Complex treatment of patients with localized and locally advanced renal-cell carcinoma, by using preoperative embolization

Background: Treatment of localized and locally advanced renal cancer is still of current importance. Subjects and methods: 100 cases of pT2, pT3a renal cell carcinoma were compared in 2 groups according to the treatment strategy: 1) patients who had received complex treatment (renal artery embolization and surgical treatment) (a study group) and 2) those who had been surgically treated (a control group). The criterion for efficiency was the median duration of relapse- free survival. Results: the median duration of relapse-free survival was 37 months in study group patients with pT2 disease and 39.5 months in the control group. The relapse-free survival varies greatly: 30.5 months in patients with pT3a in the study group and 16.5 months in the control group. Conclusion: The findings have led to the conclusion that it is necessary to make preoperative renal artery embolization in the complex treatment of patients with pT3a renal cell carcinoma
