Colon Cancer Treatment (PDQ®): Treatment - Health Professional Information [NCI] - Stage II Colon Cancer Treatment


Based on these data, the American Society of Clinical Oncology issued a guideline stating "direct evidence from randomized controlled trials does not support the routine use of adjuvant chemotherapy for patients with stage II colon cancer."[13]

Current Clinical Trials

Check for U.S. clinical trials from NCI's list of cancer clinical trials that are now accepting patients with stage II colon 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.
