Efficacy and Safety Study of Neoadjuvant in Treating Patients With Resectable Local Recurrent Rectal Cancer

Sun Yat-sen University360 enrolled

Overview

RATIONALE: Surgical resection and adjuvant therapy has become the main treatment for resectable local recurrent rectal cancer. However the efficacy and safety of adjuvant therapy is still unknown. PURPOSE: This randomized multicenter clinical trial is studying surgical resection followed by chemo radiotherapy or neoadjuvant chemo radiotherapy followed by surgery and postoperative chemotherapy, comparing them to see the efficacy and safety, then to investigate the effect of adjuvant chemoradiotherapy for resectable local recurrent rectal cancer.

OBJECTIVES: Primary \- Compare the 5-year survival rate in patients with resectable local recurrent rectal cancer treated with either surgical resection or neoadjuvant. Secondary * Compare the side effect of chemo radiotherapy according to the Common Toxicity Criteria(CTC) version 2.0 in patients treated with these regimens. * Compare the postoperative complications in patients treated with these regimens. * Compare the recurrent rate in patients treated with these regimens. * Compare the distant metastatic rate in patients treated with these regimens. OUTLINE: This is a randomized, multicenter clinical trial. Patients are stratified according to participating center, gender, age. Patients are randomized to 1 of 2 treatment arms. * Arm I: Patients receive surgical resection and undergo FOLFIRI for 12 cycles, from 2-4 weeks after operation. Patients undergo radiotherapy once daily 5 days a week for 5-6 weeks, from 8-12 weeks after operation. * Arm II: Patients receive neoadjuvant chemoradiotherapy (mFOLFIRI for 5 cycles and undergo radiotherapy as in arm I from the second cycle of FOLFIRI), surgery and FOLFORI for 7 cycles from 2-4 weeks after operation. After completion of study treatment, patients are followed every 3 months for 2 years, and then every 6 months for at least 3 years. The side effect of chemo radiotherapy, postoperative complications, recurrent rate, distant metastatic rate and 5-year survival rate will be investigated. PROJECTED ACCRUAL: A total of 360 patients will be accrued for this study within 5 year.
