Adoptive T cell therapy (ACT) with tumor infiltrating lymphocytes (TIL) has achieved impressive clinical results with durable complete responses in patients with metastatic melanoma. The TILs are isolated from patients own tumor tissue followed by in vitro expansion and activation for around 4-6 weeks. Before TIL infusion the patients receive 1 week of preconditioning chemotherapy with cyclophosphamide and fludarabine. After TIL infusion Interleukin-2 is administered to support T cell activation and proliferation in vivo. Objectives: To evaluate safety and feasibility when treating patients with metastatic renal cell carcinoma with ACT with TILs. To evaluate treatment related immune responses . To evaluate clinical efficacy. Design: Patients will be screened with a physical exam, medical history, blood samples, pulmonary function test, Cr-EDTA clearance, MUGA scan and ECG. Patients will undergo surgery to harvest tumor material for TIL production. Patients is admitted day -8 in order to undergo lymphodepleting chemotherapy with cyclophosphamide and fludara starting day -7. On day 0 patients receive TIL infusion and shortly after starts IL-2 administration with high-dose bolus IL-2 every eight hour for up to 5 days (maximum of 15 doses). The patients will followed until progression or up to 5 years.
