Objective: Six cases of endodermal sinus tumor (EST) of the vagina were reported focusing on the results of conservative treatment and outcome of long-term follow up. Methods: We reviewed a cohort of six cases with EST of the vagina diagnosed and treated in our hospital. CT scan, detection of serum AFP level, examination under anesthesia and biopsy were performed before and after treatment to evaluate the tumor status. The diagnoses were confirmed by pathological and imaging findings. All patients were treated with bleomycin, etoposide and cisplatin (BEP) combination chemotherapy alone. Complete remission (CR) includes the normal level of serum AFP, no tumor detected by CT scan and the negative result of pathology. Long-term follow up was carried out according to our regulation. Results: The mean onset age was 18.2 months. The average tumor size was 4.5 cm. Serum AFP level was markedly elevated before treatment and decreased dramatically after chemotherapy and drop to the normal level after two to three courses of chemotherapy (average 2.5 courses). The patients received averagely six courses of chemotherapy and all the six patients obtained CR. The mean follow-up time is 75.5 months and there was no evidence of recurrent disease. Conclusion: The result of this conservative treatment for EST of the vagina is excellent. BEP chemotherapy without surgery should be considered as a good choice of treatment. Close follow up with serial determinations of serum AFP level together with imaging tests and physical examination in the first two years of follow-up are recommended. © 2011 Elsevier Inc.
