The incidence of anal cancer has increased among HIV-infected patients in France since 1996. Although an ascertainment bias cannot be excluded, data indicate that combination antiretroviral therapy does not prevent anal cancer in these patients. This supports the urgent need for developing anal cancer screening programs for HIV-infected men who have sex with men.

Anal incontinence after delivery is multifactorial, and anal sphincter defects account for only 45 percent of them. Primiparous and secundiparous patients have the same risk factors for sphincter disruption and anal incontinence. Because external anal sphincter disruptions are more frequent than internal anal sphincter damage, surgical repair should be discussed in symptomatic patients.

The EUROGIN 2011 roadmap reviews the current burden of HPV (human papillomavirus)-related morbidity, as well as the evidence and potential practice recommendations regarding primary and secondary prevention and treatment of cancers and other disease associated with HPV infection. HPV infection causes approximately 600,000 cases of cancer of the cervix, vulva, vagina, anus and oropharynx annually, as well as benign diseases such as genital warts and recurrent respiratory papillomatosis. Whereas the incidence of cervical cancer has been decreasing over recent decades, the incidence of anal and oropharyngeal carcinoma, for which there are no effective screening programs, has been rising over the last couple of decades. Randomised trials have demonstrated improved efficacy of HPV-based compared to cytology-based cervical cancer screening. Defining the best algorithms to triage HPV-positive women, age ranges and screening intervals are priorities for pooled analyses and further research, whereas feasibility questions can be addressed through screening programmes. HPV vaccination will reduce the burden of cervical precancer and probably also of invasive cervical and other HPV-related disease in women. Recent trials demonstrated that prophylactic vaccination also protects against anogenital HPV infection, ano-genital intraepithelial lesions and warts associated with vaccine types, in males; and anal HPV infection and anal intraepithelial neoplasia in MSM. HPV-related oropharyngeal cancer could be treated less aggressively because of better survival compared to cancers of the oropharynx unrelated to HPV. Key findings in the field of cervical cancer prevention should now be translated in cost-effective strategies, following an organised approach integrating primary and secondary prevention, according to scientific evidence but adapted to the local situation with particular attention to regions with the highest burden of disease.

Anal cancer is a rare cancer but its incidence is increasing. Human papillomavirus (HPV) infection seems to be associated with the occurrence of most cases. The genotype-specific prevalence of HPV in anal cancer was estimated to assess the potential benefit of HPV vaccination in France. Anal cancer histological specimens were retrospectively recruited in 2008 from 16 French centres and centrally tested for HPV genotyping using the INNO-LiPA assay allowing the detection of 28 genotypes. Results were analyzed according to age, gender, HIV status when available and histological diagnosis. A total of 366 anal cancer cases were analyzed among which 62% were females. Mean age at diagnosis was 54.8 years in males and 66.4 years in females (p < 0.001). HPV was found in 96.7% of cases, 72% being infected by a single HPV type. Presence of at least one high-risk genotype was observed in 91% of cases (96% in females and 83% in males; p < 0.001). HPV16 was by far the most prevalent genotype (75%), followed by HPV18, HPV52, HPV33, and HPV51 (4-6%). HPV16/18 alone or in association were found in 78% of all cases. HIV-positive cases had a higher proportion of multiple HPV infection than HIV-negative cases and a slightly different HPV type distribution with an under-representation of HPV16 and an over-representation of other types. Our results indicate that anal cancer rarely occurs in the absence of HPV and emphasize the predominant role of HPV16. The potential benefit of HPV vaccine on the occurrence of anal cancer should be further evaluated.

One third of females have thrombosed external hemorrhoids or anal fissures in the postpartum period. The most important risk factor is dyschezia. Traumatic delivery appears to be associated with thrombosed external hemorrhoids.

The high rate of condyloma and histological dysplasia seen argues for a systematic screening for these lesions in HIV-infected individuals.

Relative to that in the general population, the risk of anal cancer in HIV-infected patients is still extremely high, even in patients with high current CD4 cell counts. cART appears to have no preventive effect on anal cancer, particularly in MSM.

Cancer patients taking opioids for pain are very frequently constipated, even if they are prescribed laxatives. This leads to relevant impairments of quality-of-life.
