In an attempt to investigate the prognosis in malignant tumors of the kidney, follow-up studies in 29 cases of hypernephroma and 11 cases of carcinoma of the renal pelvis were made over a period ranging from 3 to 9 years, and the following results were obtained.
1) The 3-year and 5-year survivals of hypernephroma treated by nephrectomy averaged 39% (9/23) and 30% (4/13), respectively, while the corresponding values for patients with pelvic tumor were 33% (3/9) and 33% (2/6).
2) In either of these malignancies the prognosis was generally poor for those patients a) who visited us late after the first symptoms had appeared, b) in whom the tumor was found to be already large at the first visit, c) in whom the tumor, upon extirpation, was found to be heavy, d) in whom the tumor had already spread outside the renal capsule, or e) in whose condition there were demonstrable metastatic lesions.
