Abstract
Objectives
The aim of this study was to evaluate the combined prognostic value of calf circumference (CC) and serum albumin on mortality in patients with cancer cachexia aged ≥65 years.
Methods
This multicenter cohort study involved 5322 older patients in hospital with cancer cachexia. The combined indicator of CC and albumin was defined as the calf circumference-albumin (CCA) index. Harrell's C index, a time-dependent receiver operating characteristic curve analysis, was used to assess the prognostic performance of the CCA index and other indices. The optimal thresholds method was used to determine the cutoff values of CC and albumin, and the association between the CCA index and all-cause mortality was assessed using Kaplan-Meier analysis and Cox proportional hazard regression models.
Results
A total of 3875 men and 1447 women with a mean age of 72.0 years (range: 68.0–78.0 years) and a mean follow-up time of 55.0 months (range: 25.0–85.0 months) were included in the study. A total of 1269 patients were classified into the low CCA index group (0 score) by the optimal thresholds method. In the overall population, the CCA index showed better differentiating power at predicting mortality in older patients with cancer cachexia compared with CC or albumin alone (C index = 0.639; 95% CI: 0.612–0.666; P < 0.05). The time-dependent receiver operating characteristic curve showed that the CCA index had the highest prognostic value of all the measures studied (P < 0.05). In the overall population, male and female patients with a high CCA index (2 score) showed better performance than those with a low CCA index (0 or 1 score).
Conclusions
The CCA index could significantly predict the mortality of older patients with cancer cachexia, which might provide renewed assistance for future clinical management.
期刊介绍:
Nutrition has an open access mirror journal Nutrition: X, sharing the same aims and scope, editorial team, submission system and rigorous peer review.
Founded by Michael M. Meguid in the early 1980''s, Nutrition presents advances in nutrition research and science, informs its readers on new and advancing technologies and data in clinical nutrition practice, encourages the application of outcomes research and meta-analyses to problems in patient-related nutrition; and seeks to help clarify and set the research, policy and practice agenda for nutrition science to enhance human well-being in the years ahead.
