研究目的:

主要目的: (1)构建并验证一套适用于海岛人群的结直肠癌风险分层模型。模型在内部验证集中对进展期肿瘤的AUC不低于0.75,并明确低、中、高危人群的f-Hb参考阈值; (2)提升目标人群筛查参与率与结肠镜依从率。实施优化策略后,使研究人群的筛查参与率提升至60%以上(参考《健康浙江2030行动纲要》目标),结肠镜依从率较基线(38.41%)提升至少10个百分点,达到50%以上。 次要目的: (1)明确优化策略在固定预算下的成本-效果优势。量化比较优化策略与常规策略的增量成本-效果比,为每额外发现一例进展期肿瘤所需成本提供本地化证据; (2)形成可推广的“FIT梯度+情境适配”筛查操作指南。产出《温岭市海岛地区结直肠癌筛查优化实施方案》一份,以及动员流程手册,为省内类似地区提供范式参考。  

Objectives of Study:

The primary objectives were to: (1) develop and internally validate a colorectal cancer risk-stratification model tailored to island populations, with a target area under the curve (AUC) of ≥0.75 for detecting advanced neoplasia; (2) establish reference thresholds for fecal hemoglobin (f-Hb) to classify individuals into low-, intermediate-, and high-risk groups based on this model. (3) achieve a significant increase in screening uptake and colonoscopy adherence following the implementation of the optimized strategy. Specifically, the target was to attain a screening uptake of >60%—in line with the Healthy Zhejiang 2030 initiative—and to increase colonoscopy adherence by an absolute margin of ≥10 percentage points from a baseline of 38.41% to over 50%. The secondary objectives were to: (1) evaluate the cost-effectiveness of the optimized strategy under a fixed budget by estimating the incremental cost-effectiveness ratio (ICER) per additional advanced neoplasia detected, compared with the standard strategy; (2) develop a generalizable, context-adaptive screening algorithm based on quantitative FIT levels, providing a scalable protocol that can be adapted for implementation in similar island or resource-limited settings.
