Condition: Rectal Cancer
MeSH terms: Rectal Neoplasms
Intervention: Radiation therapy; Oxaliplatin; Raltitrexed; levofolinic acid; 5-fluorouracil; Bevacizumab
Intervention description: Radiation therapy will be administered at the total dose of 45 Gy, given with five weekly fractions over a period of 5 weeks. The daily fraction dose will be 1.8 Gy; 100 mg/m2 on day 1 every 2 weeks for 3 cycles (for patients with resectable organ metastases (M1), an additional 2 cycles of chemotherapy will be given after radiation therapy); 2.5 mg/m2 on day 1 every 2 weeks for 3 cycles (for patients with resectable organ metastases (M1) , an additional 2 cycles of chemotherapy will be given after radiation therapy); 250 mg/m2 on day 2 every 2 weeks for 3 cycles (for patients with resectable organ metastases (M1), an additional 2 cycles of chemotherapy will be given after radiation therapy); 800 mg/m2 on day 2 every 2 weeks for 3 cycles (for patients with resectable organ metastases (M1), an additional 2 cycles of chemotherapy will be given after radiation therapy); will be given by intravenous infusion at the dose of 5 mg/kg concurrent with chemotherapy and radiotherapy every 2 weeks for 4 cycles from -14 days to start chemo-radiotherapy (classical schedule) or 4 days before the concurrent administration of chemotherapy and radiation therapy for 2 cycles if the number of TRG1 was not reached in the first stage (statistical design) with the classical schedule (for patients with resectable organ metastases (M1), one additional administration of bevacizumab will be given after radiation therapy)

Summary:

      The purpose of this study is to evaluate the use of chemotherapy, radiation therapy and
      bevacizumab before surgery in patients with locally advanced rectal cancer (LARC).

             rectal cancer (LARC) at high risk of recurrence (T4, N+, T3N0 with tumor located in
             the lower third of the rectum and/or circumferential resection margin (CRM) £5 mm), or
             LARC with resectable organ metastasis (M1).
