Overview

Adjuvant Chemotherapy is recommended for all the patients with diagnosed malignant ovarian germ cell tumor, except those with stage 1a, stage 1a, 1b dysgerminoma, and grade 1 immature teratomas. The platinum-based regimen is currently the most effective management. Among ovarian germ cell tumors, only dysgerminoma is radiosensitive. Radiotherapy is not anymore the first option of treatment for dysgerminoma considering its association with ovarian failure development.

Medical Therapy

Treatment during pregnancy

Chemotherapy for malignant ovarian germ cell tumors and ovarian function

The long term effects of chemotherapy on ability of ovary for future pregnancies has been studied and the results are as following:

Raditherapy
