This review was undertaken to assess the influence of adjuvant radiation therapy on failure patterns and survival in high stage transitional cell carcinoma of the renal pelvis or ureter. Ninety-four patients with transitional cell carcinoma of the renal pelvis or ureter were retrospectively reviewed. Twenty-six had American Joint Commission stage T3 or T4 N0/+, M0 disease and underwent curative resections (median follow-up 13.5 months, range 3-311). Local failure was defined as recurrence in the tumor bed, regional nodes, or ureteral stump. Time to recurrence and survival were calculated from the time of pathologic diagnosis. Variables associated with local failure, distant metastasis, and survival were analyzed using univariate and multivariate analysis. Seventeen received surgery only, nine received adjuvant radiation therapy (median dose 50 Gy). Local failure occurred in 9 of 17 without and 1 of 9 with adjuvant radiation therapy (p = 0.07). Actuarial 5-year local control was 34% without and 88% with adjuvant radiation therapy. Cox step-wise regression confirmed adjuvant radiation therapy (p = 0.006) and grade (p = 0.006) as significantly associated with local failure. No patients with low grade lesions suffered local failure either with or without adjuvant radiation therapy. High grade lesions had an local failure rate of 15% with and 71% without adjuvant radiation therapy. Metastatic disease occurred in 4 of 9 and 8 of 17 with and without radiation therapy. No significant factors influencing distant failure were identified. Five-year actuarial survival was 44% with and 24% without adjuvant radiation therapy. The survival differences were not statistically significant on univariate or multivariate analysis. High staged transitional cell carcinoma of the renal pelvis or ureter has a substantial local failure risk after surgery alone. Adjuvant radiation therapy markedly reduces this risk but has no impact on distant disease which occurs in approximately 50%. Effective adjuvant therapy will require effective systemic therapy in addition to adjuvant radiation therapy.
