Efficacy of Activated Lymphocytes in Renal Cell Carcinoma.

Phase I and II trials for the treatment of melanoma or renal cell carcinoma have already evaluated lymphokine-activated killer cells and tumor-infiltrating cells. In metastatic renal cell carcinoma, these therapies have shown some complete responses and a low toxicity. In our study, we evaluate the response to a new therapeutic strategy which combines an injection of patient's own activated lymphocytes to a classic immunotherapy with interferon-α and interleukin-2. A secondary objective is to improve cell preparation methods and to characterize functionally and phenotypically injected cells.
