A total of 50 cases of primary tumors in the renal pelvis and ureter were treated in Tokyo University Branch Hospital (20 cases in 1966-1982) and in Tranomon Hospital (30 cases in 1977-1987). They were composed of 42 men and 8 women (5.3:1) with a mean age of 61 years. 31 patients suffered from renal pelvic tumors, 15 ureteral tumors and 4 tumors in both sites. The tumors were located in the left side in 33 cases, right in 16, and both sides in 1.86% of patients showed gross hematuria. The findings on IVP were filling defect (42%) and nonvisualization (33%). Positive urine cytology was obtained in 12 of 25 cases (48%). Surgery was performed in 47 cases. The remaining 3 cases were with advanced diseases. The surgeries were total nephroureterectomy plus ipsilateral retroperitoneal lymph node dissection in 26 cases, total nephroureterectomy without node dissection in 7, total nephroureterectomy and total cystectomy in 3, nephrectomy in 9, partial nephrectomy in 1 and segmental excision of ureter with ureteroureterostomy in one. Histologically, all tumors were transitional cell carcinoma. Over-all survival rates (Kaplan-Meier's method) of the operated patients at 1, 3, 5 years were 84.2%, 73.1% and 69.4%, respectively. The stage and grade of the tumors affected the prognosis. N factor at lymph node dissection was the most determining factor of prognosis. 3 advanced cases who did not receive surgery for primary site were treated with 5FU in 2, and with CAP in 1.2 of them died of the disease within 1 year after diagnosis, one patient was lost in follow up.(ABSTRACT TRUNCATED AT 250 WORDS)

Thirty-four cases of tumor of the renal pelvis or ureter or both have been treated in our department during the past decade. The primary tumor was in the renal pelvis in 11 cases, in the ureter in 21 cases and in the ureter and renal pelvis in 2 cases, a co-existent tumor in the bladder was found in 4 cases. Seventeen patients had a tumor on the right side and 17 on the left side. The most frequent symptom was gross hematuria (70.6%) and flank pain was the presenting symptom in 7 cases (20.6%). On the intravenous pyelography, a filling defect in the renal pelvis or ureter (41.2%) and nonvisualization (53.0%) were frequent findings. Twenty-nine cases had undergone total nephroureterectomy with resection of a bladder cuff, 3 had simple nephrectomy and 2 had open biopsy alone. Postoperative radiation therapy was done in 1 case, chemotherapy in 10 cases, and 6 cases of them were treated by CAP therapy (cis-dichlorodiamine platinum, doxorubicin and cyclophosphamide). Actual and relative 5-year survival rates were 53.8% and 63.5%, and no significant difference was found in survival rate between the patients with renal pelvic tumors and those with ureteral tumors.

Fifty eight cases of primary tumors in the renal pelvis and ureter were treated at Toranomon Hospital between 1983 and 1992. They consisted of 32 renal pelvic tumors, 21 ureteral tumors and 5 tumors at both sites. The age of the patients ranged from 30 to 84 years (mean 63.1). Surgery was performed in 56 cases. Radical nephroureterectomy with concomitant ipsilateral retroperitoneal lymph node dissection was performed in 38 cases. The other surgeries were radical nephroureterectomy without lymph node dissection in 9, nephrectomy in 4, resection of ureter and reanastomosis in 3, radical nephroureterectomy and cystectomy in 1 and partial nephrectomy in 1. Pathologically, 53 were transitional cell carcinoma (TCC), 2 were TCC plus squamous cell carcinoma and 1 was TCC plus adenocarcinoma. Over-all survival rates (Kaplan-Meier) of 56 surgical cases at 1, 3, 5 years were 92.2, 83.7 and 72.8%, respectively. Combination chemotherapy (M-VAC or CAP) was performed in 9 cases of metastatic disease and 1 case of bilateral disease. Of these 10 cases, one achieved complete remission, 2 no change and 7 had progressive disease. Adjuvant chemotherapy was performed in 21 cases after surgery. These 21 patients were of high risk in recurrence either Grade 3 or pT3. However, the 5-year survival rate was 77.3% in these patients. Thus we conclude that the adjuvant chemotherapy in high risk patients was effective in our cases.
