Placental site trophoblastic tumor is a very rare variant of gestational trophoblastic disease which differs histologically and immunocytochemically from gestational choriocarcinoma. The English language literature includes only 74 reported cases. Seventeen patients have been managed at Charing Cross Hospital with this diagnosis. The median follow-up is 4.6 years, and the 5-year overall surviva...

Indications and outcomes of hysterectomy in women with gestational trophoblastic neoplasia (GTN) were reviewed at Chiang Mai University Hospital, Chiang Mai, Thailand. From January 1998 through December 2008, 18 women underwent simple transabdominal hysterectomy (TAH). Indications for TAH included suspicious lesions confined to the uterus (5), chemoresistant lesions confined to the uterus (7), ...

It is universally recognized that an accurate and precise staging and classification system for gestational trophoblastic neoplasia (GTN) is essential to enable clinicians to assess the prognosis or the risk of patients, to individualize and to optimize their treatment. There have been a variety of staging and classification systems developed by different centres and some are still being used. ...

The World Health Organisation’s (WHO) classification of gestational trophoblastic disease includes complete, partial, invasive and metastatic hydatidiform mole, exaggerated placental site nodule or plaque and two malignant tumoursplacental site trophoblastic tumour and choriocarcinoma [1]. The incidence of gestational trophoblastic disease (GTD) in Sri Lanka according to a hospital based study ...

Gestational trophoblastic neoplasia (GTN) represents a group of diseases characterized by production of human chorionic gonadotropin (hCG). Since non-gestational tumors may occasionally secrete hCG, histopathological diagnosis is important for appropriate clinical management. However, a histopathological diagnosis is not always available. We therefore investigated the feasibility of extracting ...

BACKGROUND Glypican-3 (GPC3) is a membrane-bound heparan sulfate proteoglycan that functions in embryonic cell growth and differentiation and is highly expressed in the placenta. GPC3 is mutated in Simpson-Golabi-Behmel syndrome, which is characterized by tissue overgrowth and an increased risk of embryonal malignancies. GPC3 has also been implicated in sporadic cancer, particularly hepatocellu...

BACKGROUND Preeclampsia is one of the leading causes of maternal and perinatal mortality and morbidity worldwide and its pathogenesis is not totally understood. As a member of the chromosomal passenger complex and an inhibitor of apoptosis, survivin is a well-characterized oncoprotein. Its roles in trophoblastic cells remain to be defined. METHODS The placental samples from 16 preeclampsia pa...

Placental chorioangioma is the most common subtype of non-trophoblastic placental tumors. Other subtypes are very rare and usually associated with an uneventful course of pregnancy. Most chorioangiomas are small and of no clinical significance. Giant chorioangiomas may be associated with serious fetal and maternal complications. So far, no established ultrasound guidelines are available for the...

Choriocarcinoma, a malignancy of trophoblastic cells, is characterized by the secretion of human chorionic gonadotropin (hCG). Choriocarcinoma primarily arises from the fetal (placental) trophoblasts in the setting of a molar pregnancy. Nongestational choriocarcinoma from the ovary or testis is much rarer. Testicular choriocarcinoma is a malignant tumor with great propensity for distant metasta...
