[Results of endovascular interventions (embolization and chemoembolization) in the treatment of operable and extensive kidney cancer].

The results of an all-round examination and complex treatment of 323 patients with renal cell carcinoma were evaluated. Locally advanced tumors were diagnosed in 143 (44.3%) and extended ones--in 180 (66.7%). In patients with locally advanced tumor who had undergone nephrectomy after embolization or chemoembolization, 12-, 24- and 36-month survival rates showed no significant difference. In patients with extended renal carcinoma, 2- and 3-year survival was significantly higher after chemoembolization than after standard embolization of the renal artery.
