Cancer in Al-Qassim, Saudi Arabia: A retrospective study (1987-1995)

Outcomes of Early-stage Glottic Carcinoma Treated with Radiation Therapy: A Single Institution Experience

Objective: To evaluate the outcomes of radical intent radiation therapy in early glottic carcinoma (EGC), including local control rate (LCR), disease-free survival (DFS), death specific free survival (DSFS), and overall survival (OS) rates, in Saudi patients treated at a single institution. 

Materials and methods: This is an institutional review board (IRB) approved, retrospective study of 27 patients with T1-2 N0 M0, early glottic carcinoma (EGC) who were treated from 2010 to 2015 at our institution with different radiotherapy (RT) fractionation regimens. The regimens included six different fractionation schedules of radiotherapy (RT): 50 Gy (20 x 2.5 Gy) dose prescribed to 95% isodose line, 52.4 Gy (20 x 2.52 Gy), 63 Gy (28 x 2.25 Gy), 66 Gy (33 x 2 Gy), and 70 Gy (35 x 2 Gy). The cohort was stratified into two groups, ≤ 52.5 Gy (n=15) and > 52.5 Gy (n=12). The median follow-up of all patients was 31.7 months (range 7-82).

Results: The mean age of the cohort was 64.5 years (median 65, range: 41-83). Eleven patients (40.7%) had a history of smoking. The majority of the cohort was with T1a EGC (70.4%, n=19), and anterior commissure invasion was seen in three patients (11.1%). The mean RT doses were 55.6 Gy (range: 50-70). The five-year LCR, DFS, DSFS, and OS rates were 83.1%, 80.0%, 96.2%, and 92.6%, respectively. The LCR rates for those receiving a dose of 52.5 Gy or less were 61.3 months compared to 89.5 months for those who received more than 52.5 Gy (p=0.994). Non-smokers and patients with an unknown smoking history achieved a five-year LCR of 100%, while patients with a positive smoking history achieved a five-year LCR of 60.6% (p=0.044).

Conclusion: Radiation therapy for EGC in our patients showed reasonable five-year LCR with larynx preservation at 83.1%, DFS 80.0%, five-year OS rate 92.6%, and DSFS rate 96.2%. We found that smoking had a significant correlation with LCR. However, large prospective trials are warranted to evaluate the efficacy of overall treatment time, dose per fraction of above 2 Gy, and smoking effect.

Breast Cancer Knowledge and Screening Practice and Barriers Among Women in Madinah, Saudi Arabia

A breast screening program may help to reduce cancer mortality rates among women. However, the use of the screening program by women in Madinah city is low, and studies examining its practice and barriers of low uptake are sparse. To identify breast cancer knowledge, practice and screening barriers among women attending primary health centers (PHC) in Madinah, Saudi Arabia. A primary health center-based cross-sectional study was performed in Madinah city in 2015. A multistage stratified cluster sample was obtained and included 465 women (15 years and older) from five PHC. Data concerning socio-demographics, knowledge about breast cancer, and practice and barriers of mammography use were collected using a structured questionnaire. The mean age of the studied 465 women was 34.9 ± 12.2 years. Of these women, 27.7 and 38.5 % received mammography and performed breast self-examination, respectively. A high level of poor knowledge about breast cancer was detected in the overall studied women and those who never received a mammography, particularly knowledge related to the risk factors of breast cancer. The most important predictors of the barriers to mammography were incorrect beliefs about mammography and its procedures. A belief that mammography is painful was significantly associated with a 56 % reduction in its use (OR = 0.44; 95 % CI = 0.22-0.88). The high levels of poor knowledge about cancer breast observed in this study reflect the need for greater efforts to increase breast awareness education.

Awareness about Breast Cancer and Its Screening among Rural Egyptian Women, Minia District: a Population-Based Study

Background:

Recent global cancer statistics indicate rising global incidence of breast cancer and the increase is occurring at a faster rate in developing countries. Training women how to carry out breast self-examination (BSE) can help them to be alert to any abnormalities in their breasts to speedily seek medical consultation. Health behavior may be influenced by level of awareness about breast cancer.

Methods:

A cross-sectional community- based study aimed to assess the level of knowledge about breast cancer risk factors, early warning signs, screening approaches and related predictors. Also, to determine the extent of practice of breast self- examination (BSE) among rural women, Minia in the period from February to May 2016. A total of 600 women were randomly included in the study. A questionnaire included socio-demographic characteristics and information related to their knowledge about breast cancer. Data analysis was carried out using SPSS version 19.

Results:

Moderate and high knowledge scores were presented by 46.9 %. Nearly 40% of participants had the knowledge that smoking increased the likelihood of cancer breast and almost 30% of them affirmed that being obese or having a positive family history of cancer breast made them vulnerable to cancer breast. It was found that 28.7% and 18.2% of them knew that aging and nulliparity increased the likelihood of breast cancer. Participants with better knowledge score were 4.8 times more likely to practice BSE.

Conclusion:

This study revealed poor knowledge among rural women regarding cancer breast. BSE and clinical breast examination were not well practiced. It is recommended to create awareness programs about breast cancer and regular patterns of BSE.

Level of awareness of cervical and breast cancer risk factors and safe practices among college teachers of different states in india: do awareness programmes have an impact on adoption of safe practices?

BACKGROUND

Breast and cervical cancers are the most common causes of cancer mortality among women in India, but actually they are largely preventable diseases. Although early detection is the only way to reduce morbidity and mortality, there are limited data on breast and cervical cancer knowledge, safe practices and attitudes of teachers in India. The purpose of this study is to assess the level of awareness and impact of awareness programs in adoption of safe practices in prevention and early detection.

MATERIALS AND METHODS

This assessment was part of a pink chain campaign on cancer awareness. During cancer awareness events in 2011 at various women colleges in different parts in India, a pre-test related to cervical cancer and breast cancer was followed by an awareness program. Post-tests using the same questionnaire were conducted at the end of the interactive session, at 6 months and 1 year.

RESULTS

A total of 156 out of 182 teachers participated in the study (overall response rate was 85.7 %). Mean age of the study population was 42.4 years (range- 28-59 yrs). There was a significant increase in level of knowledge regarding cervical and breast cancer at 6 months and this was sustained at 1 year. Adoption of breast self examination (BSE) was significantly more frequent in comparison to CBE, mammography and the Pap test. Magazines and newspapers were sources for knowledge regarding screening tests for breast cancer in more than 60% of teachers where as more than 75% were educated by doctors regarding the Pap test. Post awareness at 6 months and 1 year, there was a significant change in alcohol and smoking habits. Major reasons for not doing screening test were found to be ignorance (50%), lethargic attitude (44.8%) and lack of time (34.6%).

CONCLUSIONS

Level of knowledge of breast cancer risk factors, symptoms and screening methods was high as compared to cervical cancer. There was a significant increase in level of knowledge regarding cervical and breast cancer at 6 months and this was sustained at 1 year. Adoption of BSE was significantly greater in comparison to CBE, mammography and the Pap test. To inculcate safe practices in lifestyle of people, awareness programmes such as pink chain campaign should be conducted more widely and frequently.

Cervical cancer in north-eastern Libya: 2000-2008

Libya is a country with a low population, listed under the EMRO. Using registers and patient records from a major primary oncology clinic, data was gathered from Libyan cervical cancer patients and various parameters were studied across 9 years. Out of 4,090 female cancer cases during the study period, 1.8% were cervical cancer (n = 74). The average age of presentation was 53 years, with most of the cases (60%, n = 44) being premenopausal. Approximately 65% (n = 48) of cervical cancer patients are diagnosed at later stages (i.e. stages III and IV). The majority of these cases are squamous cell carcinoma (83.8%, n = 62), while 16.2% (n = 12) were found to be adenocarcinoma. Patients with squamous cell carcinoma presented at later stages more often than those with adenocarcinoma. Human papilloma virus was strongly implicated in cervical cancer, with 94% (n = 63) of those who were tested being positive for HPV-16 (82.5%, n = 52) and HPV-18 (12.7%, n = 8). Diagnosis was most frequently made through biopsy (97.3%, n = 72) as opposed to Pap smears (2.7%, n = 2). Most Libyan patients were put through chemotherapy (75%, n = 55) and triple therapy (surgery with combined chemotherapy and radiotherapy) was the most common (38%, n = 28) modality of treatment. Comparisons were made between Libya and other nations, either in the developed world or neighbouring countries. The major problem of cervical cancer in Libya is delayed presentation and hence, all the recommendations focus on increased awareness for the populace, implementation of a national cancer control plan and a national screening programme.

Assessment of the quality of breast cancer care: a single institutional study from Saudi Arabia

OBJECTIVE

To evaluate the quality of operable breast cancer care in a tertiary care institution.

DESIGN

A retrospective analysis of all breast cancer patients seen in our institution between 1995 and 2000. Data were abstracted from the charts of these patients. Indicators were based on an international consensus conference and other publications.

SETTING

A tertiary care health care institution.

MAIN MEASURES

We evaluated the charts and calculated the percentage for which the internationally accepted quality care indicators were followed during the continuum of care. We also reviewed the histopathological reports to evaluate conformation with the accepted indicators.

RESULTS

Charts of 75 patients (four exclusions, three metastatic, and one male), diagnosed to have breast cancer during the study period were reviewed. Only 28 (37%) patients had triple assessment before a definitive surgical procedure. Pre-operative staging including a CT and bone scan was performed in 58 (77.3%). Among the 50 patients who had definite surgical intervention, the majority had mastectomy (44/50, 88%) whereas axillary dissection was performed in 46 (46/50, 92%). Estrogen and progesterone receptor status was reported in only four (4/50, 8%) and the exact tumor size in 24 (24/50, 48%) of the histopathological reports. Adjuvant chemotherapy was used in accordance with the international standards but radiotherapy was under-utilized.

CONCLUSION

Our study demonstrated that the quality of breast cancer care in this institution was below the accepted international standards. This study may be used to make interventions for improvement of quality in similar institutions all over the kingdom.
