Summary
Brief summary (as posted)
This phase II trial will investigate the combination of adjuvant 5-fluorouracil, radiation, and bevacizumab in patients with stage II and III rectal cancer, followed by FOLFOX6 and bevacizumab. Fluorouracil (FU) has proven to be an effective and safe regimen in the treatment of stage II and III rectal cancer. Recent evidence has proven fluorouracil/leucovorin (FL) in combination with bevacizumab is superior to FL alone and when combined with irinotecan is superior to (irinotecan plus fluorouracil/leucovorin (IFL) alone. This trial will be one of the first clinical trials to evaluate a combination of targeted therapy, radiation, and chemotherapy in the adjuvant treatment of a common solid tumor.

- Cohort A - Preoperative
- description
- Each patient enrolled in the preoperative cohort received 5-fluorouracil (5-FU) 225 mg/m2 as a continuous infusion (IVCI) on days 1-42 through a portable infusion pump and central venous catheter. Bevacizumab 5 mg/kg was administered intravenously (IV) on days 1 and 15. Additionally these patients received radiation therapy to 50.4 Gy (1.8 Gy/day or 28 fractions) Monday through Friday during weeks 1-6. At least 8 weeks after surgery, patients in cohort A began 4 months of chemotherapy and bevacizumab. This adjuvant treatment consisted of 5-FU 400 mg/m2 IV bolus over 2-4 minutes followed by 2400 mg/m2 IVCI over 46 hours, leucovorin 350 mg as a 2-hour infusion, oxaliplatin 85 mg/m2 IV (modified FOLFOX6) and bevacizumab 5 mg/kg IV all on days 1 and 15 of each cycle.

- All patients enrolled in cohort B received 5-fluorouracil (5-FU) 225 mg/m2 IVCI on days 1-42. Bevacizumab was administered at 5 mg/kg IV on day 1 every 2 weeks. These patients also received radiation to 50.4 Gy (1.8 Gy/day or 28 fractions)Monday through Friday during weeks 1-6. Six weeks after the completion of adjuvant 5-FU/radiation, patients began treatment with 5-FU 400 mg/m2 IV bolus over 2-4 minutes followed by 2400 mg/m2 IVCI over 46 hours, leucovorin 350 mg as a 2-hour infusion, oxaliplatin 85 mg/m2 IV (modified FOLFOX6) and bevacizumab 5 mg/kg IV all on days 1 and 15 of each cycle.
