Anal cytology screening for lesions among HIV-positive patients.
Anal carcinoma is relatively rare although its incidence is increasing, particularly among HIV-positive men who have sex with men Men who have sex with men (MSM) is a term used mostly in the United States to classify men who engage in sex with other men, regardless of whether they self-identify as gay, bisexual, or heterosexual. . Anal carcinoma shares many similarities with cervical cancer, and based on the cervical cancer screening programme, many experts have suggested that routine anal cytology cytology (sītŏl`əjē), in biology, the study of the structure of all normal and abnormal components of cells and the changes, movements, and transformations of such components. screening be performed on high-risk individuals to detect and remove pre-cancerous anal lesions. This study describes a routine anal cytology screening programme in an urban HIV-positive population in the US to determine risk factors for abnormal anal cytology and whether an association exists between abnormal cytology and histology.
49% of the 560 clinic patients were screened for two years, of whom 32% were women. 28% had abnormal anal cytology, and they were also more likely to have anal disease on perianal perianal

They were also more likely to be caucasian, homosexual or bisexual and have a lower CD4+ count. Routine anal cytology screening is a feasible tool to incorporate into routine HIV HIV (Human Immunodeficiency Virus), either of two closely related retroviruses that invade T-helper lymphocytes and are responsible for AIDS. There are two types of HIV: HIV-1 and HIV-2. HIV-1 is responsible for the vast majority of AIDS in the United States. care. Cytological abnormalities were found in patients without obvious risk factors, suggesting that all HIV-positive patients should have anal cancer screening. The follow-up for abnormal cytology represents the most difficult aspect of the programme, including getting patients to come for anoscopy. (1)
