CASE A 25-year-woman who had had a complete hydatidiform mole 6 months earlier presented with a 6-week history of secondary amenorrhea. Serum human chorion...
متن کاملMolecular genotyping of placental site and epithelioid trophoblastic tumours; female predominance.
OBJECTIVE To investigate a large series of placental site trophoblastic tumours (PSTT) and epithelioid trophoblastic tumours (ETT) and determine the relationship between their development and the type and sex of both the immediately antecedent and causative pregnancies. METHODS The antecedent pregnancy was determined from patient records in 92 cases with a confirmed diagnosis of PSTT, ETT or ...
متن کاملThe risk of post-molar gestational trophoblastic neoplasia is higher in heterozygous than in homozygous complete hydatidiform moles.
BACKGROUND Complete hydatidiform mole (CHM) is a high-risk pregnancy for gestational trophoblastic neoplasia (GTN). Patients with CHM have a 10-30% chance of trophoblastic sequelae. CHM includes androgenic homozygous (monospermic) and androgenic heterozygous (dispermic) moles. It is controversial whether the risk of GTN is higher with heterozygous than with homozygous CHM. A prospective cohort ...
متن کاملHuman chorionic gonadotrophin as an indicator of persistent ges-tational trophoblastic neoplasia
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...

Introduction The successful development of chemotherapy enabled a fertilitysparing treatment for patients with trophoblastic neoplasia. After disease remission, the outcome of a subsequent pregnancy becomes a great concern for these women.
