Longitudinal study nonrandomized, multicenter observational descriptive monitoring patients treated with anti-angiogenic for metastatic kidney cancer
One third of patients with kidney cancer are diagnosed in the metastatic stage, and among patients with a localized form, about 30 to 40% will develop metastases after surgery. Medical treatment of metastatic renal cancer include immunotherapy with interferon α and/or IL-2, or targeted therapies such as anti-angiogenic (anti-vascular endothelial growth factor (VEGF), anti-tyrosine kinase inhibitors and m-TOR). These treatments sometimes associated (or IL2 + INF or INF AntiVEGF) do allow for objective response in 15 to 30% of cases (net benefit of targeted therapies), but are carriers of potentially significant side effects and are very expensive. The treatment response is considered on imaging exams repetitive, costly and inconsistently reliable. A serum marker of tumor development would be particularly welcome. CA9 is an oncogene also know as CA IX, carbonic anhydrase 9 or MN/CA9. The gene encoding an oncoprotein called indifferently membrane antigen MN, MN/CA9 isoenzyme, carbonic anhydrase IX CA9, G250/MN/CA9 or protein G250. It was demonstrated that the level of expression of CA9 in tumor tissue can be used as a predictive marker of response to immunotherapy. In previous studies, the investigators tried to use CA9 to improve the differential diagnosis of kidney tumors using tumor biopsy or fine needle aspiration. More recently, the investigators have developed the ELISA and quantitative reat time polymerase chain reaction (RT-PCR) to study the CA9 protein and CA9 mRNA in the serum of patients with non-metastatic kidney cancer. The investigators have thus shown that CA9 was overexpressed prior to surgery and that this expression disappeared after tumor ablation.
Background: - Natural killer (NK) cells are large lymphocytes (a type of white blood cell) that are important in the immune response to cancer. - IL-2 (Aldesleukin) is a substance the body makes that controls the growth and function of many types of cells. The Food and Drug Administration has approved IL-3 for treating metastatic melanoma and kidney cancer. (Metastatic disease is cancer that has spread beyond the primary site.) Objectives: To determine the safety and effectiveness of treating metastatic melanoma and kidney cancer with laboratory-treated NK cells and IL-2. Eligibility: Patients 18 years of age or older with metastatic melanoma or kidney cancer who have previously been treated with high-dose IL-2. Design: - Leukapheresis. Patients under leukapheresis to obtain NK cells for the treatment regimen. Blood is collected through a needle in an arm vein and directed through a cell separator machine where white blood cells are extracted. The rest of the blood is returned to the patient through a needle in the other arm. NK cells are removed from the white blood cells and treated for re-infusion into the patient. - Chemotherapy. Starting 8 days before infusion of the treated NK cells, patients receive intravenous (IV, through a vein) infusions of cyclophosphamide and fludarabine to suppress the immune system. - NK cell infusion. Patients receive a 30-minute IV infusion of NK cells 2 days after the last dose of chemotherapy. - IL-2 therapy. Within 24 hours of the NK cell infusion, patients receive high-dose IL-2 as a 15-minute IV infusion every 8 hours for up to 5 days. A second cycle of IL-2 is given about 14 days after the first. - Blood tests and biopsy. Patients have frequent blood tests during the treatment period and may be asked to undergo a biopsy (surgical removal of a small piece of tumor or lymph node) at the end of treatment to look at the effects of the treatment on the tumor immune cells. - Follow-up evaluation. Patients are evaluated 4-6 weeks after completing treatment. They have a physical examination, scans of tumor sites, blood tests and blood sampling (or leukapheresis) to examine the response to treatment. Patients who improve with treatment return for evaluations every month. Those whose tumor grows again after originally shrinking may receive one additional treatment course.
