Summary

Preoperative radiation and chemotherapy is the standard treatment for local advanced rectal cancer. The addition of oxaliplatin to capecitabine combined with radiotherapy does not improve local control and long-term survival. Most importantly,chemoradiotherapy significantly increased surgical complication and poor long-term quality of life .In the absence of effective measures of predicting chemo-sensitivity, there is considerable risk of using any two-drug regimen for neoadjuvant therapy. Simultaneous use of the three chemotherapeutic drugs may be able to reduce the likelihood of resistance to both dual drug regimen and single drug regimen. The purpose of this study is to compare the efficacy and safety of three chemotherapeutic regimen known as FOLFOXIRI (the drug 5-fluorouracil, oxaliplatin, Irinotecan) with standard radiotherapy combined with capecitabine in neoadjuvant therapy for local advanced rectal cancer. The drugs in the FOLFOXIRI regimen are all FDA(Food and Drug Administration) approved and have been used routinely to treat patients with advanced colorectal cancer.

Conditions

Interventions

DRUG

FOLFOXIRI

Irinotecan165 mg/m2、Oxaliplatin85 mg/m2、Left-calcium leucovorin 200mg/㎡，Intravenous infusion，first day. Then, 5-FU 1600 mg/m2/d×2 continuous intravenous infusion（total 3200 mg/m2，infusion 46 hours）in the next two days. Repeat every 14 days.

DRUG

XELOX

XELOX consisting of 130 mg/m2 oxaliplatin administered intravenously on day 1 and 1,000 mg/m2 capecitabine administered orally twice daily on days 1-14 for a 3-week cycle.

OTHER

Chemoradiotherapy

Chemotherapy: oral capecitabine（1650 mg/m2）twice daily during radiotherapy without weekend breaks. Radiation: Radiation therapy is administered via intensity-modulated radiation therapy (IMRT) with a linear accelerator, 6MV-X ray. The patients are scheduled to receive a GTV expanding 6mm to form PTV1 and CTV expanding 6mm to form PTV2. The dose of PTV1 is 50Gy/25 times for 35 days and the dose of PTV2 is 45Gy/25 times for 35 days. Patients were treated in consecutive days per week for a total of 5 weeks.
