“…Based on the complete reading of the 18 eligible papers for the systematic study [19][20][21][22][23][24][25][26][27][28][29][30][31][32][33][34][35][36] , it was found that the location where HPV is most predominant is the cervical area, the vulva, the vagina, and the anus, since they are associated with chronic infections, preceded by non-malignant precursor lesions, like the cervical squamous intraepithelial lesion (CSIL) and the anal squamous intraepithelial lesions (ASIL), with predilection being shown for the zone of cellular transition of glandular squamous cells, seeing that both have common biological characteristics, including histopathological aspects.…”

Introduction:Colorectal cancer is one of the most prevalent types of tumors worldwide. Deaths caused by these malignant tumors remain high and have stayed practically at the same level for the last few decades. Among the established risk factors for the development of cancer are infections due to pathogens or viruses. Among the viruses, the human papillomavirus (HPV) is the most prevalent, with over 180 strains, 40 of which are directly related to anogenital infections. Objective: Systematically assess the main studies which link HPV to colorectal cancer with meta-analysis. Methods: The search strategy adopted was the logic based on specific descriptors (English language), in combination with the Boolean operators (AND/OR). The search was conducted in the following databases: PubMed, ScienceDirect, and Scientific Electronic Library Online (SciELO), between April and May 2015. Results: 1,549 samples were assessed, with 956 (61.7%) being males. Six hundred thirty out of 1,358 cases of colorectal cancer due to HPV were diagnosed (51.9%). From these, 408 of 767 (51.9%) were male and 404 of 598 (67.5%) were linked to HPV 16 and 18, with tumor prevalence in the area of the cervix (253 of 411; 61.3%). From the total of 598 samples for the prevalence estimate of HPV 16 and 18, the number of cases with similar numbers was 204 (31.7%) and 200 (35.8%), respectively. Relatively significant numbers were found in the area of the cervix, 253 (61.3%), and the area of the rectum, 158 (38.7%). Conclusion: After conducting the present study, the link between HPV and colorectal cancer was made evident, without a distinction between the sexes, with similar values between HPV 16 and HPV 18.

“…19 In addition, self-reported current STI symptoms was highly correlated with increased risk of having visible anogenital warts, consistent with other studies reporting a greater likelihood of HPV infection with clinically diagnosed STIs. 24,28 Older age at first episode of anal intercourse was strongly correlated with having visible anogenital warts. This could be due to several factors including improved safe-sex education among younger MSM, lower frequency of anal intercourse acts among those younger than 14 years compared with older MSM, or the development of HPV-specific immunity due to early exposure among those with earlier sexual debut.…”

“…23 Although data on HPV prevalence in these populations are scarce, a recent study of 105 MSM recruited from an urban STI clinic found that 77.1% tested positive for HPV by polymerase chain reaction on anorectal samples. 24 In this crosssectional study, we examined factors associated with visible anogenital warts (overall and by anatomical site), including those that are known to confer increased risk for HIV infection, among HIV-uninfected MSM and transwomen in Lima, Peru.…”

“…One study of 105 MSM from an inner-city STI clinic in Lima found that 77.1% were infected with anogenital HPV and 43% were infected with a carcinogenic type; high-risk HPV type infection was associated with sex work, HIV status and rectal chlamydial or gonorrhoeal infection. 24 Another study of HPV prevalence among 200 Peruvian MSM found the seroprevalence of HPV types 6/11/16/18-for which the quadrivalent HPV vaccine confers protectionwas 64.3% and 93.8% for HIV-negative and HIV-positive MSM, respectively. 25 While both studies included information related to sexual practices, identity and roles, the analyses conducted do not allow side-by-side comparisons of these factors and HPV, information which could inform HPV surveillance, prevention and treatment for Latino MSM.…”

HPV knowledge, burden and genital wart location among heterosexually identified versus homosexually identified men who have sex with men in Lima, Peru: cross-sectional results from a cohort study

ObjectivesThe relationship between sexual practices, identity and role among Latino men who have sex with men (MSM) and HIV risk is the subject of ongoing investigation but less is known about how these aspects of sexuality relate to human papilloma-virus (HPV), an independent risk factor for HIV. This observational study investigated the relationship between HPV and sexual practices, identity and role as well as other sexually transmitted infection (STI)/HIV risk factors among HIV-negative heterosexually and homosexually identified Peruvian MSM.SettingCommunity-based clinic for MSM in Lima, Peru.Participants756 subjects were screened based on inclusion criteria of: born anatomically male; age ≥18 years; had any anal intercourse with a man during the previous 12 months; residing in metropolitan Lima; HIV negative; willing to commit to twice-yearly clinic visits for 24 months; had not participated in an HIV or HPV vaccine study. 600/756 participants met the inclusion criteria and were enrolled, of whom 48% (284) identified as homosexual and 10% (57) as heterosexual, the basis of the analyses performed.ResultsCompared with homosexually identified MSM, heterosexually identified MSM had completed fewer years of formal education and were less likely to have: anogenital HPV or visible anal warts; given oral sex to a man; or used a condom with their most recent female sexual partner (all p<0.05). Conversely, heterosexually identified MSM were more likely to have: visible penile warts; used a condom during last anal intercourse; smoked cigarettes; had transactional sex; and used drugs during sex in the previous month (all p<0.01). There was no difference found between heterosexually and homosexually identified MSM by syphilis or high-risk HPV prevalence.ConclusionsHPV burden, wart type (penile vs anal) and select HIV/STI risk behaviours differed between heterosexually and homosexually identified Peruvian MSM. Understanding the implications of these differences can lead to tailored HIV/STI prevention interventions for heterosexually identified MSM.Trial registration number NCT01387412.
