Abstract
Key summary Summarize the established knowledge on this subject * Body composition parameters appear to play a prognostic role in patients with pancreatic carcinoma, but data among studies are inconsistent, [...]
: Background: Parameters to adapt individual treatment strategies for patients with pancreatic ductal adenocarcinoma (PDAC) are urgently needed. The present study aimed to evaluate body composition parameters as predictors of overall survival (OS) in PDAC patients. Methods: Measurements of body composition parameters were performed on computed tomography scans at diagnosis. Height‐standardized and Body Mass Index‐ and sex‐adjusted regression formulas deriving cut‐offs from a healthy population were used. The Kaplan‐Meier method with the log‐rank test was performed for survival analysis. Independent prognostic factors were identified with uni‐ and multivariable Cox regression analyses. Results: In total, 354 patients were analyzed. In a multivariable Cox model, besides tumor stage and resection status, only myosteatosis (HR 1.53; 95% CI 1.10–2.14, p = 0.01) was an independent prognostic factor of OS among body composition parameters. Subgroup analyses revealed that the prognostic impact of myosteatosis was higher in patients ≤68 years of age, with advanced tumor stages and patients without curative intended resection. Conclusions: The analysis of one of the largest Caucasian cohorts to date, demonstrated myosteatosis to be an independent prognostic factor of OS in PDAC. To improve outcomes, prospective trials aiming to investigate the utility of an early assessment of myosteatosis with subsequent intervention by dieticians, sports medicine physicians, and physiotherapists are warranted.
