AIMS To investigate the pattern of telomerase activity in hydatidiform mole as compared with normal placenta and choriocarcinoma, and to determine the prognostic significance of telomerase activity in hydatidiform mole. METHODS Telomerase activity in 35 cases of hydatidiform mole, 35 normal placentas, one choriocarcinoma sample, and two choriocarcinoma cell lines (JAR, JEG3) was determined us...

BACKGROUND Gestational trophoblastic disease refers to a spectrum of rare benign and malignant gynecologic disorders whose pathogenesis is not well understood. Recent studies from China and the United States have raised the hypothesis that long-term use of oral contraceptives before conception may increase the risk of gestational trophoblastic tumors. A multicenter case-control study of gestati...

background: distinction of hydatidiform moles (hms) from non-molar abortions and sub-classification of hms are important for clinical practice; yet, diagnosis based solely on morphology is affected by interobserver variability. the objective of this study was to determine the role of dna flow cytometry in distinguishing molar from non-molar pregnancies. materials and methods: this retrospective...

Gestational trophoblastic disease has been reported to be responsive to chemotherapy, with a 90% cure rate. Several factors place patients at high risk of experiencing treatment failure with single agent chemotherapy. Choriocarcinoma following term pregnancy is very rare and associated with a poor prognosis and a mortality rate of 33-40%. We present a rare case of cutaneous metastasis of chorio...

Gestational trophoblastic neoplasia (GTN) includes the abnormal pregnancies complete (CHM) and partial hydatidiform mole (PHM) and the malignant gestational trophoblastic tumours (GTT) invasive mole (IM), choriocarcinoma, placental site trophoblastic tumour (PSTT) and epithelioid trophoblastic tumour (ETT). While many genetic studies have been performed in both CHM and PHM, similar studies of t...

early recognition of gestational trophoblastic neoplasm (gtn) will maximize the chances of cure with chemotherapy but some patients present with many different symptoms months or even years after the causative pregnancy making diagnosis difficult. clinicians should be aware of the possibility of gtn in any reproductive age woman with bizarre central nervous system, gastrointestinal, pulmonary s...

Gestational trophoblastic disease is an abnormality of pregnancy that encompasses a group of diseases that differ from each other in their propensity for regression, invasion, metastasis, and recurrence. In the past, it was common for patients with molar pregnancy to present with marked symptoms: copious bleeding; theca lutein cysts; uterus larger than appropriate for gestational age; early pre...

BACKGROUND Invasive mole is responsible for most cases of localized gestational trophoblastic neoplasia. Gestational trophoblastic disease describes a number of gynecologic tumors that originate in trophoblastic layer including hydatidiform mole (complete or partial), invasive mole, choriocarcinoma, placental site trophoblastic tumor and epitheloid trophoblastic tumor. Invasive mole may arise f...
