TRANSITIONAL-CELL CARCINOMA OF THE RENAL PELVIS OR URETER - PATTERNS OF FAILURE

Objectives. To identify recurrence patterns and possible indications for adjuv Methods. Ninety-four patients with transitional cell carcinoma of the renal pelvis or ureter were reviewed to determine their pattern of failure. Factors including gender and age, tumor stage and grade, and extent of surgical procedure and adjuvant radiation therapy (RT) were analyzed with respect to local and distant recurrence and survival. Results. Seventy-seven patients had resections without residual. On multivariate analysis, grade (P = 0.01) and adjuvant RT (P = 0.02) had significant effects on local control. Metastases were solely dependent on stage (P = 0.0001). Survival was dependent on stage (P = 0.0059) and age (P = 0.036), with the use of adjuvant RT of borderline significance (P = 0.07). Twenty-seven patients were excluded from local failure and survival analysis; of these, 3 died within 1 month of surgery, 5 had metastasis at presentation, and 19 had local disease that was unresectable. Eleven of these 19 were treated by RT, resulting in 2 long-term disease-free survivors after receiving doses of 45 and 50.4 Gy. Conclusions. In patients with adverse factors, such as high grade or stage, close margins, or positive nodes, local control can be improved with adjuvant radiation. Improvement in survival is of borderline significance on multivariate analysis, with approximately 50% of high stage or grade patients developing metastasis.
