[Clinical Study to Determine the Dose Intensity of BEP Chemotherapy for Ovarian Malignant Germ Cell Tumors]

A standard regimen for ovarian malignant germ cell tumors is bleomycin, etoposide, cisplatin(BEP)chemotherapy. Adherence to a treatment schedule of every 21 days has been reported to be important. However, the incidence of febrile neutropenia( FN)and the optimaluse of granulocyte-colony stimulating factor(G-CSF)are unclear because of the low incidence of ovarian malignant germ cell tumors. We experienced 2 cases of ovarian malignant germ cell tumors that received BEP therapy after fertility-conserving surgery. In 1 case, we delayed drug administration in the first cycle because of FN. However, in order to maintain dose intensity(DI), we performed chemotherapy every 21 days by shortening the rest period. Myelosuppression may be severe in the first cycle of BEP therapy; however, it may be possible to adhere to the treatment schedule by using primary prophylactic administration of G-CSF.
