    Abstract:
    PURPOSE: To evaluate the role of adjuvant radiation therapy in invasive transitional cell carcinoma of the upper urinary tract, we retrospectively reviewed a series of 26 patients who underwent radical surgery plus postoperative prophylactic irradiation for such a tumor. MATERIALS AND METHODS: Between February 1980 and October 1993, 18 men and 8 women (mean age 65 +/- 9 years, standard deviation) were treated for an invasive transitional cell carcinoma of the upper urinary tract. Tumor location was the renal pelvis in 15 patients (58%). The tumor was pathological stage B in 11 patients (42%) and stage C in 15 (58%). Tumor grade was 2 in 10 patients, 3 in 15 and unknown in 1. One patient had epidermoid metaplasia of urothelial cancer and 9 had node involvement. All patients underwent surgery followed by radiation therapy to a total dose of 45 Gy. to the tumor bed (23) and/or regional nodes (18). RESULTS: After a mean followup of 45 months 13 patients (50%) were alive and 11 were disease-free at analysis. Local tumor relapse, nodal recurrence and metastasis were noted in 1, 4 (15%) and 14 (54%) patients, respectively. All patients with nodal recurrence had metastasis. A secondary location was noted frequently (6 bladder, 1 contralateral renal pelvis and 1 urethral tumors). Overall 5-year survival rate and 5-year survival rate with no evidence of disease were 49% and 30%, respectively. Overall 5-year survival rates were 60% for stage B and 19% for stage C disease (p = 0.07), 49% for node-negative versus 15% for node-positive cancer (p = 0.04), and 90% for grade 2 and 0% for grade 3 tumors (p < 0.01). CONCLUSIONS: In our trial using a radio-surgical approach, local control of disease and survival rates were similar to those reported previously in surgical series. Prophylactic postoperative radiation therapy is not recommended except in prospective randomized studies.
