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
- There is no pharmacologic therapy for the mature teratoma.
- Adjuvant Chemotherapy is recommended for all the patients with diagnosed malignant ovarian germ cell tumor, except those with stage 1a, stage 1a and 1b dysgerminoma, and grade 1 immature teratomas.[1][2]
- In those with stage 1a dysgerminoma and immature teratoma, surgery will be curative.
- Platinum-based regimen is currently the most effective management.
- This regimen is as following:
- Bleomycin 30 Unit IV per dose be given on day 1, 8, and 15 of the cycle
- It must be diluted in 50 ml of normal saline (NS) and over 10 minutes.
- Etoposide 100 mg/m2 IV per day be given on days 1-5.
- Cisplatin 20 mg/m2 IV per day be given on Days 1 through 5.
- It must be diluted in 250 ml NS and administer over two hours.
- No aluminum needles or intravenous sets be used for the administration.
- Bleomycin 30 Unit IV per dose be given on day 1, 8, and 15 of the cycle
- This regimen is given every 21 days for three cycles (or four cycles in the presence of bulky residual disease after surgery.
- Factors that should be monitored during the treatment:
- Complete blood count (CBC) weekly during treatment
- Liver function test (LFT) before each treatment cycle
- Creatinin and electrolytes before each treatment cycle
- Pulmonary function test before starting bleomycin and at repeated intervals
- The overall survival rate for the patients treated with this regimen is 87% to 98%.[3][4]
- This regimen is as following:
- Another regimen for the treatment of ovarian germ cell tumors is the combination of Vincristine, dactinomycin, and cyclophosphamide (VAC); however, Platinum-based regimen are now preferred because of a lower relapse rate and shorter treatment time.[5]
Treatment during pregnancy
- In pregnant women, chemotherapy should be postponed at least until the end of the first trimester.[6]
- Etoposide use is associated with teratogenicity during the first trimester of the pregnancy and therefore should be avoided.[7]
- Also its use is associated with neonatal delayed growth and bone marrow suppression.[8]
- Paclitaxel-carboplatin or cisplatin-vinblastine-bleomycin is recommended to be used during the pregnancy.[7]
- Chemotherapy during the second and third trimester of pregnancy has not been observed to be associated with increased risk of fetal abnormalities.[9]
- Miscarriage rate following chemotherapeutic treatment has been reported to be the same as for general population.[10]
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:
- In one study, 83% of cases treated for these tumors, resumed regular period during follow ups.[11]
- In another study, regular menses resumed in 100% of patients within 1 year of chemotherapy completion.[12]
- Infertility rate for women who has been treated chemo-therapeutically for these tumors has been reported between 5% and 10%.[11][13]
Raditherapy
- Not all the ovarian germ cell tumors are radiosensitive.[14]
- Dysgerminoma is a radiosensitive tumor.
- Radiotherapy is not the first option for treating dysgerminoma and it reserved for patients for whom chemotherapy is contraindicated for whatever reason.
- Whole abdominal radiotherapy is used for the treatment of dysgerminoma, however, it may be associated with ovarian failure.[15]
