The beta-subunit of chorionic gonadotrophin as a tumour marker in gestational trophoblastic disease. 1980

S K Khoo, and B Daunter

The clinical usefulness of the serum level of the beta subunit by radioimmunoassay was evaluated in 96 patients with gestational trophoblastic disease. The measurement of the hormone-specific beta subunit has allowed a better understanding of the activity of the various types of disease, with a correlation between the initial serum levels and the different subtypes of hydatidiform mole, and the ability to predict the development of malignant sequelae. The phenomenon of trophoblastic persistence after uterine evacuation was confirmed: although the half-life of the beta subunit was 4 days during the early phase, there was an average period of 8 weeks before levels fell to negative and 12 weeks was the limit for spontaneous regression. The serial beta subunit levels were found to provide an accurate indication of the clinical course of the disease in untreated and treated patients, and treatment could be withheld after 3 consecutive weekly negative values.

D009362	Neoplasm Metastasis	The transfer of a neoplasm from one organ or part of the body to another remote from the primary site.	Metastase,Metastasis,Metastases, Neoplasm,Metastasis, Neoplasm,Neoplasm Metastases,Metastases
D011247	Pregnancy	The status during which female mammals carry their developing young (EMBRYOS or FETUSES) in utero before birth, beginning from FERTILIZATION to BIRTH.	Gestation,Pregnancies
D011644	Puerperal Disorders	Disorders or diseases associated with PUERPERIUM, the six-to-eight-week period immediately after PARTURITION in humans.	Disorder, Puerperal,Disorders, Puerperal,Puerperal Disorder
D011863	Radioimmunoassay	Classic quantitative assay for detection of antigen-antibody reactions using a radioactively labeled substance (radioligand) either directly or indirectly to measure the binding of the unlabeled substance to a specific antibody or other receptor system. Non-immunogenic substances (e.g., haptens) can be measured if coupled to larger carrier proteins (e.g., bovine gamma-globulin or human serum albumin) capable of inducing antibody formation.	Radioimmunoassays
D002822	Choriocarcinoma	A malignant metastatic form of trophoblastic tumors. Unlike the HYDATIDIFORM MOLE, choriocarcinoma contains no CHORIONIC VILLI but rather sheets of undifferentiated cytotrophoblasts and syncytiotrophoblasts (TROPHOBLASTS). It is characterized by the large amounts of CHORIONIC GONADOTROPIN produced. Tissue origins can be determined by DNA analyses: placental (fetal) origin or non-placental origin (CHORIOCARCINOMA, NON-GESTATIONAL).	Choriocarcinomas
D005260	Female		Females
D006063	Chorionic Gonadotropin	A gonadotropic glycoprotein hormone produced primarily by the PLACENTA. Similar to the pituitary LUTEINIZING HORMONE in structure and function, chorionic gonadotropin is involved in maintaining the CORPUS LUTEUM during pregnancy. CG consists of two noncovalently linked subunits, alpha and beta. Within a species, the alpha subunit is virtually identical to the alpha subunits of the three pituitary glycoprotein hormones (TSH, LH, and FSH), but the beta subunit is unique and confers its biological specificity (CHORIONIC GONADOTROPIN, BETA SUBUNIT, HUMAN).

D006828	Hydatidiform Mole	Trophoblastic hyperplasia associated with normal gestation, or molar pregnancy. It is characterized by the swelling of the CHORIONIC VILLI and elevated human CHORIONIC GONADOTROPIN. Hydatidiform moles or molar pregnancy may be categorized as complete or partial based on their gross morphology, histopathology, and karyotype.

D014328	Trophoblastic Neoplasms	Trophoblastic growth, which may be gestational or nongestational in origin. Trophoblastic neoplasia resulting from pregnancy is often described as gestational trophoblastic disease to distinguish it from germ cell tumors which frequently show trophoblastic elements, and from the trophoblastic differentiation which sometimes occurs in a wide variety of epithelial cancers. Gestational trophoblastic growth has several forms, including HYDATIDIFORM MOLE and CHORIOCARCINOMA.
