Breast cancer screening in Saudi Arabia: free but almost no takers

The burden of disease in Saudi Arabia 1990-2017: results from the Global Burden of Disease Study 2017

BACKGROUND

Availability of data to assess the population health and provision and quality of health care in Saudi Arabia has been lacking. In 2010, Saudi Arabia began a major investment and transformation programme in the health-care sector. Here we assess the impact of this investment era on mortality, health loss, risk factors, and health-care services in the country.

METHODS

We used results of the Global Burden of Diseases, Injuries, and Risk Factors Study (GBD) 2017 to describe the levels and temporal patterns in deaths, health loss, risk factors, and health-care access and quality in the Saudi Arabian population during 1990-2010 (before the health-care investments and reform) and 2010-17 (during health-care investments and reform). We also compared patterns in health outcomes between these periods with those in the north Africa and the Middle East GBD region and the Gulf Cooperation Council countries.

FINDINGS

Age-standardised mortality in Saudi Arabia decreased from 1990 to 2010 (annualised rate of change of -0·58%), and this decrease was further accelerated from 2010 to 2017 (-2·20%). The north Africa and the Middle East GBD region also had decreases in mortality during these periods, but for 2010-17 the decrease was not as low as in Saudi Arabia (-1·29%). Transport injuries decreased from third ranked cause of disability-adjusted life-years in 2010 to fifth ranked cause in 2017 in Saudi Arabia, below cardiovascular diseases (ranked first) and musculoskeletal disorders (ranked second). Years lived with disability (YLDs) due to mental disorders, substance use disorders, neoplasms, and neurological disorders consistently increased over the periods 1990-2010 and 2010-17. Between 1990 and 2017, attributable YLDs due to metabolic, behavioural, and environmental or occupational risk factors remained almost unchanged in Saudi Arabia, with high body-mass index, high fasting plasma glucose concentration, and drug use increasing across all age groups. Health-care Access and Quality (HAQ) Index levels increased in Saudi Arabia during this period with similar patterns to the rest of the Gulf Cooperation Council countries and the north Africa and the Middle East GBD region.

INTERPRETATION

Decreases in mortality continued at greater rates in Saudi Arabia during the period of 2010-17 than in 1990-2010. HAQ Index levels have also improved. Public health policy makers in Saudi Arabia need to increase efforts to address preventable risk factors that are major contributors to the burden of ill health and disability.

Awareness of Breast Cancer among Female Students and Faculty from Najran University, Najran, Saudi Arabia

Background:

Breast cancer (BC) is the leading malignancy among women in Najran, Saudi Arabia. However, not much is known about the public’s awareness of BC. This study explored the general knowledge, early warning signs, risk factors and sources of information about BC.

Methods:

An online-based, anonymous, self-rating, cross-sectional and survey-based study was conducted from March-2019 to April-2019. Three-hundred female students and/or faculty from College of Medicine, Najran University (Najran, Saudi Arabia) participated in the study.

Results:

A total of 232 students (77.3%) and 68 faculty (22.7%) responded to the survey. Our study showed that nulliparity (83.8%) and early menarche before 12 years of age (29.7%) were the most pertinent obstetric risk factors of BC. Conversely, lack of physical activity (66.3%) and family history of BC (18%) were the most substantial non-obstetric risk factors of BC. According to pre-defined criteria, while the surveyed research subjects demonstrated ‘good’ general knowledge about BC (75.3%), they unfavorably exhibited ‘poor’ knowledge about the warning signs of BC (94.3%). The predictors of ‘good’ overall knowledge (general knowledge plus signs knowledge about BC) included age, marital status, educational level and family history (all p<0.05, two-tailed Chi-square test). Apart from the campaigns’ educational materials (43%), the top source of knowledge about BC was internet (33%), whereas the lowest ones were healthcare professionals (11.3%) and training workshops (7.3%).

Conclusions:

The surveyed research subjects harbored risk factors of BC and demonstrated ‘poor’ knowledge about the warning early signs of BC. We call for rigorous and well-crafted educational campaigns geared toward improving the awareness level of BC among women in Najran province.

Correlation between breast cancer and lifestyle within the Gulf Cooperation Council countries: A systematic review

BACKGROUND

In the six Gulf Cooperation Council countries (GCCCs), Bahrain, Saudi Arabia, Kuwait, Oman, Qatar and the United Arab Emirates, breast cancer (BC) is the greatest cause of cancer incidence and mortality. Obesity and physical inactivity are established risk factors for BC globally and appear to be more of a problem in high income countries like the GCCCs.

AIM

To determine whether obesity and physical inactivity are associated with BC incidence in the GCCCs using the United Kingdom as a comparator.

METHODS

This systematic review was carried out according to PRISMA guidelines. A cancer registry and a statistical data search was done to identify the BC incidence over the past two decades and the prevalence of obesity and physical inactivity in the GCCCs. Additionally, a systematic search of the databases, MEDLINE, Web of Science, and PubMed between 1999 and 2019 was performed to determine whether obesity and physical inactivity are risk factors for BC in the GCCCs. All papers were critically appraised according to their research methods and were assessed for quality and risk of bias.

RESULTS

BC was the top malignancy in each GCC country. Women tended to be diagnosed with BC at a younger age than women in the United Kingdom. The greatest 10-year increase in BC incidence was seen in Saudi Arabia (54.2%), approximately seven times the rate of increase seen in the United Kingdom (7.6%). The prevalence of obesity and physical inactivity was greater in all the GCCCs in comparison to the United Kingdom. A total of 155 full studies were reviewed of which 17 were included. Of those, eight looked at the prevalence of obesity and physical inactivity in the Gulf States and nine looked at these as risk factors for BC. Only one study found an association between BC and obesity (odds ratio = 2.29). No studies looked solely at the link between physical inactivity and BC.

CONCLUSION

The prevalence of obesity and physical inactivity was high within the GCCCs, but the majority of the included studies found no positive correlation between obesity or physical inactivity and BC. A high proportion of women in this study were pre-menopausal which could contribute to the negative findings.

Socioeconomic Inequalities in Uptake of Breast Cancer Screening among Saudi Women: A Cross-Sectional Analysis of a National Survey

Timely and adequate screening for breast cancer could improve health outcomes and reduce health costs. However, the utilization of free breast cancer screening services among Saudi women is very low. This study aims to investigate socioeconomic inequalities in breast cancer screening among Saudi women. The data of this study were extracted from the nationally representative Saudi Health Interview Survey, conducted in 2013; the study included 2786 Saudi women. Multivariate logistic regression, the concentration curve, and the concentration index were used to examine, illustrate, and quantify income- and education-related inequalities in three outcomes: Knowledge about self-breast examination (SBE), clinical breast examination (CBE) received in the last year, and mammography, that has ever been previously carried out. Results showed a marked socioeconomic gradient in breast cancer screening services. The concentration index by income was 0.229 (SBE), 0.171 (CBE), and 0.163 (mammography). The concentration index by education was 0.292 (SBE), 0.149 (CBE), and 0.138 (mammography). Therefore, knowledge about breast cancer screening, and the utilization of screening services, were more concentrated among richer and better-educated women. Poorer and less educated women had less knowledge about self-breast examination, and had considerably less adherence to clinical breast examination and mammography. The findings are helpful for policy makers to devise and implement strategies to promote equity in breast cancer screening among Saudi women.

Mammography uptake among the female staff of King Saud University

Background:

Breast cancer is having a major impact on women's health worldwide. Early detection is the best defense against the associated morbidity and mortality of the disease.

Objectives:

To assess the level of mammography uptake among working Saudi women and identify the obstacles and barriers that negatively affect it. In addition, to identify the most effective sources of breast-cancer-related information and early detection screening.

Method:

We conducted a cross-sectional study of women employees of King Saud University aged 40 years and above on March–May 2015 using a self-report questionnaire.

Results:

A total of 229 participants were recruited from the female staff of King Saud University. Of the participants, 34% were aged 41 years or above, approximately 66% were married, 53.3% had a bachelor's degree, and 61.1% worked as administrators; further, 64.6% had a history of breastfeeding. The rate of mammography uptake was 51.5%. Univariate logistic regression indicated that age, education, and being single predict the rate of mammography uptake. However, multivariate logistic regression indicated that earlier age significantly predicts a higher risk of a low rate of mammography uptake. The main obstacle negatively affecting mammography uptake was ineligible criteria (21.8%). The main sources of information regarding breast cancer were awareness campaigns and television and radio (45.4% and 43.7%, respectively).

Conclusion:

The participants' rate of mammography uptake, awareness of mammograms, the risk factors, and signs of breast cancer were low. To improve breast-cancer mortality rates in Saudi Arabia, earlier detection of breast cancer through increasing awareness of mammograms is of paramount importance.

Prevalence of the co-prescription of tamoxifen and CYP2D6 inhibitors in Saudi population: A cross sectional study

Consumption of Cytochrome P450 2D6 (CYP2D6) inhibiting drugs along with tamoxifen treatment results in decrease in plasma concentration of endoxifen, the major active tamoxifen metabolite. Simultaneous use of CYP2D6 inhibitors, such as selective serotonin reuptake inhibitors (SSIs), as well as lesser tamoxifen adherence may negatively impact tamoxifen efficacy in patients with breast cancer. The objective of our study was to assess the co-prescription of CYP2D6 inhibitors and tamoxifen use and also to relate concomitant CYP2D6 inhibitor use and tamoxifen adherence to breast cancer in Riyadh, Saudi Arabia. All patients treated for breast cancer who had at least one tamoxifen prescription in their electronic medical records (EMRs) from June 2015 to June 2017 were included. Patients who had other adjuvant hormonal therapy were excluded from the study. In total, 499 patients (25 males and 474 females) with breast cancer using tamoxifen were included. Our study was purely observational study revealed that prescription of weak inhibitors with tamoxifen increased in the second year as opposed to decrease in the prescription of strong inhibitors. Also, a substantial percentage of patient population were found to be non-adherent to the tamoxifen therapy in this study.

Can Breast Self-examination and Clinical Breast Examination Along With Increasing Breast Awareness Facilitate Earlier Detection of Breast Cancer in Populations With Advanced Stages at Diagnosis?

Breast cancer is the most common form of cancer among women worldwide. Early detection is central to improving disease outcomes. Three main screening methods - mammography, breast self-examination (BSE), and clinical breast examination (CBE) - have been developed and tested in Western nations. There is ongoing debate regarding the efficacy of BSE and CBE in terms of mortality reduction, and a number of international organizations no longer recommend them as screening methods. In technically less developed countries, however, where women are usually diagnosed with breast cancer at advanced stages and younger ages, the benefits of BSE and CBE might outweigh the harm and facilitate early detection of breast cancer. This paper reviews the history of BSE and CBE and discusses their value as early detection methods. It can contribute to informed decision-making by health policy-makers and clinicians who are involved in breast cancer screening in the developing world to improve women's well-being.

Adaptation and validation of the Arabic version of self-efficacy scale for mammography. A report on psychometric properties

Objectives:

To culturally adapt and validate a mammography-specific self-efficacy (MSSE) scale into Arabic for the Saudi Arabian context.

Methods:

A methodological study aimed at tool translation and adaptation conducted in primary healthcare centers in As Madinah, Saudi Arabia between March 2016 and May 2016. The MSSE scale was translated and adapted into Arabic using standard procedures. Content and face validity were investigated. Confirmatory factor analysis and reliability analysis were used to determine the scale’s psychometric properties.

Results:

The scale showed a good internal consistency (Cronbach’s alpha=0.88). The confirmatory factor analysis supported the scale’s single-factor structure and the goodness-of-fit indices confirmed the model’s good fit (comparative fit index=0.961, Tucker-Lewis index=0.943, root-mean-square error of approximation=0.076, and standardized root-mean-square residual=0.045). Women who had a mammogram in the last 2 years scored significantly higher on the scale (39±6.2) than women who had never received a mammogram (35.88±7.2; p=0.009).

Conclusion:

The study confirmed that the scale’s Arabic version has good psychometric properties, using reliability analysis, confirmatory factor analysis, and extreme groups validation. The scale is likely to be useful for evaluating interventional studies aimed at improving mammography screening participation rates.

Breast, cervical and colorectal cancer screening in adults with diabetes: a systematic review and meta-analysis

AIMS/HYPOTHESIS

Individuals with diabetes are at increased risk of developing and dying from cancer. Evidence-based guidelines recommend universal screening for breast, cervical and colorectal cancer; however, evidence on the uptake of these tests in individuals with diabetes is mixed. We conducted a meta-analysis to quantify the association between diabetes and participation in breast, cervical and colorectal cancer screening.

METHODS

MEDLINE, EMBASE and CINAHL were searched systematically for publications between 1 January 1997 and 18 July 2018. The search was supplemented by handsearching of reference lists of the included studies and known literature reviews. Abstracts and full texts were assessed in duplicate according to the following eligibility criteria: study conducted in the general population; diabetes included as a predictor vs a comparison group without diabetes; and breast (mammography), cervical (Papanicolaou smear) or colorectal (faecal and endoscopic tests) cancer screening uptake included as an outcome. Random-effects meta-analyses were performed using the most-adjusted estimates for each cancer site.

RESULTS

Thirty-seven studies (25 cross-sectional, 12 cohorts) were included, with 27 studies on breast, 19 on cervical and 18 on colorectal cancer screening. Having diabetes was associated with significantly lower likelihood of breast (adjusted OR 0.83 [95% CI 0.77, 0.90]) and cervical (OR 0.76 [95% CI 0.71, 0.81]) cancer screening, relative to not having diabetes. Colorectal cancer screening was comparable across groups with and without diabetes (OR 0.95 [95% CI 0.86, 1.06]); however, women with diabetes were less likely to receive a colorectal cancer screening test than women without diabetes (OR 0.86 [95% CI 0.77, 0.97]).

CONCLUSIONS/INTERPRETATION

Our findings suggest that women with diabetes have suboptimal breast, cervical and colorectal cancer screening rates, compared with women without diabetes, although the absolute differences might be modest. Given the increased risk of cancer in this population, higher quality prospective evidence is necessary to evaluate the contribution of diabetes to cancer screening disparities in relation to other patient-, provider- and system-level factors.

Knowledge, Attitudes, and Practices of Breast Cancer Screening Methods Among Female Patients in Primary Healthcare Centers in Najran, Saudi Arabia

The aim of the present study was to evaluate the knowledge, attitude, and practice of breast cancer screening methods among female patients attending five primary healthcare centers in Najran, Saudi Arabia. A cross-sectional survey was conducted on 500 female patients, and a direct interview questionnaire was used to collect data. Our results indicated a low knowledge about breast cancer, breast self-examination, mammogram and clinical breast examination was 54.4%, 56%, 90.4%, and 83.8%, respectively. Nineteen percent of patients demonstrated a high knowledge of breast self-examination. Breast self-examination was performed by 35% of patients, whereas 15% of patients received mammograms and 19.8% clinical breast examinations. The most common barrier for screening methods of breast cancer was that patients were unaware of half of the screening methods. A total of 20.6% of women did not perform breast self-examinations because they were not well trained, and 26.4% of women did not receive clinical breast examinations because there was no female doctor available. The main source of information among the women patients was social media (52.4%), whereas 8.8% received information through their healthcare provider. In summary, the majority of women demonstrated poor knowledge about breast cancer and screening methods. Additional effort should be put forth through women's healthcare providers to increase the awareness of breast cancer screening. That means we need to continue emphasizing the importance of primary healthcare for early detection of breast cancer in the early stages.

Determinants of breast cancer in Saudi women from Makkah region: a case-control study (breast cancer risk factors among Saudi women)

BACKGROUND

There are various factors that play a major role in influencing the overall health conditions of women diagnosed with breast cancer. The population of women in Makkah region are diverse, therefore it is significant to highlight the possible determinants of breast cancer in this population. This is a case-control study that assessed determinants of breast cancer including socioeconomic factors, health-related characteristics, menstrual histories and breastfeeding among postmenopausal women in Makkah region in Saudi Arabia.

METHODS

A total of 432 female participants (214 cases and 218 controls) were recruited for this study. A validated questionnaire was completed by trained dietitians at King Abdullah Medical City Hospital in the Makkah region of Saudi Arabia.

RESULTS

Results displayed that determinants of breast cancer were associated significantly (P < 0.05) with unemployment, large family size, lack of knowledge and awareness about breast cancer, obesity, sedentary lifestyle, smoking, starting menarche at an early age, as well as hormonal and non-hormonal contraceptive use. There was no effect of diabetes, hypertension, hyperlipidemia, and duration of breastfeeding on the incidence of breast cancer.

CONCLUSION

In summary, the results of this study accentuate the possible effect of socioeconomic factors, health-related characteristics and menstrual history on the incidence of breast cancer in postmenopausal women in the Makkah region. Education programs should be applied to increase breast cancer awareness and possibly decrease its incidence.

Knowledge, attitudes, and practices related to breast cancer screening among female health care professionals: a cross sectional study

BACKGROUND

Incidence of breast cancer in the Kingdom of Saudi Arabia (KSA) has increased in recent years. Screening helps in early detection of cancer and early diagnosis and timely treatment of breast cancer lead to a better prognosis. Women in the healthcare profession can have a positive impact on the attitudes, beliefs, and practices of general public. Therefore, it is important that the healthcare workers themselves have adequate knowledge and positive attitudes. We conducted a study to assess the knowledge, attitudes, and practices related to breast cancer screening among female healthcare professionals.

METHODS

A cross-sectional study was conducted on female health professional of KFMC (King Fahad Medical City). Data was collected using a pre-designed, tested, self-administered questionnaire. The questionnaire included specific sections to test the participants' knowledge, attitude, and practices related to cervical cancer and its screening. Data analysis was done using descriptive statistics.

RESULTS

A total of 395 health care workers participated in this study. The mean age of the participants was 34.7 years. Participants included physicians (n = 63, 16.0%), nurses (n = 261, 66.1%), and allied health workers (n = 71, 18.0%). Only 6 (1.5%) participants had a good level of knowledge of breast cancer and 104 (26.8%) participants demonstrated a fair level of knowledge. Overall, 370 (93.7%), 339 (85.8%), and 368 (93.2%) participants had heard of breast self-examination, clinical breast examination, and mammography, respectively. A total of 295 (74.7%) participants reported practicing breast self-examination, 95 (24.1%) had undergone clinical breast examination, and 74 (18.7%) had ever undergone mammography.

CONCLUSION

The knowledge, attitudes, and practices related to breast cancer screening were found to be lower than expected. Active steps are required to develop educational programs for the health care staff, which might empower them to spread the knowledge and positively influence the attitudes of female patients in the hospital.

Effect of Health Education on Female Teachers' Knowledge and Practices Regarding Early Breast Cancer Detection and Screening in the Jazan Area: a Quasi-Experimental Study

Educational programs are important tools for breast cancer prevention. The purpose of this study was to assess the effectiveness of health education in improving the knowledge and practices of female teachers regarding screening tools and the early detection of breast cancer. A two-group quasi-experimental design was conducted among 150 female teachers, who were selected from 75 schools of the Jazan General Administration of Education. Schools were chosen by a simple cluster randomization method and non-randomly assigned to either the intervention or control group. Eligible participants were recruited by a simple randomization method, proportional to the total number of teachers at each school. Those in the intervention group (n = 75) were compared to the control group (n = 75) at baseline, as well as at 6 weeks and 3 months post-intervention. Knowledge of breast cancer screening tools was measured using a modified version of the Breast Cancer Knowledge test. Breast self-examination, clinical breast examination, and mammography practices were also measured. Compared to the control group, the intervention group showed a statistically significant increase in knowledge and practice levels at both 6 weeks and 3 months post-intervention. Thus, the results of this study provide evidence that group health education programs are effective in improving breast cancer knowledge and practices in female teachers. Clinical Trial Registration number: NCT03398057 .

Estimation of cancer risks during mammography procedure in Saudi Arabia

The aims of the present work were to quantify radiation doses arises from patients' exposure in mammographic X-ray imaging procedures and to estimate the radiation induced cancer risk. Sixty patients were evaluated using a calibrated digital mammography unit at King Khaled Hospital and Prince Sultan Center, Alkharj, Saudi Arabia. The average patient age (years) was 44.4 ± 10 (26-69). The average and range of exposure parameters were 29.1 ± 1.9 (24.0-33.0) and 78.4 ± 17.5 (28.0-173.0) for X-ray tube potential (kVp) and current multiplied by the exposure time (s) (mAs), respectively. The MGD (mGy) per single projection for craniocaudal (CC), Medio lateral oblique (MLO) and lateromedial (LM) was 1.02 ± 0.2 (0.4-1.8), 1.1 ± 0.3 (0.5-1.8), 1.1 ± 0.3 (0.5-1.9) per procedure, in that order. The average cancer risk per projection is 177 per million procedures. The cancer risk is significant during multiple image acquisition. The study revealed that 80% of the procedures with normal findings. However, precise justification is required especially for young patients.

Male Partners' Knowledge, Attitudes, and Perception of Women's Breast Cancer in Abha, Southwestern Saudi Arabia

Background: Breast cancer (BC) is ranked as the most frequently diagnosed cancer site among women in Saudi Arabia. Several studies in Saudi Arabia have reported low awareness of BC and significant obstacles to early presentation among Saudi women. A key sociocultural obstacle against breast screening and early detection of BC in several conservative cultures is that men manage women’s choices and activities. The aim of this research is to find out the key background knowledge, attitudes, and related practice among male partners in the city of Abha in relation to women’s BC prevention and means for early detection. Methods: A cross-sectional study targeting husbands aged 20 years or older chosen from the outpatient clinics in the Urban Primary Health Care Centers in Abha City. Through questionnaires, interview data were collected regarding knowledge about BC and wife practices and attitudes towards BC. Results: The study included 832 husbands. The study showed that only 20.2% (95% confidence interval (CI): 19.9–24.1) of husbands had heard about mammography and only 22.1% had heard about breast self-examination among women as a screening test for BC. The most commonly mentioned variations that might occur in relation to BC were size changes (45.6%). The leading source of BC knowledge was from television (48.9%), and the least-mentioned source of information was healthcare workers (22.4%). Husbands mentioned that only 9.3% of wives had been examined before by mammography. In a multivariate logistic regression of male factors associated with wives’ practices and attitudes towards BC, only good knowledge among husbands was a significant factor. Conclusions: The study documented the low level of BC knowledge among male partners. There is an urgent need to pay more consideration to disseminating awareness among men, as they are associates, and they must be armed with proper awareness. There is an urgent demand for establishing a national program and educational campaigns towards BC. Stressing the advantages and access to free mammography is necessary.

Breast cancers missed during screening in a tertiary-care hospital mammography facility

BACKGROUND

Breast cancer is the most common cancer in females worldwide. Screening with mammography for early breast cancer detection is standard community practice in many countries.

OBJECTIVE

Identify causes of missed breast cancers during screening.

DESIGN

Retrospective, observational.

SETTING

Department of radiology at a tertiary-care hospital mammographic screening facility.

PATIENTS AND METHODS

All women who came with initial negative screens from July 2015 to July 2018 were retrospectively reviewed and followed-up for their second or subsequent mammographic screening. Missed breast cancer was defined as a cancer that was detected on a subsequent mammogram with an initial negative screen. Mammograms were interpreted by two radiologists as per BIRADS (Breast Imaging Reporting and Data System) lexicon. Causes of missed breast cancers were categorized as imaging acquisition (IA), imaging feature (IF) and imaging interpretation (II). True (occult) incident breast cancers were also documented. Percentage estimations for these causes were calculated.

MAIN OUTCOME MEASURES

Breast cancer detection on follow-up screening.

SAMPLE SIZE

943 women.

RESULTS

Of 15 (1.6%) screening-detected breast cancers, 7 cases (46.6%) were missed on the initial screen; 3 (43%) of these were II related, 2 (28.5%) of each were IA and IF. The remaining true (occult) cases were detected on either the second (5 cases) or third screens (3 cases).

CONCLUSION

Improved screening facilities, quality mammographic acquisition and interpretation, double reading, and implementation of an organized screening program may help to avoid missed breast cancers.

LIMITATIONS

Retrospective, small sample, single center, and short duration study.

CONFLICT OF INTEREST

None.

National screening programs in Saudi Arabia: Overview, outcomes, and effectiveness

In 2016, the government of Saudi Arabia launched the National Transformation Program to ensure the realisation of Kingdom's Vision 2030. One of the strategic objectives is Health Promotion against Health Risks (Public Health System and Health Disasters Management). The new Institutional Transformation and Health Care Model involves actions focusing on diseases prevention and strengthening the primary health care system. Success of the new Health Care Model in Saudi Arabia is only possible when considering assessment of factors influencing national prevalence of health risk factors and early detection of chronic diseases. This notion mandates availability of national screening programs that are able to identify individuals at risk or asymptomatically suffering from chronic diseases. This review is aiming to provide an overall overview of current governmental national screening programs in Saudi Arabia, to assess utilisation and outcomes of screening services in Saudi Arabia and assessment of effectiveness of current national screening programs.

The use of complementary and alternative medicine among women with breast cancer in Saudi Arabia

PURPOSE

The purpose of the study was to explore the frequency of use of complementary and alternative medicine (CAM) therapies among women with breast cancer in Saudi Arabia.

DESIGN

A descriptive cross-sectional study design was used with face-to-face interviews using a structured questionnaire.

SAMPLE

A convenient sample of 85 Saudi women with breast cancer who were undergoing cancer treatment was recruited from the Oncology Department of King Faisal Hospital, Jeddah, Kingdom of Saudi Arabia.

METHODS

Using structured questionnaire "Use of Complementary Therapies Survey," consisted of diet and nutritional supplements, stress-reducing therapies, and other traditional treatments.

RESULT

Participants were predominantly married (76.5%), resided in an urban area (83.5%), unemployed (62%), and about half reported no income (49.4%). The mean age was 48 years. All participants reported using at least three or more CAM therapies (mean = 21.15, SD = 8.85) since their diagnosis. There were significant correlations between other CAM use and time since diagnosis (r_s = -0.33, p < .05). The highest usage of dietary and nutritional supplements occurred with honey, olive oil, antioxidants, Fennel flower seeds, and ginger. The highest stress reducing CAM techniques included reading the Holy Qur'ãn, and praying. For other traditional CAM therapies, positive thinking and relaxation techniques were the most frequent methods reported by women. Other CAM treatments involved ZamZam water and listening to music.

CONCLUSIONS

The use of complementary therapies among Saudi women with breast cancer is highly prevalent, with a predominance of interventions of religious background, indicating the strong influence of religion on peoples' lives, especially when people are faced with a life-threatening illness. The results of this study will guide future studies examining the efficacy of CAM on symptom management in Saudi Arabian women with breast cancer and other types of cancer.

Trends in the incidence and mortality of cancer in Saudi Arabia

Objectives:

To analyze the overall trends in cancer incidence and mortality in Saudi Arabia between 1990 and 2016.

Methods:

Data were retrieved through a Global Burden of Disease (GBD, 2016) database (Viz Hub) that is developed by the Institute for Health Metrics and Evaluation at the University of Washington.

Results:

The incidence of cancer increased around 26-fold for thyroid cancer; approximately 10-fold in breast, colon, bladder and uterine cancers; 8-fold for prostate cancer; 5-fold for renal cancer; 4-fold for pancreatic and ovarian cancer; 3.5-fold for lung cancer; 3-fold for liver cancer, and 2 folds for lymphoma, leukemia and gastric cancer. There was also an increase in the percentage of mortality due to cancer during this period. However, we noticed that the percentage of deaths due to cancer decreased after 70 years of age in Saudi Arabia population.

Conclusion:

The increases in the incidence of different types of cancer in the past decade could be due to the revolutionary change in socioeconomic status that has occurred in Saudi Arabia; therefore, a national plan should be established for cancer prevention, screening and therapy. Concerning mortality, the decrease in its percentage among elderly people could be due to biological factors that should be investigated in the future.

Preliminary investigation of mammographic density among women in Riyadh: association with breast cancer risk factors and implications for screening practices

PURPOSE

Improved mammographic sensitivity is associated with reduced mammographic density. This study aims to: provide a preliminary report on mammographic density among women in Riyadh; identify risk factors associated with mammographic density; and consider the potential implications for screening practices.

METHODS

Based on a cross-sectional design, we examined a total of 792 women using an area-based mammographic density method (LIBRA). Spearman's correlation, Mann-Whitney U, Kruskal-Wallis and binary logistic regression were used for analyses.

RESULTS

The study population had a mean age of 49.6 years and a high proportion of participants were overweight or obese (90%). A large number of women had low mammographic density, with a mean dense breast area of 19.1 cm² and percent density of 10.3 cm². Slightly more than half of the variations in the dense breast area and percent density models were explained by BMI. In the adjusted analyses, BMI, menopausal status, age at menarche and number of children remained statistically significant predictors.

CONCLUSION

Given the high proportion of women with low mammographic density, our findings suggest that women living in Riyadh may not require additional imaging strategies beyond mammography to detect breast cancers. The high proportion of obese women reported here and across Saudi Arabia suggests that mammographic density is less likely to have an adverse impact on mammographic sensitivity. Thus and to improve clinical outcomes among Saudi women, annual mammography and commencing screening at a younger age are suggested. Additional studies are required to shed further light on our findings.

Age distribution and outcomes in patients undergoing breast cancer resection in Saudi Arabia. A single-institute study

Objectives

In response to rising incidence and mortality we aimed to investigate the demographic characteristics of patients with operative breast cancer in our region.

Methods

We performed a retrospective study of 224 patients who underwent surgery for breast cancer at King Saud University Medical City, Riyadh, Kingdom of Saudi Arabia between 2005 and 2012.

Results

We identified a young population overall with a mean age of 48.8±12.2 years (range: 26-93 years). Survival rate were however similar across all age groups with a 10-year overall survival of 87%.

Conclusion

Patients in our study were generally younger than those with breast cancer in Western nations. However, unlike Western countries, young age was not associated with worse outcomes.

Breast Cancer Risk Factors: a Cross- Cultural Comparison between the West and the East

Background: The incidence of breast cancer in Lebanon is higher than any other Middle –Eastern country, is diagnosed at a younger age than women in Western countries, and is more aggressive and fatal. Therefore addressing risk factors in this population is of paramount importance. Methods: A descriptive cross-sectional, comparative design evaluated the risk factors for breast cancer in a convenient sample of 105 Lebanese-American women with 250 Lebanese. Odds Ratio, Chi square t-tests or ANOVA were used to compare the two groups’ risk factors and knowledge of screening tools. Associations found to be statistically significant were included in three multiple logistic regression models to estimate the odds of each variable for performing a mammography, a clinical breast exam (CBE) and a breast self-exam (BSE). Results: There were more Muslims in the Lebanese-American sample who perceived having a better income, and had a better understanding of the effectiveness of the mammogram, the CBE and the BSE. The Lebanese group reached menopause at an older age, t = 2.66, p = 0.05, smoked more, OR = 1.42, p = 0.001 and were five times more likely to live close to a main road or highway, OR = 5.75, p = 0.001 than the Lebanese-American group. The Lebanese- Americana group breast fed longer χ2= 11.68, p = .008, used contraceptives more, OR = 1.74, p = 0.027, exercised more, OR = 1.61, p < 0.001, and consumed more vegetables and fruits than their Lebanese counterparts, OR= 1.22, p = 0.002, and OR = 1.27 p = 0.001, respectively. For ever having a mammogram, the duration of breastfeeding (>6 months), effectiveness of the mammogram, and exercise were significant predictors. While for ever having a CBE, smoking, eating fruits, and exercise were significant. No variables were related to performing a BSE. Conclusion: The Lebanese women had higher risk factors for developing breast cancer, and had less knowledge of the benefits of breast cancer screening tools, calling for the importance of promoting healthy life styles and education.

Patterns, knowledge, and barriers of mammography use among women in Saudi Arabia

OBJECTIVES

To assess mammography utilization and knowledge, and to determine barriers associated with mammography utilization among Saudi women. Methods: We conducted a cross-sectional survey in 5 main geographic regions of Saudi Arabia from February 2015 to May 2015. The sample comprised women aged ≥40 years. Associations between socio-demographic factors and mammography use were tested using chi-square test. Predictors of mammography use were assessed by logistic regression. Results: A total of 3,245 women were surveyed, with 40% reporting ever having a mammogram. As indicated by the univariable analyses, older age (≥60 years), being single or divorced, having less than 2 children, not completing high school, and having a family history (hx) of breast cancer were significantly associated with never having a mammogram. Participants of older age (odds ratio [OR] 51-60 versus 41-50 = 0.6, 95% CI: 0.5-0.7 and OR less than 60 versus 41-50 = 0.5, 95% CI: 0.3-0.8), and divorced (OR divorced versus married = 0.6, 95% CI: 0.5-0.8] were less likely to have had a mammogram, while participants with no family hx of breast cancer (OR no family hx versus family hx = 1.5, 95%CI: 1.3-1.8)were more likely to have had a mammogram. Conclusion: Mammography utilization and knowledge are low in Saudi Arabia. Increasing the awareness of breast cancer screening through educational programs could help women overcome existing barriers and misconceptions.

Low Awareness of Breast Cancer and Considerable Barriers to Early Presentation Among Saudi Women at a Primary Care Setting

In Saudi Arabia, breast cancer is diagnosed at advanced stage compared to Western countries. Nevertheless, the perceived barriers to delayed presentation have been poorly examined. Additionally, available breast cancer awareness data are lacking validated measurement tool. The aim of this study is to evaluate the level of breast cancer awareness and perceived barriers to seeking medical care among Saudi women, using internationally validated tool. A cross-sectional study was conducted among adult Saudi women attending a primary care center in Riyadh during February 2014. Data were collected using self-administered questionnaire based on the Breast Cancer Awareness Measure (CAM-breast). Out of 290 women included, 30 % recognized five or more (out of nine) non-lump symptoms of breast cancer, 31 % correctly identified the risky age of breast cancer (set as 50 or 70 years), 28 % reported frequent (at least once a month) breast checking. Considering the three items of the CAM-breast, only 5 % were completely aware while 41 % were completely unaware of breast cancer. The majority (94 %) reported one or more barriers. The most frequently reported barrier was the difficulty of getting a doctor appointment (39 %) followed by worries about the possibility of being diagnosed with breast cancer (31 %) and being too busy to seek medical help (26 %). We are reporting a major gap in breast cancer awareness and several logistic and emotional barriers to seeking medical care among adult Saudi women. The current findings emphasized the critical need for an effective national breast cancer education program to increase public awareness and early diagnosis.

Perceived barriers to breast cancer screening among Saudi women at primary care setting

Introduction

Screening for breast cancer (BC) is of low rate in Saudi Arabia; although it is provided in the country free of charge to the population. This cross-sectional study aimed at investigating the perceived barriers towards BC screening in Al Hassa, Saudi Arabia.Participants and methods. A total of 816 adult Saudi women aged ≥ 30 years attending for routine primary health services or accompanying patients at the selected primary health care centers (PHCs) were randomly selected from 12 PHCs (8 urban and four rural) using multi-stage sampling method. Participants were invited to personal interview using semi-structured data collection instrument including inquiries about socio-demographics, reproductive history, previous histories of diagnosed breast lesions and breast cancer. The perceived individual barriers towards screening, their attitudes, the reasons for not attending previously held screening campaigns in Al Hassa, were also included.

Results

Low utilization of BC screening being significantly positively associated with woman's age, higher educational status, higher family income, using hormonal contraception and positive history of previous breast as shown by the results of the logistic regression model. Exploratory factor analysis showed that personal fears (especially fear of doctors/examiners, fear of hospitals and health facilities and fear of consequences/results) were the major factors that hinder women from utilizing the free of charge BC screening with high loading eigenvalue of 3.335, explaining 30.4% of the barriers.

Conclusions

Educational interventions aim at improving breast cancer knowledge and addressing barriers should be incorporated as core component of the screening program in Saudi Arabia.

Knowledge and attitude of women regarding breast cancer screening tests in Eastern Iran

Introduction

According to recent statistics, there has been a rapid growth of breast cancer in developing countries. Thus, early detection is essential. This study is based on the perception of people in the Northeast of Iran regarding breast cancer screening.

Methods

In a cross-sectional study, 1469 women were selected randomly in the period from April to November 2016. The study population consisted of women or their companions referring to outpatient clinics or people in public urban areas who filled out a breast cancer screening questionnaire in an interview.

Results

The patients’ age was in the range of 14 to 84 years (mean = 38.8). More than 84% of interviewees were not informed of breast cancer and screening tests. The main reasons mentioned by patients for their failure to do screening tests was ‘absence of any symptom or problem’ and ‘they did not think it was necessary’.

There was not a significant difference between income level, marital status and knowledge of people about breast cancer screening tests (P > 0.05). However, employment, education level and family history had a positive effect on people’s awareness of breast cancer and its screening tests (P < 0.05).

Conclusion

The lack of knowledge in people from low socio-economic classes was the main barrier to breast cancer screening. In this regard, organizing training programs by physicians and the media can help raise screening rates.

Beliefs and Behavior of Saudi Women in the University of Tabuk Toward Breast Self Examination Practice

Background: Breast cancer is one of the most frequent types of malignancy worldwide, Breast Self Exam (BSE) is considered as a simple method to screen and detect breast cancer, then early beginning of treatment and enhancing survival rates. Aim: To Identify the health beliefs about breast Self-Examination and its relationships with the frequency of BSE among the women in the University of Tabuk at Saudi Arabia. Methods: Descriptive, cross-sectional correlational design was used; Champion Health Beliefs Model (CHBM) was utilized to assess health beliefs among 400 women who answered a self-administered questionnaire. Results: Among the 400 respondents, almost all the sample (382,95.5%) heard about BSE. However, only (7.8%) practiced BSE regularly each month in the past year, and (9%) is intended to perform BSE monthly in future. There was a positive relationship between performing BSE last year and the beliefs of susceptibility and confidence. While, intention to perform BSE in the future was significantly correlated to seriousness and confidence. Perceived barriers were negatively related to BSE performance in last 12 months and in future. Conclusion: Health beliefs affect the behavior of women in practicing BSE. Confidence was related positively to BSE in past year, and future practice, while barriers belief was as the negative factor to perform BSE.

The impact of fatwas on patients' acceptance of enamel matrix derivatives for periodontal regeneration in Saudi Arabia

BACKGROUND

Since the introduction of enamel matrix derivatives (EMD) (Emdogain^®), it has not been allowed to be used in Saudi Arabia due to the religious restriction on porcine products. This study was conducted to determine the impact of the fatwas permitting the use of EMD and to assess the general perception of using bone-grafting materials in Jeddah, Saudi Arabia.

MATERIALS AND METHODS

This cross-sectional survey study included 213 patients seeking dental treatment at the Faculty of Dentistry Clinics of King Abdulaziz University, Jeddah, Saudi Arabia. They were recruited between September and November 2017. Subjects completed a questionnaire to assess their opinions before and after reading the fatwa about using EMD.

RESULTS

Majority of the study subjects (70%) did not accept the use of bone-grafting materials and EMD in periodontal regeneration before reading the fatwas. The highest rate of acceptance was observed for the use of tissues from one's own body (84%) while the biomaterials of porcine origin had the lowest acceptance rate (14.1%). Strong religious belief and low education level were the two key factors responsible for the initial refusal of EMD use before reading the fatwas. Around 45.1% of the participants changed their opinions in favor of EMD use after reading the fatwas and their interpretations. McNemar's test found a statistically significant difference in opinions collected before and after reading the fatwas (P<0.001).

CONCLUSION

A significant impact of the fatwas was found on patients' acceptance of EMD use for periodontal regeneration. We believe reliable interpretations of the fatwas may positively shift patients' attitudes toward using new biomaterials.

Perceived Barriers to Breast Cancer Screening among Saudi Women at Primary Care Setting

Background:

Screening for breast cancer (BC) is of low rate in Saudi Arabia; although it is provided in the country free of charge to the population. This cross-sectional study aimed at investigating the perceived barriers towards BC screening in Al Hassa, Saudi Arabia. It is crucial for increasing the rate of utilization of screening to identify the possible barriers for seeking BC screening in order to enhance early diagnosis and improve outcome.

Materials and Methods:

A total of 816 adult Saudi women aged ≥ 30 years attending for routine primary health services or accompanying patients at the selected primary health care centers (PHCs) were randomly selected from 12 PHCs (8 urban and four rural) using multi-stage sampling method. Participants were invited to personal interview using semi-structured data collection instrument including inquiries about socio-demographics, reproductive history, previous histories of diagnosed breast lesions and breast cancer. The perceived individual barriers towards screening, their attitudes, the reasons for not attending previously held screening campaigns in Al Hassa, were also included.

Results:

Low utilization of BC screening has being significantly associated with woman’s age (OR=2.55; 95% CI= 1.71-3.83), higher educational status (OR=2.98; 95% CI=2.05-4.34), higher family income (OR=1.96; 95% CI=1.31-2.93), using hormonal contraception (OR=1.46; 95% CI=0.99-2.13) and positive history of previous breast (OR=12.16; 95% CI=6.89-21.46), as shown by the results of the logistic regression model. Exploratory factor analysis showed that personal fears (especially fear of doctors/examiners, fear of hospitals and health facilities and fear of consequences/results) were the major factors that hinder women from utilizing the free of charge BC screening with high loading eigenvalue of 3.335, explaining 30.4% of the barriers.

Conclusion:

Educational interventions aim at improving breast cancer knowledge and addressing barriers should be incorporated as core component of the screening program in Saudi Arabia.

Cancer Incidence in Saudi Arabia: 2012 Data from the Saudi Cancer Registry

Background: In order to most appropriately allocate healthcare and research funding for cancer, it is important to have accurate population-based incidence data. The Saudi Cancer Registry (SCR) provides such information, covering the time period from 1994 to the present day. The current report concerns an overview of cancer incidence statistics for Saudi Arabia in 2012. Methods: The SCR collects data from healthcare facilities throughout the Kingdom of Saudi Arabia. All newly diagnosed cases of cancer are recorded, with information on site and histology. For the present report, age-standardised and age-specific incidence rates (ASR, AIR, respectively) were calculated, with attention to gender-specific and regional differences. Results: The total number of incident cases of cancer identified by the SCR in 2012 was 14,336, with 6,791 (47.5%) among males and 7,545 (52.6%) among females. Of this total, 11,034 cases (76.9%) occurred in patients of Saudi origin. For Saudi males, the overall ASR (inc. all cancer sites) was 78.1 per 100,000 people, while that for females was 86.7. Incidence varied by region, with the Eastern region and Riyadh displaying the highest ASRs for both males and females, and Hail and Jazan displaying the lowest. Incidence varied by gender, with colorectal cancer (13.3%), non-Hodgkin lymphoma (NHL; 8.4%), and leukaemia (8.2%) being the most common types in males, and breast (25.8%), thyroid (11.7%), and colorectal cancers (9.3%) being the most common in females. Conclusions: This analysis of cancer incidence in Saudi Arabia demonstrated significant differences according to gender, age, and region of the Kingdom. The data should help ensure the most appropriate allocation of resources, with the aim of minimising the healthcare burden associated with cancer.

Health system barriers and enablers to early access to breast cancer screening, detection, and diagnosis: a global analysis applied to the MENA region

OBJECTIVES

To identify barriers and enablers that impact access to early screening, detection, and diagnosis of breast cancer both globally and more specifically in the Middle East and North Africa (MENA) region (with a specific focus on Egypt, Jordan, Oman, Saudi Arabia, United Arab Emirates [UAE], and Kuwait) with a specific focus on the health system.

STUDY DESIGN

A systematic review of literature.

METHODS

We conducted a systematic reviewing using the PRISMA methodology. We searched PubMed, Global Index Medicus, and EMBASE for studies on 'breast cancer', 'breast neoplasm,' or 'screening, early detection, and early diagnosis' as well as key words related to the following barriers: religion, culture, health literacy, lack of knowledge/awareness/understanding, attitudes, fatalism/fear, shame/embarrassment, and physician gender from January 1, 2000 until September 1, 2016. Two independent reviewers screened both titles and abstracts. The application of inclusion and exclusion criteria yielded a final list of articles. A conceptual framework was used to guide the thematic analysis and examine health system barriers and enablers to breast cancer screening at the broader macro health system level, at the health provider level, and the individual level. The analysis was conducted globally and in the MENA region.

RESULTS

A total of 11,936 references were identified through the initial search strategy, of which 55 were included in the final thematic analysis. The results found the following barriers and enablers to access to breast cancer screening at the health system level, the health provider level, and the individual level: health system structures such as health insurance and care coordination systems, costs, time concerns, provider characteristics including gender of the provider, quality of care issues, medical concerns, and fear. In addition, the following seven barriers and enablers were identified at the health system or provider level as significantly impacting screening for breast cancer: (1) access to insurance, (2) physician recommendation, (3) physician gender, (4) provider characteristics, (5) having a regular provider, (6) fear of the system or procedure, and (7) knowledge of the health system. More specifically, the largest increased odds for having a mammogram was from having insurance, having a physician recommendation, type of provider (mainly gynecologist), and having regular contact with a physician. Clinical breast examinations were increased by having insurance and having regular contact with a physician. The eight studies identified from the MENA region identified barriers to breast cancer screening related to service quality, fear of pain and of cancer itself, female versus male provider, having a physician recommend the screen, cost issues as well as time and convenience of the services.

CONCLUSIONS

There are a number of system changes that can be made to remove barriers to breast cancer screening. Some of these system changes apply directly to MENA countries. A larger health system assessment of a country is warranted to determine which health system changes should be made to most efficiently and effectively improve access to breast cancer screening.

Sociocultural Influences on Arab Women's Participation in Breast Cancer Screening in Qatar

Breast cancer, the most common cancer among Arab women in Qatar, significantly affects the morbidity and mortality of Arab women largely because of low participation rates in breast cancer screening. We used a critical ethnographic approach to uncover and describe factors that influence Arab women's breast cancer screening practices. We conducted semistructured interviews with 15 health care practitioners in Qatar. Through thematic analysis of the data, we found three major factors influencing breast cancer screening practices: (a) beliefs, attitudes, and practices regarding women's bodies, health, and illness; (b) religious beliefs and a culturally sensitive health care structure; and (c) culturally specific gender relations and roles. Arab women's health practices cannot be understood in isolation from the sociocultural environment. The problem of low rates of breast cancer screening practices and supportive interventions must be addressed within the context and not be limited to the individual.

Financial hardship on the path to Universal Health Coverage in the Gulf States

BACKGROUND

Countries globally are pursuing universal health coverage to ensure better healthcare for their populations and prevent households from catastrophic expenditure. The countries of the Gulf Cooperation Council (GCC) have and continue to implement reforms to strengthen their health systems. A common theme between the countries is their pursuit of universal health coverage to provide access to necessary health care without exposing people to financial hardship.

METHODS

Using nationally representative data from the Global Findex study, we sought to analyze the hardship faced by individuals from four high-income countries in the GCC. We estimated the weighted proportion of individuals borrowing for medical reasons and those who are not able to obtain emergency funds. We further examined variations in these outcomes by key socioeconomic factors.

RESULTS

We found up to 11% of respondents borrowed money for medical purposes, double of that reported in other high-income countries. In contrast to affluent respondents, we found that respondents from deprived background were more likely to borrow money for medical purposes (adjusted odds ratio: 1.81, P<0.001) and expected to fail in obtaining emergency funds (adjusted odds ratio: 4.03, P<0.001).

CONCLUSION

In moving forward with their reforms, GCC countries should adopt a financing strategy that addresses the health needs of poorer groups in their pursuit of universal health coverage.

Should low-income countries invest in breast cancer screening?

With the increase in incidence and mortality of breast cancer in low-income countries (LICs), the question of whether LICs should promote breast cancer screening for early detection has gained tremendous importance. Because LICs have limited financial resources, the value of screening must be carefully considered before integrating screening programs into national healthcare system. Mammography-the most commonly used screening tool in developed countries-reduces breast cancer-specific mortality among women of age group 50-69, but the evidence is not so clear for younger women. Further, it does not reduce the overall mortality. Because the women in LICs tend to get breast cancer at younger age and are faced with various competing causes of mortality, LICs need to seriously evaluate whether mammographic screening presents a good value for the investment. Instead, we suggest a special module of clinical breast examination that could provide similar benefits at a very low cost. Nevertheless, we believe that LICs would obtain a much greater value for their investment if they promote primary prevention by tobacco cessation, healthier food and healthier lifestyle campaigns instead.

microRNA expression profiling on individual breast cancer patients identifies novel panel of circulating microRNA for early detection

Breast cancer (BC) is the most common cancer type and the second cause of cancer-related death among women. Therefore, better understanding of breast cancer tumor biology and the identification of novel biomarkers is essential for the early diagnosis and for better disease stratification and management choices. Herein we developed a novel approach which relies on the isolation of circulating microRNAs through an enrichment step using speed-vacuum concentration which resulted in 5-fold increase in microRNA abundance. Global miRNA microarray expression profiling performed on individual samples from 23 BC and 9 normals identified 18 up-regulated miRNAs in BC patients (p(corr) < 0.05). Nine miRNAs (hsa-miR-4270, hsa-miR-1225-5p, hsa-miR-188-5p, hsa-miR-1202, hsa-miR-4281, hsa-miR-1207-5p, hsa-miR-642b-3p, hsa-miR-1290, and hsa-miR-3141) were subsequently validated using qRT-PCR in a cohort of 46 BC and 14 controls. The expression of those microRNAs was overall higher in patients with stage I, II, and III, compared to stage IV, with potential utilization for early detection. The expression of this microRNA panel was slightly higher in the HER2 and TN compared to patients with luminal subtype. Therefore, we developed a novel approach which led to the identification of a novel microRNA panel which was upregulated in BC patients with potential utilization in disease diagnosis and stratification.

Current Status and Future Projections of Breast Cancer in Asia

Asia is the world's largest continent comprising about 3/5 of the human population. Breast cancer is the most common type of cancer and the second leading cause of cancer-related deaths among women in Asia, accounting for 39% of all breast cancers diagnosed worldwide. The incidence of breast cancer in Asia varies widely across the continent and is still lower than in Western countries, but the proportional contribution of Asia to the global breast cancer rates is increasing rapidly in parallel to the socioeconomic development. However, the mortality-to-incidence ratios are much higher for Asia than for Western countries. Most Asian countries are low- and middle-income countries (LMICs) where breast cancer presents at a younger age and a later stage, and where patients are more likely to die from the disease than those in Western countries. Moreover, diagnostic workup, treatment and palliative services are inadequate in most Asian LMICs. In this review, we present an overview of the breast cancer risk factors and epidemiology, control measures, and cancer care among Asian countries.

Using the health belief model to predict breast self examination among Saudi women

Background

In the Kingdom of Saudi Arabia, breast cancer (BC) usually presents at advanced stages and more frequently in young pre-menopausal women in comparison to western countries. There is controversy surrounding the efficacy of breast self examination (BSE) for early detection of BC in countries where other methods are available. This study aims to explore the perception towards breast cancer and towards BSE among Saudi women, using the Health Belief Model (HBM).

Methods

A convenient sample of adult Saudi female employees, working at King Abdulaziz Medical City, Riyadh, Saudi Arabia (n = 225), and their non-working adult female family members (n = 208), were subjected to the Arabic version of revised Champion’s Health Belief Model Scale (CHBMS) and the Arabic version of Breast Cancer Awareness Measure (CAM), to assess their knowledge and attitude on BC respectively. Percentage mean score (PMS) for each HBM domain was calculated. Significant predictors of BSE practice were identified using logistic regression analysis and significance was considered at p < 0.05.

Results

The majority of women heard about BSE (91.2 %), only 41.6 % reported ever practicing BSE and 21 % performed it regularly. Reported reasons for not doing BSE were: not knowing how to examine their breast (54.9 %), or untrusting themselves able to do it (24.5 %). Women were less knowledgeable about BC in general, its risk factors, warning signs, nature and screening measures (PMS:54.2 %, 44.5 %, 61.4 %, 53.2 %, 57.6 % respectively). They reported low scores of; perceived susceptibility, seriousness, confidence and barriers (PMS: 44.8 %, 55.6 %, 56.5 % & 41.7 % respectively), and high scores of perceived benefits and motivation (PMS: 73 % & 73.2 % respectively) to perform BSE. Significant predictors of  BSE performance were: levels of perceived barriers (p = 0.046) and perceived confidence (p = 0.001) to BSE, overall knowledge on BC (p < 0.001), work status (p = 0.032) and family history of BC (p = 0.011).

Conclusions

Saudi women had poor knowledge on BC, reported negative attitude towards BSE and their practice was poor. Working women and those with family history of BC, higher perceived confidence and lower perceived barriers on HBM, and those with high level of knowledge on BC were more likely to perform BSE. Breast awareness as an alternative to BSE needs further investigations. HBM was shown as a valid tool to predict BSE practice among Saudi women.

Medication use for chronic health conditions among adults in Saudi Arabia: findings from a national household survey

PURPOSE

Chronic diseases and their risk factors are believed to be common in the Kingdom of Saudi Arabia (KSA). Most of them require long-term management through medications. We examined patterns of medication use for chronic health conditions (CHC) in KSA based on a national survey.

METHODS

The Saudi Health Interview Survey was a cross-sectional nationally representative household survey of 10,735 individuals aged 15 years or older in 2013. The survey consisted of a detailed health questionnaire. Current medications for CHC were assessed and classified based on the Anatomical Therapeutic Chemical classification.

RESULTS

Among the respondents, 11.8% (standard error = 0.4) reported taking at least one medication for CHC with a mean number of 2.05 (standard error = 0.05) medication items. In addition to older age (odds ratio = 1.94 per each decade, 95%CI: 1.83-2.05) and male gender (odds ratio = 1.22, 95%CI: 1.06-1.41), those with higher income were more likely to take medication. The most common medicines were drugs used for diabetes (A10 Anatomical Therapeutic Chemical code). The top 20 drugs accounted for about 80% of all medications. Only 32.7% of medications were reported to be used exactly as prescribed.

CONCLUSIONS

Compared with the prevalence of CHC in KSA, our study indicates a potential underuse of medications as well as non-adherence to the directions for use. Interventions such as improved clinical guidelines for healthcare providers to increase utilization of necessary medication and educational programs to improve patients' adherence are needed.

Access and barriers to healthcare in the Kingdom of Saudi Arabia, 2013: findings from a national multistage survey

OBJECTIVES

We analysed data from a large household survey to identify barriers to healthcare in the Kingdom of Saudi Arabia.

METHODS

The Saudi Health Interview Survey (SHIS) is a national multistage survey of individuals aged 15 years or older. The survey combined a household questionnaire and a laboratory blood analysis. We used a backward elimination multivariate logistic regression model to measure association between (1) diagnosis, (2) treatment, and (3) control of hypertension or diabetes and sociodemographic factors, history of diagnosis with chronic conditions, and type of, and distance travelled to, the clinic last visited.

RESULTS

Between April and June 2013, a total of 10,735 participants completed SHIS and were invited to the local health clinics. Among hypertensive individuals, women, older individuals, and those previously diagnosed with diabetes and hypercholesterolaemia were more likely to have been diagnosed with hypertension than their counterparts. Among participants diagnosed with hypertension, the likelihood of being treated increased with age and education. The likelihood of having uncontrolled blood pressure despite treatment increased with education and a history of diagnosis with hypercholesterolaemia. Type of clinic visited and distance travelled to last clinic visit were not associated with diagnosis or treatment of hypertension or control of blood pressure. Similar factors were associated with the likelihood of diagnosis and treatment among individuals with diabetes. Having uncontrolled glycated haemoglobin levels, despite treatment, was less common among those who visited governmental clinics other than those of the Ministry of Health, compared with those who visited Ministry clinics.

CONCLUSIONS

Our findings highlight the importance of individual characteristics in healthcare-seeking practices rather than system-based potential barriers. Saudis seem to mostly seek healthcare when sick. Hence, the Saudi Ministry of Health needs to implement a comprehensive plan including health education and investigations, to understand the barriers and bottlenecks to healthcare-seeking behaviour.

Correction: breast cancer screening in Saudi Arabia: free but almost no takers

[This corrects the article DOI: 10.1371/journal.pone.0119051.].
