Intraoperative frozen section analysis of para-aortic lymph nodes after neoadjuvant FOLFIRINOX: will it soon become useless?
Abstract
Positive para-aortic lymph nodes (PALN) (station 16) are commonly detected in the final pathologic examination (ranging from 15 to 26%) among patients who undergo upfront pancreatoduodenectomy for resectable pancreatic ductal adenocarcinoma. However, after neoadjuvant treatment (NAT) the role of positive PALN as a watershed for surgical resection remains unclear. We aimed to determine the incidence of intraoperative detection of PALN after NAT with FOLFIRINOX for pancreatic head adenocarcinoma and its impact on survival, as our policy was to not resect the tumor in such situations.
