Although immunohistochemical examination is not always needed in routine for the diagnosis of clear cell type EOC, to distinguish from other tumors, especially germ cell tumors, or to provide the better way to monitor therapeutic response or to evaluate the disease status, immunostaining, including GPC3, HNF-1 beta, CD30, cytokeratin 7 or 20, and AFP is taken into account.
By establishing sensitive nested reverse transcription-PCRs for the detection of mRNA of alpha-fetoprotein (AFP) and beta human chorionic gonadotropin (betahCG), we investigated the presence of circulating tumor cells in the peripheral blood of 119 patients with germ-cell tumor.
Thus, AFP in germ cell tumors is explained by the development of the yolk sac visceral endoderm (YSVE) in teratocarcinomas, since YSVE is the first site of AFP synthesis in the embryo.
Background Measurement of α-fetoprotein (AFP) concentrations in the serum of infants is useful for the management of testicular germ cell tumors, hepatoblastoma and hepatocellular carcinoma.
We recommend that all males with KS and early sexual development or with "normal" testicular growth be screened with measurement of germ cell tumor markers including beta-subunit of human chorionic gonadotropin and alpha-fetoprotein.
Persistently elevated alpha-fetoprotein associated with chronic hepatitis B during chemotherapy for malignant ovarian germ cell tumors: a case series and a review of the literature.
Hereditary persistence of alpha-fetoprotein (HPAFP) should be considered in both children and adults with unexplained and persistent elevation of AFP e.g., those screened for hepatocellular carcinoma or diagnosed for germ cell tumor.
Preoperative serum alpha-fetoprotein (AFP) levels were reviewed in germ cell tumor (GCT) cases and analyzed to predict malignancy in various age groups.
The prognostic information provided by alpha-fetoprotein and human chorionic gonadotrophin in the management of germ cell tumor (GCT) patients is a biochemical reflection of tumor differentiation.
