Human papillomavirus (HPV) infection is recognized as one of the major causes of infection-related cancer in both men and women. High-risk HPV types are not only responsible for virtually all cervical cancer cases but also for a fraction of cancers of the vulva, vagina, penis, anus, and head and neck cancers. Furthermore, HPV is also the cause of anogenital warts and recurrent respiratory papillomatosis. Despite the availability of multiple preventative strategies, HPV-related cancer remains a leading cause of morbi-mortality in many parts of the world, particularly in less developed countries...

BACKGROUND: In Japan, the cervical cancer preventative HPV vaccination rate has dramatically declined, directly as a result of repeated broadcasts of so-called adverse events and the resulting suspension of the government's recommendation. Our previous survey of obstetricians and gynecologists in Japan regarding their opinions toward HPV vaccination revealed that these key specialists were as negatively influenced by the reports of purported negative events as were the general population...

In this hospital-based descriptive study, the genotype distribution of human papillomavirus (HPV) among HPV-infected women were investigated in 4,305 gynecological patients in Sichuan province. Females attending gynecology clinics between March 2014 and March 2015 were subjected to HPV screening after giving informed consent. Cervical scrapings were examined by cytopathology and colposcopy-directed biopsies. HPV genotyping was performed on a Luminex 200 system. Seventeen high-risk (HR) genotypes (HPV-16, -18, -31, -33, -35, -39, -45, -51, -52, -53, -56, -58, -59, -66, -68, -73, and -82) and seven low-risk (LR) genotypes (HPV-6, -11, -42, -43, -61, -81, and -83) were detected...

Human papillomavirus (HPV) is the key epidemiologic factor of cervical cancer, but additional cofactors are mandatory. Estrogen has been considered as one of those. Here, the aim was to study the effects of steroid hormones on HPV16 E6-E7, estradiol receptors ERα and ERβ, and progesterone receptor (PR) in HPV16-positive cervical carcinoma cell lines SiHa and CaSki grown as epithelial and fibroblast spheroid co-cultures. The spheroid co-cultures were exposured to 17β-estradiol or progesterone from day 7 onwards...

Persistent infection with high-risk human papillomavirus (HR-HPV) is necessary for the development of precursor lesions and cervical cancer. HPV infection among women living with HIV/AIDS (WLHA) occurs more frequently, presents a higher rate of persistent infections and an earlier progression to cancer. We aimed to evaluate HR-HPV prevalence, incidence and clearance, and its association with HIV viral suppression, immunological response and other risk factors among WLHA followed at an STD/HIV reference center...

The 9-valent human papillomavirus (9vHPV) vaccine covers the same HPV types (6/11/16/18) as the quadrivalent HPV (qHPV) vaccine and 5 additional cancer-causing types (31/33/45/52/58). Epidemiological studies indicate that the 9vHPV vaccine could prevent approximately 90% of cervical cancers, 70-85% of high-grade cervical dysplasia (precancers), 85-95% of HPV-related vulvar, vaginal, and anal cancers, and 90% of genital warts. Areas covered: Study design features and key findings from the 9vHPV vaccine clinical development program are reviewed...

Patti E Gravitt, Rachel L Winer
Large-scale epidemiologic studies have been invaluable for elaboration of the causal relationship between persistent detection of genital human papillomavirus (HPV) infection and the development of invasive cervical cancer. However, these studies provide limited data to adequately inform models of the individual-level natural history of HPV infection over the course of a lifetime, and particularly ignore the biological distinction between HPV-negative tests and lack of infection (i.e., the possibility of latent, undetectable HPV infection)...

Introduction Epidemiological studies indicate that diet rich in fruits and vegetables are associated with decreased cancer risk thereby indicating that dietary polyphenols can be potential chemo-preventive agents. The reversible nature of epigenetic modifications makes them a favorable target for cancer prevention. Polyphenols have been shown to reverse aberrant epigenetic patterns by targeting the regulatory enzymes, DNA methyltransferases (DNMTs) and histone deacetylases (HDACs). In vitro and in silico studies of DNMTs and HDACs were planned to examine genistein's role as a natural epigenetic modifier in human cervical cancer cells, HeLa...

Human papillomavirus type 16 (HPV16) is responsible for most cancers attributable to HPV infection and naturally occurring variants of the HPV16 E6 oncoprotein predispose individuals to varying risk for developing cancer. Population studies by us and others have demonstrated that the common Asian-American E6 (AAE6) variant is a higher risk factor for cervical cancer than the E6 of another common variant, the European prototype (EPE6). However, a complete understanding of the molecular processes fundamental to these epidemiological findings is still lacking...

Cervix carcinoma is the second commonest condition in women under 50 years of age and third after breast and oral cavity cancers across all age groups. Though a preventable disease, the mortality rate is very high because it is an ignored ailment in Pakistan in terms of screening, prevention and vaccination. More than 70% of cancer patients report with very advanced stage of malignancy and this is the cause of the high rate of mortality in Pakistan. We covered studies cited during the previous 11 years (2005-2015) that reviewed many aspects of cervical cancer in Pakistan, including epidemiology, risk factors, screening test and their barriers, clinical presentation and prevention...
