title: [A clinical study of patients undergoing curative surgery for renal pelvic and ureteral cancers].
abstract: We retrospectively studied 30 patients who underwent curative surgery for renal pelvic and/or ureteral cancer between August 1987 and August 1998. Their clinicopathological features were classified by the criteria of the Japanese Urological Association. The 1-, 3-, and 5-year cause-specific survival rates were, respectively, 100, 95.5, and 85.1%, while the disease-free rates were 100, 78.9, and 78.9% by the Kaplan-Meier method. Prognostic factors were evaluated by the log-rank test. The significant prognostic factors were pT3 and pV1 for cause-specific survival (p = 0.0277, p = 0.0025), while pT2 (or higher), grade 3, and pV1 were significant for disease-free survival (p = 0.0271, p = 0.0327, and p = 0.0002). Nine patients who received adjuvant chemotherapy are alive, but 3 patients have relapsed. Chemotherapy did not have a significant effect on the cause-specific survival or disease-free survival.
