From the Guidelines
Yes, germ cell tumors can affect both ovaries and testes. These tumors originate from primitive germ cells, which are the cells that develop into eggs in females and sperm in males. In females, germ cell tumors typically occur in the ovaries and account for about 20-25% of all ovarian neoplasms 1. In males, they most commonly develop in the testes and represent approximately 95% of all testicular cancers 1. The most common types include seminomas (in testes) and dysgerminomas (in ovaries), as well as non-seminomatous tumors like yolk sac tumors, embryonal carcinomas, choriocarcinomas, and teratomas.
Some key points to consider:
- The incidence and age distribution of germ cell tumors differ between males and females, with testicular germ cell tumors being more common in young adult males and ovarian germ cell tumors typically affecting adolescents and young women 1.
- Treatment typically involves surgery to remove the affected gonad, often followed by chemotherapy regimens containing cisplatin, etoposide, and bleomycin for advanced cases 1.
- Radiation therapy may be used in specific situations, and the prognosis can differ between ovarian and testicular germ cell tumors 1.
- Fertility preservation is an important consideration in the treatment of germ cell tumors, particularly in young patients 1.
Overall, germ cell tumors are a significant concern for both males and females, and prompt diagnosis and treatment are essential to improve outcomes.
From the FDA Drug Label
Metastatic Testicular Tumors The usual cisplatin dose for the treatment of testicular cancer in combination with other approved chemotherapeutic agents is 20 mg/m 2IV daily for 5 days per cycle. Metastatic Ovarian Tumors The usual cisplatin dose for the treatment of metastatic ovarian tumors in combination with cyclophosphamide is 75 to 100 mg/m 2IV per cycle once every 4 weeks (DAY 1)
Germ cell tumors can affect both ovaries and testes, as indicated by the treatment of metastatic testicular tumors and metastatic ovarian tumors with cisplatin.
- The drug label mentions the use of cisplatin for the treatment of testicular cancer and ovarian tumors, suggesting that germ cell tumors can occur in both ovaries and testes 2.
From the Research
Germ Cell Tumors Affecting Ovaries and Testes
- Germ cell tumors can affect both ovaries and testes, as they arise from the primordial germ cell and share many similarities 3.
- These tumors can be either benign or malignant, with the majority of ovarian germ cell tumors being represented by mature cystic teratomas 4, 5.
- Malignant germ cell tumors, such as dysgerminoma, yolk sac tumor, embryonal cell carcinoma, and choriocarcinoma, can occur in both ovaries and testes, although the prognosis and treatment recommendations may differ 3, 6.
- The incidence rate of testicular cancer is more than 15 times that of ovarian germ cell tumors, which can affect the knowledge, experience, and evidence available for treatment 3.
- Familial cases of germ cell tumors have been reported, with some families having both male and female members affected by these tumors 6.
- Teratomas are a common form of germ cell tumor, defined histologically as containing tissues derived from all 3 germ cell layers: ectoderm, mesoderm, and endoderm 7.
Comparison of Ovarian and Testicular Germ Cell Tumors
- Ovarian and testicular germ cell tumors have different prognoses, with the 5-year overall survival rate being 85.2% for ovarian germ cell tumors and 98.2% for testicular germ cell tumors 3.
- The staging system and treatment recommendations for ovarian and testicular germ cell tumors are dissimilar, which can affect the outcome for patients with these tumors 3.
- Adopting specific treatment strategies from testicular germ cell tumors, such as de-escalating adjuvant chemotherapy for low-risk patients and implementing more standardized and intensive treatment protocols in cases of relapse, may improve the prognosis for ovarian germ cell tumor patients 3.
