Abstract
Seventy patients admitted to the Tohoku University Hospital during the period from 1959 to 1973 with renal cell carcinoma were studied with regard to clinical and histologic features. Angiography, pyelography and scintigraphy were most contributory to diagnosis. The overall survival rate was 44% at 3 years, 39% at 5 years, and 35% at 10 years. Excluding those patients who exhibited metastasis at the beginning of treatment, the 3-year-survival rate was 78%, 5-year 69%, and 10-year 61%. Concerning clinical symptoms, prognosis was unfavorable for patients with a combination of fever and raised ESR. Although the pathologic staging of tumor growth correlated better with survival rate than the histologic grading of malignancy, both were important determinants in predicting prognosis of individual cases.
