PROGNOSIS OF RENAL CELL CARCINOMA

INFLUENCE OF PREOPERATIVE RENAL ARTERIAL EMBOLIZATION

Abstract

In 45 cases of renal cell carcinoma undergone radical nephrectomy at the Jikei University Hospital during the 5 year period from 1975 to 1979, the effect of renal arterial embolic occlusion on prognosis was assessed by dividing these cases into 2 groups: groups undergone (22 cases) or not undergone (23 cases) renal arterial embolic measure. In cases without metastatic lesion at the time of operation, a tendency was observed that the incidence of postoperative metastasis was lower with more favourable survival for the group undergone the embolic occulsion than that without it. From these findings it was considered that this technique could reduce the risk of spreading of tumor cells at the time of operation.
On the other hand, among cases with metastatic lesion at the time of operation there were more cases which survived for a longer period in the group undergone renal arterial embolic occlusion.
This technique may be useful to improve immunological competence of patients with renal cell carcinoma. For decisive evaluation it is required to observe more patients for a longer period. However, it may be said that this is a valuable therapeutic measure as a preoperative treatment for patients with renal cell carcinoma.
