Summary
Brief summary (as posted)
Primary Objective: To estimate the rate at which radiotherapy to the primary or a metastatic lesion produces an immune response in patients with metastatic carcinoma of the pancreas. Secondary Objectives: To characterize the kinetics of an immune response induced by radiotherapy. To characterize the dependency of the immune response on prior exposure to chemotherapy.

- description
- In this trial, we will deliver low-dose (8Gy in a single fraction) radiotherapy (SBRT or any other acceptable delivery method as determined by the treating physician) for palliation of symptoms in patients in whom it is clinically indicated. This dose is far lower than what has been used in the definitive settings described above. This is a safe dose, and is entirely consistent with the dose range used for routine palliation. Therefore, this trial does not involve an experimental intervention; the research aspect of this protocol is the evaluation of the immune response to clinically indicated palliative radiotherapy.
