A case of metachronous oligo-hepatic and peritoneal metastases of pancreatic cancer with a favorable outcome after conversion surgery combined with perioperative sequential chemotherapy.

Pancreatic ductal adenocarcinoma (PDAC) is one of the most aggressive malignancies, and the prognosis for its recurrence after surgery is very poor. Here, we report a case of metachronous oligo-hepatic and peritoneal metastases in a patient who survived without recurrence for 3 years after conversion surgery combined with perioperative sequential chemotherapy using gemcitabine plus nab-paclitaxel (GnP) and modified FOLFIRINOX (mFOLFIRINOX). The patient was a 70-year-old man with pancreatic ductal carcinoma, classified as cT3N0M0, cStage IIA, who underwent a distal pancreatosplenectomy.
