Adjuvant Therapy for Stage II Colon Cancer
Name of the Trial
Why This Trial Is Important
In this trial, researchers are using molecular tests to help identify patients who are at high risk for recurrence after colon cancer surgery. Those deemed at high risk will receive adjuvant chemotherapy (drug therapy given after surgery to help suppress cancer recurrence). Half of the high-risk patients will also receive adjuvant treatment with bevacizumab, a monoclonal antibody that blocks the activity of a protein called vascular endothelial growth factor (VEGF). Tumors often produce large quantities of VEGF, which stimulates the growth of new blood vessels that help provide nourishment. Blocking VEGF may inhibit this new blood vessel growth and prevent continued tumor growth. Patients at low risk for recurrence will not receive adjuvant therapy but will continue to be monitored.
"Because patients with stage II colon cancer generally have good survivorship, it is hard to measure the impact of adjuvant therapy for these patients," said Dr. Benson. "This is one of the largest trials for patients with stage II colon cancer ever conducted, so we hope to determine conclusively whether or not adjuvant therapy is helpful. Additionally, this trial is the first of its kind to use molecular tests to determine how patients will be treated after surgery."
