background: nowadays, the first step in treatment of ectopic pregnancy (ep) is medical treatment. medical treatment with methotrexate (mtx) for ep is safe and effective method without the risks associated with the surgical procedure. but there are controversies between studies for which patients will respond better to medical treatment. objective: the aim of the present study was to investigate...

Aim. To analyse the levels of serum beta-human chorionic gonadotropin (β-hCG) and pregnancy-associated plasma protein A (PAPP-A) in pregnant women without fetal chromosomal abnormalities with trisomy 21 (Down syndrome) or 18 (Edwards syndrome). Materials Methods. We performed a retrospective analysis biochemical parameters 1214 who had previously undergone karyotyping as part prenatal postnatal...

  Background : Gestational trophoblastic neoplasia (GTN) disease is excessive and inappropriate proliferation of trophoblast after termination of the pregnancy. Many attempts have been made to improve follow-up procedures, but no studies have evaluated Human Chorionic Gonadotrophin (HCG) as a post treatment indicator. Thus we aimed to know β-HCG variability in post treatment pregnancies.   Meth...

BACKGROUND Solitary fibrous tumors are rare tumors of mesenchymal origins, most commonly seen arising from the pleural lining of the lungs. These are generally benign tumors, which in rare cases have been identified to be associated with multiple para-neoplastic syndromes. CASE REPORT This is a case of a solitary fibrous tumor of the pleura in a 49 year old female which was found to be associ...

OBJECTIVE To establish clearance curves for serum β -hCG in women with successfully expectantly managed tubal ectopic pregnancies. DESIGN Retrospective cohort study. Non- viable tubal ectopic pregnancy was diagnosed on transvaginal ultrasound. If initial serum β hCG was less than 5000 IU/L and patients were asymptomatic, expectant management was offered. Patients underwent serial β hCG measur...

Human chorionic gonadotropin β (β-hCG) is a well-known and accurate marker for the diagnosis and monitoring of pregnancy, trophoblastic tumors and ovarian germ cell tumors. Recently, β-hCG has been found to be closely related to poor prognosis and metastasis in various other malignant tumors, while its role and mechanism in ovarian cancer is still unclear. In the present study, lentiviral‑media...

BACKGROUND Anaplastic thyroid carcinoma (ATC) is a rare, aggressive malignancy with a median survival of five months. Multimodality treatment is associated with some improvement in survival, but patients are only infrequently curable. Although β-hCG secretion has been reported in many neoplasms, it has never been described in ATC. The objectives of this study were to report a case of β-hCG-secr...

BACKGROUND Pathological examination combined with tumor markers has become a standard for the diagnosis of intracranial germ cell tumors (ICGCTs), but the current concept of 'secreting germ cell tumors' and three empirically highly specific diagnostic criteria (β-hCG ≥ 50 IU/L or αFP ≥ 10 ng/mL; β-hCG ≥ 100 IU/L or αFP ≥ 50 ng/mL; β-hCG > 50 IU/L or αFP > 25 ng/mL) are not based upon pathology ...
