Phase II Study: Hyperfractionated Pre-Op Chemo-Radiation for Locally Advanced Rectal Cancer

OBJECTIVES: I. Determine the local recurrence rate, disease-free survival, and overall
survival of patients with stage II or III rectal cancer treated with neoadjuvant
radiotherapy and fluorouracil followed by surgical resection and adjuvant fluorouracil and
leucovorin calcium. II. Determine the toxicity rate in patients treated with this regimen.
III. Correlate failure-free survival with ultrasound-determined preoperative staging in
patients treated with this regimen. IV. Determine the quality of life of patients treated
with this regimen. V. Determine if toxicity due to treatment, daily stool frequency, sexual
dysfunction, and disease-free survival correlates with quality of life parameters in
patients treated with this regimen. VI. Correlate clinical selection criteria with ability
to perform sphincter-sparing surgery in patients treated with this regimen. VII. Determine
post-chemoradiotherapy pathological response, margin status, and lymph node status and
correlate these factors with initial clinico-pathologic findings in patients treated with
this regimen.

OUTLINE: Patients undergo pelvic radiotherapy once daily five days a week for 5 weeks
followed by boost radiotherapy twice daily for 7 days. Patients also receive neoadjuvant
fluorouracil IV continuously over days 1-4 and 36-40. Patients undergo surgical resection
4-6 weeks after completion of radiotherapy. At 4 weeks after surgery, patients receive
adjuvant leucovorin calcium IV and fluorouracil IV once daily five days a week. Treatment
continues every 4 weeks for 4 courses in the absence of disease progression or unacceptable
toxicity. Quality of life is assessed at baseline, at the completion of pelvic and boost
radiotherapy, at 4 weeks after completion of chemoradiotherapy (prior to surgery), and then
at 3, 6, and 12 months after completion of study therapy. Patients are followed every 3
months for 2 years, every 4 months for 3 years, and then annually thereafter.

PROJECTED ACCRUAL: A total of 23-41 patients will be accrued for this study.
