Study design:

Case-Control study 

研究目的:

明确血清 GDF-15在消化道肿瘤患者与健康人群中的表达差异,验证其作为 消化道肿瘤诊断标志物的效能。 探索血清GDF-15水平动态变化与消化道肿瘤患者早期临床诊断相关性,探讨其临床应用潜力。 通过筛出与GDF-15有关的变量利用多种机器学习算法构建消化系统肿瘤早期诊断模型,通过多种模型评估其与其他有意义变量联合应用的诊断价值。  

Objectives of Study:

Clarify the differences in serum GDF-15 expression between patients with gastrointestinal tumors and healthy populations, and verify its efficacy as a diagnostic marker for gastrointestinal tumors. Explore the correlation between dynamic changes in serum GDF-15 levels and early clinical diagnosis in patients with gastrointestinal tumors, and investigate its potential clinical application. By screening variables related to GDF-15, construct early diagnostic models for gastrointestinal tumors using various machine learning algorithms, and evaluate the diagnostic value of their combined application with other meaningful variables through multiple models.
