Malignancy
NO
To assess the prevalence and progression of anal canal dysplasia and squamous cell carcinoma in men who have sex with men (MSM).
Others
In the previous study, we conducted an annual anal cytology examination for MSM, and conducted an HPV cohort study for early detection of precancerous lesions and cancer caused by anal HPV infection. In this study, we will evaluate the presence or absence of early cancer, and the degree of progression of precancerous lesions (AIN1 to 3) by HRA in MSMs with abnormal findings on anal cytology. Patients with precancerous lesions should be followed up for HRA every 1-2 years. We will evaluate the prevalence and progression of anal and precancerous lesions.

HRA histological diagnosis will show the degree of anal intra-epitherial neoplasia (AIN) (grade 1-3) and prevalence of anal canal cancer
Rate of change in the degree of anal intra-epitherial neoplasia (AIN) (1 to 3) after histological diagnosis by HRA

Prevention
| Device,equipment | Maneuver |
We will evaluate the presence or absence of early cancer, and the degree of progression of precancerous lesions (AIN1 to 3) by HRA in MSMs with abnormal findings on anal cytology. Patients with precancerous lesions should be followed up for HRA at least annually for 2 years.

Male
1) Persons who have obtained written consent for participation in the research
2) MSM whose age at the time of obtaining consent is 20 years or older
3) Persons diagnosed with precancerous lesions as defined below by anal scraping cytology
Definition of precancerous lesions: Low grade squamous intraepithelial lesion (LSIL), atypical squamous cells, cannot exclude HSIL (ASC-H), high grade squamous intraepithelial lesion (HSIL), or atypical squamous cells of undetermined significance (ASC-US) with positive high-risk anal HPV
1) Those who are allergic to local anesthesia
2) Those who are judged by the principal researcher to be inappropriate for inclusion in the research
