Unresectable pancreatic adenocarcinoma with complete clinical response following chemoradiotherapy.

Locally advanced or metastatic disease is present in 2/3s of patients with pancreatic cancer. Pancreatic cancer patients are assessed as resectable, potentially resectable (borderline) and unresectable according to pre-operative examinations. The chance for operability may be enhanced by using adjuvant-neoadjuvant systemic chemotherapy, radiotherapy or both. The rates of R0 resection may be increased by means of treatment delivered this way. This case report presents a pancreatic adenocarcinoma case that was assessed to be resectable but was identified to be unresectable during surgical exploration, thus received adjuvant chemoradiotherapy. The patient was then re-evaluated, identified as resectable and received pancreaticoduodenectomy.
