Cervical determinants of anal HPV infection and high-grade anal lesions in women: a collaborative pooled analysis

Cervical cancer screening might contribute to the prevention of anal cancer in women. We aimed to investigate if routine cervical cancer screening results-namely high-risk human papillomavirus (HPV) infection and cytohistopathology-predict anal HPV16 infection, anal high-grade squamous intraepithelial lesions (HSIL) and, hence, anal cancer.International Agency for Research on Cance

Anal cytology in women with cervical intraepithelial or invasive cancer: interobserver agreement

ABSTRACTIntroduction:Incidence rates of anal cancer have been rising worldwide in the last 20 years. Due to embryological, histological and immunohistochemical similarities between the anal canal and the cervix, routine screening with anal cytology for precursor lesions in high-risk groups has been adopted. Objective: To determine interobserver agreement for the diagnosis of anal neoplasia by anal cytology.Material and methods:A cross-sectional observational study was conducted in 324 women with cervical intraepithelial or invasive cancers, for screening of anal cancer, from December 2008 to June 2009. Three hundred twenty-four cytological samples were analyzed by three cytopathologists. Cytological evaluation was based on the revised Bethesda terminology; samples were also classified into negative and positive for atypical cells. We calculated the kappa statistic with 95% confidence interval (95% CI) to assess agreement among the three cytopathologists.Results:Interobserver agreement in the five categories of the Bethesda terminology was moderate (kappa for multiple raters: 0.6). Agreement among cytopathologists 1, 2 and 3 with a consensus diagnosis was strong (kappa: 0.71, 0.85 and 0.82, respectively).Conclusion:Interobserver agreement in anal cytology was moderate to strong, indicating that cervical cytomorphological criteria are reproducible also in anal samples

Tumor necrosis factor (TNF) alpha and interleukin (IL) 18 genes polymorphisms are correlated with susceptibility to HPV infection in patients with and without cervical intraepithelial lesion

9siThe Human Papillomavirus (HPV) predisposes 500 000 women to cervical cancer. Host genetic background may facilitate virus persistence in the uterine cervix. Polymorphisms in regulatory and coding regions of cytokine genes have been associated with susceptibility to some human diseases.reservedmixedMansur Tavares, Mayara C.; de Lima Junior, Sergio F; Coelho, Antonio V.

Cervical determinants of anal HPV infection and high-grade anal lesions in women : a collaborative pooled analysis

Background: Cervical cancer screening might contribute to the prevention of anal cancer in women. We aimed to investigate if routine cervical cancer screening results—namely high-risk human papillomavirus (HPV) infection and cytohistopathology—predict anal HPV16 infection, anal high-grade squamous intraepithelial lesions (HSIL) and, hence, anal cancer. Methods: We did a systematic review of MEDLINE, Embase, and the Cochrane library for studies of cervical determinants of anal HPV and HSIL published up to Aug 31, 2018. We centrally reanalysed individual-level data from 13 427 women with paired cervical and anal samples from 36 studies. We compared anal high-risk HPV prevalence by HIV status, cervical high-risk HPV, cervical cytohistopathology, age, and their combinations, using prevalence ratios (PR) and 95% CIs. Among 3255 women with anal cytohistopathology results, PRs were similarly calculated for all anal HSIL and HPV16-positive anal HSIL. Findings: Cervical and anal HPV infections were highly correlated. In HIV-negative women, anal HPV16 prevalence was 41% (447/1097) in cervical HPV16-positive versus 2% (214/8663) in cervical HPV16-negative women (PR 16·5, 95% CI 14·2–19·2, p<0·0001); these values were 46% (125/273) versus 11% (272/2588) in HIV-positive women (4·4, 3·7–5·3, p<0·0001). Anal HPV16 was also associated with cervical cytohistopathology, with a prevalence of 44% [101/228] for cervical cancer in HIV-negative women (PR vs normal cytology 14·1, 11·1–17·9, p<0·0001). Anal HSIL was associated with cervical high-risk HPV, both in HIV-negative women (from 2% [11/527] in cervical high-risk HPV-negative women up to 24% [33/138] in cervical HPV16-positive women; PR 12·9, 95% CI 6·7–24·8, p<0·0001) and HIV-positive women (from 8% [84/1094] to 17% [31/186]; 2·3, 1·6–3·4, p<0·0001). Anal HSIL was also associated with cervical cytohistopathology, both in HIV-negative women (from 1% [5/498] in normal cytology up to 22% [59/273] in cervical HSIL; PR 23·1, 9·4–57·0, p<0·0001) and HIV-positive women (from 7% [105/1421] to 25% [25/101]; 3·6, 2·5–5·3, p<0·0001). Prevalence of HPV16-positive anal HSIL was 23–25% in cervical HPV16-positive women older than 45 years (5/20 in HIV-negative women, 12/52 in HIV-positive women). Interpretation: HPV-based cervical cancer screening programmes might help to stratify anal cancer risk, irrespective of HIV status. For targeted secondary anal cancer prevention in high-risk groups, HIV-negative women with cervical HPV16, especially those older than 45 years, have a similar anal cancer risk profile to that of HIV-positive women.
