Study design:

Cohort study 

研究目的:

通过监测接受治疗的胃癌患者在治疗前后血浆多基因甲基化水平变化,同时结合影像学和相关肿瘤标志物检测,分析多基因甲基化水平变化与疗效的相关性,最终明确多基因甲基化用于临床胃癌疗效监测的可行性。  

Objectives of Study:

The primary objective is to determine whether pretreatment-to-posttreatment changes in circulating multigene methylation levels correlate with objective response rates (ORR) assessed by contrast-enhanced CT/MRI and levels of serum tumor markers. Secondary endpoints include: (a) time-dependent association between methylation fluctuation patterns and progression-free survival (PFS), (b) comparative diagnostic accuracy of methylation indices versus conventional biomarkers, and (c) feasibility of using methylation thresholds to guide adaptive therapy modification.
