OBJECTIVE: To investigate the associations between breast cancer staging and body mass index (BMI), menopausal status, and family history of breast cancer, as well as to assess the expression of tumor markers in women with breast cancer in Brunei Darussalam. METHODS: A retrospective cross-sectional study was carried out at The Brunei Cancer Centre. Cases of women with breast cancer between 2000 and 2013 were retrieved from the medical records section and entered into a clinical proforma. These were reviewed and analyzed using appropriate statistical methods. RESULTS: Overall, the mean age at diagnosis was 53.6 years ± 9.83. The postmenopausal women had a significantly higher risk of being diagnosed with late-onset breast cancer than premenopausal women (P = 0.022). The expressions of PR (P = 0.034), Her2 (P = 0.046), and CatD (P = 0.004) were significantly different in breast cancer staging. Other factors did not have a statistically-significant association with breast cancer staging. CONCLUSION: While most of the factors studied were not significantly different in breast cancer staging, our findings showed that it is recommended that high-risk women perform regular breast screening after the age of 40 years old. A future study highly appreciates comparing breast cancer risk factors among the Bruneian and Western populations.
The world has been experiencing encouraging research in genetics, but current public knowledge, awareness, and perception of this area remain unknown for Brunei Darussalam. This study aimed to investigate the Brunei population’s genetics and genetic testing literacy, and their attitude toward them. A cross-sectional study was carried out targeting public population in Brunei Darussalam. Questionnaires on knowledge and attitudes were randomly distributed in frequented venues in the Brunei–Muara district and uploaded online for distribution through social media. Responses were scored and analyzed using appropriate statistical methods. Overall, the sample population (n = 474) comprised 75.7% female, 64.3% aged 18–29 years old, 39.7% with a bachelor’s degree, and 2.3% and 5.3% with a personal history and family history of genetic disease(s), respectively. Younger participants scored higher for disease-related questions and showed more concern on the impact of testing on employment but were more fearful of testing. Higher educational qualifications were associated with a higher knowledge score, a more optimistic view on DNA research, and less reluctance to take a genetic test for an untreatable disease. Participants with a personal history of genetic disease(s) were more knowledgeable and displayed higher curiosity. Participants with a family history of genetic disease(s) were also more knowledgeable and would want testing even for an untreatable disease. Significantly less was known about the social consequences of testing compared to the medical possibilities. Investigating the knowledge and attitudes of the population is vital preceding efforts toward national adaptation of genetic testing, keeping in mind the various obstacles and issues surrounding the subject.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
