<qa>  What is the primary outcome of the tumor biopsy?On day 1 of each cycle, peripheral blood will be collected to measure peptide-specific IFN-y production. Before treatment and after every 3 cycles, PBMC will be collected to quantify peptide specific CD8 T cells by flow cytometric analysis with peptideHLA-A2 tetramers, and evidence for a molecular response will be assessed by performing RT-PCR. for melanoma antigens on peripheral blood samples. In addition, prior to treatment, after the first 3 cycles, and at the time of going off- study, a tumor biopsy will be performed to assess the immune response in the tumor microenvironment, including gene array analysis. It is hoped that these studies will uncover the reason for lack of clinical response in patients with residual tumors. Clinical response will be assessed as a secondary outcome.
