[Clinical studies on renal pelvic and ureteral tumors].
Clinical studies were performed on 35 patients with renal pelvic and/or ureteral cancer treated at Kitano Hospital between 1988 and 1997. They consisted of 17 renal pelvic cancers, 17 ureteral cancers and 1 renal pelvic and ureteral cancer. Twenty-nine patients were males and six were females, and their age ranged from 41 to 82 years old (average: 62.2). Histologically, 34 were transitional cell carcinoma and 1 was adenocarcinoma. Pathological stage of the tumor was pTa in 34.3%, pT1 in 14.3%, pT2 in 11.4%, pT3 in 37.1%, and pT4 in 2.9%, and grade of the tumor G1 in 11.8%, G2 in 58.8% and G3 in 29.4%. Eighteen patients (51%) had or developed bladder cancer, which preceded the diagnosis of cancer of upper urinary tract in 2 cases, coexisted in 4 cases and developed subsequently in 12 cases. The overall cause-specific survival rate was 91.3% at 1 year, 83.8% at 3 years and 79.4% at 5 years. Tumor stage, grade, lymph node metastasis and vascular invasion had impact on survival.
