BACKGROUND: Recent evidence suggests that depletion of skeletal muscle mass (sarcopenia) and an increased amount of intra-abdominal fat (central obesity) influence cancer statistics. This study investigated the impact of sarcopenia and central obesity on survival in patients undergoing liver resection for colorectal liver metastases (CLM). METHODS: Diagnostic imaging from patients who had hepatic resection for CLM in one centre between 2001 and 2009, and who had assessable perioperative computed tomograms, was analysed retrospectively. Total cross-sectional areas of skeletal muscle and intra-abdominal fat, and their influence on outcome, were analysed. RESULTS: Of the 196 patients included in the study, 38 (19·4 per cent) were classified as having sarcopenia. Five-year disease-free (15 per cent versus 28·5 per cent in patients without sarcopenia; P = 0·002) and overall (20 per cent versus 49·9 per cent respectively; P < 0·001) survival rates were lower for patients with sarcopenia at a median follow-up of 29 (range 1-97) months. Sarcopenia was an independent predictor of worse recurrence-free (hazard ratio (HR) 1·88, 95 per cent confidence interval 1·25 to 2·82; P = 0·002) and overall (HR 2·53, 1·60 to 4·01; P < 0·001) survival. Central obesity was associated with an increased risk of recurrence in men (P = 0·032), but not in women (P = 0·712). CONCLUSION: Sarcopenia has a negative impact on cancer outcomes following resection of CLM.
