Denileukin Diftitox Followed by Vaccine Therapy in Treating Patients With Metastatic Cancer

RATIONALE: Combinations of biological substances in denileukin diftitox may be able to carry cancer-killing substances directly to the cancer cells. Vaccines made from a gene-modified virus and a person’s white blood cells may help the body build an effective immune response to kill cancer cells. Giving denileukin diftitox together with vaccine therapy may kill more cancer cells.
PURPOSE: This phase I trial is studying the side effects of giving denileukin diftitox together with vaccine therapy in treating patients with metastatic cancer that expresses carcinoembryonic antigen.
