Phase 2 |
Detailed Description
The aim of this study is to investigate whether combined fruquintinib、toripalimab and SRT can achieve breakthrough efficacy in neoadjuvant therapy for locally advanced rectal cancer, achieving a better pCR rate and better tolerance compared with conventional neoadjuvant therapy for locally advanced rectal cancer.

Outcome Measures
Primary Outcome Measures
- pCR following neoadjuvant chemotherapy [approximately 2 weeks after the resection of primary lesion]
Pathologic complete response (pCR) rate defined as number of participants out of total that had no residual invasive disease (malignant cells)
Secondary Outcome Measures
- R0 resection rate [approximately 2 weeks after the resection of primary lesion]
number of R0 surgery divide all participants (44pts)
- Objective response rate [approximately before the resection of primary lesion]
Objective tumour response (ORR) will is defined as the proportion of subjects who achieve a partial or complete response according to RECIST criteria version 1.1
- 1 year DFS(disease free survival) rate [1 year]
evaluate the 1-year DFS rate after the resection of primary lesion（only patients who acquire R0 resection）
- 1 year OS(overall survival) rate [1 year]
evaluate the 1-year OS rate after the neoadjuvant therapy
