Clinical Trial Summary

In this study, a randomized controlled trial was conducted on advanced colon cancer patients with preoperative tumor staging T1-4/N1-2/M0 or T4/N0/M0 to determine the effectiveness of preoperative short-term radiotherapy combined with chemotherapy and whether it can effectively reduce the postoperative local recurrence rate, so as to provide better treatment for colon cancer patients and improve the oncological treatment effect of colon cancer.

Description:

This is prospective,a single-arm, single center, clinical trail study.The patient entered the study after meeting that criteria.The ORR, R0 resection, OS and DFS of patients and neoplasm down-staging status,etc would be compared.

• Colonic Neoplasms

Intervention

Radiation:
• Short-term neoadjuvant chemoradiotherapy
Short-term radiotherapy ( 25 Gy, 5f ) + XELOX regimen was performed before operation for two cycles. After the condition was evaluated by enhanced CT, whether the patients belonged to PD, SD, PR and CR was analyzed (reference RECIST 1.1). Surgery was performed four weeks after chemotherapy.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Investigate patients ORR	Investigate patients ORR(objective response rate ) include CR(complete response) and PR(partial response)	7 days after surgery
Secondary	neoplasm down-staging status	Observation of neoplasm down-staging status in patients according to RECIST 1.1	one month after surgery
Secondary	Investigate operation safety score	Operation safety reference Clavien degree of postoperative complication	one month after surgery
Secondary	local recurrent rate of neoplasm	Observation local recurrent rate of neoplasm in patients	2 years after surgery
Secondary	Quality of life score	Investigate postoperative Quality of life in patients after surgery	one month after surgery
Secondary	Investigate patience pRR (pathologic response rate)	According to the English version of the Japanese Gastric Cancer Classification (JCGC) 3rd edition, pRR is defined as survival of tumor cells remaining in less than 2/3 of the tumor area (level Ib or higher)	7 days after surgery
Secondary	R0 resection	R0 resection indicates a microscopically margin-negative resection,in which no gross or microscopic tumor remains in the primary tumor bed	immediately after surgery
