SOURCE:
This study, led by Stefano Crippa, MD, PhD, Division of Pancreatic Surgery, Pancreas Translational and Clinical Research Center, San Raffaele Scientific Institute, Vita-Salute San Raffaele University, Milan, Italy, and the accompanying commentary were published online in JAMA Surgery.
LIMITATIONS:
In addition to the limitations noted by the editorialists, others include the study’s retrospective design, which could introduce bias. Because preoperative imaging was not revised, the assigned resectability classes could show variability. Institutional differences existed in the selection process for upfront pancreatectomy. The model cannot be applied to cancer antigen 19.9 nonsecretors and was not externally validated.
DISCLOSURES:
The Italian Association for Cancer Research Special Program in Metastatic Disease and Italian Ministry of Health/Italian Foundation for the Research of Pancreatic Diseases supported the study in the form of a grant. Two authors reported receiving personal fees outside the submitted work. No other disclosures were reported.
