    Multiple barriers impede the transformation of evidence-based research into implementation of cervical cancer screening in ASEAN countries. This review is the first of its kind to show the disease burden of cervical cancer, progress till date to implement screening and corresponding challenges, and propose tailored solutions to promote cervical cancer prevention in ASEAN. In 2020, approximately 69 000 cervical cancer cases and 38 000 deaths happened in ASEAN, and more than 44% and 63% increases on new cases and deaths are expected in 2040. Only four countries have initiated population-based cervical cancer screening programs, but the participation rate is less than 50% in some countries and even lower than 10% in Myanmar and Indonesia. Inequity and unavailability in service delivery, lack of knowledge and awareness, limited follow-up and treatment capacity, and funding sustainability affect successful scale-up of cervical cancer screening most in ASEAN. Implementing HPV detection-based primary screening, appropriate management of screen-positives, enhancing health education, integrating health services can accelerate reduction of cervical cancer burden in ASEAN. Achieving high screening coverage and high treatment compliance will help ASEAN countries remain aligned to cervical cancer elimination strategies.

    The study was conducted to determine the pick-up rate of abnormal cervical smears and the prevalence rate of cervical cancer in women aged 60 years and above and the demographic characteristics of the women screened. The pick-up rate of abnormal cervical smears was 1.65%. The prevalence rate for cervical intraepithelial neoplasia and frank carcinoma was 6.4 and 5.0 per thousand women screened respectively. The study group comprised 89.7% Chinese, 4.7% Malays, 3.6% Indians and 2.0% Others. The pick-up rate of abnormal smears was 1.9% in the Chinese and 1.3% in the Indians. There were no abnormal smears in the Malays and Others. The results demonstrate the importance of a routine cervical cancer screening programme among elderly women aged 60 years and above in Singapore.

    BACKGROUND: Cervical cancer is preventable. In Malaysia, women are found to have good awareness of the disease and yet, the Pap smear uptake is still poor. Measuring health literacy level could explain this discrepancy. This study aims to determine the relationship between health literacy, level of knowledge of cervical cancer and Pap smear with attitude towards Pap smear among women attending pre-marital course.

    METHODS: A cross sectional study was performed in three randomly selected centres that organised pre-marital courses. All Malay Muslim women participants aged 18 to 40 years old were recruited while non-Malaysian, illiterate, and had hysterectomy were excluded. Validated self-administered questionnaires used were European Health Literacy Questionnaire (HLS-EU-Q16 Malay) and Knowledge and attitude towards Cervical Cancer and Pap Smear Questionnaire. The mean percentage score (mean± SD) was calculated, with higher scores showed better outcomes. Multiple linear regression was used to measure the relationship of independent variables with attitude towards Pap smear.

    RESULTS: A total of 417 participants were recruited with a mean age of 24.9 ± 3.56 years old. Prevalence of awareness of cervical cancer was 91.6% (n=382, 95% CI: 89.0%, 94.2%) and mean percentage score was 74.7%±7.6. Prevalence of awareness of Pap smear was 59.0% (n=246, 95% CI: 54.2%, 63.8%) and mean percentage score was 80.2% ± 6.5. The health literacy mean score was 13.3±3.6, with minimum score 0 and maximum score 16. The mean percentage score of attitudes towards Pap smear was 64.8%±9.3. Multiple linear regression analysis demonstrated significant relationship between health literacy (p=0.047) and knowledge of Pap smear (p<0.001) with attitude towards Pap smear.

    CONCLUSION: A higher health literacy with high knowledge of Pap smear improves the attitude towards Pap smear. Pre-marital course is an opportunistic platform to disseminate information to improve health literacy and knowledge of cervical cancer and Pap smear screening.

    During the five-year period from January 1985 to December 1989 a total of 27,208 women, representing 44.0% of the total female population over age 15 years in Brunei Darussalam, underwent a cytologic examination. The majority of them were Malays (62.32%), followed by Chinese (22.23%), while the remainder were the expatriate population living in the country. High grade squamous intraepithelial lesion (moderate dysplasia) was detected in 88 women (3.3/1,000), high grade squamous intraepithelial lesion (carcinoma in situ) was seen in 32 women (1.22/1,000), and invasive carcinoma was found in 43 women (1.37/1,000). The overall detection rate for cervical cancer was 2.79/1,000 women in the population screened. In Brunei Darussalam Malay women marry at an early age, 44% by the age of 19 years, leading to sexual contact before the age of 20. However, the incidence of cervical cancer is low among them. This could be because they belong to the Orthodox Muslim Society, in which promiscuity is not permitted. Hence, multiple sex partners could be an important factor in the etiology of cervical cancer, confirming the current trend of thought that cervical cancer is a sexually transmitted disease. A comparison of the epidemiologic risk factors among the various races living in Brunei Darussalam is made.

    Association of High-risk Human Papillomavirus (HR-HPV) with oral cancer has been established recently. Detecting these viruses in oral cavity is important to prevent oral lesions related to them. The purpose of this study was to evaluate the prevalence of HR-HPV in the oral cavity of women with cervical cancer, and their children. A total of 70 women, previously diagnosed with cervical cancer, and 46 children of these women, born by vaginal delivery only, were selected for this study. Buccal swabs were collected from their oral cavity and HPV detection was carried out using Hybrid Capture 2 high-risk HPV (HC2 HR-HPV) detection system.

    Cancer of the cervix is exceedingly uncommon in the Malaysian Orang Asli (aborigine), despite the presence of factors associated with an increased risk of developing this malignancy. In only three patients was the diagnosis of carcinoma of the cervix established, out of a total of nearly 18,000 female inpatients, admitted to the Gombak Orang Asli Hospital over a 13-year period. Over this same period, 81 female patients were diagnosed as having cancer. Interviews with female Orang Asli patients show the presence of alleged risk factors for cervical cancer, including early age of first intercourse, multiparity and non-circumcision of husbands. The low incidence of cancer of the cervix in this aborigine community may be due to the strict moral code of the Orang Asli, limiting extramarital sexual activity and associated venereal infection.

    Background: The national cervical cancer screening program in Thailand has been successful in reducing overall burden from this disease. However, evaluation on spatial and temporal scales is needed to assess the efficacy of this program in smaller regions. Here, we geographically assess incidence in a province with a uniquely heterogeneous distribution of lifestyle factors associated with religiosity.

    Methods: Cervical cancer cases were extracted from the provincial cancer registry from 1989 to 2013. Age-adjusted incidence rates were calculated using population statistics from the census bureau and adjusted to the Segi world standard population. Bayesian hierarchical modelling was employed to spatiotemporally map cervical cancer incidence trends in Songkhla province in 5-year period.

    Results: Overall, the incidence of cervical cancer decreased in Songkhla province. The three districts with a Muslim population of greater than 70% had consistently lower cervical cancer rates from 1989 to 2013 compared with the rest of the predominantly Buddhist districts. Hotspots of incidence were identified in Sadao, Hat Yai and the juncture of Mueang Songkhla and Singhanakhon in each 5-year period.

    Conclusions: Distinct cervical cancer incidence trends by religion over time indicate differences in sexual habits, lifestyle and religion-associated culture between Muslims and Buddhists, and suggest divergent risk factor profiles for these groups. The high incidence rates in Sadao and Hat Yai is likely explained by the main road to Malaysia, which runs across these two areas and has frequent commercial sex trade. Female sex workers should be targeted as a vulnerable population for screening efforts to address this continuing burden of cervical cancer.

    OBJECTIVE: Strong persuasive messaging by providers is a key predictor for patient acceptance of prophylactic human papillomavirus vaccination. We aimed to determine optimal messaging to promote human papillomavirus adolescent vaccination across different geographical sites.

    METHODS: Adolescent providers (n = 151) from Argentina, Malaysia, South Africa, South Korea, and Spain were surveyed on messages, family decision makers, and sources of communication to best motivate parents to vaccinate their adolescent daughters overall, and against human papillomavirus. Multivariate logistic regression assessed the likelihood of recommending messages specifically targeted at cervical cancer with providers' characteristics: gender, medical specialization, and previous administration of human papillomavirus vaccination.

    RESULTS: Mothers were considered the most important human papillomavirus vaccination decision makers for their daughters (range 93%-100%). Television was cited as the best source of information on human papillomavirus vaccination in surveyed countries (range 56.5%-87.1%), except Spain where one-on-one discussions were most common (73.3%). Prevention messages were considered the most likely to motivate parents to vaccinate their daughters overall, and against human papillomavirus, in all five countries (range 30.8%-55.9%). Optimal messages emphasized cervical cancer prevention, and included strong provider recommendation to vaccinate, vaccine safety and efficacy, timely vaccination, and national policy for human papillomavirus vaccination. Pediatricians and obstetricians/gynecologists were more likely to cite that the best prevention messages should focus on cervical cancer (OR: 4.2, 95% CI: 1.17 to 15.02 vs other medical specialists).

    CONCLUSIONS: Provider communication messages that would motivate parents to vaccinate against human papillomavirus were based on strong recommendation emphasizing prevention of cervical cancer. To frame convincing messages to increase vaccination uptake, adolescent providers should receive updated training on human papillomavirus and associated cancers, while clearly addressing human papillomavirus vaccination safety and efficacy.

    One hundred years ago cervical cancer was rapidly fatal, regardless of therapy rendered. Today with cytological screening, early diagnosis is possible and ablative therapy can be instituted in appropriate cases. The advent of coloscopy has helped reduce unnecessary cone biopsy for diagnosis. However, the same cannot be said of the use of cytology for screening endometrial cancer, and often endometrial tissue biopsy is necessary. Ovarian cancer is notoriously silent in its early stages and symptoms if present are generally non-specific. To date there is no other useful and reliable method for its early detection than routine pelvic examination. An annual cytological screening test for cervical cancer will give an opportunity for examination of the breasts, abdomen and pelvis. Screening techniques for female genital tract malignancies are discussed.

    This cross-sectional study comprises a questionnaire-based survey regarding knowledge about human papillomavirus and its vaccine among students in different educational fields at public and private universities in the city of Lahore in Pakistan. A 26-item questionnaire was used to attain the objective of this study. The reliability of this tool was assessed using Cronbach's alpha (0.79) and the Kaiser-Meyer-Olkin value was 0.827. The response rate to the survey was 78.0%, of whom the majority (74.9%) were females and 308 (79%) were single (median age=23 years). While assessing the respondents' knowledge about HPV, 223(57%) students reported that they had already heard of HPV (human papillomavirus) and nearly 215 (55%) reported that HPV causes cervical cancer and can infect both men and women. Gender and field of study were two main factors found influencing the respondents' knowledge about HPV. Moreover, students' understanding about the mode of transmission of HPV was cursory: 40.51% said they did not know how HPV is transmitted, 133 (34.10%) stated that HPV spreads through the exchange of bodily fluids, and 22 (5.64%) selected cough/sneezing. In terms of prevention, 175 (44.87%) students stated that HPV can be prevented by vaccination, 30.0% reported sexual abstinence, 21.54% using condoms, and nearly 5.38% disclosed use of antibiotics. Addressing the knowledge of students regarding HPV vaccine, nearly 53% stated there is no vaccine against HPV and almost 64% rejected the statement that HPV vaccine prevents cervical cancer. In addition, students reported that they will be more than willing to get vaccinated for HPV if their physician recommend them (RII=0.74) followed by parents (RII=0.69). The results of this study revealed a poor understanding among respondents about the health problems associated with HPV, its prevention, modes of transmission and arability of HPV vaccine in Pakistan.

    Persistent high-risk human papillomavirus (HPV) infection is known to play an important role in the genesis of cervical cancer. Since new screening and prevention strategies, namely improved HPV testing and HPV vaccination have been aggressively promoted recently, it is crucial to investigate the HPV distribution in Malaysia in order to maximize their cost-effectiveness. This study was therefore conducted to assess the HPV type distribution in the most populous region, the state of Selangor. A total of 200 cervical swab samples were collected in two health-screening campaigns, and also from women attending obstetrics and gynecology clinics in several hospitals in Selangor. DNA extraction was performed and HPV DNA was detected via nested PCR using MY09/MY11 as outer primers and GP5+/GP6+ as inner primers which target the L1 gene of the viral genome. The purified PCR products were subjected to automated DNA sequencing to determine the HPV genotype. Out of 180 β-globin positive samples, 84 (46.7%) were positive for HPV DNA. The most common HPV type found was high-risk oncogenic type 16 (40%), followed by HPV type 18 (3.3%), HPV 33 (1.7%), HPV 31 (0.6%), and low-risk HPV 87 (0.6%). Our study confirmed that nested PCR method is highly sensitive in detecting HPV DNA even in low risk patients. Since a relatively high prevalence rate of HPV infection was found in this population, prompt healthcare policy changes to bring about implementation of early HPV vaccination program is desirable to prevent a high incidence of cervical cancer.

    OBJECTIVES: Many developing countries, including Malaysia, will need to continue relying on cervical screening because they will not be able to cover their entire female adolescent populations with HPV vaccination. The aim of this paper was to establish the extent of the health care, informational, financial and psychosocial barriers to cervical screening in Malaysia.

    METHODS: A literature search was made for reports on implementation, perceptions and reception of cervical screening in Malaysia published between January 2000 and September 2008.

    RESULTS: Despite offering Pap smears for free since 1995, only 47.3% of Malaysian women have been screened. Several factors may have contributed to this. No national call-recall system has been established. Women are informed about cervical screening primarily through mass media rather than being individually invited. Smears are free of charge if taken in public hospitals and clinics, but the waiting times are often long. The health care system is unequally dense, with rural states being underserved compared to their urban counterparts. If the screening coverage was to increase, a shortage of smear-readers would become increasingly apparent.

    CONCLUSIONS: Improving screening coverage will remain an important strategy for combating cervical cancer in Malaysia. The focus should be on the policy-making context, improving awareness and the screening infrastructure, and making the service better accessible to women.

    Cervical cancer remains one of the leading causes of cancers in women from Indonesia, Malaysia, the Philippines, Thailand and Vietnam. High-risk human papillomavirus (HPV) types, particularly HPV-16 and 18, are consistently identified in cervical cancer cases regardless of geographical region. Factors that have been identified to increase the likelihood of HPV exposure or subsequent development of cervical cancer include young age at first intercourse, high parity and multiple sexual partners. Cervical cancer screening programs in these countries include Pap smears, single visit approach utilizing visual inspection with acetic acid followed by cryotherapy, as well as screening with colposcopy. Uptake of screening remains low in all regions and is further compounded by the lack of basic knowledge women have regarding screening as an opportunity for the prevention of cervical cancer. Prophylactic HPV vaccination with the quadrivalent vaccine has already been approved for use in Malaysia, the Philippines and Thailand, while the bivalent vaccine has also been approved in the Philippines. However, there has been no national or government vaccination policy implemented in any of these countries.

    INTRODUCTION: Kelantan is one of the states in Malaysia which has a high prevalence of type 2 diabetes (DM2). Other than with endometrial carcinoma, the association of DM2 with particular female cancers is not known.
    OBJECTIVE: To determine the proportion of breast, cervical, ovarian and endometrial cancers among females with DM2 diagnosed in Hospital Universiti Sains Malaysia (HUSM) over an 11 year period.
    MATERIALS AND METHODS: All histologically confirmed cases of breast, endometrial, cervical and ovarian carcinomas admitted to the Hospital were included in the study. The patient diabetic status was traced from the hospital medical records.
    RESULTS: There was a total of 860 cases of breast, cervical, ovarian and endometrial carcinomas over this period. Breast carcinoma was the commonest, accounting for 437/860 (50.8%) followed by cervix, 159/860 (18.5%), ovarian, 143/860 (16.6%) and endometrial carcinomas, 121/860 (14.1%). Out of these, 228/860 (26.5%) were confirmed diabetics. Endometrial carcinoma patients showed the highest proportion being diabetics, 42.1% (51/121), followed by ovarian cancer, 25.9% (37/143), breast carcinoma, 23.6% (103/437) and cervical cancer 23.3% (37/159).
    CONCLUSIONS: There is a significant proportion of DM2 among women with these four cancers, endometrial carcinoma being the highest followed by ovarian, breast and cervical carcinoma. The rising trend of these four cancers is in tandem with an increasing trend of DM2 in the community. In populations where diabetes is prevalent, screening for epithelial cancers should be rigourous. Diabetic clinics should include screening for these cancers among their female patients and gynecology clinics should screen the women they treat for their diabetes status.

    Human papillomavirus (HPV) is a prevalent sexually transmitted infection with serious medical, sexual, and relationship consequences. HPV vaccine protection is available globally but unfortunately vaccine uptake is inconsistent everywhere. From this study, it was observed that the awareness of cervical cancer, HPV virus and HPV vaccination in Malaysia is high, at 83.1%, 73.9% and 73.3% of respondents, respectively. However, a considerably low percentage had undergone HPV vaccination (8.6%) compared to those who had experienced a Pap smear (32.9%). Awareness between cervical cancer and HPV virus and vaccination was low. Health care providers and the governing bodies have to play a vital role in disseminating holistic information on the vaccine and the importance of getting vaccinated to the public more vigorously in Malaysia.

    OBJECTIVE: The objective of this study was to determine the histopathological features and cell morphology of various cervical lesions observed among Malaysian women.

    METHODOLOGY: A retrospective study was conducted to evaluate 77 cervical cases collected from the histopathology laboratory of Ipoh hospital from 1st January, 2005, to 31st December, 2006.

    RESULTS: Cervical intraepithelial neoplasia (CIN) was found in 33 (42%) cases, CIN III accounting for 27%, and CIN I, CIN II and CIN II-III 5% each. The highest rate for CIN cases was 43% in the 41-50 year age group and the lowest rate was 6% in the group aged 61-70 years. Non-keratinizing and metastatic squamous cell carcinomas (SCCs) accounted for 16% and 13%, respectively, the combination being second in majority (29%), followed by adenocarcinoma (17%). The histopathological results showed CIN I to be characterized by mild papillary projections of the epithelium with some degree of nuclear enlargement, pleomorphism, mild koilocytosis, bionucleated cells and a low nucleo-cytoplasmic ratio. CIN II demonstrated typical squamous epithelium with disorganization of the lower part of the epithelium accompanied by nuclear hyperchromatism, an increased nucleo-cytoplasmic ratio, and scanty mitotic figures. CIN III was characterized by pleomorphic nuclei, atypical cells with mitotic figures, nucleo-cytoplasmic ratio, anisokaryosis and hyperchromasia.

    CONCLUSION: Lesions related to cervical cancer showed tumor progression correlating with histopathological changes in cell morphology.
