In partial molar pregnancies, the trophoblast cells have three sets of chromosomes (triploid). Two sperm are believed to fertilise the ovum at the same time, leading to one set of maternal and two sets of paternal chromosomes. Around 10% of partial moles are tetraploid or mosaic in nature. There is usually evidence of fetal tissue or fetal blood cells in a partial molar pregnancy. An embryo may...

BACKGROUND Molar pregnancy represents a significant burden of disease on the spectrum of Gestational Trophoblastic Disease (GTD). The incidence appears to be quite high in South Asia. The objective of this study was to determine the frequency of GTD, and clinical presentation, management and outcome of patients with molar pregnancy. METHODS This retrospective, descriptive study was conducted ...

OBJECTIVE To provide standards for the diagnosis and treatment of patients with hydatidiform mole and gestational trophoblastic tumours (GTT). OPTIONS Prognostic factors useful for treatment decisions in GTT are defined with patients classified as low-, medium-, and high-risk groups. OUTCOMES Improved mortality and morbidity. EVIDENCE Evidence was gathered using Medline for relevant studi...

Patients diagnosed with molar pregnancy are treated by either suction curettage or hysterectomy, depending on their desire to preserve fertility. We use single-agent chemotherapy, preferably methotrexate, to treat low- or moderate-risk persistent trophoblastic tumors. High-risk patients who have metastatic disease are treated primarily with combination chemotherapy and, as indicated, adjuvant r...

It is over 100 years since Felix Marchand identified choriocarcinoma as a tumor arising from placental villous trophoblast. In 1956, Hertz etal 1 first reported the cure of a patient with metastatic choriocarcinoma using chemotherapy. The next decade saw Hertz and colleagues at the National Institute of Health, Brewer in Chicago and Bagshawe in London develop the chemotherapeutic approach to ge...

estational trophoblastic disease includes following forms of growth disturbance of the human trophoblast: hydatiform mole, invasive mole, choriocarcinoma and placental site trophoblastic tumors. Term gestational trophoblastic disease is applied to the letter three conditions. Diagnosis and decision to institute treatment are sometimes undertaken without histopathological finding. Gestational tr...

Background—The p21 gene mediates growth arrest by inhibiting G1 cyclin dependent kinases and has been considered as a downstream eVector of the tumour suppressor gene p53. Aim—To analyse the role of p21 in gestational trophoblastic disease. Methods—The immunohistochemical expression of p21 gene was measured in 33 placentas, 28 partial hydatidiform moles, 54 complete hydatidiform moles, and 13 c...

The abnormal pregnancies complete and partial hydatidiform mole are genetically unusual, being associated with two copies of the paternal genome. Typical moles (CHMs) diploid androgenetic, while (PHMs) diandric triploids. While diagnosis can usually be made on basis morphology, ancillary techniques that exploit their unusual genetic origin used to facilitate diagnosis. Genotyping p57 immunostai...
