[The role of preoperative embolization in renal cell carcinoma].
In 84 cases of renal cell carcinoma, the effect of embolization was assessed by dividing the patients into two groups: those having undergone (42 cases) or not having undergone (42 cases) embolization. A 16% decrease in tumor volume following embolization using an MMC-micro capsule was noted. In patients without metastasis at nephrectomy, a tendency was observed for the incidence of postoperative metastasis to be lower with more favorable survival for the group with embolization than that without. On the other hand, among cases with metastasis at nephrectomy, there were more patients who survived for a longer period in the embolization group.
