Effect Analysis of Neoadjuvant Chemoradiotherapy Combined With Surgery in Laparoscope for Advanced Colon Cancer
- Conditions
- Colon Neoplasm
- Interventions
- Radiation: Short-term neoadjuvant chemoradiotherapy
- Registration Number
- NCT05279612
- Lead Sponsor
- Tang-Du Hospital
- Brief 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.
- Detailed 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.

- Primary Outcome Measures
Name Time Method Investigate patients ORR 7 days after surgery Investigate patients ORR(objective response rate ) include CR(complete response) and PR(partial response)
- Secondary Outcome Measures
Name Time Method neoplasm down-staging status one month after surgery Observation of neoplasm down-staging status in patients according to RECIST 1.1
R0 resection immediately after surgery R0 resection indicates a microscopically margin-negative resection,in which no gross or microscopic tumor remains in the primary tumor bed
Quality of life score one month after surgery Investigate postoperative Quality of life in patients after surgery
Investigate operation safety score one month after surgery Operation safety reference Clavien degree of postoperative complication
local recurrent rate of neoplasm 2 years after surgery Observation local recurrent rate of neoplasm in patients
Investigate patience pRR (pathologic response rate) 7 days after surgery 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)
