Body composition assessment and sarcopenia in patients with pancreatic cancer: a systematic review and meta-analysis

Numerous studies have suggested an association between sarcopenia in pancreatic cancer and adverse outcomes. This systematic review examines the evidence for the impact of sarcopenia on post-operative complications and survival A systematic literature search was conducted to identify randomised and non-randomised studies of sarcopenia in pancreatic cancer. Meta-analyses of intra- and post-operative outcomes were performed (operating time, all complications, major complications, pancreatic fistulae, peri-operative mortality, overall survival). Forty-two studies reported the assessment of body composition in 7619 patients. Methods used to assess body composition in patients with pancreatic cancers were computerized tomography (n = 34), bioelectrical impedance analysis (n = 7), and dual-energy-X-ray-absorptiometry (n = 1). Only 10 studies reported the impact of pre-operative sarcopenia upon post-operative outcomes. Sarcopenia was associated with increased peri-operative mortality (OR: 2.40, CI95%:1.19–4.85, p
