Impact of radiofrequency ablation on PBMC subpopulation in patients with renal cell carcinoma.

Purpose: With the development of diagnostic techniques, renal cell carcinoma (RCC) is currently diagnosed in earlier stages, allowing the introduction of less invasive techniques in its management. One of the most promising new treatment methods is based on the utilization of high temperature created by radiofrequency current circulating around the needle probe introduced into the tumor. Besides the direct destruction of the cancer tissue, the treatment may induce immunologic reaction to tumor antigens released from destroyed tumor cell.
