Abstract: | PURPOSE: This report focuses on the prognostic factors of the renal pelvic and ureteral cancer and on the treatment for advanced and/or recurrent cases. METHODS: We reviewed the forty-nine patients with transitional cell carcinoma of the renal pelvis and/or ureter who underwent surgery at the Department of Urology, Osaka National Hospital from April, 1986 to October, 1996. Univariate and multivariate analysis was done on the pathological features from these patients. RESULTS: The patients consisted of 34 males and 15 females and the mean age was 64.9, ranging from 27 to 83. Overall the 1, 3 and 5-year disease specific survival rates were 93.5%, 70.2% and 61.3% respectively by the Kaplan-Meier's method. The prognostic significance of the 6 pathological factors (pT, Grade, INF, pL, pV and pR) were evaluated statistically in terms of generalized Wilcoxon test and/or Cox-Mantel test. All the 6 factors effected on survival rates significantly. However, the grade, INF, pL, pV and pR factors were closely related to the pT factor. Moreover the pT factor was confirmed to be the most important and independent factor according to a multivariate analysis by the Cox's proportional hazard model. And the grade 3 factor with pT2 or higher stage was a high risk factor in recurrences significantly, in spite of curatively operated cases. Thirteen patients with high stage, metastasis or recurrences were treated after operation with the M-VAC or modified M-VAC regimen as preventive, adjuvant and/or salvage chemotherapy. The overall response rate was 72.7% in eleven cases with evaluable lesions, while these regimens could not be expected to improve long-term survival rate. The response rate of combined chemoradiation therapy was 66.7% for six cases with the localized recurrent cancer. CONCLUSIONS: The pT factor was the independent predictor of disease-specific survival. Adjuvant chemotherapy for prevention of cancer recurrence should be considered in the case of pT2 or higher stage plus grade 3 factor, even if curatively operated cases. The M-VAC or modified M-VAC regimen was reconfirmed to be useful as first line chemotherapy of advanced renal pelvic and ureteral cancer. Combined chemoradiation therapy was useful for the localized cancer recurrences, especially as a second line therapy for relapsed cases after M-VAC chemotherapy in this series. |
