Pleomorphic carcinoma of the lung with high serum beta.

OBJECTIVES: To derive a model and examine the performance of first-trimester combined screening by maternal age, fetal nuchal translucency (NT) thickness and maternal serum free beta-human chorionic gonadotropin (beta-hCG) and pregnancy-associated plasma protein-A (PAPP-A).

Serum free beta-human chorionic gonadotropin

Ectopic secretion of beta-human chorionic gonadotropin is considered a poor prognostic marker in epithelial tumors. However, very few cases have been reported in sarcomas. We present the case of a 26-year-old female who presented with a metastatic osteosarcoma. She underwent usual testing prior to starting treatment and was found to have elevated levels of beta-human chorionic gonadotropin.

Define human chorionic gonadotrophin. human chorionic gonadotrophin synonyms, human chorionic gonadotrophin pronunciation, human chorionic gonadotrophin translation, English dictionary definition of human chorionic gonadotrophin. Noun 1. human chorionic gonadotrophin - hormone produced early in pregnancy by the placenta; detection in the urine and serum is the basis for one kind of.Abstract. The aim of our study was to compare three protocols for second-trimester maternal serum screening for Down's syndrome in the same serum samples, using two triple tests (total human chorionic gonadotrophin (HCG), alpha-fetoprotein, unconjugated oestriol; and free beta-HCG, alpha-fetoprotein, unconjugated oestriol) and a double test (free beta-HCG and alpha-fetoprotein).Posts about human chorionic gonadotropin beta written by Melissa Marrero.


Human chorionic gonadotropin (hCG) is a glycoprotein secreted by the placenta during pregnancy that consists of an alpha and beta subunit. The alpha subunit is structurally similar to the alpha subunits of FSH, LH and TSH. The beta subunit is distinct for hCG. The release of hCG into maternal circulation begins with embryo implantation 5 to 7 days after fertilization.Test Code BHCG Beta-Human Chorionic Gonadotropin, Quantitative, Serum Reporting Name Beta-HCG, Quantitative, S Useful For. Monitoring patients for retained products of conception Aiding in the diagnosis of gestational trophoblastic disease (GTD), testicular tumors, ovarian germ cell tumors, teratomas, and, rarely, other human chorionic gonadotropin (hCG)-secreting tumors Serial measurement of.

Serum free beta-human chorionic gonadotropin

Test Code HCGTUMOR (BHCG) Beta-Human Chorionic Gonadotropin, Quantitative, Serum. tumors may produce disproportionate quantities of free alpha-subunits or, more commonly, free beta-subunits. Assays that detect both intact hCG and free beta-hCG, including this assay, tend to be more sensitive in detecting hCG-producing tumors. With successful treatment of hCG-producing tumors, hCG levels.

Serum free beta-human chorionic gonadotropin

Human chorionic gonadotropin (hCG) is a hormone produced by the placenta after implantation. The presence of hCG is detected in some pregnancy tests (HCG pregnancy strip tests).Some cancerous tumors produce this hormone; therefore, elevated levels measured when the patient is not pregnant may lead to a cancer diagnosis and, if high enough, paraneoplastic syndromes, however, it is not known.

Serum free beta-human chorionic gonadotropin

Doctors give trusted answers on uses, effects, side-effects, and cautions: Dr. Munshower on beta human chorionic gonadotrophin: Hcg is also produced by molar pregnancies and choriocarcinoma, a type of cancer that is similar to pregnancy tissue. Outside of these, its just pregnancy.

Serum free beta-human chorionic gonadotropin

A recombinant therapeutic agent which is chemically identical to or similar to the endogenous glycoprotein hormone human chorionic gonadotropin (HCG). HCG binds to cells of the corpus luteum, thereby stimulating progesterone production and helping to maintain a secretory endometrium. (NCI04).

Serum free beta-human chorionic gonadotropin

The human chorionic gonadotropin (hCG) discriminatory zone--the maternal serum (beta)-hCG range above which a gestational sac should be consistently visible by ultrasonography (US) in a normal pregnancy--should not be used to determine the management of a hemodynamically stable patient who is suspected of having an ectopic pregnancy, according to this retrospective study.

Serum free beta-human chorionic gonadotropin

Beta-human chorionic gonadotropin (hCG)-secreting choriocarcinomas are rare, rapidly growing, highly invasive malignant tumors that present most often in the uterus after pregnancy or abortion, as they are remnants from trophoblastic or totipotent germ cells .Extragonadal sites that have been reported include the gastrointestinal tract, liver, lung, breast, prostate, urinary bladder, and nose.

Serum free beta-human chorionic gonadotropin

Human chorionic gonadotropin (hCG) is a hormone produced by the placenta of a pregnant woman. Early in pregnancy, the level of hCG increases in the blood and is eliminated in the urine.A pregnancy test detects hCG in the blood or urine and confirms or rules out pregnancy. During the early weeks of pregnancy, hCG is important in maintaining function of the corpus luteum.
