Abstract
Background: Older patients with cancer present intense loss of muscle mass (MM). Calf circumference (CC) is a simple measurement that assesses MM. This study analyzed the accuracy and association between low CC and negative outcomes in older patients with solid tumors.
Methods: A secondary analysis of a prospective cohort study of inpatients with cancer was conducted. Low CC was defined as CC ≤34 cm in males and ≤33 cm in females. The CC was adjusted for body mass index by reducing 3 or 7 cm for BMI (in kg/m2) of 25-29.9 and 30-39.9, respectively. Accuracy tests and regression analyses were performed to evaluate the criterion validity of low CC for predicting length of stay (LOS) and readmission.
Results: A total of 248 inpatients were evaluated (69.7 [standard deviation (SD) 7.2]; 59.7% men). Among them, 31% had a low CC. A low CC (crude and adjusted for BMI) showed poor performance in predicting LOS and readmission. In the adjusted analysis, older patients with low CC had a 2.45-fold increased risk of LOS ≥ 4 days.
Conclusion: Low CC did not perform well in predicting negative outcomes in older patients with solid tumors. However, low CC was positively associated with LOS.
背景:老年癌症患者的肌肉质量(MM)严重下降。小腿围(CC)是评估肌肉质量的一种简单测量方法。本研究分析了低 CC 与老年实体瘤患者不良预后之间的准确性和关联性:方法:对癌症住院患者的前瞻性队列研究进行了二次分析。低 CC 的定义是男性 CC ≤34 厘米,女性 CC ≤33 厘米。CC根据体重指数进行调整,体重指数(以千克/平方米为单位)为25-29.9和30-39.9时,CC分别减少3或7厘米。为了评估低 CC 在预测住院时间(LOS)和再入院方面的标准有效性,进行了准确性测试和回归分析:共评估了 248 名住院患者(69.7 [标准差(SD)7.2];59.7% 为男性)。其中,31%的患者有低 CC。低 CC(粗略和根据体重指数调整后)在预测 LOS 和再入院方面表现不佳。在调整后的分析中,低 CC 老年患者的 LOS ≥ 4 天的风险增加了 2.45 倍:低CC不能很好地预测老年实体瘤患者的不良预后。然而,低CC与LOS呈正相关。
