摘要目的:采用概念分析方法，通过文献对家庭回避癌症沟通的定义、发展、概念应用、特征属性、延伸扩展以及其相近概念等进行系统辨析，厘清家庭回避癌症沟通的概念内涵。方法:检索万方数据库、维普网、中国知网、中国生物医学文献数据库、CINAHL、Embase、PubMed、PsycINFO等数据库中家庭回避癌症沟通的相关文献，检索时限为建库至2023年12月31日。运用Walker和Avant的概念分析法进行分析。结果:通过对相关文献的整理分析，总结出家庭回避癌症沟通的概念特征，包括双向影响（癌症患者和家属均倾向于掩藏自我情绪，彼此互相影响）；信息隐藏（双方缺少沟通行为）；渴望保护（目的是希望保护彼此）。结论:本研究梳理了家庭回避癌症沟通的概念属性，以期为学科领域内相关概念的正确理解提供依据，为家庭回避癌症沟通实践和研究提供概念支持。
