Abstract
BACKGROUND

Primary vaginal cancer is rare and most vaginal tumors are metastatic, often arising from adjacent gynecologic structures. Primary vaginal cancers are also more common among postmenopausal women and most of these are squamous cell carcinomas, with adenocarcinomas being relatively rare. Vaginal bleeding is the most common clinical manifestation of vaginal adenocarcinoma. About 70% of vaginal adenocarcinomas are stage I lesions at the time of diagnosis, for which radical surgery is recommended. However, more advanced vaginal cancers are not amenable to radical surgical treatment and have poor clinical outcomes. Optimal treatments modes are still being explored. Here, we report a rare case of stage IIb primary vaginal adenocarcinoma for which an individually designed vaginal applicator for after-loading radiotherapy was used to achieve good tumor control.

CASE SUMMARY

A 62-year-old woman presented to our clinic after 3 months of abnormal postmenopausal vaginal bleeding. Gynecological examination, computed tomography (CT), and positron emission tomography-CT showed a large mass (about 5 cm) on the anterior vaginal wall. Colposcopy biopsy confirmed adenocarcinoma of vaginal origin. After three cycles of carboplatin plus paclitaxel chemotherapy, the lesion partially shrunk. The patient then received external irradiation of 45 gray (gy) in 25 fractions, which further reduced the vaginal lesion, followed by after-loading radiotherapy of 30 gy in 5 fractions with an individually designed vaginal applicator. Three months later, magnetic resonance imaging showed a slight thickening of the anterior vaginal wall.

CONCLUSION

Primary vaginal adenocarcinoma is rare, and prognosis is poor in most vaginal cancers of locally advanced stages, which cannot be treated with radical surgery. Better tumor control can be achieved with an individualized vaginal applicator that allows administration of a higher radical dose to the tumor area while protecting normal tissues.
