目的 基于理论评价工具(theory comparison and selection tool，T-CaST)系统筛选并确定最适用于乳腺癌相关淋巴水肿(breast cancer-related lymphedema，BCRL)自我管理干预方案的理论框架，为干预方案构建提供明确的理论基础。方法 系统检索PubMed、Embase、Web of Science核心数据集等5个英文数据库和中国生物医学文献数据库、中国知网等3个中文数据库中使用理论指导乳腺癌自我管理干预的研究。检索时间为各数据库建库至2025年4月22日。基于T-CaST研究版本，由2位研究者独立对备选理论进行评分与比较，并结合研究实施情境进行综合判断。结果 共纳入14个备选理论。依据T-CaST评分结果及研究具体情境，最终选定健康行为改变整合理论为最适配理论。结论 健康行为改变整合理论具有较高适配性，可为BCRL患者自我管理干预方案的设计提供理论支持。

Objective To systematically screen and determine the most suitable theoretical framework for constructing self-management interventions for breast cancer-related lymphedema (BCRL) based on the theory comparison and selection tool(T-CaST),so as to provide a clear theoretical basis for the construction of intervention programs.Methods Studies on theory-guided self-management interventions for breast cancer were systematically retrieved from 5 English databases (including PubMed,Embase,Web of Science Core Collection)and 3 Chinese databases (including China Biology Medicine Database,China National Knowledge Infrastructure).The retrieval time was from the inception of each database to April 22,2025.Based on the research version of T-CaST,2 researchers independently scored and compared the candidate theories from 4 dimensions,and made a comprehensive judgment taking account of the research implementation context.Results A total of 14 candidate theories were included.According to the T-CaST scores and the specific research context,the integrated theory of health behavior change was finally selected as the most suitable theory.Conclusions The integrated theory of health behavior change shows high fitness and can provide theoretical support for the design of self-management interventions for BCRL patients.
