腎細胞癌stage4症例の治療成績

Abstract

At our department, 27 patients with renal cell carcinoma were treated between April 1972 and August 1980. Nine cases had distant metastasis. The highest rate of occurrence of metastasis was to the lungs, in 7 cases, followed by 3 cases of metastasis to the bone, 2 cases each to the liver, brain and adrenal gland, and one case to the skin. Nephrectomy was performed in 7 cases, radiotherapy in 2 cases, renal arterial embolization in 5 cases, hormone therapy in 7 cases, immunotherapy in 6 cases, and chemotherapy in 6 cases. Since the number of cases we treated was not sufficiently large, it is difficult to evaluate the effectiveness of each therapy. Nevertheless, it is noteworthy that 2 patients survived for a relatively long period in spite of metastasis; one patient, in particular, is still well 2 years and 3 months after embolization of the renal artery despite the fact that nephrectomy could not be performed because of renal failure. We think this an interesting case worth mentioning.
