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...

The current symposium contains a selection of papers that were presented at the XVIth World Congress on Gestational Trophoblastic Diseases in Budapest, Hungary, October 16–19, 2011. The Congress was organized under the exceptional leadership of Dr. Vilmos Fulop, the Congress Chairperson, and was extraordinarily successful in showcasing the latest advances in the basic science, population studie...

Measurement of hCG remains today central for diagnosis, treatment and follow-up of gestational trophoblastic diseases (GTD). In order to evaluate this contribution, we conducted a prospective cohort study in the Service of high-risk pregnancy of Rabat Maternity Les Orangers and the Laboratory of Rabat Military Teaching Hospital Mohammed V over a period of eighteen months. 35 patients were inclu...
