Experimental: Radiation therapy plus chemotherapy
MR guided dose escalated radiation therapy plus concurrent chemotherapy in unresectable non-metastatic pancreas cancer. Radiation therapy dose escalation to an MR-defined GTV of up to 69.75 Gy at 2.25 Gy per fraction and concurrent Gemcitabine or Capecitabine.
Radiation: Radiation Therapy
Radiation therapy dose escalation to an MR-defined gross tumor volume (GTV) of up to 69.75 Gy at 2.25 Gy per fraction.
Other Name: Dose escalation radiation therapy
Drug: Concurrent chemotherapy (Gemcitabine, Capecitabine)
Gemcitabine 400mg/m^2 IV weekly x 6 doses. Capecitabine 825 mg/m^2 by mouth twice daily Monday-Friday on days of radiation use 500 mg tablets.
- Efficacy of dose escalation [ Time Frame: Baseline and 1 year ]This measure is the change from baseline of gross tumor volume for participants achieving a complete response (CR) or partial response (PR) or maintaining stable disease (SD) by RECIST 1.1 criteria.
- Radiographic response [ Time Frame: Baseline and 1 year ]Number of participants treated with the proposed dose escalation achieving CR, PR, or SD measured by RECIST 1.1 criteria from magnetic resonance imaging (MRI), positron emission tomography (PET) or computed tomography (SC) scans.
- Serum Cancer Antigen 19-9 (CA19-9) [ Time Frame: Baseline and 1 year ]This measure will be the mean serum activity of CA19-9 in units/mL.
- Serum Carcinoembryonic Antigen (CEA) [ Time Frame: Baseline and 1 year ]This measure will be the mean serum concentration of CEA in ng/mL.
- Radiation induced toxicity [ Time Frame: 3 months post treatment ]This measure will be the number of subjects experiencing a serious adverse event or grade three or higher non-serious adverse event by CTCAE v4.03 criteria that is definitely, likely, or possibly attributable to the radiation therapy.
- SMAD 4 expression [ Time Frame: 4 years ]This measure will be the number of participants whose tumor biopsy is positive for the presence of SMAD 4 protein.
- Overall Survival [ Time Frame: 1 and 2 years ]This measure will be the number of subjects alive at one and two years following the end of radiation treatment.
- Progression Free Survival [ Time Frame: 1 and 2 years ]This measure will be the number of subjects achieving a CR or PR or maintaining SD by RECIST 1.1 criteria one and two years following the end of radiation treatment.
