A comparison of the roles of surgery and radiation therapy in the management of carcinoma of the female urethra.
Between 1939 and 1986, 42 patients with carcinoma of the female urethra were treated with surgery and/or radiation therapy at the University of Iowa. Ten patients were treated with surgery alone, 28 with radiation therapy alone, and 4 with combined surgery and radiation therapy. Seventeen patients (40%) developed persistent or recurrent disease at the primary site and 15 (36%) had failures in the inguinal nodes. The actuarial 5-year survival rate was 33.5%. Only 36% (10/28) of patients treated with radiation therapy had local failures, compared to 60% (6/10) of those treated with surgery alone. The best results were achieved with combined interstitial and external beam irradiation. Whereas 57% (8/14) of patients who were treated with combined interstitial and external beam irradiation were alive NED at 3 years, none of 7 patients (0%) treated with interstitial implants only and 2 of 7 patients (29%) treated with external beam irradiation alone were alive NED at 3 years. There was a significantly lower inguinal failure rate in patients who received treatment to the inguinal nodes (10%) than in those who did not receive inguinal area treatment (52%), and this translated into a superior 5-year survival for those patients (60% vs 18%). Survival rates did not correlate with histopathologic type in this series, although there were differences in the patterns of failure. Survival rates did correlate well with clinical stage.
