研究目的:

本研究拟对pMMR/MSS型结肠癌患者行抗PD-1新辅助免疫治疗+新辅助化疗,化疗方案为mFOLFOX6或FOLFORI,观察新辅助免疫治疗后及术后并发症及近远期疗效,论证结肠癌新辅助免疫治疗的安全性、可行性和有效性;观察奥沙利铂或伊立替康对免疫治疗的不同影响;并通过多色免疫荧光技术,对比观察抗PD-1新辅助免疫治疗患者治疗前手术后TIME(包括肿瘤免疫细胞浸润、TLS等)变化,筛选结肠癌患者中抗PD-1新辅助免疫治疗疗效优势患者的生物标记物,以精准甄别出新辅助免疫治疗获益的特殊类型结肠癌,提高新辅助免疫治疗响应率;基于NGS超深度测序平台建立ctDNA动态检测,探讨抗PD-1新辅助免疫治疗前后及手术后ctDNA动态变化对患者预后的预示作用。从而,为结肠癌患者的治疗提供新的策略,使更多的结肠癌患者从新辅助免疫治疗中获益。  

Objectives of Study:

In this study, patients with pMMR/MSS colon cancer were treated with anti-PD-1 neoadjuvant immunotherapy + neoadjuvant chemotherapy. The chemotherapy regimen was mFOLFOX6 or FOLFORI. The postoperative complications and short-term and long-term effects of neoadjuvant immunotherapy were observed to demonstrate colon cancer. Safety, feasibility and efficacy of neoadjuvant immunotherapy; observe the different effects of oxaliplatin or irinotecan on immunotherapy; and compare and observe the treatment of patients with anti-PD-1 neoadjuvant immunotherapy by multicolor immunofluorescence technology Changes in TIME (including tumor immune cell infiltration, TLS, etc.) before and after surgery, and screen the biomarkers of patients with superior anti-PD-1 neoadjuvant immunotherapy efficacy in colon cancer patients to accurately identify special types of neoadjuvant immunotherapy benefit Colon cancer, improve the response rate of neoadjuvant immunotherapy; establish ctDNA dynamic detection based on NGS ultra-deep sequencing platform, and explore the predictive role of ctDNA dynamic changes before and after anti-PD-1 neoadjuvant immunotherapy and after surgery on patient prognosis. Thus, it provides a new strategy for the treatment of colon cancer patients, so that more colon cancer patients can benefit from neoadjuvant immunotherapy.
