Practice parameters for anal squamous neoplasms.
How many Ain 1 patients progressed to cancer?
Not one of 17 patients with AIN 1 progressed to cancer during the follow-up period. Twenty-five patients downgraded their lesions. The authors suggest that since 13% of their AIN 3 patients converted to cancer during the follow-up period, it is necessary to keep all AIN 3 under close surveillance.
