摘要

The authors of the article " Effect of transcatheter renal arterial embolization combined with cryoablation on regulatory CD4+CD25+ T lymphocytes in the peripheral blood of patients with advanced renal carcinoma" have shown the induction of an immune response by combining renal embolization and cryoablation. This letter to the editor further analyses their findings and provides an alternative explanation for their results. ? 2012 Elsevier Inc.
