People with pancreatic cancer that cannot be cured by surgery are being asked to participate in this study.

The purpose of this study is to test the ability of the radiation oncologists to administer Cyberknife therapy along with Gemcitabine chemotherapy for patients with pancreatic cancer. Radiation and Gemcitabine are both effective at killing cancer cells but they generally cannot be given at the same time. Cyberknife therapy is highly focused radiation that is being used extensively at Georgetown University and around the United States to treat a number of cancers. It is believed that because Cyberknife is so highly focused it can be given safely with regular doses of chemotherapy to attack cancer cells in two ways at the same time.

This research is being done because it is not known if using Cyberknife with chemotherapy will be a safe way to treat pancreatic cancer.

Primary Outcome Measures:
  • To demonstrate that radiation treatments can be reproduced as determined by evaluation of the prescription isodose curves [ Time Frame: 10 days ] [ Designated as safety issue: Yes ]

Secondary Outcome Measures:
  • Acute and late toxicity as determined by patient self-reporting instruments that assess gastrointestinal side effects [ Time Frame: 6 months ] [ Designated as safety issue: Yes ]
  • Quality of life as determined by patient self-reporting instruments [ Time Frame: 6 months ] [ Designated as safety issue: No ]
  • Acute stomach/duodenal mucosa injury as assessed by upper endoscopy [ Time Frame: one month ] [ Designated as safety issue: Yes ]
  • Late stomach/duodenal mucosa injury as assessed by upper endoscopy [ Time Frame: 6 months ] [ Designated as safety issue: Yes ]
  • Feasibility of integrating metabolomic analysis into the evaluation of patients with unresectable pancreatic cancer undergoing chemotherapy and radiation therapy measured by the ability to collect tumor specimens [ Time Frame: 6 months ] [ Designated as safety issue: No ]
  • The feasibility of measuring pancreatic cancer stem cell populations by analysis of fine needle aspirate specimens [ Time Frame: 6 months ] [ Designated as safety issue: No ]
