Objectives

I.  Compare local recurrence rates, rates of distant metastasis, 
recurrence-free survival, and overall survival in patients having potentially 
curative resections of Dukes B2 and C rectal carcinoma treated either with 
postoperative radiation alone or with sequential chemotherapy using 
methyl-CCNU and 5-fluorouracil plus postoperative radiation.

Entry Criteria

Disease Characteristics:

See General Eligibility Criteria

Patient Characteristics:

See General Eligibility Criteria

General Eligibility Criteria:

Patients with histologically proven 
Dukes B2 or C adenocarcinoma of the rectum in whom a potentially curative 
resection has been performed with neither gross nor microscopic evidence of 
residual disease.  There may have been no prior chemotherapy nor radiotherapy 
to the pelvis.  Bone marrow function must be adequate and the patient must 
have recovered from the acute effects of surgery and be maintaining normal 
oral nutrition.  There may be no history of any malignant disease within the 
previous 5 years other than squamous or basal cell carcinoma of the skin or in 
situ carcinoma of the cervix.

Expected Enrollment

200 patients will be accrued.

Outline

Randomized study.
Arm I:  Radiotherapy.  Postoperative pelvic irradiation using supervoltage 
equipment (Co60 or linear accelerator).
Arm II:  Radiotherapy plus 2-Drug Combination Chemotherapy.  Radiotherapy as 
in Arm I; plus Methyl-CCNU, MeCCNU, NSC-95441; 5-Fluorouracil, 5-FU, NSC-19893.

Note: The purpose of most clinical trials listed in this database is to test new cancer treatments, or new methods of diagnosing, screening, or preventing cancer. Because all potentially harmful side effects are not known before a trial is conducted, dose and schedule modifications may be required for participants if they develop side effects from the treatment or test. The therapy or test described in this clinical trial is intended for use by clinical oncologists in carefully structured settings, and may not prove to be more effective than standard treatment. A responsible investigator associated with this clinical trial should be consulted before using this protocol.
