Stage 0 Rectal Cancer

Current Clinical Trials

Stage 0 rectal cancer is the most superficial of all rectal lesions and is limited to the mucosa without invasion of the lamina propria. Because of its superficial nature, surgical and other procedures may be limited.

Standard treatment options:

  1. Local excision or simple polypectomy.[1]
  2. Full-thickness rectal resection by the transanal or transcoccygeal route for large lesions not amenable to local excision.
  3. Endocavitary radiation therapy.[2-4]
  4. Local radiation therapy.[2]
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 rectal 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.
