A Phase II Study to Assess the Efficacy and Safety of Preoperative Chemo With Radiation Therapy for Patients With Borderline Unresectable Adenocarcinoma of the Pancreas

The purpose of this phase II clinical trial study is to assess the resection rate among subjects who have been initially diagnosed with unresectable or borderline resectable pancreatic adenocarcinoma. This will be done by providing preoperative treatment that will include alternating cycles of chemotherapy and radiotherapy treatment. In addition, this clinical trial will assess the safety of preoperative chemotherapy with radiation therapy for subjects with unresectable or borderline resectable adenocarcinoma of the pancreatic head, assess margin-negative resection rates, disease-free survival, assess overall survival rates, and determine patterns of local and distant recurrence.
