Résumé
Sunitinib, an antiangiogenic molecule, is one of the first-line standard of care in the treatment of patients with metastatic renal cell carcinoma. However, it only benefits to a subgroup of patients and no predictive markers of sunitinib efficacy have been identified. Twenty-eight metastatic renal cell carcinomas were treated with sunitinib-based therapy and another subgroup of 7 primary renal cell cancer patients were also treated by sunitinib in a neoadjuvant trial. Measurements of CD3+CD4+CD25(hi) Foxp3+ regulatory T cells, an immunosuppressive cell population, were performed before and after each cycle of treatment in blood and tumor in a prospective study. We observed a decrease in the number of peripheral blood Foxp3+ regulatory T cells after each cycle of sunitinib-based therapy. The overall survival was significantly longer in patients showing a decrease in the number of Foxp3+ regulatory T cells after 2 or 3 cycles of treatment (P
