Overview
An elevated concentration a-fetoprotein (AFP) and b-human chorionic gonadotrophin (b-hCG) are diagnostic of malignant ovarian germ cell tumors.
Ovarian germ cell tumor Laboratory Findings
An elevated concentration a-fetoprotein (AFP) and b-human chorionic gonadotrophin (b-hCG) are diagnostic of malignant ovarian germ cell tumors.[1]
The tumor marker associated with ovarian germ cell tumor subtypes are as follows:[2]
| Ovarian germ cell tumor subtype | Tumor markers expressed |
| Dysgerminoma | |
| Embryonal carcinoma | |
| Endodermal sinus tumor or yolk sac tumors | |
| Polyembryoma | |
| Teratoma |
|
| Choriocarcinoma |
Mature teratoma
- Mature teratoma is associated with increased level of CA 19-9. [3]
- There is a report suggesting a role for increased levels of CA-125 and AFP tumor markers in differentiating the immature teratoma and mature teratoma.[4]
Immature teratoma
Dysgerminoma
- Pure dysgerminoma, usually secret no hormones. However, 5% of tumors are capable of producing B-hCG.[6]
- Multinucleated syncytiotrophoblastic giant cells, in the dysgerminoma, produce B-hCG.
- LDH and ALK-P may be elevated nonspecifically.
Embryonal carcinoma
- They are capable of producing alpha-fetoprotein or human chorionic gonadotropin.[7]
Endodermal sinus tumor
- Yolk sac tumor is associated with increased level of AFP.[8]
Polyembryoma
Non-gestational choriocarcinoma
- They can produce human chorionic gonadotropin.[7]
