Abstract

Background \& aims: Sarcopenia has been associated with poor prognosis in a number of malignancies. However, whether sarcopenia is associated with colorectal cancer (CRC) prognosis in a metastatic setting remains unclear. The aim of the study presented was to evaluate the impact of sarcopenia on progression-free survival (PFS) and overall survival (OS) in patients with metastatic CRC. Methods: We retrospectively studied 72 patients with stage IV CRC treated at the University of Campinas between 2009 and 2015. Computed tomography images were analyzed to assess body composition. The Kaplan-Meier and multivariate Cox proportional hazards regression were used for survival analysis and to evaluate the influence of sarcopenia on PFS and OS. Results: Median PFS for sarcopenic patients (n = 32) was 7.2 months, which was significantly different from non-sarcopenic patients (n = 40), which was 15.2 months (hazard ratio {[}HR]: 1.78; 95% confidence interval {[}CI], 1.00-3.14; P = 0.048). Sarcopenia was also a significant predictor of OS. Median OS for sarcopenic patients was 12.5 months versus 36.7 months for non-sarcopenic patients (HR: 1.86; 95% CI, 1.02-3.38; P = 0.043), after adjustment for number of metastatic lesions, metastasectomy, and performance status. Conclusions: Sarcopenia was associated with worse CRC PFS and OS. These findings require prospective trials to validate this association.
