Summary

RATIONALE: Vaccines made from a person's tumor cells and white blood cells may help the body build an effective immune response to kill tumor cells. Colony-stimulating factors, such as GM-CSF, increase the number of white blood cells and platelets found in bone marrow or peripheral blood. Giving vaccine therapy together with GM-CSF may be an effective treatment for melanoma. PURPOSE: This randomized phase II trial is studying two different vaccine therapy regimens to compare how well they work when given together with GM-CSF in treating patients with recurrent or metastatic melanoma.

Detailed description

OBJECTIVES: * Compare overall survival, progression-free survival, event-free survival, and failure-free survival of patients with metastatic melanoma treated with vaccine therapy comprising irradiated autologous tumor cells vs autologous dendritic cells loaded with irradiated autologous tumor cells in combination with sargramostim (GM-CSF). * Compare the frequency of immune response based on delayed-type hypersensitivity to irradiated autologous tumor cells and serologic and cellular assays at baseline and during and after completion of autologous tumor cell-based vaccine therapy in these patients. * Compare the safety of these regimens in these patients. OUTLINE: This is a randomized study. Patients are stratified according to measurable disease (yes vs no) and location of disease (distant vs regional). Patients are randomized to 1 of 2 treatment arms. * Arm I: Patients receive irradiated autologous tumor cells subcutaneously (SC) and sargramostim (GM-CSF) SC once weekly for 3 weeks and then once monthly for up to 5 months in the absence of disease progression or unacceptable toxicity. * Arm II: Patients receive autologous dendritic cells loaded with irradiated autologous tumor cells SC and GM-CSF SC once weekly for 3 weeks and then once monthly for up to 5 months in the absence of disease progression or unacceptable toxicity. PROJECTED ACCRUAL: A total of 200 patients will be accrued for this study.
