Radiation Therapy and Fluorouracil With or Without Combination Chemotherapy Followed by Surgery in Treating Patients With Stage II or Stage III Rectal Cancer - Full Text View

ClinicalTrials.gov Identifier:	NCT00335816

Purpose

RATIONALE: Radiation therapy uses high-energy x-rays to kill tumor cells. Drugs used in chemotherapy, such as fluorouracil, oxaliplatin, and leucovorin, work in different ways to stop the growth of tumor cells, either by killing the cells or by stopping them from dividing. Fluorouracil may also make tumor cells more sensitive to radiation therapy. Giving radiation therapy together with chemotherapy before surgery may make the tumor smaller and reduce the amount of normal tissue that needs to be removed.

PURPOSE: This phase II trial is studying how well giving radiation therapy together with fluorouracil with or without combination therapy works in treating patients who are undergoing surgery for stage II or stage III rectal cancer.

Detailed Description:

OBJECTIVES:

Determine the rate of pathologic complete response (i.e., no evidence of residual tumor in the resected specimen) in patients with stage II or III rectal cancer treated with neoadjuvant chemoradiotherapy comprising radiotherapy and fluorouracil with or without combination chemotherapy comprising oxaliplatin, leucovorin calcium, and fluorouracil followed by surgical resection.
Determine the effect of different chemoradiation-to-surgery intervals on the rate of pathologic complete response, surgical difficulty, and postoperative complications in these patients.

OUTLINE: This is a multicenter study. Patients are assigned to 1 of 4 treatment groups according to time of study enrollment.

Group 1: Patients undergo chemoradiotherapy comprising radiotherapy once daily 5 days a week for 5 weeks and fluorouracil (5-FU) IV continuously over 24 hours 7 days a week for 5 weeks (weeks 1-5). Patients undergo surgical resection of the rectum in week 12. Patients then receive 9 courses of FOLFOX-6 chemotherapy comprising oxaliplatin, leucovorin calcium, and 5-FU or other chemotherapy off study as directed by the physician.
Group 2: Patients undergo chemoradiotherapy as in group 1. Beginning in week 10, patients receive FOLFOX-6 chemotherapy comprising oxaliplatin IV over 2 hours and leucovorin calcium IV over 2 hours followed by bolus 5-FU on day 1 and 5-FU IV continuously over 46 hours on days 1 and 2. Treatment repeats every 14 days for 2 courses. Patients undergo surgical resection of the rectum in week 16. Patients then receive 7 additional courses of FOLFOX-6 chemotherapy or other chemotherapy off study as directed by the physician.
Group 3: Patients undergo chemoradiotherapy as in group 1. Beginning in week 10, patients receive FOLFOX-6 chemotherapy comprising oxaliplatin, leucovorin calcium, and 5-FU as in group 2. Treatment repeats every 14 days for 4 courses. Patients undergo surgical resection of the rectum in week 20. Patients then receive 5 additional courses of FOLFOX-6 chemotherapy or other chemotherapy off study as directed by the physician.
Group 4: Patients undergo chemoradiotherapy as in group 1. Beginning in week 10, patients receive FOLFOX-6 chemotherapy comprising oxaliplatin, leucovorin calcium, and 5-FU as in group 2. Treatment repeats every 14 days for 6 courses. Patients undergo surgical resection of the rectum in week 24. Patients then receive 3 additional courses of FOLFOX-6 chemotherapy or other chemotherapy off study as directed by the physician.

In all groups, treatment continues in the absence of disease progression or unacceptable toxicity.

After completion of study treatment, patients are followed for 1 month.

PROJECTED ACCRUAL: A total of 248 patients will be accrued for this study.
