Abstract
BackgroundRecently, several studies have reported that sarcopenia and sarcopenic obesity (SO) could worsen postoperative complications after PD. This study aims to evaluate the effects of preoperative sarcopenia and SO following PD in pancreatic head cancer (PHD). MethodsPreoperative sarcopenia and SO were assessed in 548 patients undergoing PD for PHC at Samsung Medical Centre between 2007 and 2016. The visceral adipose tissue-to-skeletal muscle ratio was calculated from cross-sectional visceral fat and muscle areas on preoperative CT images. The overall survival (OS) and rate of clinically relevant postoperative pancreatic fistula (CR-POPF) among postoperative complications were extracted from prospectively maintained databases. ResultsPreoperative sarcopenia was present in 252 patients (45.9%). The 5-year survival rates of patients with non-sarcopenia and sarcopenia were 28.4% and 23.4% (p = 0.046). Preoperative SO was present in 202 patients (36.9%). After multivariable analysis, the presence of SO was the only independent risk factor for CR-POPF (p = 0.018). ConclusionSarcopenia can be a risk factor affecting decreased OS after PD in patients with PHC. SO is the only predictive factor for CR-POPF after PD in patients with PHC. More observational studies are needed to evaluate the effects of sarcopenia and SO on survival after PD.
