癌因性厭食之概念分析

癌因性厭食為癌症病人於罹癌及治療期間常見問題之一，會造成病人身心及社會層面許多負面影響，致使生活品質低落。厭食的表現受到腫瘤及治療的影響，且涉及大腦中樞及周圍神經複雜的生理系統，目前鮮少有學者對「癌因性厭食」這個概念進行分析。本文依據Walker and Avant（2018）之概念分析方法，搜尋與統整相關文獻後，歸納癌因性厭食的概念定義、定義性特徵、前置因子與後果、及實證性的評估工具。本文建構典型案例、邊緣案例、相反案例以及相關案例以進一步釐清概念。期冀本文可提升臨床護理人員對癌因性厭食的了解並提供臨床照護實務之參考。

Cancer-related anorexia (CRA) stands as a prevalent concern among cancer patients throughout their illness and treatment journey. Its presence can significantly undermine both the physical and psychosocial well-being of individuals, leading to a diminished quality of life. However, the understanding of CRA remains ambiguous due to the limited body of research addressing this issue. This paper employs Walker and Avant's approach to conduct a thorough concept analysis of CRA. Through a systematic review of literature, the study elucidates the definitions, essential attributes, antecedents, and consequences of CRA, while also delineating its empirical referents. By presenting model, borderline, opposite, and relevant cases, this paper aims to provide clarity on the concept of CRA. It is hoped that this analysis will aid healthcare professionals in gaining a deeper understanding of CRA and serve as a valuable resource for clinical practice.
