腎・尿管腫瘍の治療成績

Abstract

A survival study was made on 45 renal cell carcinomas and 28 tumors of the renal pelvic and ureter experienced at the Sapporo City General Hospital during the ten years period, 1969-1978. 1) Relative 5 year survival rate was 43% in renal cell carcinoma and 30% in renal pelvic and ureteral tumor. 2) Survival rate of renal cell carcinoma closely related with its stage. All the cases with advanced extension, tumor emboli in the renal vein or inferior vena cava or distant metastasis were dead within 4 years. All but two of these cases showed striking acceleration of ESR and strongly positive CRP. 3) Relative 5 year survival rate of renal pelvic and ureteral tumor differed by grade. In low grade tumors, it was 100%, while in high grade only 10% which mostly belonged to the high stage group. Postoperative recurrence in the bladder was seen in 6 occasions in 3 patients. One case of early diagnosis was presented in which cytological study of the ureteral urine through catheter lead to diagnosis of carcinoma in situ of the renal pelvis.
