Objective To evaluate the efficacy of radiation therapy on primary vaginal cancer with high dose rate brachytherapy alone or in combination with external radiation Methods Fifty one cases with primary vaginal cancer who were treated with high dose rate brachytherapy alone or in combination with the external radiation in Cancer Hospital, Chinese Academy of Medical Sciences from 1989 to 1999 were retrospectively studied,including stage Ⅰ 10 cases,stage Ⅱ 13 cases,stage Ⅲ 23 cases and stage Ⅳ 5 cases WD HDR18 after loading equipment was used in the brachytherapy and 6 or 8 MV linear accelerator was used in the external radiation Results The overall 5 year survival rate with WD HDR18 was 58 8%, with 80 0% for stage Ⅰ,76 9% for stage Ⅱ,65 2% for stage Ⅲ,and 0 0% for stage Ⅳ The comparison of treatments with WD HDR18 and radium therapy showed the 5 year survival rates of the cases of each stage treated with WD HDR18 were higher Conclusion Treatment results obtained with high dose rate brachytherapy are at least similar to traditional radium therapy for primary vaginal cancer
