Effect Analysis of Neoadjuvant Chemoradiotherapy Combined With Surgery in Laparoscope for Advanced Colon Cancer

Effect Analysis of Neoadjuvant Chemoradiotherapy Combined With Radical Surgery ( CME + D3 ) for Advanced Colon Cancer : Prospective, a Single-arm, Single Central, Clinical Trial Research

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.

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.

Exclusion Criteria:

• Appeared other system cancer
• Patient with postoperative recurrent of colon cancer
• Patient with malignancies history in recent 5 years
• Pregnant or female of suckle period
• The patient have adjuvant radiotherapy record in other system cancer before this time treatment，and Patient with surgical contraindications.
• The patient have accepted adjuvant chemoradiotherapy before this time treatment.
• Distant metastasis found during surgery
