    INTRODUCTION: The increasing rate of breast cancer (BC) incidence in Malaysia hints a lack of awareness among Malaysians. One (1) woman out of nineteen (19) is at risk with BC and almost up to fifty percent (50%) of women diagnosed with BC were reported to be under the age of fifty (50). Our main concern is to study the level of awareness among the women on risk factors, clinical manifestations, diagnosis, preventions and treatments.

    METHOD: A cross-sectional study was conducted exclusively among women in the public with total sample of three hundred and forty six (346), questionnaires were distributed using a simple random technique. Data was collected and analyzed by student T test in SPPS version 20.

    RESULTS: Our study reveals insufficient awareness on BC. Overall, awareness on risk factors is inadequate, but good knowledge on the importance of family history and diet as risk factors are discovered. Awareness on the cause and clinical manifestations of BC is required for improvement. As for treatment, alternatives especially surgery and chemotherapy are unclear to public, public is remotely unwitting on cessation of smoking to prevent BC at the early stage.

    CONCLUSION: Malaysian has spaces for improvement on awareness of BC in terms of risk factors, clinical manifestations, diagnosis, treatment and prevention. Early detection can be achieved with good awareness because it leads to better prognosis and lower mortality.

    Introduction: Metastatic tumors of the temporal bone are extremely rare. Collet-Sicard syndrome is an uncommon condition characterized by unilateral palsy of the lower four cranial nerves. The clinical features of temporal bone metastasis are nonspecific and mimic infections such as chronic otitis media and mastoiditis.

    Case Report: This report describes a rare case of metastatic adenocarcinoma of the temporal bone causing Collet-Sicard syndrome, presenting with hearing loss, headache and ipsilateral cranial nerve palsies. The patient was a 68-year old woman initially diagnosed with extensive mastoiditis and later confirmed as having metastatic adenocarcinoma of the temporal bone, based on histopathologic findings.

    Conclusion: Clinical presentation of metastatic carcinoma of the temporal bone can be overshadowed by infective or inflammatory conditions. This case report is to emphasize the point that a high index of clinical suspicion is necessary for the early diagnosis of this aggressive disease which carries relatively poor prognosis. This report highlights that it is crucial to suspect malignant neoplasm in patients with hearing loss, headache and cranial nerve palsies.

    Renal cell carcinoma (RCC) is the commonest from of renal neoplasm. Although surgery is a successful curative treatment for localized RCC, most patients are diagnosed with advanced or metastatic RCC, which has poor prognosis. RCC is classified by stage and grade using tissue samples. Whilst these provide good prognostic information, they are not very useful for early detection. Proteins that are dysregulated in patient's serum can be a valuable alternative and less invasive biomarker for early detection of the disease. For this reason, a hypothesis was formed that leptin is a possible biomarker for early detection and prognostication of RCC. The literature has disparate results on the usefulness of leptin as a biomarker for the early detection of RCC. Hence, a systematic review and a meta-analysis was carried out to investigate whether serum leptin could be a reliable diagnostic and prognostic factor in RCC patients. Literature on the available cohort and case-control studies on serum leptin in RCC was searched in electronic databases and included to evaluate this adipokine in the progression of RCC. The relevant studies were evaluated for the diagnostic and prognostic value of leptin in RCC patients. Overall, only 6 original research studies matched selection criteria and were included for meta-analysis. This study was hypothesised that; leptin might be a useful biomarker for early detection and prognostication of RCC. However, the data were presented in this study did not support our hypothesis. Serum leptin levels in RCC patients do not strongly associate with the development or progression of RCC, thus cannot act as a biomarker for early detection in RCC in patients. Extending our hypothesis further to include levels of obesity and RCC development may be worthwhile, but studies are currently limited.

    In Malaysia, gastric cancer (also known as stomach cancer) is diagnosed at a complex stage and has poor prognosis. Most mortality cases due to gastric cancer diseases are potentially preventable. Thus greater efforts are needed for gastric cancer awareness to give adequate knowledge for Malaysians in order to be more cautious or alert in diagnosing the ailment much earlier. After all, early detection is the key towards improving the survival rate in gastric cancer patients. Hence, the aim of this study is to assess the youngsters’ awareness on the risk factors of gastric cancer. A survey using online forms was conducted on 350 students of UiTM Melaka, Alor Gajah Campus, to assess their awareness of risk factors regarding gastric cancer. Based on the regression analysis conducted, it can be highlighted that attitudes, knowledge, medication, education level and faculty (dummy) are some of the variables that were found to be the risk factors of the awareness on gastric cancer among these selected youngsters in the 21st century.

    Cervical cancer remains the fourth most common cancer in women, with 85% of deaths occurring in LMICs. Despite the existence of effective vaccine and screening tools, efforts to reduce the burden of cervical cancer must be considered in the context of the social structures within the health systems of LMICs. Compounding this existing challenge is the global COVID-19 pandemic, declared in March 2020. While it is too soon to tell how health systems priorities will change as a result of COVID-19 and its impact on the cervical cancer elimination agenda, there are opportunities to strengthen cervical screening by leveraging on several trends. Many LMICs maximized the strengths of their long established community-based primary care and public health systems with expansion of surveillance systems which incorporated mobile technologies. LMICs can harness the momentum of the measures taken against COVID-19 to consolidate the efforts against cervical cancer. Self-sampling, molecular human papillomavirus (HPV) testing and digital health will shift health systems towards stronger public health and primary care networks and away from expensive hospital-based care investments. While COVID-19 will change health systems priorities in LMICs in ways that may de-prioritize cervical cancer screening, there are significant opportunities for integration into longer-term trends towards universal health coverage, self-care and digital health.

    INTRODUCTION: The immunochemical fecal occult blood test (iFOBT) has been widely used for opportunistic colorectal cancer (CRC) screening in average-risk individuals seeking care from public health clinics in Malaysia. This study provides a 5-year outcome evaluation of such a practice.

    METHODS: The findings for a few outcome indicators, ranging from the iFOBT uptake to the CRC and polyp detection rates, were generated from the data contributed by 583 public health clinics between 2014 and 2018. The trends in their changes were also evaluated.

    RESULTS: The iFOBT uptake constantly increased over the years (p < 0.001), totaling 2.29 % (n = 127,957) as at 2018. Nearly 10 % (n = 11,872) of the individuals screened had a positive test result. Of those who underwent colonoscopy (n = 6,491), 4.04 % (n = 262) and 13.93 % (n = 904) were found to have CRC and polyps, respectively.

    CONCLUSION: An uptrend in the CRC screening uptake was witnessed following the introduction of the iFOBT in public health clinics.

    Early diagnosis of oral cancer results in less aggressive treatment and improves the quality of life and overall 5-year survival rate. Well-trained dental professionals can play a crucial role in the early detection of oral cancers. The present study aims to determine the effectiveness of the training program "OralDETECT", a spaced repetitive, test-enhanced learning tool with a corrective feedback mechanism for early detection of oral cancer. Thirty-two dentists and 259 dental students from three Malaysian dental schools were involved in this study. All participants were trained and calibrated to recognize oral potentially malignant disorders (OPMD) and oral cancer using "OralDETECT", which is comprised of a series of pre-test, lecture, post-tests and review sessions. The percentage of correct answers (scores) for each test given by the participants was calculated and analysed using a paired t test. It was found that the overall percentage of diagnostic accuracy for both dental professionals and student groups increased to above 80% from the pre-tests to the final post-tests. There was a significant improvement in overall scores between the pre-tests and all three post-tests for the dental professional groups and the student groups. The diagnostic accuracy for individual OPMD and lesions suspicious of oral cancer also increased to above 80% for both groups. The results of our study demonstrate that the "OralDETECT" is an efficient and effective competency tool which can be used to train dental professionals and students for the early detection of OPMD and oral cancer.

    BACKGROUND: Participation in colorectal cancer screening is still low among Malaysians despite the increasing trend of incidence, with more than half of the new cases being detected in the advanced stages. Knowledge improvement might increase screening participation and thus improve the chances of disease detection. With the advancement of communication technology, people nowadays prefer to read from their mobile phone using a Web browser or mobile apps compared with the traditional printed material. Therefore, health education and promotion should adapt this behavior change in educating the community.

    OBJECTIVE: This study aimed to document the process of designing and developing a mobile app for community education on colorectal cancer and assess the usability of the prototype.

    METHODS: The nominal group technique (NGT) was used for the content development of the mobile app. NGT involving community educationists and clinicians combined with community representatives as the target users identified relevant health information and communication strategies including features for a user-friendly mobile app. The prototype was developed using framework Ionic 1, based on the Apache Cordova and Angular JS (Google). It was published in the Google Play store. In total, 50 mobile phone users aged 50 years and above and who had never been diagnosed with any type of cancer were invited to download and use the app. They were asked to assess the usability of the app using the validated Malay version of System Usability Scale Questionnaire for the Assessment of Mobile Apps questionnaire. The One-sample t test was used to assess the usability score with a cut-off value of 68 for the usable mobile app.

    RESULTS: The Colorectal Cancer Awareness Application (ColorApp) was successfully developed in the local Malay language. The NGT discussion had suggested 6 main menus in the ColorApp prototype, which are Introduction, Sign and Symptoms, Risk Factors, Preventive Measures, Colorectal Cancer Screening Program, and immunochemical fecal occult blood test kit. A total of 2 additional artificial intelligence properties menus were added to allow user-ColorApp interaction: Analyze Your Status and ColorApp Calculator. The prototype has been published in the Google Play store. The mean usability score was 72 (SD 11.52), which indicates that ColorApp is a usable mobile app, and it can be used as a tool for community education on colorectal cancer.

    CONCLUSIONS: ColorApp mobile app can be used as a user-friendly tool for community education on colorectal cancer.

    Introduction: Cervical cancer is the third most common cancer among women in Malaysia with an estimation of 1,682 new cases and 944 deaths as reported in the year 2018, and these statistics are expected to increase by the year 2025. Early detection of cervical cancer through Pap smear screening may prevent an increase in incidence. Hence, this study was aimed to determine the knowledge, attitude and practice (KAP) towards Pap smear screening in the urban community. Methods: Cross-sectional study was conducted to determine the prevalence of Pap smear screening and association with KAP among 246 randomly selected women. Primary data was collected by using a self-administered online questionnaire and analysed using SPSS version 23. Results: Prevalence of Pap smear screen- ing was recorded at 46.6%. Mean score for knowledge was 0.858±0.247, the attitude was 0.847±0.156 and practice was 0.423±0.426. There is a significant difference in KAP towards Pap smear screening (p

    The identification of recurrent founder variants in cancer predisposing genes may have important implications for implementing cost-effective targeted genetic screening strategies. In this study, we evaluated the prevalence and relative risk of the CHEK2 recurrent variant c.349A>G in a series of 462 Portuguese patients with early-onset and/or familial/hereditary prostate cancer (PrCa), as well as in the large multicentre PRACTICAL case-control study comprising 55,162 prostate cancer cases and 36,147 controls. Additionally, we investigated the potential shared ancestry of the carriers by performing identity-by-descent, haplotype and age estimation analyses using high-density SNP data from 70 variant carriers belonging to 11 different populations included in the PRACTICAL consortium. The CHEK2 missense variant c.349A>G was found significantly associated with an increased risk for PrCa (OR 1.9; 95% CI: 1.1-3.2). A shared haplotype flanking the variant in all carriers was identified, strongly suggesting a common founder of European origin. Additionally, using two independent statistical algorithms, implemented by DMLE+2.3 and ESTIAGE, we were able to estimate the age of the variant between 2300 and 3125 years. By extending the haplotype analysis to 14 additional carrier families, a shared core haplotype was revealed among all carriers matching the conserved region previously identified in the high-density SNP analysis. These findings are consistent with CHEK2 c.349A>G being a founder variant associated with increased PrCa risk, suggesting its potential usefulness for cost-effective targeted genetic screening in PrCa families.

    Breast cancer is commonest disease amongst women throughout the world and the second leading cause of women’s death. Since 2014, it was reported that approximately 5000 women
    were diagnosed with breast cancer every year in Malaysia. Adoption of mammography screening
    amongst Malaysian women remains under-utilized because it depends on self-initiatives of
    individuals. Amongst the perceived barriers are low knowledge, cost, embarrassment and pain which may then give a negative psychological aspect to health behavior actions. The study aims to determine the level of knowledge and perceived barriers pertaining to mammography amongst female lecturers in Kulliyah of Allied Health Sciences (KAHS), International Islamic University Malaysia (IIUM) Kuantan, Pahang. Methods: A survey was carried out on female lecturers aged 35 years and above in KAHS, IIUM Kuantan. A self-administered questionnaire which consists of three sections; demographic factors, knowledge about breast cancer and perceived barriers pertaining to
    mammography were distributed to 30 respondents. Data was analyzed using SPSS version 19.0.
    Results: The mean age of respondents was 39.9 years old (SD ± 5.15). Majority of respondents possessed good knowledge of breast cancer. The perceived barriers pertaining to mammography amongst respondents were pain and the procedure being expensive. Conclusions: This study found that most female lecturers in KAHS, IIUM Kuantan possessed good knowledge on breast cancer but have fair knowledge pertaining to breast lumps and the best time for breast screening. The perceived barriers amongst respondents were pain and cost of the procedure.

    Background: Mammography screening tends to reduce mortality rate through early detection. One of the barriers to mammography screening is fear of negative appearance evaluation(FNAE). This study investigated the impact of internal health locus of control, breast cancer worries and age on the relationship between FNAE and attitude towards mammography. Methods: A cross-sectional, questionnaire-based survey design was used. Samples were Iranian women, living in Iran, aged at least 30 years old, without any history of cancer, and had not performed mammography previously based on self-report. In total, 823 samples were collected through conducting an online survey from April to June 2016. The questionnaire consisted of several instruments including attitude toward breast cancer screening procedures scale, FNAEscale, the internal dimension of the multidimensional health locus of control, and two items to measure breast cancer worry. Using covariance-based structural equation modeling the model was tested. Results: The interaction of FNAE with internal health locus of control (β = -0.128, P<0.05,CI: -0.200, -0.056), breast cancer worry (β = 0.090, P<0.05, CI: -0.162, -0.017), and age (β =-0.095, P<0.05, CI = -0.163, -0.026) was significant. The three tested moderators dampened the positive relationship between FNAE and negative attitude towards mammography. Conclusion: More information about the screening procedure should be given to women to overcome their fear. The findings indicate the need for interventions seeking to shift women's health locus of control from external to internal. Women with low level of cancer worry need more attention.

    In Malaysia nasopharyngeal carcinoma (NPC) is ranked as number fourth (5.2%) from all cancer and third (8.4%) most common cancer among male population. Nasopharyngeal carcinoma in Malaysia mostly occurs among Chinese (49%), followed by natives of Sabah and Sarawak (28%) and Malay (22%). There were multiple researches done to determine the risk factors for nasopharyngeal carcinoma and most of them from western pacific region. Prevalence of nasopharyngeal carcinoma in Sabah in 2013 is about 106 cases while in 2012 is 75 cases. It shows almost 30% increment from previous year. A total of 53 patients were diagnosed NPC in 2013 from Kota Kinabalu locality and it contributes more than 50% from total prevalence NPC in 2013. NPC is common in local Sabahan, especially in Kadazan and Dusun ethnicity. In 2013, the youngest are 11 years old and the eldest are 84 years old. The upward trend of NPC cases in younger age group is worrisome for us. Thus it is very important to determine the risk factors associated with NPC and this would help the health provider and other stakeholders to do planning in prevention of NPC such as awareness programme or cancer screening for the target high risk group especially for Sabah population.

    Background: Cervical cancer health education programmes are not accessible to rural women in developing countries.

    Objective: Our study aimed at assessing the health literacy about cervical cancer amongst the rural women in Udupi district, southern India, before and following intervention using audio-visual aid/face-to-face interactive sessions versus pamphlets alone.

    Methods: This was a quasi-experimental study. A total of 166 women participated in the study. Participant groups were allocated into two interventional (Experimental/Control) groups. Participants in the experimental group received education through the video followed by face-to-face interaction with a health educator while those in the control group received a pamphlet. A validated questionnaire was used to assess knowledge about numerous risk factors, Pap smear test and treatment of cervical cancer (pre- and post-intervention test). The findings are presented as frequencies and percentages. Paired responses were compared for individual questions using McNemar test and P < 0.05 was fixed as statistically significant.

    Results: Former to the intervention, 13.5% and 19.1% in the experimental and control groups, respectively, felt that personal hygiene was important to prevent cervical cancer. Both the groups had very limited knowledge regarding risk factors (93.6%; 94%), symptoms (96.3%; 97.6%) and knowledge that Pap smears can reduce the risk of cervical cancer (91.7%; 93.9%). The change in knowledge pre-and post-intervention in both groups increased significantly.

    Conclusion: Intervention with face-to-face interactive sessions showed a positive impact on knowledge regarding cervical cancer. These findings indicate both methods can be effective in providing health education in the community.

    Background/aim: In Malaysia, breast cancer is the most common cancer among women. As such, early diagnosis and screening practices are important to increase the survival rate. Breast self-examination (BSE) is one of the main screening methods for breast cancer. Socio-demographic characteristics and knowledge of breast cancer are amongst the crucial roles in determining women's behavioral adoption in performing BSE. This study aims to assess the relationship of socio-demographic factors and knowledge of breast cancer on the stage of behavioral adoption of BSE among Malaysian women in Kuantan, Pahang.

    Materials and methods: A cross-sectional study was conducted on 520 women from three different government health clinics in Kuantan and IIUM Family Health Clinic from February to April 2018. Data were collected using a self-administered questionnaire on socio-demographic factors and knowledge of breast cancer and its effect on the behavioral adoption of BSE.

    Results: Significant difference was found between socio-demographic characteristics and behavioral adoption of BSE. However, only breast screening and the best time for screening were found to be significant with the behavioral adoption of BSE and knowledge of breast cancer.

    Conclusion: It is found that most women in Kuantan, Pahang perform BSE but were still unaware of the importance of performing BSE for early breast cancer detection. This study was expected to enhance women's awareness of the benefits of performing BSE.

    INTRODUCTION: Colorectal cancer (CRC) imposes a significant global burden of disease. CRC survival rates are much lower in low-income and middle-income countries (LMICs). Screening tends to lead to an improvement in cancer detection and the uptake of available treatments and, in turn, to better chances of cancer survival. Most evidence on CRC screening interventions comes from high-income countries. The objective of this scoping review is to map the available literature on the implementation of CRC screening interventions in LMICs.

    METHODS AND ANALYSIS: We will conduct a scoping review according to the framework proposed by Arksey and O'Malley (2005). We will search MEDLINE, EMBASE, Web of Science and Google Scholar using a combination of terms such as "colorectal cancer", "screening" and "low-middle-income countries". Studies of CRC screening interventions/programmes conducted in the general adult population in LMICs as well as policy reviews (of interventions in LMICs) and commentaries on challenges and opportunities of delivering CRC screening in LMICs, published in the English language before February 2020 will be included in this review. The title and abstract screen will be conducted by one reviewer and two reviewers will screen full-texts and extract data from included papers, independently, into a data charting template that will include criteria from an adapted template for intervention description and replication checklist and implementation considerations. The presentation of the scoping review will be reported according to the Preferred Reporting Items for Systematic Reviews and Meta-Analysis extension for Scoping Reviews guidance.

    ETHICS AND DISSEMINATION: There are no ethical concerns. The results will be used to inform colorectal screening interventions in LMICs. We will publish the findings in a peer-reviewed journal and present them at relevant conferences.

    Purpose: Computer-aided detection (CAD) alerts radiologists to findings potentially associated with breast cancer but is notorious for creating false-positive marks. Although a previous paper found that radiologists took more time to interpret mammograms with more CAD marks, our impression was that this was not true in actual interpretation. We hypothesized that radiologists would selectively disregard these marks when present in larger numbers. Approach: We performed a retrospective review of bilateral digital screening mammograms. We use a mixed linear regression model to assess the relationship between number of CAD marks and ln (interpretation time) after adjustment for covariates. Both readers and mammograms were treated as random sampling units. Results: Ten radiologists, with median experience after residency of 12.5 years (range 6 to 24) interpreted 1832 mammograms. After accounting for number of images, Breast Imaging Reporting and Data System category, and breast density, the number of CAD marks was positively associated with longer interpretation time, with each additional CAD mark proportionally increasing median interpretation time by 4.35% for a typical reader. Conclusions: We found no support for our hypothesis that radiologists will selectively disregard CAD marks when they are present in larger numbers.

    Music is one of the suggested interventions that can reduce stress caused by pain from mammography procedures. The different types of music might affect the anxiety level during a mammogram screening. Thus, the study aimed to determine the anxiety level of women who underwent mammogram screening according to different types of music. A cross-sectional study was conducted on 60 women by using the purposive sampling technique in the radiology department at randomly selected private hospitals in Klang Valley from November 2018 to November 2019. Respondents were randomly divided based on the day of mammogram screening into two groups; namely slow and upbeat music. Descriptive analysis was used to determine the anxiety level for each group and T-test analysis was used to compare the significance of anxiety level between both groups. A total of 60 respondents had participated in this study with a total of 30 (50.0%) respondents allocated in slow music, while another 30 (50.0%) respondents were allocated in upbeat music. Patients who underwent mammography screening while listening to slow music had a high anxiety level (70.0%) as compared to upbeat music group (63.3%). There was no significant effect for music, t (60) = -0.54, p = 0.59, despite slow music (M = 1.70, SD = 0.47) attaining higher anxiety level than the upbeat music (M = 1.63, SD = 0.49). Upbeat music has the potential in reducing the anxiety level of women undergoing mammography screening.

    Introduction: Detecting breast cancer at earlier stage is crucial to increase the survival rate. Mammography as the golden screening tool has shown to be less effective for younger women due to denser breast tissue. Infrared Ther- mography has been touted as an adjunct modality to mammography. Further investigation of thermal distribution in breast cancer patient is important prior to its clinical interpretation. Therefore, thermal profiling using 3D compu- tational simulation was carried out to understand the effect of changes in size and location of tumour embedded in breast to the surface temperature distribution at different breast densities. Methods: Extremely dense (ED) and pre- dominantly fatty dense (PF) breast models were developed and simulated using finite element analysis (FEA). Pennes’ bioheat equation was adapted to show the heat transfer mechanism by providing appropriate thermophysical prop- erties in each tissue layer. 20 case studies with various tumour size embedded at two asymmetrical positions in the breast models were analysed. Quantitative and qualitative analyses were performed by recording the temperature values along the arc of breast, calculating of temperature difference at the peaks and comparing multiple thermal images. Results: Bigger size of tumour demands a larger increase in breast surface temperatures. As tumour is located far from the centre of the breast or near to the edge, there was a greater shift of temperature peak. Conclusion: Size and location of tumour in various levels of breast density should be considered as a notable factor to thermal profile on breast when using thermography for early breast cancer detection.

    The importance of nanotechnology in medical applications especially with biomedical sensing devices is undoubted. Several medical diagnostics have been developed by taking the advantage of nanomaterials, especially with electrical biosensors. Biosensors have been predominantly used for the quantification of different clinical biomarkers toward detection, screening, and follow-up the treatment. At present, ovarian cancer is one of the severe complications that cannot be identified until it becomes most dangerous as the advanced stage. Based on the American Cancer Society, 20% of cases involved in the detection of ovarian cancer are diagnosed at an early stage and 80% diagnosed at the later stages. The patient just has a common digestive problem and stomach ache as early symptoms and people used to ignore these symptoms. Micro ribonucleic acid (miRNA) is classified as small non-coding RNAs, their expressions change due to the association of cancer development and progression. This article reviews and discusses on the currently available strategies for the early detection of ovarian cancers using miRNA as a biomarker associated with electrical biosensors. A unique miRNA-based biomarker detections are specially highlighted with biosensor platforms to diagnose ovarian cancer.
