Computed tomography (CT) analysis of body composition has garnered interest as a potential prognostic tool in those with cancer. A range of pre-defined thresholds currently exist within the literature to define low skeletal muscle mass and density. The aim of the present systematic review was to assess the prevalence of low skeletal muscle index (SMI) and density (SMD) within the literature, across a range of common solid tumours.

计算机断层扫描定义的癌症患者骨骼肌指数和密度低：来自系统评价的观察

身体成分的计算机断层扫描 (CT) 分析作为癌症患者的潜在预后工具已引起人们的兴趣。目前在文献中存在一系列预定义的阈值来定义低骨骼肌质量和密度。本系统评价的目的是评估文献中低骨骼肌指数 (SMI) 和密度 (SMD) 在一系列常见实体瘤中的患病率。
