Like any elevated tumor marker, elevated AFP by itself is not diagnostic, only suggestive. Tumor markers are used primarily to monitor the result of a treatment (e.g. chemotherapy). If levels of AFP go down after treatment, the tumor is not growing. In the case of babies, after treatment AFP should go down faster than it would normally. A ...

For example, tumor markers like Ki-67 can be used to choose form of treatment or in prognostics but are not useful to give a diagnosis, while other tumor markers have the opposite functionality. Therefore it's important to follow the guidelines of the specific tumor marker. Tumor markers are mainly used in clinical medicine to support a ...
Human chorionic gonadotropin is a glycoprotein composed of 237 amino acids with a molecular mass of 36.7 kDa, approximately 14.5kDa αhCG and 22.2kDa βhCG. [4]It is heterodimeric, with an α (alpha) subunit identical to that of luteinizing hormone (LH), follicle-stimulating hormone (FSH), thyroid-stimulating hormone (TSH), and a β (beta) subunit that is unique to hCG.
Serum tumor marker test: For GTN, the blood is checked for the level of β-hCG, a hormone that is made by the body during pregnancy. β-hCG in the blood of a woman who is not pregnant may be a sign of GTN and also helpful tests to monitor a woman’s recovery during and after treatment. Placental side trophoblastic tumor (PSTT) is ...
Choriocarcinoma is a malignant, trophoblastic [1] cancer, usually of the placenta. It is characterized by early hematogenous spread to the lungs. It belongs to the malignant end of the spectrum in gestational trophoblastic disease (GTD). It is also classified as a germ cell tumor and may arise in the testis or ovary.
The most common abnormality the test can screen is trisomy 21 (Down syndrome).In addition to Down syndrome, the triple and quadruple screens assess risk for fetal trisomy 18 also known as Edwards syndrome, open neural tube defects, and may also detect an increased risk of Turner syndrome, triploidy, trisomy 16 mosaicism, fetal death, Smith–Lemli–Opitz syndrome, and steroid sulfatase ...
Persistent elevation of serum hCG levels after a non molar pregnancy (i.e., normal pregnancy [term pregnancy], or preterm pregnancy, or ectopic pregnancy [pregnancy taking place in the wrong place, usually in the fallopian tube], or abortion) always indicate persistent GTD (very frequently due to choriocarcinoma or placental site trophoblastic ...
