From 1975 to 1984, 190 patients with renal pelvic tumor and ureteral tumor were treated at our hospitals. With reference to those cases (renal pelvic tumor, 85 cases; ureteral tumor, 83 cases; renal pelvic and ureteral tumor, 22 cases), mainly the effects of adjuvant chemotherapy were analyzed in this study. The survival rate of all the cases was 54.5% at 5 years. To evaluate the effects of adjuvant chemotherapy, the survival rates of two groups (those with or without adjuvant chemotherapy) were compared. For the patients (M(o), (p)T(a)~(p)T4), the survival rates at 5 years were 67.8% for the chemotherapy (+) group and 50.7% for the chemotherapy (-) group. There was no significant difference between the two groups. For the patients (M(o), (p)T(a)~(p)T2), the survival rates were 80.6% and 48.5%, respectively and there was a significant difference (p<0.05). Moreover for the patients (M(o), (p)T(a)~(p)T2, G3) the survival rates were 81.4% and 0%, respectively, and this showed an even more significant difference (p<0.01).
