A Phase II Trial of Escalated Dose Proton Radiotherapy With Elective Nodal Irradiation and Concomitant Chemotherapy for Patients With Unresectable, Borderline Resectable or Medically Inoperable Pancreatic Adenocarcinoma
Proton Collaborative Group
Summary
The prognosis for patients with localized pancreatic adenocarcinoma who are not surgical candidates is poor. Patients characterized as having "borderline resectable" disease treated with preoperative chemo-radiotherapy fair somewhat better - although many of these patients are not converted to resectability. It may be argued that intensification of local and regional therapy might 1.) Increase the share of patients able to undergo curative surgery and 2.) Improve the local disease control interval and extend survival for patients who remain unresectable. Therefore, the purpose of this research study is to determine if an increase in the number of surgical resection pancreatic adenocarcinoma is higher than historical data by using a combined treatment of proton radiation with capecitabine (oral chemotherapy).
Description
Participants as part of this research study will receive Proton radiation over 6 weeks with oral chemotherapy (capecitabine) only taken on radiation days. In addition, If surgery is an option, then surgical resection will be performed at least 8 weeks after treatment with radiation and chemotherapy.

Interventions
- RadiationProton Radiation
Proton Radiation 40.50 Gy relative biological effectiveness (RBE) in 18 fractions to gross disease and elective nodal volume followed by a 22.50 Gy (RBE) in 10 fraction boost to gross disease. Total dose 63 Gy (RBE) in 28 fractions over 6 weeks.
- DrugCapecitabine
Concomitant oral chemotherapy, capecitabine 1000mg by mouth twice daily, 5 days a week (M-F) on radiation days only.
- ProcedureSurgical resection
Surgery between 8 and 16 weeks of radiotherapy completion if radiographic studies suggest operability.
