Irinotecan-based combinations for the adjuvant treatment of stage III colon cancer

Abstract:
Irinotecan (Camptosar) is a topoisomerase I inhibitor with demonstrated antitumor activity against a wide variety of malignancies. Phase II studies have shown that this agent has significant single-agent activity against both chemotherapy-naive and fluorouracil (5-FU)-refractory colorectal cancer. Phase III studies now indicate that irinotecan/5-FU/leucovorin combinations have antitumor activity superior to standard 5-FU/leucovorin regimens alone. These irinotecan-based combinations are now entering clinical trials for the adjuvant treatment of resected stage III colon cancer. It is hypothesized that the superior antitumor activity of these irinotecan-based combinations seen in the metastatic setting will translate into improved survival and increased cure rates in these earlier-stage patients.
