Kim, Shin, Moon, Park, Kim, Lee, Kim, Kim, Kim, and Nam: Outcomes after bleomycin, etoposide and cisplatin combination chemotherapy in patients with ovarian yolk sac tumor

Abstract

Objective

The aim of this study was to evaluate the oncologic and reproductive outcomes of patients with ovarian yolk sac tumor after bleomycin, etoposide, cisplatin (BEP) chemotherapy following surgery.

Methods

Of 145 patients with histologically confirmed malignant ovarian germ cell tumor, 43 had yolk sac tumor and received BEP chemotherapy after surgery. A retrospective analysis of these patients was performed.

Results

The mean age of 43 patients was 24.8 years (range, 7 to 59 years). Thirty eight patients were nulliparous. Of 179 BEP chemotherapy cycles, grade 1~2 hematologic and non-hematologic adverse events occurred in 46 cycles in 21 patients. Thirty nine patients showed complete remission, 1 patient showed partial remission, and 3 patient had progressive disease during BEP chemotherapy. After median follow-up time of 57 months (range, 3 to 153 months), 5 patients had recurrent disease and three of them died of disease. The 5-year recurrence free survival rate and overall survival rate were 86% and 94%, respectively. After chemotherapy, all but one premenarchal patients had normal menstruation. Of them 5 patients tried to conceive and 3 of them succeeded in pregnancy.

Conclusion

BEP chemotherapy was very safe and effective in patients with ovarian yolk sac tumor. Survival outcomes are excellent and reproductive outcomes are promising after BEP chemotherapy.
