A CLINICAL STUDY OF 124 CASES OF RENAL CELL CARCINOMA

Abstract

One hundred twenty-four cases of renal cell carinoma treated at Department of Urology, The University of Tokyo were analyzed for their clinical characteristics and prognosis.
To be noted were the recent increase of incidentally detected cases, kidney-sparing technique in curative surgery and adjuvant therapy using biological response modifiers. Prognosis was more favorable in cases with incidental detection, normal ESR or cystic pattern in pathological architecture, whereas that of cases with metastatic lesions or Grade 3 tumors was ominous. Tumor stage as TUMV or Robson stage was useful to predict the prognosis, although one stage contained cases of considerably different survival periods. These results suggested that the efforts to improve prognosis in the present practice should include early detection of renal cancer by promoting health check-up and development of preventive measure of postoperative recurrence. A more proper staging system might also be needed to analyze clinical studies.
