Radiotherapy alone for invasive vaginal cancer: outcome with intracavitary high dose rate brachytherapy versus
1Department of Gynecology, University of Vienna, Vienna, Austria.
Purpose:
Our aim was to compare the role of remote afterloaded high-dose-rate brachytherapy (HDRB) with traditional low-dose-rate brachytherapy (LDRB) for patients with invasive primary vaginal carcinoma.
Methods:
The study group comprised 190 patients with invasive carcinoma of the vagina. The patients were staged according to the International Federation of Gynecology and Obstetrics (FIGO) staging system. Eighty patients were treated with intracavitary high-dose rate iridium 192 brachytherapy with or without external beam therapy. These patients are compared with a historical group of 110 patients treated with intracavitary low-dose-rate radium 226 or cesium 137 brachytherapy with or without external beam therapy.
Results:
No significant differences were found for stages, tumor grade or location between the two groups. Crude 5-year survival for all patients was 41% in the former LDRB group, 81% in stage I and 43% in stage II. Overall actuarial 3-year survival and disease-specific survival rates for all patients in the HDRB series were 51% and 66%, respectively. Disease-specific 3-year survival attained 83% in stage I and 66% in stage II. There were no significant differences in local and distant recurrences between the treatment modalities. The comparison of treatments with or without external beam radiation and of complications showed no significant differences between the HDRB and LDRB series.
Conclusion:
With HDRB and its advantages of decreased radiation exposure and patient immobilization and precise positioning, treatment results to be obtained are at least similar to traditional LDRB for primary vaginal cancer.
