An Open Label Randomized Trial Comparing the Safety and Efficacy of Systemic Chemotherapy (Gemcitabine) to Immunotherapy (CYTOIMPLANT - Intra Tumor Implants of Allogeneic Peripheral Blood Mononuclear Cells Sensitized Against Patient Alloantigens by Mixed Lymphocyte Culture) as First Line Therapy for Patients With Unresectable Locally Advanced, and Metastatic Pancreatic Cancer
RATIONALE: Drugs used in chemotherapy use different ways to stop tumor cells from dividing so they stop growing or die. Biological therapies use different ways to stimulate the immune system and stop cancer cells from growing. It is not yet known whether chemotherapy is more effective than biological therapy in treating patients with cancer of the pancreas. PURPOSE: Randomized phase II trial to compare the effectiveness of gemcitabine with biological therapy in treating patients who have cancer of the pancreas that cannot be surgically removed.
