title: [Clinical study on renal pelvic and ureteral tumors].
abstract: Thirty five patients with renal pelvic and ureteral tumors were treated at our hospital between 1979 and December 1992. Thirty patients were male and five were female. They ranged in age from 44 to 80 years old (average 67.4 years). The most frequent symptoms were hematuria that was found in 31 cases (24 gross hematuria and 7 microscopic hematuria). Histopathologically, there were 30 transitional cell carcinomas (TCC), 1 squamous cell carcinoma (SCC), 2 TCC > SCC and 1 papillary adenocarcinoma. As to staging, 1 was pTis, 5pTa, 11pT1, 3pT2, 11pT3 and 4pT4. As to grading, 9 were G1, 16 G2 and 9 G3. The incidence of cancerous vessel invasion was noted in 8 of the 29 patients. The 5-year survival rate (Kaplan-Meier's method) was 44.9% for all of the patients. The 5-year survival rate according to staging and according to grading were as follows: 76.7% for low stage (pTis, pTa, pT1, pT2), 24.9% for high stage (pT3, pT4), and 83.3% for G1, 59.9% for G2 and 0% for G3. The 5-year survival rate was 20.8% and 68.7% in the patients with and without vessel invasion, respectively. Grade, stage and cancerous vessel invasion was suggested to be associated with the prognosis in renal pelvic and ureteral tumors.
