ADDUCTOR POLLICIS MUSCLE THICKNESS AND PREDICTION OF POSTOPERATIVE MORTALITY IN PATIENTS WITH STOMACH CANCER

ABSTRACT Background: Malnutrition is very prevalent in patients with gastric cancer and increases the risk of morbidity and mortality. Adductor pollicis muscle thickness (APMT) appears as an important objective, quick, inexpensive and noninvasive measure to assess the muscle compartment Aim: To compare APMT and other nutritional assessment methods and to correlate these methods with postoperative mortality Methods: Forty-four patients, 29 men and 15 women, mean age of 63±10.2 and ranging from 34-83 years, who underwent nine (20.5%) partial and 34 (77.3%) total gastrectomies due to stomach cancer (stage II to IIIa) were preoperatively assessed by Patient Generated Subjective Global Assessment (PG-SGA), anthropometry and laboratorial profile Results: APMT better predicted death (p摘要 研究背景：营养不良在胃癌患者中极为普遍，会提升患者的发病与死亡风险。拇收肌厚度（Adductor pollicis muscle thickness, APMT）是一种重要的客观、快捷、低成本且无创的肌肉量评估方式。 研究目的：对比拇收肌厚度与其他营养评估方法，并探究上述评估方法与术后死亡率的相关性。 研究方法：本研究纳入44例胃癌患者，其中男性29例、女性15例，平均年龄为63±10.2岁，年龄跨度为34~83岁；所有患者均因II~IIIa期胃癌接受胃切除术，其中9例（20.5%）行部分胃切除术，34例（77.3%）行全胃切除术。术前通过患者自评主观全面营养评估（Patient Generated Subjective Global Assessment, PG-SGA）、人体测量学指标及实验室检测指标对患者进行营养状况评估。 研究结果：拇收肌厚度对患者死亡风险的预测效果更佳（p
