摘要
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。
Low Calf Circumference is Associated with Prolonged Hospital Stay in Older Patients with Solid Tumors: A Secondary Analysis of a Cohort Study.
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.
