Primary

MeasureTime frame
At baseline and each follow up: 1. The outcome of histopathological evaluation is into three groups: 1.1.HSIL (including Indefinite HSIL/LSIL), 1.2.LSIL, and 1.3.No Dysplasia (combining “no dysplasia in resected tissue” and “no lesions at index endoscopy”). 2. The outcome of HPV PCR is grouped into: 2.1.High-risk (Hr) HPV (including types 16 and 18), 2.2.Low-risk (Lr) HPV, and 2.3.No HPV (including cases with insufficient material). 3. The outcome of cytology evaluation is categorized as: 3.1.ASC-H, HSIL, Indefinite HSIL/LSIL, 3.2.ASCUS/LSIL, and 3.3.Benign (including Condyloma and insufficient material).

Secondary

MeasureTime frame
1. Pain is measured using visual analogue score (VAS) and Numerical Rating Scale (NRS) after anal sampling and endoscopy, in an anonymous questionnaire. NRS is used after endoscopy and documented. 2. The acceptability of flexible endoscopy of the anal canal and cytology and HPV testing measured using a questionnaire at each visit.
