Study Details

Brief 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).

Exclusion Criteria:

  • Evidence of distant metastasis.
  • Prior surgical resection.
  • Previous history of invasive malignancy (except non-melanoma skin cancer and low to intermediate risk prostate cancer) unless the participant has been disease free for 5 years prior to registration.

Interventions and Outcome Measures

Arms

experimental: Proton Radiation with capecitabine

The following will be performed in this group: Proton Radiation Therapy with concomitant oral chemotherapy, capecitabine taken on radiation treatment days for 6 weeks. A surgical resection will be performed between 8 and 16 weeks if radiographic studies suggest operability.

Interventions

Proton 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.

Capecitabine

Concomitant oral chemotherapy, capecitabine 1000mg by mouth twice daily, 5 days a week (M-F) on radiation days only.

Surgical resection

Surgery between 8 and 16 weeks of radiotherapy completion if radiographic studies suggest operability.

Primary outcome measure

  • Overall survival at 12 months after radiation therapy [ Time Frame: Approximately 12 months after radiation therapy. ]
