MATERIALS AND METHODS: This was an experimental before and after study performed between October 2014 and March 2015. Five hundred and eighty students were randomly assigned into intervention and control groups. All were required to complete both pre-intervention and post-intervention questionnaires. Those in the intervention group were given an information leaflet to read before answering the post-intervention questionnaire.
RESULTS: Almost half (48.3%) of the students had poor knowledge, with a score less than 5, and only 51 (8.8%) exhibited good knowledge, with a score of 11 and above. After educational intervention, the number of students with poor knowledge was reduced to 177 (29.3%) and the number of students who exhibited good knowledge increased to 148 (25.5%). Students from the intervention group demonstrated significant higher total scores in knowledge regarding 'HPV infection and cervical cancer' (p=0.000) and 'HPV vaccination and cervical cancer prevention' (p=0.000) during post-intervention as compared to the control group.
CONCLUSIONS: Knowledge on HPV infection and vaccination is low among pre-university students. Educational intervention in the form of information leaflets appears effective in creating awareness and improving knowledge.
METHODS: The following electronic resources were searched: Medline @EBSCOHOST(Medline), Embase, PubMed, and CINAHL databases. Manual searches were also conducted. The main outcome of interest was the acceptability of HPV DNA testing by self-sampling in comparison with clinician-collected sampling.
RESULTS: In total, 23 articles were included in this systematic review. The majority (19 studies) were quantitative intervention studies and 4 studies were qualitative observational studies. Eleven studies reported a preference for self-sampling by women compared with clinician-collected sampling (64.7%-93%). The remaining studies found that women preferred clinician-collected sampling because mainly of respondents' lack of confidence in their ability to complete self-sampling correctly. In most articles reviewed, the studied associated factors, such as demographic factors (age, marital status, and ethnicity), socioeconomic factors (income, education level), reproductive factors (condom use, number of children, current use of contraception, and number of partners), and habits (smoking status) were not found to be significantly associated with preference.
CONCLUSIONS: Both methods of sampling were found to be acceptable to women. Self-sampling is cost-effective and could increase the screening coverage among underscreened populations. However, more information about the quality, reliability, and accuracy of self-sampling is needed to increase women's confidence about using to this method.
MATERIALS AND METHODS: This was a multicentre study with a total of 280 cases of cervical cancer from 4 referral centres in Malaysia, studied using real-time polymerase chain reaction (qPCR) detection of 12 high risk-HPV genotypes.
RESULTS: Overall HPV was detected in 92.5% of cases, in 95.9% of squamous cell carcinomas and 84.3%of adenocarcinomas. The five most prevalent high-risk HPV genotypes were HPV 16 (68.2%), 18 (40%), 58 (10.7%), 33 (10.4%) and 52 (10.4%). Multiple HPV infections were more prevalent (55.7%) than single HPV infections (36.8%). The percentage of HPV positive cases in Chinese, Malays and Indians were 95.5%, 91.9% and 80.0%, respectively. HPV 16 and 18 genotypes were the commonest in all ethnic groups. We found that the percentage of HPV 16 infection was significantly higher in Chinese (75.9%) compared to Malays (63.7%) and Indians (52.0%) (p<0.05), while HPV 18 was significantly higher in Malays (52.6%) compared to Chinese (25.0%) and Indians (28%) (p<0.05). Meanwhile, HPV 33 (17.9%) and 52 (15.2%) were also more commonly detected in the Chinese (p<0.05).
CONCLUSIONS: This study showed that the distribution of HPV genotype in Malaysia is similar to other Asian countries. Importantly, we found that different ethnic groups in Malaysia have different HPV genotype infection rates, which is a point to consider during the implementation of HPV vaccination.
METHODS: Women older than 21 years with a histologic diagnosis of ICC and cervical intraepithelial neoplasia [CIN 2 or 3 and adenocarcinoma in situ (AIS)] were enrolled. Cervical specimens were reviewed by histopathologists to confirm the presence of ICC or CIN 2/3/AIS lesion and tested with short PCR fragment 10-DNA enzyme immunoassay-line probe assay for 14 oncogenic HPV types and 11 non-oncogenic HPV types. The prevalence of HPV 16, HPV 18, and other high-risk HPV types in ICC [including squamous cell carcinoma (SCC) and adenocarcinoma/adenosquamous carcinoma (ADC/ASC)] and CIN 2/3/AIS was estimated.
RESULTS: In the 5 Asian countries, diagnosis of ICC was confirmed in 500 women [SCC (n = 392) and ADC/ASC (n = 108)], and CIN 2/3/AIS, in 411 women. Human papillomavirus DNA was detected in 93.8% to 97.0% (84.5% for the Philippines) of confirmed ICC cases [94.0%-98.7% of SCC; 87.0%-94.3% (50.0% for the Philippines) of ADC/ASC] and in 93.7% to 100.0% of CIN 2/3/AIS. The most common types observed among ICC cases were HPV 16 (36.8%-61.3%), HPV 18 (12.9%-35.4%), HPV 52 (5.4%-10.3%), and HPV 45 (1.5%-17.2%), whereas among CIN 2/3/AIS cases, HPV 16 (29.7%-46.6%) was the most commonly observed type followed by HPV 52 (17.0%-66.7%) and HPV 58 (8.6%-16.0%).
CONCLUSIONS: This article presents the data on the HPV prevalence, HPV type distribution, and their role in cervical carcinogenesis in 5 Asian countries. These data are of relevance to public health authorities for evaluating the existing and future cervical cancer prevention strategies including HPV-DNA testing-based screening and HPV vaccination in these Asian populations.
STUDY DESIGN: In this cross sectional study, between November 2013 to March 2014, in a public university, a convenient sampling method was used. A total of 716 respondents were recruited and interviewed with a set of standard questionnaires for assessment of knowledge, perception and attitudes towards HPV and predictor variables associated with level of knowledge.
RESULTS: Almost half (48.9%) of the respondents scored less than 5 and were categorised as having poor knowledge. Three hundred and twelve (43.6%) respondents had moderate knowledge and only 54 (7.5%) respondents exhibited good knowledge with the score of 11 and above. Only 142 (20%) students perceived themselves to be vulnerable to HPV infection though 560 (78.2%) students thought that HPV infection is a serious disease. Perceived benefits and desire to be vaccinated were significantly associated with gender (p=0.000) and knowledge of HPV vaccine and cervical cancer (p=0.000).
CONCLUSIONS: The level of knowledge regarding HPV among the pre-university students was low. However, student intention for vaccination increased with increasing level of knowledge. Thus, efforts to improve knowledge and awareness should be prioritised to increase uptake of the HPV vaccination programme and hence reduce morbidity and mortality from consequences of HPV infection, including cervical carcinoma.
MATERIALS AND METHODS: Cervical scrapings were collected from women attending clinics for routine Pap smear screening. HPV-DNA was detected by PCR using MY09/11 and GP5+/GP6+ primer sets and genotyping was accomplished by cycle-sequencing.
RESULTS: A total of 635 women were recruited into the study with mean ± SD age of 43 ± 10.5 years. Of these 92.6% (588/635) were reported as within normal limits (WNL) on cytology. The presence of HPV infection detected by nested MY/GP+-PCR was 4.4% (28/635). The overall prevalence of high-risk HPV (HR-HPV) in abnormal Pap smears was 53.8% (7/13). HPVs were also seen in 3.1% (18/588) of smears reported as WNL by cytology and 5.9% (2/34) in smears unsatisfactory for evaluation.
CONCLUSIONS: The overall percentage of HPV positivity in routine cervical screening samples is comparable with abnormal findings in cytology. Conventional Pap smear 'missed' a few samples. Since HPV testing is expensive, our results may provide valuable information for strategising implementation of effective cervical cancer screening in a country with limited resources like Malaysia. If Pap smear coverage could be improved, HPV testing could be used as an adjunct method on cases with ambiguous diagnoses.
METHODOLOGY: A total number of 612 secondary school girls participated in this study. The questionnaire consists of 38 questions which included 3 sections. The first section is about socio- demography. The Second section is about knowledge and awareness of HPV vaccines. The third section is about practices with associated barriers of HPV vaccination. Verbal consent was obtained from all participants, and data were analyzed using SPSS 13.
RESULTS: A total number of 612 secondary school girl students participated in this study. The mean age was 13.93 ± SD (1.09); minimum age was 13 years old and maximum was 17 years old. The majority of them was Malay, from rural areas and had a family monthly income of RM 3000 or less (91.8%, 53.1%, 69.6%; respectively). The majority of the parents of the school girls were with secondary education level (56.4%). The majority of the participants did not have a family history of cervical cancer (99.0%). The prevalence of HPV vaccination was 77.9% among school girls in Melaka. The majority of the participants were vaccinated in their schools (77.0%). About 69% knew about cervical cancer and 77.6% had ever heard about HPV vaccine. Regarding the factors that influence the practice of uptake HPV vaccine, they were age, race, income, parents' education, knowledge about cervical cancer, heard about HPV vaccine and place of getting the vaccine (p<0.001).
CONCLUSION: The prevalence of HPV vaccine among school girls is high. Age, race, income, parents' education, knowledge about cervical cancer, heard about HPV vaccine and place of getting the vaccine were the significant factors that influence the practice of uptake HPV vaccine among school girls.
METHODOLOGY: This qualitative in-depth interview study was conducted in January 2010 with 30 university students from different faculties, i.e.:International Medical School (IMS), Faculty of Health and Life Sciences (FHLS), Faculty of Business Management and Professional Studies (FBMP) and Faculty of Information Sciences and Engineering (FISE) of the Management and Science University (MSU), Shah Alam, Malaysia. After consent was obtained from all participants, the interviewer wrote down the conversations during the interview sessions. The data obtained were classified into various categories and analyzed manually.
RESULTS: The majority of participants 25 (83%) had heard about cervical cancer, while 16 (53.3%) have never heard of HPV. Only five participants (17%) mentioned that HPV is the cause of cervical cancer. Ten participants (33.3%) did not know any causes. The majority 16 (53.3%) did not know the mode of HPV transmission. The majority of participants 22 (73.3%) mentioned that they had not been vaccinated against HPV. Out of 22, 16 (53.3%) agreed to be vaccinated in the future to protect themselves from cervical cancer and five (17%) participants mentioned they are not willing because of the uncertain safety of the available vaccines and their side effects.
CONCLUSION: This study showed relatively poor knowledge about HPV and its vaccines, pointing to urgency of educational campaigns aimed at students in the public and government universities to promote HPV vaccination among this highly eligible population.
