Abstract
Neoadjuvant chemoradiation therapy (NACRT) is increasingly used in patients with a potentially or borderline resectable pancreatic ductal adenocarcinoma (PDA) and it has been shown to improve survival and reduce locoregional metastatic disease. It is rare for patients with PDA to have a pathological complete response (pCR) to NACRT, but such patients reportedly have a good prognosis. We report the clinicopathological findings of two cases of pCR to NACRT in PDA. Both patients underwent pancreatectomy after NACRT (5-fluorouracil, mitomycin C, cisplatin, and radiation). Neither had residual invasive carcinoma and both showed extensive fibrotic regions with several ducts regarded as having pancreatic intraepithelial neoplasia 3/carcinoma in situ in their post-therapy specimens. It is noteworthy that both patients had a history of a second primary cancer. They both had comparatively good outcomes: one lived for 9 years after the initial pancreatectomy and the other is still alive without recurrence after 2 years.Entities:
