A practical distribution pattern of α-SMA-positive carcinoma associated fibroblasts indicates poor prognosis of patients with pancreatic ductal adenocarcinoma.

Purpose The present study aimed to clarify the distribution pattern of carcinoma associated fibroblasts (CAFs) across pancreatic ductal adenocarcinoma (PDAC) and its prognostic prediction value. Methods Data of two cohorts were retrospectively collected from consecutive patients who underwent primary pancreatic resection from January 2015 to December 2017. We used tumor specimens to screen out the most suitable markers for the spatial distribution analysis for CAFs subpopulations.

Periarterial divestment following neoadjuvant therapy in patients with locally advanced pancreatic cancer with celiac axis invasion: A safe and effective surgical procedure.

Background: Modern pancreatic surgery has gradually changed with the introduction of neoadjuvant therapy. For patients with pancreatic cancer involving peripancreatic visceral arteries who have received neoadjuvant therapy, periarterial divestment has gradually gained popularity, which represents an alternative to arterial resection. There is ongoing debate about whether this approach achieves curative tumor resection comparable to that of arterial resection, and the differences in terms of postoperative complications and oncologic outcomes between the 2 surgical procedures.
