    BACKGROUND: Evidence to guide policymakers in developing affordable and equitable cancer control plans are scarce in low- and middle-income countries (LMIC).

    METHODS: The 2012-2014 ASEAN Costs in Oncology Study prospectively followed-up 9513 newly diagnosed cancer patients from eight LMIC in Southeast Asia for 12 months. Overall and country-specific incidence of financial catastrophe (out-of-pocket health costs ≥ 30% of annual household income), economic hardship (inability to make necessary household payments), poverty (living below national poverty line), and all-cause mortality were determined. Stepwise multinomial regression was used to estimate the extent to which health insurance, cancer stage and treatment explained these outcomes.

    RESULTS: The one-year incidence of mortality (12% in Malaysia to 45% in Myanmar) and financial catastrophe (24% in Thailand to 68% in Vietnam) were high. Economic hardship was reported by a third of families, including inability to pay for medicines (45%), mortgages (18%) and utilities (12%), with 28% taking personal loans, and 20% selling assets (not mutually exclusive). Out of households that initially reported incomes above the national poverty levels, 4·9% were pushed into poverty at one year. The adverse economic outcomes in this study were mainly attributed to medical costs for inpatient/outpatient care, and purchase of drugs and medical supplies. In all the countries, cancer stage largely explained the risk of adverse outcomes. Stage-stratified analysis however showed that low-income patients remained vulnerable to adverse outcomes even when diagnosed with earlier cancer stages.

    CONCLUSION: The LMIC need to realign their focus on early detection of cancer and provision of affordable cancer care, while ensuring adequate financial risk protection, particularly for the poor.

    In Malaysia, breast cancer is the commonest cancer among women indicating that early diagnosis and screening practice is important to increase the survival rate. Breast self-examination (BSE), clinical breast examination (CBE) and mammography are the main screening practices for breast cancer. Knowledge and awareness of breast cancer can play an important role in aiding early detection of breast cancer. Little is known about the knowledge of breast cancer and screening practices among the non-academic staff in IIUM, Kuantan. As such this study aims to determine the knowledge and screening practices of breast cancer amongst the non-academic staff at the International Islamic University Malaysia (IIUM), Kuantan Campus. A cross-sectional study was conducted on 100 nonacademic staff from ten different departments in IIUM, Kuantan from March to April 2017. Data were collected using a self-administered questionnaire on knowledge of breast cancer and screening practices. The relationship between socio-demographic characteristics and knowledge of breast cancer and breast cancer screening practices were carried out using chi-square. No significance difference was found between knowledge of breast cancer and socio-demographic factors. However significant relationships were found between the age of respondents and BSE as well as the level of education of respondents and CBE. Most non-academic staff possessed an average level of knowledge on breast cancer and screening practices due to possibly ease of access to information. Low performance of breast screening practices was indicated possibly due to lack of awareness, misconception of the need and benefits derived from such screening practices.

    OBJECTIVES: Fingerprints have so far been used for determining the basis of certain malignant diseases, with positive outcomes. Considering the high rates of cancer-related mortality in Iran, this study was conducted for the purpose of examining the dermatoglyphic pattern of fingers in patients with gynecological cancers as compared to healthy people.

    STUDY DESIGN: The present study was conducted on 151 women with gynecological cancers as the case group and 152 healthy women with no history of such cancers as control group. The dematographic details of participants from both control and case groups were collected using a checklist, and the pattern of their fingerprints was prepared and examined. The data were analyzed for their significance using chi-square test and t- test. Odds ratio with 95% confidence intervals were calculated.

    RESULTS: Dermatoglyphic analysis showed that arch and loop patterns significantly changed in cases group as compared to control. However, the odds ratio suggested that loop pattern in 6 or more fingers might be a risk factor for developing gynecological cancers.

    CONCLUSION: Our results showed that there is an association between fingerprint patterns and gynecological cancers and so, dermatoglyphic analysis may aid in the early diagnosis of these cancers.

    Head and neck squamous cell carcinoma (HNSCC) represents a significant world health problem, with approximately 600,000 new cases being diagnosed annually. The prognosis for patients with HNSCC is poor and, therefore, the identification of biomarkers for screening, diagnosis and prognostication would be clinically beneficial. A limited number of studies have used lipidomics to profile lipid species in the plasma of cancer patients. However, the profile and levels of lysophosphatidic acid (LPA) species have not been examined in HNSCC. In this study, a targeted lipidomics approach using liquid chromatography triple quadrupole mass spectrometry (LCMS/MS) was used to analyse the concentration of LPA (16:0 LPA, 18:0 LPA, 18:1 LPA, 18:2 LPA and 20:4 LPA) in the plasma of patients with oral squamous cell carcinoma (OSCC) and nasopharyngeal carcinoma (NPC), together with healthy controls. The levels of three LPA species (18:1 LPA, 18:2 LPA and 20:4 LPA) were significantly lower in the plasma of OSCC patients, whilst the concentrations of all five LPA species tested were significantly lower in plasma from NPC patients. Furthermore, the order of abundance of LPA species in plasma was different between the control and cancer groups, with 16:0 LPA, 18:0 LPA levels being more abundant in OSCC and NPC patients. Medium to strong correlations were observed using all pairs of LPA species and a clear separation of the normal and tumour groups was observed using PCA analysis. In summary, the results of this study showed that the levels of several LPA species in the plasma of patients with OSCC and NPC were lower than those from healthy individuals. Understanding these variations may provide novel insights into the role of LPA in these cancers.

    OBJECTIVE: To compare the effectiveness of different methods of recall for repeat Pap smear among women who had normal smears in the previous screening.
    DESIGN: Prospective randomized controlled study.
    SETTING: All community clinics in Klang under the Ministry of Health Malaysia.
    PARTICIPANTS: Women of Klang who attended cervical screening and had a normal Pap smear in the previous year, and were due for a repeat smear were recruited and randomly assigned to four different methods of recall for repeat smear.
    INTERVENTION: The recall methods given to the women to remind them for a repeat smear were either by postal letter, registered letter, short message by phone (SMS) or phone call.
    MAIN OUTCOME MEASURES: Number and percentage of women who responded to the recall within 8 weeks after they had received the recall, irrespective whether they had Pap test conducted. Also the numbers of women in each recall method that came for repeat Pap smear.
    RESULTS: The rates of recall messages reaching the women when using letter, registered letter, SMS and phone calls were 79%, 87%, 66% and 68%, respectively. However, the positive responses to recall by letter, registered letter, phone messages and telephone call were 23.9%, 23.0%, 32.9% and 50.9%, respectively (p<0.05). Furthermore, more women who received recall by phone call had been screened (p<0.05) compared to those who received recall by postal letter (OR=2.38, CI=1.56-3.62).
    CONCLUSION: Both the usual way of sending letters and registered letters had higher chances of reaching patients compared to using phone either for sending messages or calling. The response to the recall method and uptake of repeat smear, however, were highest via phone call, indicating the importance of direct communication.

    BACKGROUND: Cervical cancer is the second most common cancer among Malaysian women with an ASR of 17.9 and a mortality rate of 5.6 per 100,000 population in 2008 (GLOBOCAN, 2008). The 5 year prevalence was estimated to be 14.5 per 100,000 population. As the second most common cancer affecting productive females, cervical cancer imposes an impact to the socioeconomic aspect of the country. However, the poor uptake of cervical cancer screening is a major problem in detecting early pre-cancerous lesions and thus, delay in initiating treatment for cervical cancer. Realizing the urgency to increase the uptake of PAP smear, besides enhancing the promotion of PAP smear screening for women above 35 years old, the call-recall system for pap smear screening had been piloted in one of the suburban districts which aimed to improve regular participation of women for cervical and breast cancer screening. This is of public health importance as identifying the best feasible option to increase patient's respond to participate in the screening program effectively in our setting will be helpful in implementing an organized regular population based screening program tailored to our setting. The pilot program of cervical cancer screening in Klang was an opportunity to assess different options in recalling patients for a repeat pap smear to increase their participation and adherence to the program.

    METHODS AND RESULTS: This was a population based randomized control trial. Women aged 20-65 years in the population that matched the inclusion and exclusion criteria were re-called for a repeat smear. There are four different intervention groups; letter, registered letters, short messages services (SMS) and phone calls where 250 subjects were recruited into each group. Samples were generated randomly from the same population in Klang into four different groups. The first group received a recall letter for a repeat smear similar to the one that has been given during the first invitation. The intervention groups were either be given a registered letter, an SMS or a phone call to re-call them. The socio-demographic data of the patients who came for uptake were collected for further analysis. All the groups were followed up after 8 weeks to assess their compliance to the recall.

    CONCLUSIONS: The study will provide recommendations about the most effective methods for recall in a population based pap smear screening program on two outcomes: i) patients response; ii) uptake for repeat pap smear.

    Despite global progress in research, improved screening and refined treatment strategies, colorectal cancer (CRC) remains as the third most common malignancy. As each type of cancer is different and exhibits unique alteration patterns, identifying and characterizing gene alterations in CRC that may serve as biomarkers might help to improve diagnosis, prognosis and predict potential response to therapy. With the emergence of next generation sequencing technologies (NGS), it is now possible to extensively and rapidly identify the gene profile of individual tumors. In this study, we aimed to identify actionable somatic alterations in Dukes' B and C in CRC via NGS. Targeted sequencing of 409 cancer-related genes using the Ion Ampliseq(TM) Comprehensive Cancer Panel was performed on genomic DNA obtained from paired fresh frozen tissues, cancer and normal, of Dukes' B (n = 10) and Dukes' C (n = 9) CRC. The sequencing results were analyzed using Torrent Suite, annotated using ANNOVAR and validated using Sanger sequencing. A total of 141 somatic non-synonymous sequence variations were identified in 86 genes. Among these, 64 variants (45%) were predicted to be deleterious, 38 variants (27%) possibly deleterious while the other 39 variants (28%) have low or neutral protein impact. Seventeen genes have alterations with frequencies of ≥10% in the patient cohort and with 14 overlapped genes in both Dukes' B and C. The adenomatous polyposis coli gene (APC) was the most frequently altered gene in both groups (n = 6 in Dukes' B and C). In addition, TP53 was more frequently altered in Dukes' C (n = 7) compared to Dukes' B (n = 4). Ten variants in APC, namely p.R283(∗), p.N778fs, p.R805(∗), p.Y935fs, p.E941fs, p.E1057(∗), p.I1401fs, p.Q1378(∗), p.E1379(∗), and p.A1485fs were predicted to be driver variants. APC remains as the most frequently altered gene in the intermediate stages of CRC. Wnt signaling pathway is the major affected pathway followed by P53, RAS, TGF-β, and PI3K signaling. We reported the alteration profiles in each of the patient which has the potential to affect the clinical decision. We believe that this study will add further to the understanding of CRC molecular landscape.

    BACKGROUND: There has been a rapid increase in colorectal cancer (CRC) cases in Asian countries, including Malaysia. CRC is usually diagnosed at a late stage, and early detection of CRC is vital in improving survival. This study was conducted to determine the uptake rate of the immunochemical faecal occult blood test (iFOBT), the response rate to colonoscopy, and the CRC detection rate. We also wanted to identify the association between colorectal neoplasia and the Asia Pacific Colorectal Cancer Screening (APCS) scoring system.

    METHODS: We recruited 2264 individuals from The Malaysian Cohort participants aged 35-65 years who consented to colorectal screening using the iFOBT kit from July 2017 until January 2019.

    RESULTS: The response rate and positive iFOBT test rate of this study were 79.6% and 13.1% respectively. Among those with positive results, 125 individuals (52.7%) underwent colonoscopy; CRC was detected in six of them while 45 others (36.0%) had polyps. The overall CRC detection rate was 0.3% while the colorectal neoplasia detection rate (both colorectal cancer and colorectal polyps) was 2.3%. The APCS scoring indicated a significant association with colorectal neoplasia risk, with increasing trend by severity from moderate to high risk (3.46-11.14) compared to low risk. Most of the participants who were positive for iFOBT were those at high risk.

    CONCLUSIONS: The awareness of CRC risk and iFOBT screening are important strategies for early detection of CRC. We showed a CRC detection rate of 0.3 % among those who volunteered to have the iFOBT screening.

    BACKGROUND: Breast cancer is the most common cancer among women in Malaysia. Of the total cancer cases registered in the National Cancer Registry for 2006, 3,525 were female breast cancer cases. The overall age standardized rate was 39.3 per 100,000 population in 2006. An estimated 30%-40% were diagnosed in the late stages and this had resulted in poor survival rates. The purpose of the study was to determine the factors and barriers related to mammography screening uptake among hospital personnel.

    METHODS: This mixed method explanatory study was carried out on a universal sampling of 707 female personnel aged 40 and above, from June 2007 until November 2007. The study was conducted at University Malaya Medical Centre, a tertiary hospital in Kuala Lumpur. Pre-tested self-administered questionnaires were mailed to eligible personnel.

    RESULTS: The prevalence of mammography screening uptake was 80.3% (95%CI: 76.8%,83.5%) among 534 respondents. Personnel who had physician recommendation had significantly higher odds of mammography screening uptake compared to those who did not have recommendation, adjusted odds ratio of 21.25 (95%CI:12.71,36.56). Reported barriers can be grouped into several themes; negative perception of the procedure like embarrassment due to the presence of male technicians/radiographers; low confidence with radiologist/radiographers in detecting abnormality; lack of coping skills in dealing with expected results and pain during procedure.

    CONCLUSIONS: The findings of this study highlighted that 20% of personnel did not undertake mammography screening although there is no cost incurred and the procedure is fully accessible to them. Opportunistic recommendation by physician and concerns on the procedure should be addressed.

    ABSTRACTS FOR INTERNATIONAL FAMILY HEALTH CONFERENCE 2019 (I-FaH 2019)
    Introduction: As cervical cancer is the third most common cancer among women and ten percent of cervical cancer incidence among those 65 years and above, Pap smear is still relevant to be performed among older women. The aim of this study was to determine the determinants of Pap smear screening among older women in an urban setting.
    Methods: This cross-sectional study was conducted among 515 women aged 50 and above in two urban health centres in Gombak, Selangor. The sampling technique conducted was random systematic sampling. The indepen-dent variables were age, marital status, employment status, gynaecological history (family history of cervical cancer, menopause, hysterectomy), obstetric history (number of live births, ever had contraception), presence of chronic diseases (hypertension, Diabetes Mellitus, heart disease). Results: Only 202 (39.2%) out of 515 undergone Pap smear screening. An estimated 80.7% of them had their last Pap smear a year ago. The mean age of the respondents was 58.83± 7.05 years old and 77.3% had one and more comorbidities. The respondents preferred health care person-nel as the source for the pap smear information compared to reading materials and internet. Married vs divorced (aOR=1.89,p=0.02); those with heart disease (aOR=0.32,p value=0.01; those with Diabetes Mellitus (aOR=0.57,p value=0.01; those who had hysterectomy (OR=2.89, p value=0.04) and those who had contraception (aOR=3.72, p value =

    OBJECTIVES: The objectives of this study were to determine the prevalence and predictors of Pap smear screening among women aged 50 years and older.
    STUDY DESIGN: This cross-sectional study was conducted at two large urban health centres in Selangor. A total of 515 women aged 50 and older were recruited.
    RESULTS: The mean age of the respondents was 58.83±7.05, with a range of 50- 83 years. The prevalence of Pap smear screening was 39.22% (n=202). From the multivariate analysis, Pap smear screening was significantly associated with health care provider advice (adjusted odds ratio (AOR)=18.75; 95% CI=8.30, 42.37); tertiary (AOR=11.26; 95% CI=1.50, 84.68) and secondary education level (AOR=9.47; 95% CI=1.43, 62.84); use of contraception (AOR=2.90; 95% CI=1.48, 5.69); heart disease (AOR=0.22; 95% CI=0.05, 0.97); and worry about Pap smear results (AOR=0.20; 95% CI=0.09, 0.42).
    CONCLUSION: The prevalence of Pap smear screening in the older women is unsatisfactory. Health care provider advice, education level, use of contraception, heart disease and worry about Pap smear results were predictors of undergoing Pap smear screening in this study population.

    This study aims to determine the acceptability of Human Papilloma Virus (HPV) self-sampling and the factors associated with willingness to buy HPV self-sampling kit in the future. A total of 164 women aged 28-60 years old from Obstetrics & Gynaecology clinics at a teaching hospital performed HPV self-sampling using the Digene HC2 DNA collection kit. After samples were taken, the participants were given self-administered questionnaires. The majority of the participants were Malay (93.9%), had attained tertiary education (65.2%) and were employed (70.1%). The acceptability was good. More than half of the participants felt that self-sampling was easy. Only 1.2% felt that the procedure was difficult to perform. Most reported no pain at all during the procedure (66.9%). The commonest concern was getting a good sample (90.1%). A number of Pap smears were found to be significantly associated with the willingness to buy the HPV self-sampling kit. HPV self-sampling has the potential to be included in the cervical cancer screening programme. Impact Statement What is already known on this subject: HPV self-sampling is acceptable in some developed and developing countries. It is acceptable because it was easy to perform with very minimal pain or discomfort. Studies on the acceptance of self-screening are needed to plan a policy on self-sampling in the future. What the results of this study add: Our study adds new findings to the body of knowledge on self-sampling in the local population. We found that more women are willing to do the self-sampling at the clinic rather than at home. Although more than 90% expressed willingness to do self-sampling in the future, only 70% of them were willing to purchase the kit. Cost is a potential barrier to women who have the interest to perform the self-sampling. Given the global economic challenges, cost is inevitably an important predictor that we have to consider. What the implications are of these findings for clinical practice and/or further research: Future research should examine women from the rural areas and those who are resilient to Pap smear screening. In clinical practice, clinicians should acknowledge that cost is a potential barrier for women who are willing to do self-sampling. Self-sampling could be an option for women with no financial constraint to buy the kit. However, clinicians should counsel women so that they can make an informed choice in determining their screening method.

    BACKGROUND: A colorectal cancer screening program was piloted in two districts of Kedah in 2013. There is scarcity of information on colorectal cancer screening in Malaysia.

    OBJECTIVE: Thus, this research was conducted to evaluate the colorectal cancer screening program in the districts to provide insights intop its efficacy.

    MATERIALS AND METHODS: A cross sectional study was conducted using data on the colorectal cancer screening program in 2013 involving Kota Setar and Kuala Muda districts in Malaysia. We determined the response rate of immunochemical fecal occult blood test (iFOBT), colonoscopy compliance, and detection rates of neoplasia and carcinoma. We also compared the response of FOBT by demographic background.

    RESULTS: The response rate of FOBT for first iFOBT screening was 94.7% while the second iFOBT screening was 90.7%. Participants from Kuala Muda district were 27 times more likely to default while Indians had a 3 times higher risk of default compared to Malays. The colonoscopy compliance was suboptimal among those with positive iFOBT. The most common finding from colonoscopy was hemorrhoids, followed by tubular adenoma. Detection rate of carcinoma and neoplasia for our program was 1.2%.

    CONCLUSIONS: In summary, the response rate of iFOBT was encouraging but the colonoscopy compliance was suboptimal which led to a considerably low detection rate.

    Background: Cervical cancer screening reduced cancer morbidity and mortality in developed countries. Health education interventions are expected to enhance screening and early detection. Thus, this review is aimed to see the effectiveness of the interventions in cervical cancer screening uptake.

    Methods: Online databases (PubMed/MEDLINE/PubMed Central, EMBASE, Cochrane Central Register of Controlled Trials, Web of Science and Google Scholar) were searched for all published eligible research articles in the past 12 years (as of January 2005-2017). A total of 17 research articles were included. The interventions were classified as 'individual level', 'community level' and 'cultural sensitive educations' which contains various interventions in their content as compared with usual care. A quality coding system was assessed using Cochrane checklists and rated by each researcher independently and the average score was given accordingly. This study was registered in PROSPERO 2017: CRD42017060405.

    Results: The review dovetailed 17 studies. Ten studies (58.82%) were conducted in the United States, three in Iran (17.65%) and one each in Malaysia, China, Cameroon and Nigeria (23.53%). Almost all levels of the interventions boosted the screening uptake and the Pap test. However, the individual level health education interventions were prioritized in many of the studies.

    Conclusion: The review indicated that health education interventions have immense contributions in boosting the screening uptake. However, the effectiveness varies with study setting, populations and the way of delivery. Therefore, the limited quality of the studies indicated that further research is required to develop a simple and effective intervention to boost cervical cancer screening uptake.

    BACKGROUND: Although breast cancer is a major public health worry among Asian women, adherence to screening for the disease remains an obstacle to its prevention. A variety of psycho-social and cultural factors predispose women to delay or avoidance of screening for breast cancer symptoms at the early stages when cure is most likely to be successful. Yet few interventions implemented to date to address this condition in this region have drawn on health behavior theory.

    MATERIALS AND METHODS: This paper reviews the existing literature on several cognitive theories and models associated with breast cancer screening, with an emphasis on the work that has been done in relation to Asian women. To conduct this review, a number of electronic databases were searched with context-appropriate inclusion criteria.

    RESULTS: Little empirical work was found that specifically addressed the applicability of health theories in promoting adherence to the current breast cancer prevention programs Among Asian women. However, a few studies were found that addressed individual cognitive factors that are likely to encourage women's motivation to protect themselves against breast cancer in this region of the world. The findings suggest that multi-level, socio-cultural interventions that focus on cognitive factors have much promise with this issue.

    CONCLUSIONS: Interventions are needed that effectively and efficiently target the personal motivation of at-risk Asian women to seek out and engage in breast cancer prevention. Concerning implications, personal motivation to seek out and engage in individual preventive actions for breast cancer prevention among Asian women is a timely, high priority target with practical implications for community development and health promotion. Further studies using qualitative, anthropologic approaches shaped for implementation in multi-ethnic Asian settings are needed to inform and guide these interventions.

    Mammography utilization is low in Iran compared with other countries. Here a cross-sectional survey design was used to investigate psycho-social and individual factors associated with mammography among 400 women asymptomatic of breast cancer. The study was carried out at the four outpatient clinics of Tehran during the period from July through October, 2009. We found that mammography screening was related to higher self-efficacy and women's occupation. Future tailored interventions on potential psycho-social determinants and specific demographic factors are critical in increasing mammography screening rates among Iranian women.

    BACKGROUND: Early detection is a critical part of reducing the burden of breast cancer and breast selfexamination (BSE) has been found to be an especially important early detection strategy in low and middle income countries such as Malaysia. Although reports indicate that Malaysian women report an increase in BSE activity in recent years, additional research is needed to explore factors that may help to increase this behavior among Southeastern Asian women.

    OBJECTIVE: This study is the first of its kind to explore how the predicting variables of self-efficacy, perceived barriers, and body image factors correlate with self-reports of past BSE, and intention to conduct future breast self-exams among female students in Malaysia.

    MATERIALS AND METHODS: Through the analysis of data collected from a prior study of female students from nine Malaysian universities (n=842), this study found that self-efficacy, perceived barriers and specific body image sub-constructs (MBSRQ-Appearance Scales) were correlated with, and at times predicted, both the likelihood of past BSE and the intention to conduct breast self-exams in the future.

    RESULTS: Self-efficacy (SE) positively predicted the likelihood of past self-exam behavior, and intention to conduct future breast self-exams. Perceived barriers (BR) negatively predicted past behavior and future intention of breast self-exams. The body image sub-constructs of appearance evaluation (AE) and overweight preoccupation (OWP) predicted the likelihood of past behavior but did not predict intention for future behavior. Appearance orientation (AO) had a somewhat opposite effect: AO did not correlate with or predict past behavior but did correlate with intention to conduct breast self-exams in the future. The body image sub-constructs of body area satisfaction (BASS) and self-classified weight (SCW) showed no correlation with the subjects' past breast self-exam behavior nor with their intention to conduct breast self-exams in the future.

    CONCLUSIONS: Findings from this study indicate that both self-efficacy and perceived barriers to BSE are significant psychosocial factors that influence BSE behavior. These results suggest that health promotion interventions that help enhance self-efficacy and reduce perceived barriers have the potential to increase the intentions of Malaysian women to perform breast self-exams, which can promote early detection of breast cancers. Future research should evaluate targeted communication interventions for addressing self-efficacy and perceived barriers to breast self-exams with at-risk Malaysian women. and further explore the relationship between BSE and body image.

    The mean glandular dose (MGD) is a measurement used in mammography to assess the amount of radiation absorbed. By considering specific exposure radiation dose criteria, MGD ensures minimal radiation while maintaining image quality for detecting abnormalities. The relationship between MGD and compressed breast thickness (CBT) is commonly utilized in mammographic dose surveys. This study aims to estimate the MGD-CBT relationship based on patient age in Jordan through retrospective analysis. The analysis involved 3465 screening mammography images of women aged 40-80, divided into three age groups: 40-49, 50-64 and 65-80 years. Each group had a specific CBT range (16.5-156 mm). The results indicate that MGD ranges from 1.6 to 1.7 mGy across all three age groups, independent of CBT. Thus, a significant and positive correlation exists between MGD and CBT in all age groups.

    INTRODUCTION: This review aimed to summarise the trend of mammogram screening uptake published in local studies between years 2006 and 2015 among the Malaysian women aged 40 years and above, and identify the associated factors and barriers, as well as discuss limitations of the studies and research gaps.

    METHODS: A systematic review was conducted on breast cancer screening studies among Malaysian women, published between January 2006 and December 2015. Online databases were searched using keywords: "mammogram", "mammography", "uptake", "breast cancer screening" and "Malaysia".

    RESULTS: Thirteen original articles were reviewed. The rate of mammography uptake ranged between 3.6% and 30.9% among the general population, and 80.3% among personnel of a tertiary hospital. Factors associated with mammogram screening were clinical breast examination, age, income, knowledge on breast cancer and mammogram, perceived susceptibility to breast cancer, ethnicity and education level. Barriers to mammogram screening were lack of knowledge, embarrassment, fear of cancer diagnosis, perception that breast screening was unnecessary, lack of coping skills and pain during procedure. However, almost all of the studies could not be generalised beyond the study sample because of the limited number of sites and respondents; and most data were self-reported with no objective measures of the responses.

    CONCLUSION: Mammogram screening uptake among women in selected communities were generally low. Further studies involving the general population are essential. Future studies should also explore the availability, affordability and accessibility of this service especially in the pursuit of achieving universal health coverage in breast cancer management.
