Summary

The purpose of this study was to evaluate the effect of concurrent capecitabine-based long-term radiotherapy followed by 4 cycles XELOX pre- a delayed TME compared with 6 cycles XELOX post- a Regular Timing TME in patients with high-risk rectal cancer defined by MRI.

Detailed description

This is the randomized controlled, multi-centers, and open-labeled study. Delivering systemic chemotherapy between concurrent capecitabine-based long-term radiotherapy and total mesorectal excision (TME) surgery would be more effectively improved local control rates and improved metastases-free survival rates. The investigators attempted to investigate the effect on pathological response of delivering 4 cycles XELOX between concurrent capecitabine-based long-term radiotherapy and TME with lengthening the interval from radiation to surgery. In this study, the participants with high risk of deeper infiltration, or extramural vessel invasion, or circumferential resection margin involvement, or surrounding organs and structures invaded et al. were recruited. The participants will be randomized (1:1 ratio) to a control and intervention arm. The participants in the control arm will receive best current practice of concurrent capecitabine-based long-term radiotherapy followed by TME and then a 6 cycles of XELOX as standard adjuvant chemotherapy. The participants in the intervention arm will receive concurrent capecitabine-based long-term radiotherapy followed by 4 cycles XELOX as neoadjuvant chemotherapy pre- a delayed TME.

Conditions

• Rectal Cancer

Interventions

Type	Name	Description
DRUG	concurrent capecitabine-based long-term radiotherapy followed by 4 cycles XELOX and a delayed TME	concurrent capecitabine-based long-term radiotherapy: capecitabine 825mg/m2,bid,d1-5, q week with Radiation treatment. Radiation treatment was given at 1·8 Gy per day, 5 days per week for 5-6 weeks, after a 45 Gy radiation dose in 25 fractions to the pelvis, a boost dose of 5·4 Gy in 3 fractions to the tumor bed or concurrent boosted. XELOX: Oxaliplatin: 130mg/m2,IV,d1; Capecitabine: 1000mg/m2,bid,d1-14; repeated every 3 weeks Surgery Procedure: Total Mesorectal Excision
