ABSTRACT
Objective To evaluate treatment results and prognostic factors of 47 patients withprimary urethral transitional cell carcinoma treated with post-operative adjuvant radiotherapy. Methods From October 1998 to October 2008, 47 patients with primary urethral transitional cell carcinoma received postoperative adjuvant radiotherapy. Thirty-one patients had stage T_3/T_4 disease, 7 had lymph node metastasis. Thirty-nine patients had G3 tumor, 13 had stump-positive. The median radiotherapy dose was 60 Gy (36-64 Gy). 81% patients (38/47) were treated with regional irradiation. Results The median follow-up time was 21 months (6 -88 months). The follow-up rate was 92%. The median overall survival time was 35 months (5 -88 months). The 2-and 5-year overall survival rates were 57% and 49%, respectively. In univariate analysis, the median overall survival time was better in patients with stage T_1 or T_2 compared with stage T_3 or T_4 tumor (42 months vs. 19 months,Χ~2 =7. 28,P=0. 007), with age of ≤65 years compared with >65 years (28 mouths vs 18 months,Χ~2 =8.23 ,P =0. 004). There was no significantdifference in the long term survival in patients with non-radical surgery compared with radical mastectomy (21 months vs. 20 months, Χ~2 = 0. 90, P = 0. 344). In multivariate analysis, the stage T_3 or T_4 (Χ~2 = 7. 89, P =0. 005), >65 years old (Χ~2 = 4.85, P = 0. 028), renal pelvis involvement (Χ~2= 5.65, P = 0. 018), and tumor located in the mid or inferior segment (Χ~2=6. 08 ,P =0. 014) were factors associated with poorer prognosis. Conclusions Postoperative adjuvant radiotherapy can improve the efficacy of patients with locally advanced urethral transitional cell carcinoma. Advanced T stage and > 65 years age are associated with poorer prognosis.
