Brief Summary
This study investigates the use of the patients own immune cells to treat prostate cancer. Cells are taken from the patient and grown in the laboratory to become specialized immune cells called dendri...
Detailed Description
Patients undergo one standard apheresis to harvest peripheral mononuclear cells for dendritic cell vaccine preparation. The modified cells (vaccine) are frozen so that multiple injections may be given...
