| Summary: | A 60-year-old woman taking anti-platelet drugs was referred to the hospital for the treatment of advanced renal cell carcinoma. CT revealed that the tumor had a diameter of 5 cm and hyper-vascularity. Percutaneous CT-guided cryoablation (CA) was indicated. Since preprocedural arterial embolization failed to provide sufficient embolic effects, sunitinib maleate was administered. It provided good tumor devascularization and volume reduction, which corresponded to downstage. Therefore, the administration contributed to successfully performing subsequent percutaneous CT-guided CA with no serious hemorrhagic complications. Sunitinib maleate may be an alternative to conventional treatments before CA for renal cell carcinoma.
