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.
PURPOSE: This phase I/II trial is studying the side effects of vaccine therapy and to see how well it works in treating patients with stage IV melanoma.
Full description
OBJECTIVES:
OUTLINE: This is an open-label, nonrandomized study. Patients are sequentially assigned to receive dendritic cells (DC) transfected at either immature or mature stage.
Approximately 2-3 weeks before leukapheresis, patients undergo surgical excision or biopsy of the tumor to obtain tumor tissue for RNA isolation. RNA is amplified from the tumor sample by polymerase chain reaction (PCR). Patients then undergo leukapheresis to harvest peripheral blood mononuclear cells for the production of DC on day -14 . DC at immature or mature stage are transfected with autologous PCR-amplified tumor RNA to produce the vaccine. Patients receive vaccine intradermally (ID) on days 1, 15, 29, 43, 57, and between days 71-74 in the absence of disease progression or unacceptable toxicity. Patients undergo evaluation between days 71-74. Patients with responding or stable disease or minor disease progression receive booster vaccine ID on days 99, 127, between days 162-164, on day 205, between days 253-255, 351-354, 442-444, 533-535, 624-626, and 715-718 in the absence of disease progression or unacceptable toxicity. Patients also undergo additional leukapheresis between days 71-74, 351-354, and 715-718. Patients with responding or stable disease may continue to undergo leukapheresis and receive booster vaccine ID every 12-24 weeks off study.
After completion of study treatment, patients are followed periodically for up to 10 years.
PROJECTED ACCRUAL: A total of 8-30 patients will be accrued for this study within 6-12 months.

Inclusion and exclusion criteria
DISEASE CHARACTERISTICS:
Histologically confirmed cutaneous melanoma*
NOTE: *Metastatic melanoma with an unknown primary tumor allowed provided ocular melanoma can be definitely excluded and origin from the skin is likely

Failed ≥ 1 standard chemotherapy or chemoimmunotherapy regimen (e.g., dacarbazine or cisplatin monotherapy)
At least 1 metastatic lesion surgically accessible* for excision or biopsy to obtain tumor material for RNA isolation** NOTE: *Surgically accessible metastatic lesion not required provided properly processed tumor material or isolated tumor RNA is available from a metastasis excised or biopsied within the past 6 months
NOTE: **Major surgery not allowed for the acquisition of metastatic material solely for RNA isolation
No active CNS metastases by CT scan or MRI
