Effect of clinical status on survival in patients with borderline or locally advanced pancreatic adenocarcinoma

Abstract

Objective: To determine the effect of clinical status (weight variation and performance status [PS]) at diagnosis and during induction treatment on resectability and overall survival (OS) rates in patients with borderline resectable (BRPC) or locally advanced pancreatic cancer (LAPC). Methods: From 2005 to 2017, 454 consecutive patients were diagnosed with LAPC or BRPC. We evaluated the PS (0-1 or 2-3), body mass index at diagnosis, and weight loss (WL) > 5% at initial staging and after induction treatment and separated continuous weight loss (CWL) from weight stabilization. Results: A total of 294 patients (64.8%) presented with WL, and 57 patients (12.6%) presented with a PS of 2-3. At restaging, 60 patients (13.2%) presented with CWL. Independent factors that poorly influenced the OS were a PS of 2-3 at diagnosis (P 1 at diagnosis (P 0 at diagnosis (P =.01) and obesity (P
