研究目的:

本研究作为真实世界队列研究(Real-World Study, RWS),旨在通过前瞻性队列研究结合回顾性队列数据,基于多维营养指标对胃肠癌患者进行营养表型分层,探讨不同表型间的结局差异,并揭示潜在分子机制,以生成真实世界证据(Real-World Evidence, RWE)支持临床营养管理。具体目标包括: 1. 建立肿瘤营养表型的分类模型:整合基线临床信息(诊疗经过、检验报告)、身体功能评估(握力、步速、坐立实验)、营养指标(如体重指数、营养风险筛查)和生物标志物(如血清白蛋白、C反应蛋白、HDL等脂质代谢指标),对胃肠癌患者进行表型分层。 2. 评估营养表型与临床结局的关联:分析不同营养表型对主要结局指标(如总生存期,OS)以及次要结局(如术后并发症、住院天数、肿瘤复发率)的影响因素,利用回顾性数据验证前瞻性发现。 3. 探索分子基础:针对部分手术患者,收集体液(唾液、尿液、粪便、血液等)和手术标本(肿瘤及周围脂肪组织,体积1cm×1cm×1cm),进行多组学测序,鉴定营养表型相关的基因表达差异及其对患者生存的影响。 4. 提供临床指导:基于研究结果,提出个性化营养管理策略,以优化胃肠癌患者的预后和生活质量。  

Objectives of Study:

1. Establish a classification model for tumor nutritional phenotype: integrate baseline clinical information (diagnosis and treatment history, test reports), physical function assessment (grip strength, walking speed, sitting and standing test), nutritional indicators (such as body mass index, nutritional risk screening), and biomarkers (such as serum albumin, C-reactive protein, HDL and other lipid metabolism indicators) to stratify the phenotype of patients with gastrointestinal cancer.2. Evaluate the association between nutritional phenotypes and clinical outcomes: Analyze the influencing factors of different nutritional phenotypes on primary outcome measures (such as overall survival, OS) and secondary outcomes (such as postoperative complications, length of hospital stay, tumor recurrence rate), and validate prospective findings using retrospective data.3. Explore molecular basis: For some surgical patients, collect body fluids (saliva, urine, feces, blood, etc.) and surgical specimens (tumor and surrounding adipose tissue, volume 1cm × 1cm × 1cm), perform multi omics sequencing, identify nutritional phenotype related gene expression differences and their impact on patient survival.4. Provide clinical guidance: Based on research results, propose personalized nutrition management strategies to optimize the prognosis and quality of life of patients with gastrointestinal cancer.
