Purpose
RATIONALE: Drugs used in chemotherapy use different ways to stop tumor cells from dividing so they stop growing or die. Radiation therapy uses high-energy x-rays to damage tumor cells. It is not yet known which treatment regimen is more effective for rectal cancer.
PURPOSE: Randomized phase III trial to compare the effectiveness of different regimens of combination chemotherapy plus radiation therapy in treating patients who have rectal cancer that has been surgically removed.

Detailed Description:
OBJECTIVES: I. Compare the overall and relapse free survival of patients with stage II or III rectal cancer treated with one of the following three regimens: bolus injections of fluorouracil (5-FU) prior to and following pelvic irradiation plus protracted venous infusion (PVI) 5-FU radiosensitization vs PVI 5-FU prior to and following pelvic irradiation plus PVI 5-FU radiosensitization vs bolus 5-FU with leucovorin calcium and levamisole prior to and following pelvic irradiation. II. Describe relapse patterns and tolerance associated with these regimens in these patients.
OUTLINE: This is a randomized, multicenter study. Patients are stratified according to type of prior surgery (abdominoperineal resection vs anterior resection), nodal status (N0 vs N1 vs N2-3), depth of tumor invasion (T1-2 vs T3 vs T4a vs T4b), time from surgery to study entry (20-45 days vs 46-70 days), participating center, and performance status (0-1 vs 2). Patients are randomized to one of three treatment arms. Arm I: Patients receive fluorouracil (5-FU) IV on days 1-5 and 29-33. 5-FU is then given as a continuous infusion beginning on day 57 and continuing concurrently with radiotherapy for 5 weeks. Following a 28 day break from treatment patients receive 5-FU IV on days 1-5 of a 28 day course. Postradiotherapy treatment repeats for a total of 2 courses in the absence of disease progression or unacceptable toxicity. Arm II: Patients receive 5-FU IV continuously on days 1-42. 5-FU and radiotherapy are then administered as in arm II. Arm III: Patients receive leucovorin calcium (CF) IV followed by 5-FU IV on days 1-5 and 29-33. Patients also receive oral levamisole twice daily on days 1-3, 15-17, 29-31, and 43-45. CF IV and 5-FU IV are then given on days 57-60 and 85-88 concurrently with radiotherapy. Following a 28 day break from treatment patients receive CF IV and 5-FU IV on days 1-5 and 29-33 and oral levamisole twice daily on days 1-3, 15-17, 29-31, and 43-45 in the absence of disease progression or unacceptable toxicity. All patients receive radiotherapy 5 days per week for 5 weeks starting on day 57. Patients are followed every 4 months for 2 years, then every 6 months for 4 years, and then annually until death.
PROJECTED ACCRUAL: A total of 1,800 patients (600 per arm) will be accrued for this study.
