研究目的:

主要研究目的:评价一线诱导治疗后西妥昔单抗β联合伊立替康维持治疗RAS/BRAF基因野生型、转移性结直肠癌患者的有效性与安全性。 探索性研究目的:额外收集患者血液样本,通过血清外泌体检测探索性分析外泌体相关分子生物标志物与疗效及预后之间的相关性。  

Objectives of Study:

Primary Objective:To evaluate the efficacy and safety of maintenance therapy with cetuximab β plus irinotecan in patients with RAS/BRAF wild-type metastatic colorectal cancer following first-line induction therapy. Exploratory Objectives:To collect additional blood samples from patients and conduct exploratory analyses of the correlation between exosome-related molecular biomarkers in serum exosomes and treatment efficacy as well as prognosis via serum exosome detection.
