Objective To investigate the clinical effect and adverse effect of high dose rate intracavitary brachytherapy(HDR-ICR) in patients with high grade vaginal intraepithelial neoplasia(HG-VAIN) after hysterectomy. Method A retrospective analysis was performed among 13 patients with HG-VAIN. Out of the 13 patients, one case had VAIN II and twelve cases had VAIN III. All patients underwent HDR-ICR as the only treatment, with a vaginal cylinder and/or oval applicator. All patients followed-up and the recurrence, survival status and short and long-term complications were observed. Result The median overall follow-up time for 13 patients was 55 months(range 12-117 months). One case recurred in 22 months after therapy, and were under control after surgery. The totle effective rate of treatment was 92.3%(12/13). Among 13 patients, three patients had short-term complications, including grade 1-2 rectal reaction in 1 case,grade 1 urinary reaction in 2 cases, which were all mild. Six cases had long-term complications, including grade 2 rectal reaction in 3 cases, grade 3 urinary reaction in 2 cases, grade 3-4 vaginal stricture and ulcer in 1 case. Conclusion HDRICR is an effective treatment regimen for patients with HG-VAIN after hysterectomy, with a high cure rate and acceptable short-and long-term complications.
