Overview
An elevated/reduced concentration of serum/blood/urinary/CSF/other [lab test] is diagnostic of [disease name].
OR
Laboratory findings consistent with the diagnosis of [disease name] include [abnormal test 1], [abnormal test 2], and [abnormal test 3].
OR
[Test] is usually normal for patients with [disease name].
OR
Some patients with [disease name] may have elevated/reduced concentration of [test], which is usually suggestive of [progression/complication].
OR
The laboratory findings associated with ovarian germ cell tumor are serum lactate dehydrogenase (LDH), human chorionic gonadotropin (HCG), CA-125, and alpha-fetoprotein (AFP).[1]
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.[2] The tumor marker associated with ovarian germ cell tumor subtypes are as follows:[1]
| Ovarian germ cell tumor subtype | Tumor markers expressed |
| Dysgerminoma |
|
| Endodermal sinus tumor or yolk sac tumors |
|
| Embryonal Carcinoma |
|
| 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, CA 153, and AFP tumor markers in differentiating the immature teratoma and mature teratoma.[4]
There are no diagnostic laboratory findings associated with [disease name].
Dysgerminoma
- Pure dysgerminomaa, usually secret no hormones. However, 5% of tumors are capable of producing B-hCG.[5]
- Multinucleated syncytiotrophoblastic giant cells, in the dysgerminoma, produce B-hCG.
- LDH and ALK-P may be elevated nonspecifically.
OR
Yolk sac tumor
- Yolk sac tumor is associated with increased level of AFP.[6]
Embryonal carcinoma
- They are capable of producing alpha-fetoprotein or human chorionic gonadotropin.[7]
Choriocarcinoma
- They can produce human chorionic gonadotropin.[7]
An elevated/reduced concentration of serum/blood/urinary/CSF/other [lab test] is diagnostic of [disease name].
OR
[Test] is usually normal among patients with [disease name].
OR
Laboratory findings consistent with the diagnosis of [disease name] include:
- [Abnormal test 1]
- [Abnormal test 2]
- [Abnormal test 3]
OR
Some patients with [disease name] may have elevated/reduced concentration of [test], which is usually suggestive of [progression/complication].
