RATIONALE: Radiofrequency therapy and radiofrequency ablation use a high-frequency electric current to kill tumor cells. Radiofrequency therapy can also cause the body to produce heat-shock proteins which may help kill more tumor cells. Cryotherapy kills tumor cells by freezing them. It is not yet known whether heat-shock proteins caused by radiofrequency therapy given together with radiofrequency ablation or cryotherapy is more effective in treating stage IV melanoma than radiofrequency therapy-induced heat-shock proteins alone.

PURPOSE: This randomized clinical trial is studying the side effects of radiofrequency therapy-induced endogenous heat-shock proteins when given alone or together with radiofrequency ablation or cryotherapy in treating patients with stage IV melanoma.

Additional Information

Official title Endogenous Heat-shock Vaccines for Melanoma A Feasibility Study
Description OBJECTIVES: - Determine the safety and feasibility of endogenous heat-shock protein (hsp)70 synthesis at the site of the tumor using radiofrequency therapy (RFT) in patients with stage IV malignant melanoma. - Determine the safety and feasibility of hsp70 release into the circulation using RFT alone vs RFT followed by radiofrequency ablation (RFA) or cryotherapy in these patients. - Determine the feasibility of inducing a primary antitumor immune response using RFT with or without additional local therapy (i.e., RFA or cryotherapy) in these patients. - Gain preliminary insight into the antitumor efficacy of an in vivo heat shock vaccine in these patients. OUTLINE: Patients are randomized to 1 of 3 arms. - Arm I (closed to enrollment as of 12/7/06): Patients undergo percutaneous biopsy of the target lesion and placement of a localization marker. Patients then undergo radiofrequency therapy (RFT) to the target lesion to induce the production of endogenous heat-shock proteins. After the procedure is completed, patients undergo a second biopsy of the target lesion. Patients also receive an intratumoral injection of sargramostim (GM-CSF) to promote further ablation at the tumor site. - Arm II: Patients undergo percutaneous biopsies and RFT as in arm I followed by radiofrequency ablation of the target lesion. Patients also receive intratumoral GM-CSF as in arm I. - Arm III: Patients undergo percutaneous biopsies and RFT as in arm I followed by cryoablation of the target lesion. Patients also receive intratumoral GM-CSF as in arm I. Tumor tissue samples are obtained by core biopsy immediately before and immediately after RFT for RNA and protein analysis. Tissue samples are assessed by immunohistochemistry for tumor phenotype (i.e., MART-1, tyrosinase, or gp100) and for quantification of infiltrating lymphocytes. Peripheral blood samples are also obtained before and after treatment and periodically during study for immunologic analyses. Peripheral blood-derived lymphocytes are tested with a panel of monoclonal antibodies to estimate the percentages of cytotoxic T lymphocytes (CTLs), including CD4+ and CD8+ T cells as well as B cells, monocytes, and dendritic cells. In addition, assays are performed to estimate T-cell responses to polyclonal stimulus (i.e., PHA), recall antigens (i.e., tetanus toxoid), and HLA alloantigens. Estimates of peptide-specific CTLs are also obtained by enzyme-linked immunosorbent spot assays after in vitro stimulation with peptide-sensitized stimulator cells. Antibodies to extractable nuclear antigens (ENA) and antinuclear antibodies (ANA) will also be evaluated. GM-CSF levels and Hsp70 is assessed in tumor cells and peripheral blood by flow cytometry or enzyme-linked immunosorbent assays. After completion of study therapy, patients are followed periodically for up to 3 years.
