Summary
Brief summary (as posted)
RATIONALE: Vaccines may make the body build an immune response to kill tumor cells. Drugs used in chemotherapy use different ways to stop tumor cells from dividing so they stop growing or die. Combining vaccine therapy with chemotherapy may kill more tumor cells. PURPOSE: Phase II trial to study the effectiveness of combining vaccine therapy and chemotherapy in treating patients who have metastatic or locally recurrent stomach cancer or esophageal cancer.
