Abstract 11 In Myanmar, cervical cancer ranks as the first most frequent cancer among women aged between 15 to 44 years and Human Papillomavirus (HPV) vaccination program is not established yet. Information on HPV genotypes distribution in cervical cancer is crucial to predict the future impact of HPV vaccines. This study aimed to determine the HPV-DNA and genotypes among women with cervical pre-cancer and cancer in Myanmar. A cross-sectional descriptive study was performed in 169 women with cervical neoplasia during 2012 to 2014. After obtaining informed consent, cervical cells were collected from 134 women with cervical intraepithelial neoplasia (CIN) and 35 with squamous cell carcinoma (SCC) of the cervix attending Sanpya General Hospital, Yangon, and Central Women Hospital, Mandalay. HPV-DNA testing and genotyping was performed by polymerase chain reaction and restriction fragment length polymorphism (PCR-RFLP). HR-HPV was identified in CINI (39.3%), CINII (58.6%), CINIII (66.7%), and SCC (77.1%). Overall, the most common genotypes were HPV-16 (68.1%), followed by HPV-31 (16.5%), HPV-18 (7.7%), HPV-58 (6.6%), and HPV-35 (1.1%). Among SCC, HPV-16 was the most common genotype (66.7%) followed by HPV-18 (14.8%), HPV-31 (11.1%), HPV-35 (3.7%), and HPV-58 (3.7%). In CINI, the most common genotype were HPV-16 (69.7%) followed by HPV-31 (21.2%), HPV-18 (6.1%) and HPV-58 (3.0%). In CINII, HPV-16 was most commonly determined (52.9%) followed by HPV-31 (23.5%), HPV-58 (17.6%), and HPV-18 (5.9%). In CINIII, HPV-16 was also the most common genotype (85.7%) followed by HPV-31 (7.1%) and HPV-58 (7.1%). Vaccine preventable genotype, HPV-16 was the most common genotype in Myanmar. This study highlighted that the establishment of National HPV vaccination program is needed to reduce the incidence and mortality of cervical cancer in Myanmar.[Table: see text][Table: see text] AUTHORS' DISCLOSURES OF POTENTIAL CONFLICTS OF INTEREST: No COIs from the authors.

Abstract 12 A causal role for human papillomavirus (HPV) associated cancers of vulva, penile, and anus is supported by evidence from molecular and epidemiologic investigations. This study detected the oncogenic HPV genotypes in vulva cancers, penile cancers and anal cancers by a cross-sectional descriptive study in 2013. A total of 100 paraffin embedded biopsy tissues of histologically confirmed vulva cancers, penile cancers and anal cancers within past five years during 2008 and 2012 were studied. Those cases were 61 vulva cancers from Central Women Hospital, Yangon and 30 penile cancers and 9 anal cancers from Yangon General Hospital. HPV-DNA testing and genotyping were performed by polymerase chain reaction and restriction fragment length polymorphism (PCR-RFLP). Consensus sequence primer pairs within the E6 andE7 open reading were used to amplify oncogenic HPV genotypes (HPV-16,-18,-31,-33,-35,-52b,-58). Restriction enzymes were used for determination of specific HPV genotypes. HPV was identified in 36.1% of vulva cancers (22/61), 26.7% of penile cancers (8/30) and 44.4% of anal cancers (4/9). In vulva cancers, HPV-33 was the most common genotype (40.9%) followed by HPV-16 (31.8%), HPV-31 (22.7%), and HPV-18 (4.6%). In penile cancers, HPV-16 (62.5%) was the most common genotype followed by HPV-33 (25%) and HPV-18 (12.5%). Among anal cancers, the most frequent genotypes were HPV-16 (75%) and HPV-18 (25%). This study is the first report of evidence based oncogenic HPV genotypes in vulva cancers, penile cancers and anal cancers in Myanmar. This research provides the valuable information in understanding the burden of HPV associated cancers of the vulva, penile, and anus in Myanmar and the consideration of the effectiveness of prophylactic HPV vaccination in not only cervical cancer but also non-cervical cancers.

ABSTRACT: Introduction: Human papillomavirus (HPV) is considered a necessary causative agent for developing oropharyngeal, anal and cervical cancer. Among women in Ecuadorian population, cervical cancer ranks as the second most common gynecological cancer. Not many studies about HPV burden have been published in Ecuador, and genotypes distribution has not been established yet. The little data available suggest the presence of other genotypes different than 16 and 18. Objectives: In the present study, we attempt to estimate the prevalence of HPV 16, HPV 18 and other 35 genotypes among Ecuadorian women undergoing cervical cancer screening. The overall prevalence of HPV infection was also estimated. Methods: Routine cervical samples were analyzed using Linear Array(r) HPV Genotyping test (Roche). Results: A total of 1,581 cervical samples obtained from Ecuadorian women undergoing cervical cancer screening were included in this study. HPV DNA was detected in 689 cervical samples (43.58%). Of these samples, 604 (38.20%) were positive for a single HPV genotype, while another 85 (5.37%) samples were positive for multiple HPV types. Genotype 16 (5.50%) resulted in the most frequently detected type in both single and multiple infections. HPV 33 (4.55%) and HPV 11 (3.80%) occupied the second and the third place in frequency among all detected genotypes. Conclusions: Viral genotypes different from HPV 16 and HPV 18 are frequently detected among Ecuadorian women. The overall prevalence of HPV resulted higher than the one reported in other South American countries with a greater burden in the second and third decades of life.

Abstract Background The variation of human papillomavirus (HPV) genotypes shapes the risks of cervical cancer and these variations are not well defined in Africa. Nucleotide changes within the L1 gene, nucleotide variability, and phylogeny were explored in relation to HIV in samples from Botswana and Kenya. Methods A total of 98 HPV-positive cervical samples were sequenced to identify different HPV variants. Phylogenetic inferences were used to determine HPV genotypes and investigate the clustering of sequences between women living with HIV (WLWHIV) and -women not living with HIV (WNLWHIV). Results Out of 98 generated sequences, 83.7% (82/98) participants had high-risk(HR) HPV genotypes while 16.3% (16/98) had low-risk (LR) HPV genotypes. Among participants with HR-HPV genotypes, 47.6% (39/82) were coinfected with HIV. The prevalence of HR-HPV genotypes was statistically higher in the Botswana population compared to Kenya (p-value < 0.001). Multiple amino acid mutations were identified in both countries. Genetic diversity differed considerably among WLWHIV and WNLWHIV. The mean pairwise distances between HPV-16 between HIV and HIV/HPV as well as for HPV-18 were statistically significant. Six (6) new deleterious mutations were identified in the HPV genotypes based on the sequencing of the L1 region, HPV-16 (L441P, S343P), HPV-18 (S424P), HPV-45 (Q366H, Y365F), and HPV-84 (F458L). The majority of the patients with these mutations were co-infected with HIV. Conclusions Genomic diversity and different genomic variants of HPV sequences were demonstrated. Candidate novel mutations within the L1 gene were identified in both countries which can be further investigated using functional assays.

The natural history of cervical cancer is strongly related to the presence of human papillomavirus (HPV) infection, with its relationship with cervical cancer being a matter of concern. It is estimated that 70% of all cervical cancers worldwide are caused by HPV 16 and 18. Accordingly, the present study aimed to contribute to the identification of HPV subtypes circulating in a group of women of Manaus-Brazil.  Cervical samples were collected from 49 women, following the eligibility criteria of the study, and DNA was then extracted from the samples, which were analyzed for the presence of the virus in the genetic material through the polymerase chain reaction (PCR) using generic primers (GP05/06). Finally, identification of the viral subtypes was performed using specific primers for the detection of the main subtypes already examined (16 and 18). Positive HPV DNA was detected in 100% of the samples included in the study. Human papillomavirus 16 was the most prevalent subtype in the majority of lesions, accounting for 29 (59.2%) of the positive cases, and HPV 18 was detected in four (8.2%) women. In these 4 cases there was co-infection, with the presence of both HPV 18 and HPV 16. Therefore, 40.8% (20 cases) in which HPV DNA was detected presented infection with other subtypes of HPV not included in the study. This data has clinical implications related to cervical cancer prevention, as the current prophylactic HPV vaccines are only effective against high-risk HPV 16 and 18 subtypes.

High Risk Hpv

High risk human Papillomavirus (HPV) infections ultimately cause cervical cancer. Human Immunodeficiency Virus (HIV) infected women often present with multiple high-risk HPV infections and are thus at a higher risk of developing cervical cancer. However, information on the circulating high-risk HPV genotypes in Kenya in both HIV-infected and HIV-uninfected women is still scanty. This study is aimed at determining the phylogeny and the HPV genotypes in women with respect to their HIV status and at correlating this with cytology results. This study was carried out among women attending the Reproductive Health Clinic at Kenyatta National Hospital, a referral hospital in Nairobi, Kenya. A cross-sectional study recruited a total of 217 women aged 18 to 50 years. Paired blood and cervical samples were obtained from consenting participants. Blood was used for serological HIV screening while cervical smears were used for cytology followed by HPV DNA extraction, HPV DNA PCR amplification, and phylogenetic analysis. Out of 217 participants, 29 (13.4%) were HIV seropositive, while 68 (31.3%) were positive for HPV DNA. Eight (3.7%) of the participants had abnormal cervical cytology. High-risk HPV 16 was the most prevalent followed by HPV 81, 73, 35, and 52. One participant had cervical cancer, was HIV infected, and had multiple high-risk infections with HPV 26, 35, and 58. HPV 16, 6, and 81 had two variants each. HPV 16 in this study clustered with HPV from Iran and Africa. This study shows the circulation of other HPV 35, 52, 73, 81, 31, 51, 45, 58, and 26 in the Kenyan population that play important roles in cancer etiology but are not included in the HPV vaccine. Data from this study could inform vaccination strategies. Additionally, this data will be useful in future epidemiological studies of HPV in Nairobi as the introduction or development of new variants can be detected.

Objective. To estimate the prevalence and genotypes of high-risk human papillomavirus (HPV) focusing HPV 16, 18, 52, and 58 in Japan. Methods. Liquid-base cytology specimens were collected from Japanese women (n=11022), aged 14–98. After classifying cytodiagnosis, specimens were analyzed for HPV DNA by the multiplex polymerase chain reaction method, where 1195 specimens were positive for cervical smear, except adenomatous lesions. Result. HPV genotypes were detected in 9.5% of NILM and 72.2% of ASC-US or more cervical lesions. In positive cervical smears, HPV genotypes were HPV 52 at 26.6%, HPV 16 at 25.2%, HPV 58 at 21.8%, and HPV 18 at 7.1%. Most patients infected with HPV 16 were between 20–29 years old, decreasing with age thereafter. As for HPV 52 and 58, although the detection rate was high in 30- to 39-year-olds, it also was significant in the 50s and 60s age groups. Conclusion. In Japan, as a cause of abnormal cervical cytology, HPV52 and 58 are detected frequently in addition to HPV 16. In older age groups, HPV 52 and 58 detection rates were higher than that observed for HPV 16. After widespread current HPV vaccination, we still must be aware of HPV 52 and 58 infections.

Recently, there has been a steady growth of cervical cancer all over the world, especially in Russia. Patients with cervical cancer have become much younger. At the same time, the human papillomavirus is not only the main factor in the neoplastic process, but it is also one of the most common sexually transmitted infections in the world. The aim of the paper is to assess the prevalence and characteristics of human papillomavirus genotypes in patients with cervical intraepithelial neoplasia. Materials and Methods. During the periodic screening we examined 213 women of a reproductive age with HPV infection. All patients underwent liquid-based cytology and human papillomavirus genotyping by polymerase chain reaction. Results. We revealed that the prevalence of cervical intraepithelial neoplasia among women with papillomavirus infection was 80.3 % (n=171). According to human papillomavirus genotyping, HPV 16 (38 %) and HPV 33 (32 %) prevailed. We also observed positive high correlation between high-grade squamous intraepithelial lesions (HSIL) and HPV 18 (r=+0.759, p=0.001), a negative mean correlation between HPV 45 and low-grade squamous intraepithelial lesions (LSIL) (r=-0.643, p=0.002). A cohort of patients with severe intraepithelial cervical lesions demonstrated high viral load rates. Conclusion. According to the results obtained, we established the dominance of HPV 16 and HPV 33 genotypes in cervical intraepithelial neoplasia. There were significant differences between HSIL and LSIL patients with HPV 18 and HPV 45. There was also a correlation between an increase in the viral load with the severity of the pathological process. Keywords: human papillomavirus, intraepithelial cervical neoplasms, cervical cancer. В последние годы в мире, особенно в России, наблюдается неуклонный рост и «омолаживание» рака шейки матки. При этом вирус папилломы человека является не только основным фактором прогрессирования неопластического процесса, но и одной из наиболее распространенных инфекций, предаваемых половым путем, в мире. Цель. Оценить распространенность и характеристику генотипов папилломавирусной инфекции у пациенток с цервикальными интраэпителиальными неоплазиями. Материалы и методы. Проведено обследование 213 пациенток репродуктивного возраста с ВПЧ-инфекцией, пришедших на профилактический осмотр. Всем женщинам было выполнено цитологическое исследование жидкостным методом и генотипирование вируса папилломы человека методом полимеразной цепной реакции. Результаты. Распространенность цервикальных интраэпителиальных неоплазий среди женщин с папилломавирусной инфекцией составила 80,3 % (171 пациентка). Согласно данным генотипирования вируса папилломы человека превалировал 16-й (38 %) и 33-й типы (32 %). Выявлена положительная высокая корреляционная связь между цервикальными неоплазиями высокой степени онкогенного риска (HSIL) и 18-м типом ВПЧ-инфекции (r=+0,759 при р=0,001), отрицательная средняя корреляционная связь 45-го типа ВПЧ с низкой степенью онкогенного риска (LSIL) (r=-0,643 при р=0,002). Продемонстрированы высокие показатели вирусной нагрузки в когорте пациенток с тяжелыми внутриэпителиальными цервикальными поражениями. Выводы. По результатам полученных данных установлено доминирование 16-го и 33-го генотипов ВПЧ при цервикальных интраэпителиальных неоплазиях с наличием значимых различий между пациентами с HSIL и LSIL в отношении 18-го и 45-го типов, а также связь роста уровня вирусной нагрузки с увеличением степени тяжести патологического процесса.

In 1992 Lorincz et al. were the first to evaluate the clinicopathologic correlation with 11 recently identified human papillomavirus (HPV) genotypes: 31, 33, 35, 42, 43, 44, 45, 51, 52, 56, and 58. Using cervical samples from 8 studies that included specimens from 2627 women, HPV genotypes were categorized by the likelihood of association with grades of cervical neoplasia (from normal to cancer). These findings were the basis of the determination that (a) HPV causes cervical cancer, (b) detection of the cancer associated HPV genotypes could identify women at risk for cervical pre-cancer and cancer, and (c) a prophylactic HPV vaccine should include protection against (at least) HPV 16 and 18.

Abstract Background To estimate the prognostic relevance of human papillomavirus (HPV) 16 and HPV 18 in patients with cervical cancer. Method We searched PubMed, EMBASE, American Society of Clinical Oncology (ASCO) and the European Society of Medical Oncology (ESMO), CNKI, and Wanfang databases to search primary articles illustrating the survival outcomes in cervical cancer patients with or without HPV 16/18 infection. A meta-analysis was conducted to generate a combined hazard ratio (HR) with 95% confidence intervals (CI) for progression-free survival (PFS), disease free survival (DFS) and overall survival (OS). Results A total of 13 studies were included. Our meta-analysis revealed that HPV 16 positive did not have any impact on OS (HR, 0.76; 95% CI = 0.37–1.54; P = 0.44). Cervical cancer patiensts infected with HPV 18 had worse OS (HR, 1.66; 95% CI = 1.28–2.17; P = 0.0001), DFS (HR, 2.10; 95% CI = 1.73–2.54; P < 0.0001) and worse PFS (HR, 2.97; 95% CI = 1.69–5.23; P = 0.00012) compared with those not infected with HPV 18. cervical cancer patiensts infected with HPV 18 had worse PFS compared with those infected with HPV 16 ((HR, 1.34; 95% CI = 1.06–1.70; P = 0.01). Conclusion Cervical cancer patients infected with HPV 18 had worse survival compared with cervical cancer patients with HPV 16 infection.

The Cost

Background Human papillomavirus (HPV) vaccines and their widespread adoption have the potential to relieve a large part of the burden of cervical cancer morbidity and mortality, particularly in countries that have low screening rates or, like Japan, lack a cohesive universal screening program. An economic evaluation was conducted to assess the cost-effectiveness of introducing a bivalent HPV vaccination program in Japan from a healthcare perspective. Methods: A Markov model of the natural history of HPV infection that incorporates both vaccination and screening was developed for Japan. The modelled intervention, a bivalent HPV vaccine with a 100% lifetime vaccine efficacy and 80% vaccine coverage, given to a cohort of 12-year-old Japanese girls in conjunction with the current screening program, was compared with screening alone in terms of costs and effectiveness. A discount rate of 5% was applied to both costs and utilities where relevant. Results: Vaccination alongside screening compared with screening alone is associated with an incremental cost-effectiveness ratio (ICER) of US$20 315 per quality-adjusted-life-year gained if 80% coverage is assumed. The ICER at 5% coverage with the vaccine plus screening, compared with screening alone, is US$1158. Conclusion: The cost-effectiveness results suggest that the addition of a HPV vaccination program to Japan’s cervical cancer screening program is highly likely to prove a cost-effective way to reduce the burden of cervical cancer, precancerous lesions and HPV16/18-related diseases.
