[A Case of Pathological Complete Response Following Neoadjuvant Chemotherapy with Gemcitabine plus Nab-Paclitaxel in Borderline Resectable Pancreatic Cancer].

ABSTRACT

We report a resected case with a pathological complete response(pCR)after neoadjuvant chemotherapy for borderline resectable pancreatic cancer(BRPC). A 67-year-old woman who had been treated for type 2 diabetes mellitus in our hospital presented with an exacerbation of diabetes. An abdominal CT scan confirmed a hypovascular mass in the pancreas body consistent with BRPC. After 3 courses of chemotherapy with gemcitabine plus nab-paclitaxel(GnP), her elevated DUPAN-2 level normalized. A follow up CT scan revealed that the tumor had decreased in size, and no distant metastasis was detected. Distal pancreatectomy with en-bloc celiac axis resection was performed. Histopathological examination of the resected specimens showed no evidence of residual cancer cells(pCR). The patient remains disease-free 8 months after surgery. Neoadjuvant GnP chemotherapy may be useful for BRPC.
