Article Title:	Influence of biologic sex and obesity on liver recurrence and survival in patients undergoing upfront surgery for pancreatic adenocarcinoma
Abstract:	<p>Background: The influence of obesity and sex on outcomes in pancreatic adenocarcinoma (PDAC) remains unclear. The association between obesity (body mass index [BMI], >= 30) and biologic sex (male or female) for outcomes in patients with PDAC undergoing a surgery-first approach was investigated. Methods: A prospectively maintained pancreatic cancer database at the Memorial Sloan Kettering Cancer Center was queried to identify all patients undergoing surgery with a pathologic diagnosis of PDAC. Clinicodemographic variables, outcomes, and tumor mutational analyses for all available patients were collected. Cumulative incidence of first recurrence involving the liver was estimated via a cumulative incidence function. Multivariable Cox regression was used to investigate the association between BMI and sex for overall survival. Results: From 2012 to 2022, 939 patients were identified who underwent surgery with a final pathologic diagnosis of PDAC. Median age was 70 years, 52% were male, and 24% were obese (BMI, >= 30). When dichotomized by sex and obesity status (BMI, <30 or >= 30), females with obesity had the lowest cumulative incidence of liver recurrence at 12 and 24 months postsurgery compared to all other groups (13% [95% CI, 7.2%-20%] and 15% [8.7%-23%], respectively). Females with obesity had the longest median overall survival at 37 months. Conclusions: After curative surgery for pancreatic cancer, females with obesity have a significantly lower rate of liver recurrence and the longest median overall survival. This does not appear to be related to surgical quality, receipt of adjuvant therapy, or tumor mutational profile. Investigation into host immune, metabolic, and hormonal parameters is paramount to understanding these differences.</p>
