Summary
Primary ureteral tumors, predominantly transitional cell carcinoma, occurred in 15 patients. Tumor grade and stage significantly impacted survival rates, with low-grade and low-stage tumors showing better prognoses.
Area of Science:
- Urology
- Oncology
Context:
- Retrospective review of 15 primary ureteral tumor cases treated between 1974 and 1983.
- Incidence of primary ureteral tumors was 0.15% among urologic outpatients.
Purpose:
- To analyze the clinical characteristics, treatment, and prognosis of primary ureteral tumors.
Summary:
- Patients aged 50-75 (average 65.5), with a male-to-female ratio of 2.8:1.
- Macrohematuria was the most common symptom (80%); non-functioning kidney on IVP was a frequent finding (73.3%).
- All tumors were transitional cell carcinoma; 26.7% had simultaneous bladder tumors. Survival rates were strongly influenced by tumor grade and stage.
Impact:
- Tumor grade and stage are critical prognostic factors for primary ureteral transitional cell carcinoma.
- Highlights the importance of early detection and accurate staging for improved patient outcomes.
- Provides valuable data for understanding the epidemiology and natural history of these rare tumors.
