Anal Pap smear : ウィキペディア英語版 | Anal Pap smear
An anal Pap smear is the anal counterpart of the cervical Pap smear. It is used for the early detection of anal cancer. Some types of human papillomavirus (HPV) can cause anal cancer. Other HPV types cause anogenital warts. Cigarette smokers, men who have sex with men, individuals with a history of immunosuppression (such as in HIV infection) and women with a history of cervical, vaginal and vulval cancer are at increased risk of getting anal cancer. Vaccination against HPV before initial sexual exposure can reduce the risk of anal cancer. == Indications == There is no consensus on who should get an anal Pap smear.〔 Some individuals recommend that all men and women who have anal sex should have an anal Pap smear performed regularly. Some recommend it for all men who have had sex with men, for all individuals with HIV and anal warts,〔 or for all individuals with a history of anal warts.〔 Cost-effectiveness studies have reported conflicting conclusions, due to incomplete understanding of the natural history of anal HPV infection and lack of clarity of the efficacy of interventions. An informal survey of local infectious-disease doctors in southeast Michigan suggested that few know where to send patients for an anal Pap smear. The procedure is very simple, and can be easily performed in any doctor's office with a little training.〔
