

This study employed a prospective longitudinal design. It was conducted at Usmanu Danfodiyo University Teaching Hospital, Sokoto and Ahmadu Bello University Teaching Hospital Zaria, North-Western Nigeria. Data of all the 157 eligible CC patients were collected at baseline and after therapy. Data analysis was done with appropriate descriptive and inferential statistics using SPSS V. 20 for windows. P<0.05 was considered statistically significant.

Results

Chemotherapy (CT) was the major therapy option received by 78(49.7%) of the patients. Patients who received chemoradiation therapy (CRT) and adjuvant chemotherapy (CTS) had the highest increase in mean overall health-related QoL of 0.138 (t=8.456, p<0.001) and 0.138 (t=6.489, p<0.001) higher than their respective baseline scores. Patients who received CT had the least increase in mean overall health-related QoL of 0.095 (t=4.574, p<0.001) from baseline.

Conclusion

Chemoradiation therapy and adjuvant chemotherapy were associated with highest increase in mean overall health-related QoL. Chemotherapy was associated with the least increase in mean overall health-related QoL.

Usage of cervical cancer screening services among HIV-positive women in Southern Ethiopia: a multicentre cross-sectional study

OBJECTIVES

To assess the usage of cervical cancer screening services and associated factors among HIV-positive women on antiretroviral treatment in Southern Ethiopia in 2020.

DESIGN

A multicentre cross-sectional study.

SETTING

The study was conducted in Wolaita Sodo University Teaching Referral Hospital and Sodo Health Centre, Southern Ethiopia, from 1 July 2020 to 30 September 2020.

PARTICIPANTS

Four hundred and seventeen HIV-positive women on antiretroviral treatment attending public health facilities were approached during the study period. A multivariable binary logistic regression model was carried out to identify independent factors associated with the usage of cervical cancer screening services, and a p value<0.05 was used to declare statistical significance.

RESULTS

The uptake of cervical cancer screening services among HIV-positive women was 27.8% with a 95% CI of 24.2% to 33.1%. Married women and women reporting a high level of perceived barriers were 75% and 66% less likely to receive cervical cancer screening services, adjusted OR (AOR)=0.25; 95% CI: 0.07 to 0.93, and AOR=0.34; 95% CI: 0.12 to 0.98, respectively. Whereas, being a government employee, AOR=3.85; 95% CI: 1.31 to 11.3, sexual debut before the age of 20, AOR=2.39; 95% CI: 1.09 to 5.26, using modern contraceptives, AOR=2.43; 95% CI: 1.05 to 5.65, having a high perceived self-efficacy, AOR=4.42; 95% CI: 1.79 to 10.89 and having a high perceived benefit of cervical cancer screening services, AOR=12.23; 95% CI: 2.22 to 67.35 were significantly associated with the usage of cervical cancer screening services.

CONCLUSIONS

The usage of cervical cancer screening services among HIV-positive women remains low in this setting. Married HIV-positive women and those with a high perceived barrier were associated with low uptake of cervical cancer screening services. Being a government employee, having an early sexual experience, using modern contraceptives, having a high perceived self-efficacy and having a high perceived benefit were identified as factors associated with increased uptake of cervical cancer screening services.

Female adolescents' knowledge and acceptability of human papillomavirus vaccine in Debre Tabor Town, Ethiopia: a cross-sectional study

OBJECTIVE

This study aimed to assess the knowledge and acceptability of the human papillomavirus (HPV) vaccine and associated factors among female adolescent students in Debre Tabor Town, Ethiopia, 2021.

DESIGN

Cross-sectional study was done from 9 December 2020 to 28 February 2021.

ANALYSIS

The data were entered into EpiData V.4.2 and analysed with SPSS V.23 software. The OR, 95% CI and p<0.05 were used to determine the bivariable and multivariable statistical association.

SETTING

Three high schools (grades 9 and 10) and six primary schools (grades 7 and 8) were included in the study.

PARTICIPANTS

Adolescent female students in Debre Tabor Town.

RESULTS

The overall knowledge score in the questionnaire was six, and it was divided into two groups based on scoring level: poor (score <3) and good (score ≥3). More than half respondents (59.2%) scored good knowledge. The proportion of acceptability of the HPV vaccine was 61.9%. Age (adjusted OR, AOR 1.70, 95% CI 1.17 to 3.88), and having a source of information (AOR 1.94, 95% CI 1.06 to 3.22) were significantly associated with the knowledge of the HPV vaccine. Place of birth (AOR 1.55, 95% CI 1.15 to 1.95), fathers' educational status (AOR 2.80, 95% CI 1.18 to 5.65), having a source of information (AOR 2.14, 95% CI 1.05 to 4.32) and knowledge about the HPV vaccine (AOR 6.41, 95% CI 3.45 to 11.90) were significantly associated with the acceptance of the female adolescent HPV vaccine.

CONCLUSION

In this study, the knowledge and acceptability of students of the HPV vaccine were low. Health authorities, through the mass media, should strengthen HPV vaccine promotion in schools, religious institutions and health facilities.

HPV genotypes in high-grade cervical lesions and invasive cervical carcinoma detected in Gabonese women

BACKGROUND

Cervical cancer is the third most common cancer among women worldwide, but particularly affects women living in sub-Saharan Africa. Screening and vaccination programs are two prevention approaches that can reduce cervical cancer incidence. However, effective vaccination campaigns require better knowledge of the prevalence of the main human papillomavirus (HPV) genotypes reported in high-grade neoplastic lesions and invasive carcinomas in women.

METHODS

All samples collected in this study were processed using standard histopathological methods with haematoxylin and eosin staining of the sections. Areas with abnormal cells were then identified. The HPV genotype was determined on the DNA extracted from the same sections using nested PCR followed by amplicon sequencing and real-time PCR specific to five different HPV genotypes (16, 18, 33, 45 and 58).

RESULTS

A total of 132 Gabonese patients with high-grade neoplastic lesions were included in this study; 81% were squamous cell carcinomas (SCC). At least one HPV was detected in 92.4% patients; HPV16 (75.4%) was the most frequent genotype, followed by HPV18, 58, 45, 33 and 35. Moreover, histological analysis showed that SCC samples had 50% and 58.2% stage III and IV tumor cells, respectively, according to the FIGO classification. Finally, 36.9% of these stage III and IV patients were less than 50 years old.

CONCLUSIONS

Our results confirm the high prevalence of HPV16 and 18 genotypes among high-grade lesions in Gabonese women. This study confirms the need for a national strategy for early screening of precancerous lesions associated with a broad national vaccination program among non-sexually active women to significantly reduce the long-term cancer burden.

The trend of change in cervical tumor size and time to death of hospitalized patients in northwestern Ethiopia during 2018-2022: Retrospective study design

Background and Aims

Cervical cancer is the fourth most common cause of cancer-related death in the world. The objective of this study was to determine factors that affect the longitudinal change of tumor size and the time to death of outpat.

Methods

A retrospective follow-up study was carried out among 322 randomly selected patients with cervical cancer at the University of Gondar Referral Hospital from May 15, 2018 to May 15, 2022. Data were extracted from the patient's chart from all patients' data records. Kaplan-Meier estimator, log-rank test, the Cox proportional-hazard model, and the joint model for the two response variables simultaneously were used.

Results

Among 322 outpatients with cervical cancer, 148 (46%) of them were human immunodeficiency virus (HIV) positive and 107 (33.3%) of them died. The results of joint and separate models show that there is an association between survival and the longitudinal data in the analysis; it indicates that there is a dependency between longitudinal terms of cervical tumor size and time-to-death events. A unit centimeter square rise in tumor size, corresponding to an exp(0.8502) = 2.34 times, significantly raised the mortality risk.

Conclusion

The study showed that HIV, stage of cancer, treatment, weight, history of abortion, oral contraceptive use, smoking status, and visit time were statistically significant factors for the two outcomes jointly.

Implications

As a result, adequate health services and adequate resource allocations are critical for cervical cancer control and prevention programs. Therefore, the government should provide adequate funding and well-trained health professionals to hospitals to sustain screening programs with appropriate coverage of cervical cancer patient treatments.

Cervical Cancer Screening Service Utilization and Associated Factors Among Women Living With HIV Receiving Anti-Retroviral Therapy at Adama Hospital Medical College, Ethiopia

Introduction

Cervical cancer is the second highest cause of cancer-related mortality in the world, and it is one of the top 20 causes of mortality in Ethiopia. Even though cervical cancer is more common among women living with HIV, the utilization of cervical cancer screening services remains low in Ethiopia.

Objectives

This study aimed to assess cervical cancer screening service utilization and associated factors among women living with HIV receiving anti-retroviral therapy at Adama Hospital Medical College, Ethiopia.

Methods

An institution-based cross-sectional study was conducted among a sample of 304 women living with HIV from 1st-30th June 2022. Data were collected using an interviewer-administered questionnaire. The data were entered into Epi info version 7 and exported to SPSS version 25 for analysis. Bi-variable logistic regression analysis was used to identify candidate variables at p < .25. Finally, multivariable logistic regression analysis was used to identify the independent predictors of cervical cancer screening service utilization at p < .05 with 95% confidence intervals.

Results

The magnitude of cervical cancer screening service utilization was 26.9% (95% CI: 22.0, 32.6). Being a government employee (AOR: 8.09, 95% CI: 1.5, 41.19), having a family history of cervical cancer (AOR: 3.4, 95% CI: 1.02, 11.9), being aware of cervical cancer screening (AOR: 3.75, 95% CI: 2.11, 14.7), having a history of sexually transmitted infection (AOR: 3.14, 95% CI: 1.95, 10.2), and heard about cervical cancer (AOR: 2.6, 95% CI: 1.05, 6.41) were associated with cervical cancer screening service utilization.

Conclusion

The magnitude of cervical cancer screening service utilization was low. It was associated with occupation status, family history of cervical cancer, awareness about cervical cancer screening, history of STI, and ever heard about cervical cancer. Thus, to maximize utilization, health education programs and other multidisciplinary strategies had to be implemented.

Screening for cervical cancer among women in five countries in sub-saharan Africa: analysis of the role played by distance to health facility and socio-demographic factors

BACKGROUND

Cervical cancer significantly affects women in Sub-Saharan Africa (SSA). However, limited studies have concentrated on cervical screening behaviour among women in SSA. This study aimed to assess the interplay of distance to health facilities and socio-demographic factors with cervical screening behaviour among women in five SSA countries.

METHODS

The study was based on pooled data of 40,555 women included in Demographic and Health Surveys (DHS) conducted between 2013 to 2021. Proportions and logistic regression models were used in assessing the interplay of distance to health facilities and socio-demographic factors with cervical screening behaviour.

RESULTS

Approximately, 7.9% of women that saw the distance to a health facility as a big problem, tested for cervical cancer compared to 13.5% who indicated that distance to a health facility is not a big problem. More women in urban areas, with a higher level of education, of richest wealth index, aged 40-44 years and using contraceptives who also indicated that distance to a health facility was a big problem tested for cervical cancer compared to those in rural areas with no education, of poorest wealth index, aged 15-19 years and not using contraceptives. Education, age, contraceptive use, frequent exposure to mass media and Sexual Transmitted Infections (STI) had a significant relationship with testing for cervical cancer.

CONCLUSION

The prevalence of cervical cancer screening was low in the five SSA countries largely due to distance barriers and was also significantly influenced by education, age, contraceptive use, frequent exposure to mass media, and STI status. To improve the screening for cervical cancer and its associated benefits in the five SSA countries, there is a need for policymakers, clinicians and public health workers to channel more commitment and efforts to addressing the barriers identified in this study.

Usefulness of high-risk HPV early oncoprotein (E6 and E7) serological markers in the detection of cervical cancer: A systematic review and meta-analysis

We reviewed the literature on the importance of selected anti-high-risk human papillomavirus (HR-HPV) antibodies (namely, 16/18 and early oncoproteins E6 and E7) as potential serological markers for early detection of individuals at high risk of cervical cancer. We searched for studies in PubMed and Embase databases published from 2010 to 2020 on antibodies against HR-HPV E6 and E7 early proteins and cervical cancer. Pooled sensitivity and specificity for HPV16 and HPV18 antibodies were calculated using a bivariate hierarchical random-effects model. A total of 69 articles were identified; we included three studies with 1550 participants. For the three HPV16/18 E6 and E7 antibody tests, enzyme-linked immunosorbent assay-based assays had a sensitivity of 18% for detecting CIN2+ (95% confidence interval [CI]: 15-21) and a specificity of 96% (95% CI: 92-98), for slot-blot, sensitivity was 28.9% (95% CI: 23.3-35.1) and specificity was 72% (95% CI: 66.6-77.0) for detecting CIN2+, and for multiplex HPV serology assay based on a glutathione S-transferase, sensitivity was 16% (95% CI: 8.45-28.6) and specificity was 98% (95% CI: 97-99) for detecting invasive cervical cancer. HR-HPV16/18 E6 and E7 serological markers showed high specificity, but sensitivity was suboptimal for the detection of cervical cancer in either population screening settings or as point-of-care screening tests.

4-O-Methylascochlorin-Mediated BNIP-3 Expression Controls the Balance of Apoptosis and Autophagy in Cervical Carcinoma Cells

4-O-methylascochlorin (MAC) is a 4-fourth carbon-substituted derivative of ascochlorin, a compound extracted from a phytopathogenic fungus Ascochyta viciae. MAC induces apoptosis and autophagy in various cancer cells, but the effects of MAC on apoptosis and autophagy in cervical cancer cells, as well as how the interaction between apoptosis and autophagy mediates the cellular anticancer effects are not known. Here, we investigated that MAC induced apoptotic cell death of cervical cancer cells without regulating the cell cycle and promoted autophagy by inhibiting the phosphorylation of serine-threonine kinase B (Akt), mammalian target of rapamycin (mTOR), and 70-kDa ribosomal protein S6 kinase (p70S6K). Additional investigations suggested that Bcl-2/adenovirus E1B 19 kDa protein-interacting protein 3 (BNIP-3), but not Hypoxia-inducible factor 1 alpha (HIF-1α), is a key regulator of MAC-induced apoptosis and autophagy. BNIP-3 siRNA suppressed MAC-induced increases in cleaved- poly (ADP-ribose) polymerase (PARP) and LC3II expression. The pan-caspase inhibitor Z-VAD-FMK suppressed MAC-induced cell death and enhanced MAC-induced autophagy. The autophagy inhibitor chloroquine (CQ) enhanced MAC-mediated cell death by increasing BNIP-3 expression. These results indicate that MAC induces apoptosis to promote cell death and stimulates autophagy to promote cell survival by increasing BNIP-3 expression. This study also showed that co-treatment of cells with MAC and CQ further enhanced the death of cervical cancer cells.

Cervical cancer in sub-Saharan Africa: an urgent call for improving accessibility and use of preventive services

Sub-Saharan Africa has the highest rates of cervical cancer in the world, largely attributed to low cervical cancer screening coverage. Cervical cancer is the most common cause of death among women in 21 of the 48 countries in sub-Saharan Africa. Close to 100% of all cases of cervical cancer are attributable to Human papillomavirus (HPV). HPV types 16 and 18 cause at least 70% of all cervical cancers globally, while types 31, 33, 45, 52, and 58 cause a further 20% of the cases. Women living with HIV are six times more likely to develop cervical cancer than those without HIV. Considering that sub-Saharan Africa carries the greatest burden of cervical cancer, ways to increase accessibility and use of preventive services are urgently required. With this review, we discuss the preventive measures required to reduce the burden of cervical cancer in sub-Saharan Africa, the challenges to improving accessibility and use of the preventive services, and the recommendations to address these challenges.

A Qualitative Exploration of Barriers to Treatment Among HPV-Positive Women in a Cervical Cancer Screening Study in Western Kenya

BACKGROUND

Cervical cancer screening through self-collected high-risk human papillomavirus (HPV) testing has increased screening uptake, particularly in low-resource settings. Improvement ultimately depends, however, on women with positive results accessing follow-up treatment. Identifying the barriers to timely treatment is needed to tailor service delivery for maximum impact.

MATERIALS AND METHODS

This qualitative study was conducted within a self-collected HPV screening trial in Migori County, Kenya. HPV-positive women were referred for no-cost cryotherapy treatment at the county hospital. Women not attending within 60 days of receiving HPV-positive results were randomly selected for in-depth interviews (IDIs). IDIs were coded and analyzed to develop an analytical framework and identify treatment barriers.

RESULTS

Eighty-one women were interviewed. IDIs showed a poor understanding of HPV and cervical cancer, impacting comprehension of screening results and treatment instructions. All 81 had not undergone treatment but reported intending to in the future. Eight reported seeking treatment unsuccessfully or not qualifying, primarily due to pregnancy. Transportation costs and long distances to the hospital were the most reported barriers to treatment. Other obstacles included work, household obligations, and fear of treatment. Impacts of social influences were mixed; some women reported their husbands prevented seeking treatment, others reported their husbands provided financial or emotional support. Few women experienced peer support.

CONCLUSIONS

Women faced many barriers to treatment following HPV screening in rural Kenya. Transportation barriers highlight a need for local treatment capacity or screen-and-treat approaches. Ensuring women understand their results and how to seek treatment is essential to improving cervical cancer screening in low-resource settings.

A Comparative Analysis of Visual Inspection With Acetic Acid, Cervical Cytology, and Histopathology in the Screening and Early Detection of Premalignant and Malignant Lesions of the Cervix

Introduction: The incidence of cervical cancer and related mortality is growing worldwide. The natural history of disease progression ranges from 10 to 20 years. Hence, effective screening can help in the early detection and prevention of fatal complications. This study aims to (1) compare the sociodemographic characteristics of the women with malignant and premalignant lesions of the cervix, (2) collate the accuracy of visual inspection of the cervix with acetic acid (VIA) with Pap smear cervical cytology in the early detection of premalignant and malignant lesions of the cervix, and (3) standardize it with histopathology, a gold standard screening tool.

Methods: This study was carried out in the Department of Obstetrics and Gynaecology, Gajra Raja Medical College, Gwalior, India, from October 2020 to March 2021 including all the sexually active women of the reproductive age group and postmenopausal women attending the gynecology outpatient department and the indoor admitted patients. A total of 500 patients were included in the study. The women were subjected to a Pap smear followed by VIA. Punch biopsy was taken from the acetowhite regions and sent for histopathological examination. The women with abnormal cervical cytology results also underwent a biopsy and histopathological examination.

Results: On comparative analysis, the sensitivity and specificity of Pap smear cytology were found to be 89.5% and 65.2%, respectively. The sensitivity and specificity of VIA were found to be 94.7% and 88%, respectively. The overall accuracy of VIA testing (93.2%) is more significant than that of Pap smear (68%).

Conclusion: According to our study, it is found that visual inspection with acetic acid is more diagnostically accurate than Pap smear cytology. Hence, VIA testing could be implemented as a primary screening tool with credence. Also, as learned from our study, the premalignant and malignant lesions are more common among elderly women living under a low socioeconomic status. Hence, these groups of women must be outreached and covered through effectively targeted screening programs.

Acceptability of text messages and knowledge change for cervical cancer screening: a Tanzanian mixed methods study

OBJECTIVES

To investigate the acceptability of a text message intervention and evaluate if text messages could increase knowledge of cervical cancer and screening.

DESIGN

This study was a substudy of a randomised controlled trial that used a mixed methods research design combining a quantitative questionnaire dataset and qualitative interview data. A before and after assessment was made of questionnaire responses. Acceptability was measured on a 6-point Likert scale and knowledge was measured through 16 binary true/false knowledge questions concerning cervical cancer and screening. Qualitative data were coded using a combined inductive-deductive approach.

SETTING

Ocean Road Cancer Institute in Dar es Salaam as well as Kilimanjaro Christian Medical Center and Mawenzi Regional hospital in the Kilimanjaro Region in Tanzania.

PARTICIPANTS

Human papillomavirus (HPV) positive women who had been randomised to the intervention group and received educative and reminder messages. Qualitative interviews were conducted with a subgroup of women in the intervention group.

INTERVENTIONS

15 one-way educative and reminder text messages.

RESULTS

A total of 115 women in the intervention group responded to both the baseline and follow-up questionnaire. Overall, women found it highly acceptable to receive text messages, and there was a trend towards acceptability rising between baseline and follow-up (mean: 0.22; 95% CI 0.00 to 0.44; p=0.05; t-statics=1.96). A significant increase in acceptability was found among the lowest educated and those who had not previously been screened. The qualitative interviews showed that the underlying reasons for the high acceptability rate were that the women felt someone cared for them and that the text messages were for their own benefits. The text messages did not improve the women's knowledge on cervical cancer and screening.

CONCLUSIONS

Educative and reminder text messages are highly acceptable among HPV-positive Tanzanian women; however, they do not increase the women's knowledge of cervical cancer and screening.

Barriers to adequate pain control among women with cervical cancer: exploring unmet pain control needs in Ghana

BACKGROUND

Pain because of cervical cancer is a significant health issue globally, especially in women with advanced disease. However, little is known about unmet needs for pain control in low-resource settings where the burden of cervical cancer is the greatest.

OBJECTIVE

This study aimed to quantify the level of pain that women with cervical cancer in Ghana experience, explore attitudes toward pain and pain medications, and determine the barriers to adequate pain control.

STUDY DESIGN

A cross-sectional survey was conducted on 100 adult women with a histopathologic diagnosis of cervical cancer presenting for care at Komfo Anokye Teaching Hospital in Ghana. In addition, a descriptive analysis was conducted among all participants and the subgroup of women who reported pain but did not report pain medication use.

RESULTS

Among 100 participants with cervical cancer, the mean age was 59.5 years, and the median parity was 6.0 (interquartile range, 5.0–6.0); moreover, most participants presented with inoperable stage II or greater cervical cancer (99 of 100 [99%]). Of 100 participants, 80 (80%) had pain caused by their cervical cancer, with more than half (51 of 100 [51%]) rating their pain as a 3, 4, or 5 on a 5-point scale. Most participants reported pain significant enough to impact their sleep (58 of 99 [58.6%]) and their ability to carry out daily activities (54 of 100 [54%]). Furthermore, 55 of 100 participants (55%) took pain medications in the last week; however, only 5 of 54 participants (9.3%) reported complete improvement in their pain, and most participants (30 of 54 [55.6%]) felt they needed a stronger pain medication. Barriers to adequate pain control included the healthcare provider's focus on pain, with 14.1% of women reporting that their healthcare providers never asked about their pain (14 of 99 [14.1%]). In addition, participants’ attitudes toward pain control demonstrated that 34 of 95 participants (35.8%) believed that they should be able to tolerate their cervical cancer pain without medication. Among participants who ever took pain medication, 16 of 58 (27.6%) were bothered that they took pain medication, and 19 of 58 (32.7%) were concerned that they used too much medication. Most participants were able to afford (51 of 58 [88%]) and access (56 of 58 [96.6%]) pain medications and did not worry their supply would run out (56 of 58 [96.6%]).

CONCLUSION

Most patients had significant pain because of cervical cancer, and many of them endorsed needing more pain medications than what they were prescribed. The etiologies of the unmet need for pain control included missed opportunities to discuss pain control at clinic visits and patients’ attitudes toward pain management. Financial and access barriers to obtaining pain medications were minimal.

Barriers and Facilitators to Cervical Cancer Screening in Western Kenya: a Qualitative Study

About nine out of 10 cervical cancer deaths occur in low-resource countries, with a particularly high burden in sub-Saharan Africa. The objectives of this study were to assess barriers and facilitators to cervical cancer screening in western Kenya from the perspectives of community members and healthcare providers. We conducted two focus groups with female community members (n = 24) and one with providers (n = 12) in Migori County, Kenya. Discussion guides queried about knowledge and awareness of cervical cancer prevention; structural, social, and personal barriers; and facilitators towards cervical cancer screening uptake. Group discussions were recorded, transcribed, and analyzed for emerging themes. Participants in both groups reported low awareness of HPV and cervical cancer screening in the community, and identified that as a main barrier to screening. Community members reported fear of pain and embarrassment as significant barriers to a screening pelvic exam. They also reported that providers' lack of knowledge and discomfort with a sensitive subject were significant barriers. A personal connection to cervical cancer and/or screening was associated with willingness to screen and awareness. Providers reported workload and lack of supplies and trained staff as significant barriers to offering services. Based on these findings, we identified three intervention components to address these facilitators and barriers to screening. They include utilizing existing social networks to expand awareness of cervical cancer risk and screening, training non-physician health workers to meet the demand for screening, and employing female-driven screening techniques such as self-collection of specimens for HPV testing. Cervical cancer prevention programs must take into account the local realities in which they occur. In low-resource areas in particular, identifying low-cost, effective, and culturally appropriate strategies for addressing poor screening uptake is important given limited funding. This study took a formative approach to identify facilitators and barriers to cervical cancer screening based on focus groups and interviews with community members and healthcare providers.

Assessment of Knowledge About Human Papillomavirus Vaccination Among Primary School Girls in Arba Minch Town, South Ethiopia, 2020 an Institution-Based Cross-Sectional Study

Purpose

This study aimed to determine the knowledge of human papillomavirus vaccination (PHV) and associated factors among primary school girls in Arba Minch town, South Ethiopia, in 2020. Hence, the levels of knowledge towards the HPV vaccination of girls were assessed and recommended to the concerned bodies. Clinically, this study could increase the acceptance of HPV vaccination after the intervention of the concerned bodies to improve adolescents’ knowledge levels. As a result, it could decrease the incidence of cervical cancer. Socially, this study may increase the research involvement of adolescents, communities, and stakeholder groups.

Patients and Methods

A school-based cross-sectional study involving 537 female students was conducted on January 24, 2020. The study participants were selected by a simple random sampling technique. A pre-tested questionnaire was used to collect the data. The logistic regression model was used to identify the statistically significant variables for knowledge of the human papillomavirus vaccination.

Results

The overall knowledge level of the participants in this study was 71.7%. Their main source of information is social media (41.74%), followed by medical staff (29.69%). Age ≥15 years old, AOR =3.74, 95% CI (2.20_6.37), P-value <0.001, grade level of 7 and 8, AOR =3.98, 95% CI (2.40_6.58), P-value <0.001, mother’s educational status of secondary and more than secondary, and father’s educational status of more than secondary, AOR=13.60, 95% CI (5.69_32.53) P-value <0.001, 22.27, 95% CI (8.23_60.30), P-value<0.001, 2.18, 95% CI (1.09_4.35), P-value 0.03, respectively, and access to HPV vaccination information (AOR = 8.65, 95% CI (3.92_19.07), P-value 0.001) were associated with overall knowledge.

Conclusion

Nearly three-fourths of the study participants were knowledgeable about human papillomavirus vaccination. Knowledge about the human papillomavirus vaccination shows a positive association with age, education level, parents’ educational status, and access to information sources.

Individual and community-level determinants of cervical cancer screening in Zimbabwe: a multi-level analyses of a nationwide survey

BACKGROUND

Despite the benefits of cervical cancer (CC) screening to reduce the disease burden, uptake remains limited in developing countries. This study aims to assess the individual and community-level determinants of cervical cancer screening among women of reproductive age in Zimbabwe.

METHODS

We analyzed data collected from 400 communities from the 2015 Zimbabwe Demographic and Health Survey with a sample size of 9955 women aged 15-49 years. The descriptive statistics and multi-level regression models adjusted for potential covariates were performed to examine the association between individual, household and community-level factors and the uptake of cervical cancer screening in women.

RESULTS

The mean (SD) age of women in Zimbabwe using cervical cancer screening was 27.9 (9.9) years. A relatively small proportion of women, i.e., only 13.4% had ever screened for cervical cancer, with higher screening rates observed in the following sub-groups: middle aged women 31-49 years (odds ratio (OR) = 2.01; 95% confidence intervals (CI) 1.72-2.34), and currently working (OR = 1.35; 95% CI 1.17-1.55), those with health insurance (OR = 1.95; 95% CI 1.63-2.34), used modern contraceptives (OR = 1.51; 95% CI 1.22-1.86), exposed to multiple media (OR = 1.27; 95% CI 1.03-1.58), those living in communities that had a high predominance of women with favorable attitude towards Intimate Partner Violence (IPV) against women (OR = 1.21; 95% CI 1.04-1.41) and a non-poor wealth index (OR = 1.54; 95% CI 1.14-2.05).

CONCLUSIONS

Our data shows a significantly low prevalence of cervical cancer screening among reproductive age women in Zimbabwe. To increase the uptake of cervical cancer screening, there is an urgent need both to implement behavioral interventions targeted at women from low socio-economic groups and to advocate for universal health coverage that includes financial risk protection to help all women realize their right to health.

Human papillomavirus vaccination uptake and its associated factors among adolescent school girls in Ambo town, Oromia region, Ethiopia, 2020

Background

The Human Papillomavirus (HPV) vaccine has offered a great promise to reduce the cervical cancer burden; its utilization (uptake) however has been lagging. However, the levels and factors associated with the uptake of the vaccine have not been well investigated, especially in the local context.

Objective

To assess the uptake of human papillomavirus vaccination and its associated factors among adolescent school girls in ambo town, Oromia, Ethiopia, 2020.

Methods

An institution-based cross-sectional quantitative study design supplemented with the qualitative inquiry was employed to assess Human Papillomavirus vaccination uptake and its associated factors among 422 adolescent school girls in Ambo town, central Ethiopia from December 1–30, 2020. The collected data were coded, entered, and cleaned by using Epi info 7.2.3 and exported to SPSS version 25 for analysis. Descriptive statistics were used to compute summary statistics and proportions. Both bivariate and multivariable logistic regression was employed to identify factors associated with HPV vaccine uptake. Adjusted odds ratio and 95% confidence interval were used for the strength and directions of association. A P-value of < 0.05 was used to declare statistical significance. Qualitative findings have been analyzed with manual thematic analysis.

Result

The proportion of HPV vaccination uptake among school girls in this study was 44.4%. Hearing about HPV vaccine [AOR = 2.50, 95%CI: (1.045–5.959)], availability of awareness creation [AOR = 2.53, 95%CI: (1.507–4.258)], and favorable attitude [AOR = 2.049, 95%CI: (1.153–3.64)] were the key identified factors associated with vaccination uptake. In addition, poor perception, fear of side effects, and misunderstanding were among the major factors identified by qualitative findings.

Conclusion

There was low uptake of HPV vaccination among the school Adolescents in the study area. Availability of awareness creation programs, favorable attitude towards HPV vaccine, and hearing about HPV vaccine was significantly associated with the uptake of the HPV vaccination. Therefore, awareness creation and behavior change education are mandatory to scale up the vaccination.

Prevalence and risk factors associated with precancerous cervical lesions among women in two cities in Cameroon

Introduction

cervical cancer is the fourth commonest cancer of women world-wide with increasing incidence in developing countries. This study determined the prevalence and assessed risk factors associated with precancerous cervical lesions among women in Cameroon.

Methods

this cross-sectional study enrolled 925 women participants of a screening campaign for precancerous cervical lesions from June to November 2018 in the selected hospitals. A convenience sampling technique was used and socio-demographic, sexual and reproductive data collected from consented participants by means of self-administered questionnaire. During the gynaecologic examination, a cervical smear was collected, stained by the Papanicolaou staining technique and the results classified according to the Bethesda 2014 guidelines. Frequency, percentage, Chi square and regression analysis were conducted using SPSS version 20 and p-value considered at 0.05.

Results

of the 925 participants aged 25-65 years (mean 40.2±10.2 SD), 113 (12.2%) had the lesions among whom 9 (7.9%) had atypical squamous cells of undetermined significance, 75 (66.4 %) had Low-grade squamous intraepithelial lesion and 29 (25.7%) had high-grade squamous intraepithelial lesion. Factors associated with the lesions were: age 1.85 [1.42-2.41; p= 0.001] and parity [OR= 1.46; 95% CI: 1.30-1.89; P= 0.004].

Conclusion

the prevalence of precancerous lesions was 12.2%. Age, parity were significant risk factors. Regular screening targeting the population at risk in this study becomes a priority.

Mapping Evidence on the Burden of Breast, Cervical, and Prostate Cancers in Sub-Saharan Africa: A Scoping Review

Background

Cancer remains a major public health problem, especially in Sub-Saharan Africa (SSA) where the provision of health care is poor. This scoping review mapped evidence in the literature regarding the burden of cervical, breast and prostate cancers in SSA.

Methods

We conducted this scoping review using the Arksey and O'Malley framework, with five steps: identifying the research question; searching for relevant studies; selecting studies; charting the data; and collating, summarizing, and reporting the data. We performed all the steps independently and resolved disagreements through discussion. We used Endnote software to manage references and the Rayyan software to screen studies.

Results

We found 138 studies that met our inclusion criteria from 2,751 studies identified through the electronic databases. The majority were retrospective studies of mostly registries and patient files (n = 77, 55.8%), followed by cross-sectional studies (n = 51, 36.9%). We included studies published from 1990 to 2021, with a sharp increase from 2010 to 2021. The quality of studies was overall satisfactory. Most studies were done in South Africa (n = 20) and Nigeria (n = 17). The majority were on cervical cancer (n = 93, 67.4%), followed by breast cancer (67, 48.6%) and the least were on prostate cancer (48, 34.8%). Concerning the burden of cancer, most reported prevalence and incidence. We also found a few studies investigating mortality, disability-adjusted life years (DALYs), and years of life lost (YLL).

Conclusions

We found many retrospective record review cross-sectional studies, mainly in South Africa and Nigeria, reporting the prevalence and incidence of cervical, breast and prostate cancer in SSA. There were a few systematic and scoping reviews. There is a scarcity of cervical, breast and prostate cancer burden studies in several SSA countries. The findings in this study can inform policy on improving the public health systems and therefore reduce cancer incidence and mortality in SSA.

Knowledge and willingness of parents towards child girl HPV vaccination in Debre Tabor Town, Ethiopia: a community-based cross-sectional study

Background

Cervical cancer is currently the second-leading cause of cancer death among women in Ethiopia. Vaccination against the human papillomavirus (HPV) is an effective primary prevention strategy for HPV-related illnesses. The knowledge and willingness of parents toward the HPV vaccine are crucial to increasing the uptake of the vaccine. The vaccine's acceptance by children and young adolescents is dependent on parental consent. Therefore, this study aimed to assess knowledge, willingness, and associated factors of the human papillomavirus vaccine among parents of girls aged 9–14 years at Debre Tabor Town.

Method

A community-based cross-sectional study was conducted among participants from December 10, 2020, to January 15, 2021. A simple random sample technique was used to include 638 participants. A structured face-to-face interviewer-administered questionnaire was used to collect data. The data were entered and analyzed using Epi-Data and SPSS software, respectively. Bivariate and multivariable analyses were used to examine the association. The Odds Ratio (OR), 95% CI, and p-values less than 0.05 were used to determine the statistical association.

Results

Thirty-five percent (35.4%, 95% CI = 31.4%, 38.8%) and 44.8% (95% CI = 40.40%, 48.67%) of participants were knowledgeable about HPV vaccination and willing to get it, respectively. Being government employees (AOR = 5.46, 95% CI = 2.42, 9.34), and having a family history of sexually transmitted diseases (STD) (AOR = 1.76, 95% CI = 1.14, 2.72) were significantly associated with knowledge of the human papilloma virus (HPV) vaccine. Participants’ age (AOR = 1.43, 95% CI = 1.16, 2.87), secondary education and above (AOR = 1.70, 95% CI = 1.05, 2.74), fear of HPV infection (AOR = 2.29, 95% CI = 1.21, 4.32), and having good knowledge of the HPV vaccine (AOR = 3.30, 95% CI = 2.21, 4.93) were significantly associated with willingness to receive the HPV vaccine.

Conclusion and recommendation

The knowledge and willingness of parents toward the HPV vaccine were low. Then, health officials should boost HPV vaccination promotion through public media. In schools, churches, mosques, and health facilities, health extension workers and health professionals provide information about the HPV vaccine for the parents. Mixed quantitative and qualitative studies are preferable for future research to address “why” issues.

Infection with the Human Papillomavirus (HPV) causes nearly 99% of cervical cancer cases and more than 20% of breast, neck, and anogenital cancers. The HPV vaccines protect against high-risk types of HPV (types 16 and 18), which account for approximately 70% of cervical cancers. Global coverage of the HPV vaccine was 39.7%, with high-income countries (68%), middle-income countries (28%), and lower-middle-income countries (2.7%). For different reasons, cervical cancer screening is very poor in Ethiopia (below 2%). Cervical cancer is mostly asymptomatic more than 20 years after infection. Primary prevention (enhancing the HPV vaccine) is the best way to protect women from cervical cancer. Adolescents’ uptake and acceptance of the vaccine depend on parental consent. Assessing parental knowledge and willingness at a community level is very crucial.

A simple random sample technique was used to include 638 participants. A structured and pre-tested face-to-face interviewer-administered questionnaire was used to collect the data. The data were entered and analyzed using Epi-Data, and SPSS software, respectively. Bivariate and multivariable analyses were used to examine the association.

Nearly one-third (35.4%) and less than half (44.8%) of participants were knowledgeable and willing to receive the HPV vaccination. The knowledge and willingness of the parents are significantly lower. Being government employees and having a family history of sexually transmitted diseases (STD) were factors affecting the knowledge of parents about the human papillomavirus vaccine. Participants’ age, secondary education and above, fear of HPV infection, and having good knowledge of the HPV vaccine were significantly associated with their willingness to use the HPV vaccine. The knowledge and willingness of the parents are significantly lower. Health officials and stakeholders should scale up HPV vaccine promotion through public media.

A Socio-Ecological Framework for Cancer Prevention in Low and Middle-Income Countries

Cancer incidence and mortality rates continue to rise globally, a trend mostly driven by preventable cancers occurring in low-and middle-income countries (LMICs). There is growing concern that many LMICs are ill-equipped to cope with markedly increased burden of cancer due to lack of comprehensive cancer control programs that incorporate primary, secondary, and tertiary prevention strategies. Notably, few countries have allocated budgets to implement such programs. In this review, we utilize a socio-ecological framework to summarize primary (risk reduction), secondary (early detection), and tertiary (treatment and survivorship) strategies to reduce the cancer burden in these countries across the individual, organizational, community, and policy levels. We highlight strategies that center on promoting health behaviors and reducing cancer risk, including diet, tobacco, alcohol, and vaccine uptake, approaches to promote routine cancer screenings, and policies to support comprehensive cancer treatment. Consistent with goals promulgated by the United Nations General Assembly on Noncommunicable Disease Prevention and Control, our review supports the development and implementation of sustainable national comprehensive cancer control plans in partnership with local communities to enhance cultural relevance and adoption, incorporating strategies across the socio-ecological framework. Such a concerted commitment will be necessary to curtail the rising cancer and chronic disease burden in LMICs.

Management of Psychosocial and Sexual Complains Among Cancer Patients in the African Context: A scoping review

Background

There is a lack of specialised psychosocial and sexual therapies for cancer patients in the African context.

Aim

This paper aims to highlight gaps in capacities of health care providers to address psychosocial and sexual needs of patients suffering from cancer disease, develop and share the proposed algorithm of psychosocial and sexual care management in the African context.

Methods

We conducted a scoping review of literature that highlights the psychosocial and sexual complications associated with cancer disease and its management, especially in the African context. A systematic search of bibliographic databases and websites including BioMed Central, PubMed Central, Taylor and Francis Online, Wiley online Library, EBSCOHOST databases using appropriate keywords on management of cancer in Africa was conducted between January 1, 2000 to March 31, 2021, using search words: ‘cancer; cancer treatment; ‘cancer management’; ‘cancer complications’; ‘psychosocial and sexual complications of cancer’. Identified publications were screened against selection criteria following the PRISMA guidelines.

Outcomes

Characteristics or psycho-social and sexual outcomes of cancer were examined and associated management charted in an excel framework with the 6 studies that met the eligibility criteria.

Results

A total of 6 studies were retrieved that met the eligibility criteria.

Clinical Translation

There is need to strengthen capacities of health care providers in the African health care system regarding the management of psychosocial and sexual complications associated with cancer disease.

Strengths and limitations

The study's utilised a rapid scoping review approach that aimed to shed some light regarding the gaps in cancer management, while also providing a much-needed solution to care for cancer survivors in the African context.

Conclusions

The study proposes a psychosocial and sexual algorithm of care to be utilised by health care providers for the management of psychosexual complications associated with cancer disease. The algorithm can assist and facilitate the integration of psychosocial and sexual cancer programs into existing health care services in primary health care facilities making it accessible to most patients.

A Brief Overview of Oncogenes and Signal Transduction Pathways in Gynecological Cancer

Gynecological cancer is the cancer that originates in the female reproductive system. According to the anatomical location of the cancer, it is distinguished into cervical, uterine, vaginal, ovarian, and vulvar cancer. Oncogenes and tumor catalytic genes play a key role in the genesis and development of gynecological cancer. This article presents the signaling pathways and expression of oncogenes that take place in the carcinogenesis of the female reproductive system.

Perceptions of cervical cancer care among Ethiopian women and their providers: a qualitative study

Background

Cervical cancer is the second most commonly diagnosed cancer among Ethiopian women, killing an estimated 4700 women each year. As the government rolls out the country’s first national cancer control strategy, information on patient and provider experiences in receiving and providing cervical cancer screening, diagnosis, and treatment is critical.

Methods

This qualitative study aimed to assess the availability of cervical cancer care; explore care barriers and sources of delay; and describe women’s and providers’ perceptions and experiences of care. We analyzed data from 45 informants collected at 16 health centers, district hospitals and referral hospitals in East Gojjam Zone and a support center in Addis Ababa. Thirty providers and ten women receiving care were interviewed, and five women in treatment or post-treatment participated in a focus group discussion. Deductive and inductive codes were used to thematically analyze data.

Results

Providers lacked equipment and space to screen and treat patients and only 16% had received in-service cervical cancer training. Consequently, few facilities provided screening or preventative treatment. Patients reported low perceptions of risk, high stigma, a lack of knowledge about cervical cancer, and delayed care initiation. All but one patient sought care only when she became symptomatic, and, pre-diagnosis, only half of the patients knew about cervical cancer. Even among those aware of cervical cancer, many assumed they were not at risk because they were not sexually active. Misdiagnosis was another common source of delay experienced by half of the patients. Once diagnosed, women faced multiple-month waits for referrals, and, once in treatment, broken equipment and shortages of hospital beds resulted in additional delays. Barriers to therapeutic treatment included a lack of housing and travel funds. Patient-provider communication of cancer diagnosis was often lacking.

Conclusions

In-service provider training should be intensified and should include discussions of cervical cancer symptoms. Better distribution of screening and diagnostic supplies to lower-level facilities and better maintenance of treatment equipment at tertiary facilities are also a priority. Expanded cervical cancer health education should focus on stigma reduction and emphasize a broad, wide-spread risk of cervical cancer.

Cervical cancer is the second most commonly diagnosed cancer among Ethiopian women, killing an estimated 4700 women each year. This study aimed to assess patient and provider experiences in receiving and providing cervical cancer screening, diagnosis, and treatment. We interviewed 30 midlevel providers and ten women receiving care and held a focus group discussion with five women who were receiving treatment or who had recently completed treatment. Patients reported bottlenecks and delays at each stage of care. Low perception of risk, high stigma, and a lack of knowledge about cervical cancer among both providers and patients, were significant sources of delay in initiating care. Few patients had been aware of cervical cancer before they were diagnosed and of those who were aware, many assumed that they were not at risk because they were not sexually active. Misdiagnosis was another common source of delay. Once diagnosed correctly, women faced multiple-month delays after referrals, and, once in treatment, broken equipment and a shortage of hospital beds resulted in additional delays. The most frequently mentioned barriers to care were a lack of housing and travel funds while receiving treatment in the capital. Patient-provider communication of cancer diagnosis was often poor. Our findings suggest the need to intensify in-service training for providers, focusing initially on alerting them to cervical cancer symptoms. Better distribution of screening and diagnostic supplies to lower-level facilities and better maintenance of treatment equipment at tertiary facilities should also be a priority.

Enhancement of Conventional and Photodynamic Therapy for Treatment of Cervical Cancer with Cannabidiol

Cervical cancer (CC) is the fourth most diagnosed cancer in women worldwide. Conventional treatments include surgery, chemo- and radiotherapy, however these are invasive and may cause severe side effects. Furthermore, approximately 70% of late-stage CC patients experience metastasis, due to treatment resistance and limitations. Thus, there is a dire need to investigate alternative therapeutic combination therapies. Photodynamic therapy (PDT) is an alternative CC treatment modality that has been clinically proven to treat primary CC, as well as to limit secondary metastasis. Since PDT is a non-invasive localized treatment, with fewer side effects and lessened resistance to dose repeats, it is considered far more advantageous. However, more clinical trials are required to refine its delivery and dosing, as well as improve its ability to activate specific immune responses to eradicate secondary CC spread. Cannabidiol (CBD) isolates have been shown to exert in vitro CC anticancer effects, causing apoptosis post treatment, as well as inducing specific immune responses, which obstruct tumor invasion and angiogenesis, and so hinder CC metastatic spread. This review paper discusses the current conventional and alternative PDT treatment modalities for CC, as well as their limitations over the last 10 years. It has a particular focus on the combinative administration of CBD with these treatments in order to prevent CC secondary migration and so possibly encourage future research studies to focus on this synergistic effect to eradicate CC.

Cervical cancer prevention in Africa: A policy analysis

BACKGROUND

Cervical cancer is a major public health challenge in Africa. We analyzed the presence and content of policies for the primary, secondary and tertiary prevention of cervical cancer in Africa, to identify areas of opportunity for policy strengthening in the region most affected by cervical cancer globally.

METHODS

We searched for publicly-available policy documents among countries in Africa. Using a data extraction form, we gathered data from these policies about key elements of primary, secondary and tertiary prevention approaches and activities based on World Health Organization (WHO) guidelines. We also contacted key stakeholders in each country to confirm these details. We summarized each country's policy details (summed score for each prevention stage and overall), and compared these scores across individual countries and groups of countries based on economic, policy and public health characteristics.

RESULTS

Most countries had at least one policy addressing some aspect of cervical cancer prevention. Primary and secondary prevention were more commonly addressed, and certain details like age of vaccination, screening age/interval and method, were frequently mentioned in these policies.

CONCLUSION

Countries with high HIV burden and relatively more donor financing for health had more comprehensive cervical cancer policies; there was no apparent association with cervical cancer mortality, female representation in government, or economic indicators (poverty prevalence or income inequality).

POLICY SUMMARY

There is room to improve cervical cancer policy comprehensiveness in Africa, and to bring these policies in line with evidence and expert recommendations. This analysis is timely given upcoming monitoring of the WHO Global Strategy to Accelerate the Elimination of Cervical Cancer as a Public Health Problem. These findings suggest some improvements in African cervical cancer policy, including increased inclusion of vaccination, but many topics remain under-specified. The influence of internal and external factors on policymaking should also be considered.

Cervical cancer treatment in Rwanda: Resource-driven adaptations, quality indicators, and patient outcomes

OBJECTIVE

Most cervical cancer cases and deaths occur in low- and middle-income countries, yet clinical research from these contexts is significantly underrepresented. We aimed to describe the treatment quality, resource-driven adaptations, and outcomes of cervical cancer patients in Rwanda.

METHODS

A retrospective cohort study was conducted of all patients with newly diagnosed cervical cancer enrolled between April 2016 and June 2018. Data were abstracted from medical records and analyzed using descriptive statistics, Kaplan Meier methods, and Cox proportional hazards regression.

RESULTS

A total of 379 patients were included; median age 54 years, 21% HIV-infected. A majority (55%) had stage III or IV disease. Thirty-four early-stage patients underwent radical hysterectomy. Of 254 patients added to a waiting list for chemoradiation, 114 ultimately received chemoradiation. Of these, 30 (26%) received upfront chemoradiation after median 126 days from diagnosis, and 83 (73%) received carboplatin/paclitaxel while waiting, with a median 56 days from diagnosis to chemotherapy and 207 days to chemoradiation. There was no survival difference between the upfront chemoradiation and prior chemotherapy subgroups. Most chemotherapy recipients (77%) reported improvement in symptoms. Three-year event-free survival was 90% with radical hysterectomy (95% CI 72-97%), 66% with chemoradiation (95% CI 55-75%), and 12% with chemotherapy only (95% CI 6-20%).

CONCLUSIONS

Multi-modality treatment of cervical cancer is effective in low resource settings through coordinated care and pragmatic approaches. Our data support a role for temporizing chemotherapy if delays to chemoradiation are anticipated. Sustainable access to gynecologic oncology surgery and expanded access to radiotherapy are urgently needed.

Digital health in oncology in Africa: A scoping review and cross-sectional survey

BACKGROUND

Low- and middle-income countries, especially in Africa, face a growing cancer burden. Adoption of digital health solutions has the potential to improve cancer care delivery and research in these countries. However, the extent of implementation and the impact of digital health interventions across the cancer continuum in Africa have not been studied.

AIMS

To describe the current landscape of digital health interventions in oncology in Africa.

METHODS

We conducted a scoping literature review and supplemented this with a survey. Following the PRISMA for Scoping Reviews guidelines, we searched literature in PubMed and Embase for keywords and synonyms for cancer, digital health, and African countries, and abstracted data using a structured form. For the survey, participants were delegates of the 2019 conference of the African Organization for Research and Training in Cancer.

RESULTS

The literature review identified 57 articles describing 40 digital health interventions or solutions from 17 African countries, while the survey included 111 respondents from 18 African countries, and these reported 25 different digital health systems. Six articles (10.5%) reported randomized controlled trials. The other 51 articles (89.5%) were descriptive or quasi-experimental studies. The interventions mostly targeted cancer prevention (28 articles, 49.1%) or diagnosis and treatment (23 articles, 40.4%). Four articles (7.0%) targeted survivorship and end of life, and the rest were cross-cutting. Cervical cancer was the most targeted cancer (25 articles, 43.9%). Regarding WHO classification of digital interventions, most were for providers (35 articles, 61.4%) or clients (13, 22.8%), while the others were for data services or cut across these categories. The interventions were mostly isolated pilots using basic technologies such as SMS and telephone calls for notifying patients of their appointments or results, or for cancer awareness; image capture apps for cervical cancer screening, and tele-conferencing for tele-pathology and mentorship. Generally positive results were reported, but evaluation focused on structure and process measures such as ease of use, infrastructure requirements, and acceptability of intervention; or general benefits e.g. supporting training and mentorship of providers, communication among providers and clients, and improving data collection and management. No studies evaluated individualized clinical outcomes, and there were no interventions in literature for health system managers although the systems identified in the survey had such functionality, e.g. inventory management. The survey also indicated that none of the digital health systems had all the functionalities for a comprehensive EHR, and major barriers for digital health were initial and ongoing costs, resistance from clinical staff, and lack of fit between the EHR and the clinical workflows.

CONCLUSION

Digital health interventions in oncology in Africa are at early maturity stages but promising. Barriers such as funding, fit between digital health tools and clinical workflows, and inertia towards technology, shall need to be addressed to allow for advancement of digital health solutions to support all parts of the cancer continuum. Future research should investigate the impact of digital health solutions on long-term cancer outcomes such as cancer mortality, morbidity and quality of life.

Human Papilloma Virus infection and cervical cancer among women who sell sex in Eastern and Southern Africa: A scoping review

OBJECTIVES

Women who sell sex have a high prevalence of human papilloma virus, which may cause cervical cancer. The objective of this review was to collate findings on prevalence, associated factors, screening, service provision and utilization of services in relation to human papilloma virus and cervical cancer among women who sell sex in Eastern and Southern Africa.

METHODS

A scoping review methodology was employed. Inclusion criteria were as follows: (1) empirical papers, (2) of studies conducted in Eastern and Southern Africa, (3) published in the last 10 years, and (4) addressing women who sell sex in relation to (5) human papilloma virus and cervical cancer. A thorough search of a range of databases surfaced 66 papers. Both authors applied inclusion and exclusion criteria, resulting in 14 papers being reviewed.

RESULTS

The reported prevalence of high-risk human papillomavirus virus varied between 23.6% and 70.5%. HIV sero-positivity, other sexually transmitted infections and Epstein-Barr virus were associated with human papilloma virus and high-grade cervical lesions. High-risk human papilloma virus was associated with women who reported younger age at first intercourse, non-barrier contraceptive use, and no history of condom use. For screening, there was overall agreement between physician- and self-collected samples. Contradictory results were found for visual inspection with acetic acid. Screening services utilization was associated with provider's recommendation, history of sexually transmitted infections, frequency of facility visit and history of vaginal examination. A diagonal programme led to an increase in screening, attributed to the targeted services.

CONCLUSIONS

Context is important in planning cervical cancer services. There is a need for enhanced sexually transmitted infections and viral management within cervical cancer prevention. Women who sell sex should be empowered in self-collection of stored-dry specimens, especially in resource-constrained regions. Cervical cancer screening services should be honed to the needs of women who sell sex.

LASSO and Bioinformatics Analysis in the Identification of Key Genes for Prognostic Genes of Gynecologic Cancer

The aim of this study is to identify potential biomarkers for early diagnosis of gynecologic cancer in order to improve survival. Cervical cancer (CC) and endometrial cancer (EC) are the most common malignant tumors of gynecologic cancer among women in the world. As the underlying molecular mechanisms in both cervical and endometrial cancer remain unclear, a comprehensive and systematic bioinformatics analysis is required. In our study, gene expression profiles of GSE9750, GES7803, GES63514, GES17025, GES115810, and GES36389 downloaded from Gene Expression Omnibus (GEO) were utilized to analyze differential gene expression between cancer and normal tissues. A total of 78 differentially expressed genes (DEGs) common to CC and EC were identified to perform the functional enrichment analyses, including gene ontology and pathway analysis. KEGG pathway analysis of 78 DEGs indicated that three main types of pathway participate in the mechanism of gynecologic cancer such as drug metabolism, signal transduction, and tumorigenesis and development. Furthermore, 20 diagnostic signatures were confirmed using the least absolute shrink and selection operator (LASSO) regression with 10-fold cross validation. Finally, we used the GEPIA2 online tool to verify the expression of 20 genes selected by the LASSO regression model. Among them, the expression of PAMR1 and SLC24A3 in tumor tissues was downregulated significantly compared to the normal tissue, and found to be statistically significant in survival rates between the CC and EC of patients (p < 0.05). The two genes have their function: (1.) PAMR1 is a tumor suppressor gene, and many studies have proven that overexpression of the gene markedly suppresses cell growth, especially in breast cancer and polycystic ovary syndrome; (2.) SLC24A3 is a sodium–calcium regulator of cells, and high SLC24A3 levels are associated with poor prognosis. In our study, the gene signatures can be used to predict CC and EC prognosis, which could provide novel clinical evidence to serve as a potential biomarker for future diagnosis and treatment.

20(S)-ginsenoside Rh2-induced apoptosis and protective autophagy in cervical cancer cells by inhibiting AMPK/mTOR pathway

20(S)-Ginsenoside Rh2 (GRh2) has various biological activities including anticancer effects. However, no reports have investigated the connection between autophagy and apoptosis in HeLa cells treated with 20(S)-GRh2. In this study, We found that 20(S)-GRh2 suppressed proliferation and induced apoptosis in HeLa cells by activating the intrinsic apoptotic pathway and causing mitochondrial dysfunction. 20(S)-GRh2 enhanced cell autophagy through promoted the phosphorylation of AMPK, depressed the phosphorylation of AKT and suppressed mTOR activity. Furthermore, treatment with the autophagy inhibitor 3-MA enhanced 20(S)-GRh2-induced apoptosis, while the autophagy inducer rapamycin promoted cell survival. Moreover, the apoptosis inhibitor Z-VAD-FMK significantly restrained the apoptosis and autophagy induced by 20(S)-GRh2 in HeLa cells. We found that 20(S)-ginsenoside Rh2-induced protective autophagy promotes apoptosis of cervical cancer cells by inhibiting AMPK/mTOR pathway.

Cervical Cancer Prevention in Low- and Middle-Income Countries

Cervical cancer is one of the commonest cancers afflicting women in low and middle income countries, however, both primary prevention with human papillomavirus vaccination, and secondary prevention with screening programs and treatment of preinvasive disease are possible. A coordinated approach to eliminating cervical cancer, as has been called for by the World Health Organization, requires a complex series of steps at all levels of a health system. This article outlines the current state of cervical cancer prevention in low and middle income countries, the innovations being employed to improve outcomes, and consideration of the next steps needed as we move towards global elimination.

Cervical cancer diagnosis and treatment delays in the developing world: Evidence from a hospital-based study in Zambia

Expedited diagnostic processes for all suspected cervical cancer cases remain essential in the effort to improve clinical outcomes of the disease. However, in some developing countries like Zambia, there is paucity of data that assesses factors influencing diagnostic and treatment turnaround time (TAT) and other metrics vital for quality cancer care. We conducted a retrospective hospital-based study at the Cancer Diseases Hospital (CDH) for cervical cancer cases presenting to the facility between January 2014 and December 2018. Descriptive statistics were used to summarize demographic characteristics while a generalized linear model of the negative binomial was used to assess determinants of overall TAT. Our study included 2121 patient case files. The median age was 49 years (IQR: ±17) and most patients (n = 634, 31%) were aged between 41 and 50 years. The International Federation of Gynaecology and Obstetrics (FIGO) Cancer stage II (n = 941, 48%) was the most prevalent while stage IV (n = 103, 5.2%) was the least. The average diagnostic TAT in public laboratories was 1.48 (95%CI: 1.21-1.81) times longer than in private laboratories. Furthermore, referral delay was 55 days (IQR: 24-152) and the overall TAT (oTAT) was 110 days (IQR: 62-204). The age of the patient, HIV status, stage of cancer and histological subtype did not influence oTAT while marital status influenced oTAT. The observed longer oTAT may increase irreversible adverse health outcomes among cervical cancer patients. There is a need to improve cancer care in Zambia through improved health expenditure especially in public health facilities.

Factors influencing cervical cancer screening practice among female health workers in Nigeria: A systematic review

Background

Cervical cancer is the most prevalent gynaecologic cancer in Nigeria. Despite being largely preventable through screening, cervical cancer is the second leading cause of cancer morbidity and mortality in Nigeria. To reduce the burden of cervical cancer in Nigeria, female health workers (FHWs) are expected to play an influential role in leading screening uptake and promoting access to cervical cancer education and screening.

Aim

The aim of this systematic review is to assess the factors influencing cervical cancer screening (CCS) practice among FHWs in Nigeria.

Methods

We conducted a systematic literature search across six (6) electronic databases namely MEDLINE, Embase, Scopus, African Index Medicus, CINAHL, and Web of Science between May 2020 and October 2020. Reference list and grey literature search were conducted to complement database search. Four reviewers screened 3171 citations against the inclusion criteria and critically appraised the quality of eligible studies. Narrative synthesis was used in summarising data from included studies.

Results

Overall, 15 studies met the inclusion criteria and were all quantitative cross‐sectional studies. Included studies sampled a total of 3392 FHWs in Nigeria. FHWs had a high level of knowledge and positive attitude towards CCS. However, CCS uptake was poor. Predominant barriers to CCS uptake were the cost of screening, fear of positive results, lack of test awareness, reluctance to screen, low‐risk perception, and lack of time. In contrast, being married, increasing age, awareness of screening methods, and physician recommendation were the most documented facilitators.

Conclusion

This study revealed that a complex interplay of socioeconomic, structural, and individual factors influences CCS among FHWs in Nigeria. Therefore, implementing holistic interventions targeting both health system factors such as cost of screening and infrastructure and individual factors such as low‐risk perception and fear of positive result affecting FHWs in Nigeria is critical to reducing the burden of cervical cancer.

Correlates of human papillomavirus vaccine knowledge and acceptability among medical and allied health students in Northern Nigeria

Prior to its planned introduction, we investigated predictors of baseline knowledge and acceptability of HPV vaccination among medical and allied health care students in Kano, northern Nigeria. A total of 410 medical, dental and allied health students completed structured validated questionnaires. Knowledge scores and acceptability of HPV vaccine were determined and adjusted odds ratios (AOR) for predictors of HPV knowledge and acceptability were derived from multivariate logistic regression models. Overall, 3.7% (n = 15), 30.7% (n = 126) and 65.6% (n = 269) of respondents had good, moderate, and poor knowledge of HPV, respectively. The majority 334 (81.5%) were willing to accept the HPV vaccine, but only 18 (4.4%) had received at least one dose of the vaccine. Knowledge of HPV was better among females, younger (<20 years) medical students, students at higher levels of study, sexually experienced students, and condom users. HPV vaccine acceptance was higher among female students in the faculty of allied health with a family history of cervical cancer and good or moderate knowledge of HPV. In conclusion, most students were willing to receive HPV vaccination, despite their sub-optimal level of knowledge and low vaccine uptake. We recommend piloting the HPV vaccine in health colleges and recruiting early adopters as peer educators and advocates.IMPACT STATEMENTWhat is already known on this subject? Human Papilloma Virus (HPV) vaccine has been introduced in over 80 countries in the past decade, but evidence suggests low awareness of HPV infection and the vaccine, especially in developing countries. Nigeria proposes to introduce the HPV vaccine as part of the routine immunisation program in early 2021.What do the results of this study add? The majority of medical and allied health students in Kano, Nigeria, were willing to receive HPV vaccination, despite their sub-optimal level of knowledge and low vaccine uptake. Vaccine acceptance was predicted by the respondent's sex, course of study, family history of cervical cancer and knowledge of HPV.What are the implications of these findings for clinical practice and/or further research? The findings could inform program implementation and evaluation as HPV vaccine uptake is scaled up across Africa.

Urban Poor Community Settings' Knowledge and Screening Practices for Cervical Cancer in Ibadan, Nigeria

PURPOSE

This study investigated knowledge and screening practices for cervical cancer among two urban poor community settings in Ibadan, Nigeria.

METHODS

A cross-sectional design was used. ODK tool was used to collect quantitative data among a sample size of 500 respondents. Data were analyzed using IBM SPSS version 21 for descriptive and inferential statistics. Scores for knowledge were on a scale of 0-39 points (0-18 low, 19-23 fair, and 24-39 high knowledge).

RESULTS

A majority of respondents (77.2%) had low knowledge of cervical cancer and were not aware (93.6%) of the Papanicolaou test (Pap smear test) or cervical cancer screening (91.2%). Very few women (10%) were aware of the human papillomavirus vaccine for the prevention of cervical cancer, 4% had been screened with the Papanicolaou test, and one woman (0.3%) with visual inspection with acetic acid. Four (1.1%) women had taken human papillomavirus vaccine before.

CONCLUSION

The findings of this study have underscored a necessity for increased awareness creation through health promotion interventions and strategies to alleviate low knowledge, prevention, and screening practices for cervical cancer in poor community settings in Nigeria.

Cervical cancer screening uptake in Sub-Saharan Africa: a systematic review and meta-analysis

OBJECTIVES

The objective of this study is to estimate the pooled uptake of cervical cancer screening and identify its predictors in Sub-Saharan Africa.

STUDY DESIGN

Systematic review and meta-analysis.

METHODS

We searched PubMed, EMBASE, CINAHL, African Journals OnLine, Web of Science and Scopus electronic databases from January 2000 to 2019. All observational studies published in the English language that reported cervical cancer uptake and/or predictors in Sub-Saharan Africa were initially screened. We assessed methodological quality using the Newcastle-Ottawa Scale. An inverse variance-weighted random-effects model meta-analysis was performed to estimate the pooled uptake and odds ratio (OR) of predictors with a 95% confidence interval (CI). The I² test statistic was used to check between-study heterogeneity, and the Egger's regression statistical test was used to check publication bias.

RESULTS

We initially screened 3537 citations and subsequently 29 studies were selected for this review, which included a total of 36,374 women. The uptake of cervical cancer screening in Sub-Saharan Africa was 12.87% (95% CI: 10.20, 15.54; I² = 98.5%). A meta-analysis of seven studies showed that knowledge about cervical cancer increased screening uptake by nearly five times (OR: 4.81; 95% CI: 3.06, 7.54). Other predictors of cervical screening uptake include educational level, age, Human Immune deficiency Virus (HIV) status, contraceptive use, perceived susceptibility and awareness about screening locations.

CONCLUSIONS

Cervical screening uptake is low in Sub-Saharan Africa as a result of several factors. Health outreach and promotion programmes to target these identified predictors are required.

Total ginsenosides induce autophagic cell death in cervical cancer cells accompanied by downregulation of bone marrow stromal antigen-2

Ginsenosides are important active components in Panax ginseng. In the present study, total ginsenosides (TGNs) were demonstrated to enhance autophagy by promoting acidic vacuole organelle formation, recruitment of enhanced green fluorescent protein-microtubule-associated protein light chain 3 and expression of autophagy-related factors in cervical cancer cell lines. TGN markedly increased the expression of p62 at the transcriptional level, but decreased p62 protein expression in the presence of actinomycin D. The autophagic regulatory effect was reversible. TGN (≤120 µg/ml) did not affect the proliferation of cervical cancer cells under normal culture conditions, but markedly inhibited the growth of serum-deprived cells. Treatment with an inhibitor of autophagy (3-methyladenine) impaired TGN-induced cell death. This suggested that TGN caused autophagic cell death. In addition, western blot analysis demonstrated that the protein level of bone marrow stromal antigen-2 (BST-2) was downregulated by TGN. Upregulation of BST-2 reduced cell death. The results of the combined actions of various monomeric ginsenosides in TGN provide the molecular basis to develop TGN as a promising candidate for cancer therapy.
