Anal Cancer Treatment (PDQ®)

Stage 0 Anal Cancer

Stage 0 anal cancer is carcinoma in situ. Rarely diagnosed, it is a very early cancer that has not spread below the limiting membrane of the first layer of anal tissue.

Standard treatment options:

Surgical resection is used for treatment of lesions of the perianal area not involving the anal sphincter (approach depends on the location of the lesion in the anal canal).

Current Clinical Trials

Check for U.S. clinical trials from NCI's list of cancer clinical trials that are now accepting patients with stage 0 anal cancer. The list of clinical trials can be further narrowed by location, drug, intervention, and other criteria.

General information about clinical trials is also available from the NCI Web site.
