Despite surgery and conventional chemotherapy, a significant number of patients develop cancer recurrences and many go on to die from the cancer. For this reason, investigators continue to look for new cancer treatments and approaches. The study under consideration proposes to give colon cancer patients an anti-cancer therapy for 3 weeks before and for 3 weeks after undergoing operation to remove the colon cancer. This time period is referred to as the "perioperative period." Presently, around the world, doctors do not administer any type of anti-cancer therapy during the perioperative period. It is the belief of the investigators carrying out this study that this period may be an ideal time to fight the tumor and that treatment given during this time may improve survival and reduce cancer recurrence rates. Patients who choose to receive this biologic anti-cancer treatment immediately before and after surgery can also receive conventional chemotherapy at the usual time (4-6 weeks after surgery). Thus, this perioperative anti-cancer treatment would not interfere with the standard chemotherapy regimens used today.
