N2 - The retrospective analysis includes a group of 50 patients with primary, invasive vaginal cancer treated with brachytherapy in the period of 1982-1993. Over 80% cases were squamous cell carcinoma. There were 14 patients in stage I according to FIGO classification and 20%, 36%, and 16% of patients in stage II, III and IV, respectively. Twenty one patients (42%) received MDR brachytherapy using Cs137 source, the remaining 29 (58%) were treated with HDR using Co60 or Ir192 sources. Among 50 patients 31 (62%) received also external beam irradiation. An overall 5-year actuarial disease-free survival was 40%, and it was 78.6% (11/14), 40% (4/10), 27.8% (5/18), 0% (0/8) for stage I, II, III and IV, respectively. For MDR or HDR5-year disease-free survival was 38% and 41%, respectively. No influence of dose rate on survival has been found (p=0.7). Local failure occurred in 20 patients (40%). Recurrences appeared in 10 patients (20%). Late complications rate was 0% and 17% for MDR and HDR, respectively. Effectiveness of brachytherapy MDR and HDR was similar, whereas serious late complications developed more often after HDR brachytherapy.
