title: Visceral Obesity is Associated with Poor Prognosis in Pancreatic Adenocarcinoma.
abstract: An association between obesity and unfavorable outcomes for various types of malignancy has been established. Nevertheless, the impact of visceral obesity (VO) on outcomes in pancreatic cancer is still unknown and controversial. The aim of this study was to uncover an association between VO and pancreatic cancer outcomes. We retrospectively reviewed 499 patients with pancreatic cancer who were diagnosed and treated in Severance Hospital from January 2006 to December 2011. Compared to the low-VO group (n = 260), the high-VO group (n = 239) was mostly male (68.2% vs. 31.8%, P < 0.001) and was more likely to have current smoking status (29.7% vs. 17.7%, P < 0.001), current alcohol intake status (52.3% vs. 26.4%, P < 0.001) and diabetes mellitus (54.4% vs. 31.9%, P = 0.028). The progression free survival (PFS) and overall survival (OS) were found to be significantly shorter by the Kaplan-Meier method in the high-VO group than in the low-VO group (PFS; P = 0.044, OS: P = 0.013). In addition, the higher percentage of visceral fat was correlated with more lymph node metastasis and shorter OS (P = 0.011 and P = 0.017, respectively). In patients with pancreatic cancer, VO at the time of diagnosis is associated with negative outcomes, such as shorter PFS and OS.
