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. ...

It is just 100 years since Marchand [1] identified choriocarcinoma as a tumour arising from placental villous trophoblast. Earlier description of similar tumours failed to identify their tissue of origin. Gestational Trophoblastic Disease (GTD) is the terminological umbrella now used to span the spectrum of cellular proliferations ranging from villous forms of hydatiform mole through invasive m...

•Gestational trophoblastic neoplasia can arise during the first trimester originating from trophoblasts of concurrent pregnancy.•Intraplacental choriocarcinoma can be developed from trophoblasts of a previous pregnancy.

Background: Methotrexate is used in the treatment of Low-risk Gestational Trophoblastic Neoplasia. The purpose of this study was to compare the therapeutic responses and side effects of two therapeutic methods which were prescribed for patients suffering from Low-risk Gestational Trophoblastic Neoplasia. One method was the daily use of Methotrexate-Folic Acid (for 8 da...

Gestational trophoblastic disease describes a number of gynaecological tumours that originate in the trophoblast layer, including hydatidiform mole (complete or partial), placental site trophoblastic tumour, choriocarcinoma and gestational trophoblastic neoplasia (GTN). Invasive moles are responsible for most cases of localized GTN. Two cases of GTN previously reported in the literature exhibit...

Invasive mole is a benign gestational trophoblastic disease that arises from the myometrial invasion of any gestational event via direct extension through tissue or vascular structures. Invasive mole (and other gestational trophoblastic diseases) may present with life-threatening complications including uterine perforation, excessive bleeding, acute hemoperitoneum, and abdominal pain. We report...

Introduction. Gestational trophoblastic disease represents a distinguished group of disorders that are derived from placental tissue aroused abnormal fertilization. Choriocarcinoma is malignant human chorionic gonadotropin-producing epithelial tumor arising villous trophoblast. The choice the chemotherapy regime based on International Federation Gynecology and Obstetrics stage World Health Orga...

Placental site trophoblastic tumor (PSTT) is a rare type of gestational trophoblastic neoplasia (GTN). It is rising from the abnormal proliferation of intermediate trophoblastic cells with occasional multinuclear giant cells, with the potential for local invasion and metastasis. For its untypical and changeable clinical characteristics, the diagnosis and management are still poorly understood. ...
