In previous preclinical and clinical studies the investigators showed that FNA samples provide a sufficient number of viable tumor cells to perform drug sensitivity assays ex-vivo. The assay protocol is optimized to process tumor FNA samples, where the tumor microenvironment is intact and contains tumor cells and all other tumor-infiltrating inflammatory cells as well as specialized tumor stroma. Prior to initiation of therapy, tumor samples will be collected by FNA from accessible tumor tissue. For the ex vivo assays, aspirates will be obtained from each patient after collection of biopsy samples required for SOC. The FNA samples will be immediately shipped to the Nilogen Laboratory. All proposed assays will be performed at the Nilogen Oncosystems laboratory in Tampa, FL according to CLIA standards.
