摘要

身体组成，包括由骨骼肌指数（SMI）定义的低骨骼肌质量（LSMM）以及皮下和内脏脂肪组织（SAT和VAT），可以使用横断面成像技术进行评估。先前的研究显示了对包括食管癌（EC）在内的几种肿瘤实体的有希望的预后价值。本研究的目的是分析食管癌患者接受根治性治疗时身体成分参数的可能关联。方法回顾性分析2016年至2023年期间所有接受根治治疗的EC患者。共纳入145例患者，其中女性17例，占11.7%，平均年龄65.9±10.2岁。对于所有患者，分期计算机断层扫描（CT）用于计算LSMM， VAT和SAT。主要研究终点是全因总生存期。统计分析采用Mann-Whitney检验计算组间差异。采用Kaplan-Meier曲线和多变量Cox回归分析检验体成分参数对死亡率的影响。结果观察期内共有51例（35.2%）患者死亡。根据SMI的肌少症阈值，99例（68.2%）归为肌少症，根据VAT阈值，102例（70.3%）归为内脏型肥胖。单变量分析中，肌肉减少症和内脏肥胖与死亡率相关，风险比（HR）分别为2.05（95%可信区间（CI） 1.17, 3.57, p = 0.01）和2.47 （95%CI 1.39, 4.37, p = 0.002）。在多变量分析中，只有两者结合，肌肉减少性肥胖才有显著相关性（HR 2.47, 95% CI 1.39; 4.37, p = 0.002）。结论ct定义的肌肉减少症和内脏性肥胖的结合在行根治性切除的EC中显示出很强的预后相关性。单独考虑肌肉减少症和内脏性肥胖的影响，其预后意义较小。在临床实践中，ct定义的身体成分可能有助于更好地对预后较差的EC患者进行分层。

Prognostic relevance of CT-defined body composition in esophageal cancer patients undergoing curative treatment

Introduction

Body composition including low skeletal muscle mass (LSMM) defined by skeletal muscle index (SMI) and subcutaneous and visceral adipose tissue (SAT and VAT) can be assessed using cross-sectional imaging techniques. Previous studies have shown promising prognostic value for several tumour entities, including esophageal cancer (EC). The aim of this study was to analyse possible associations of body composition parameters in patients with esophageal cancer undergoing curative treatment.

Methods

All patients with EC undergoing curative treatment were retrospectively evaluated between 2016 and 2023. A total of 145 patients (17 female, 11.7 %) with a mean age of 65.9 ± 10.2 years were included in the present analysis. For all patients, staging computed tomography (CT) was used to calculate LSMM, VAT, and SAT. The primary study end point was all-cause overall survival. For statistical analysis group differences were calculated using the Mann-Whitney test. Kaplan-Meier curves and multivariable Cox regression analysis was used to test the effect of body composition parameters on mortality.

Results

In total, 51 patients (35.2 %) of the patient cohort died within the observation period. According to the sarcopenia threshold of the SMI, 99 patients (68.2 %) were classified as sarcopenic and according to the VAT threshold, 102 patients (70.3 %) were classified as visceral obese. Sarcopenia and visceral obesity were associated with mortality with a hazard ratio (HR) of 2.05 (95%confidence interval (CI) 1.17, 3.57, p = 0.01) and 2.47 (95%CI 1.39, 4.37, p = 0.002) in univariable analysis, respectively. Only the combination of both, sarcopenic obesity was significantly associated in multivariable analysis (HR 2.47, 95 %CI 1.39; 4.37, p = 0.002)

Conclusions

The combination of CT-defined sarcopenia and visceral obesity showed a strong prognostic relevance in EC undergoing curative resection. The effect of sarcopenia and visceral obesity considered separately was of lesser prognostic significance. CT-defined body composition may help to better stratify patients with EC at risk of worse outcome in clinical practice.
