Gestational trophoblastic disease GTD is a term used for a group of pregnancy-related tumours. These tumours are rare, and they appear when cells in the womb start to proliferate uncontrollably. The cells that form gestational trophoblastic tumours are called trophoblasts and come from tissue that grows to form the placenta during pregnancy. There are several different types of GTD. Hydatidiform moles are benign in most cases, but sometimes may develop into invasive moles, or, in rare cases, into. 29 gestational trophoblastic neoplasia. Neil J. Sebire, MB, MD. Hydatidiform Molar Pregnancy. Changes in the Epidemiology of the Diagnosis of Hydatidiform Mole. Ultrasound in the Detection of Hydatidiform Mole. Management of Hydatidiform Mole. Persistent Gestational Trophoblastic Neoplasia. The term gestational trophoblastic neoplasia GTN encompasses a range of entities including the more common complete CHM and partial PHM hydatidiform mole, invasive mole IM, coexistent complete mole and live fetus, and the rarer malignant entities choriocarcinoma CC and placental site trophoblastic tumor PSTT. Choriocarcinoma, placental site trophoblastic tumor, and epithelioid trophoblastic tumor. The latter four entities are referred to as gestational trophoblastic neoplasia GTN. conditions are aggressive with a propensity to widely metastasize. Gestational trophoblastic disease is a condition of uncertain etiology, comprised of hydatiform mole complete and partial, invasive mole, choriocarcinoma, and placental site trophoblastic tumor. It arises from abnormal proliferation of trophoblastic tissue. Gestational trophoblastic disease GTD results from the abnormal proliferation of trophoblastic tissue and encompasses a wide spectrum of diseases, including: hydatidiform mole complete mole partial mole coexistent molar pregnancy invasive.

You might hear GTDs called gestational trophoblastic disease, gestational trophoblastic tumors, or gestational trophoblastic neoplasia. neoplasia simply means new growth. Most GTDs are benign not cancer and they don't invade deeply into body tissues or spread to other parts of the body. But some are malignant cancerous. Placental-site trophoblastic tumor PSTT is a very rare form of GTDthat develops where the placenta attaches to the lining of the uterus. This tumor most often develops after a normal pregnancy or abortion, but it may also develop after a complete or partial mole is removed. Most PSTTs do not spread to other sites in the body. Gestational Trophoblastic Tumor Staging. Updated: Oct 18, 2019. Gestational trophoblastic neoplasia GTN is staged by the American Joint Committee on Cancer AJCC and the Féderation Internationale de Gynécologie et dObstétrique FIGO based on the criteria below see table 1. The FIGO staging and classification system is more commonly used, since lymph nodes are rarely evaluated in the staging of GTN. Table 1.

METHODS Color Doppler ultrasound was performed in 28 patients with gestational trophoblastic tumors. The vascular morphologic manifestations were recorded, and the peak systolic velocity and resistance index of uterine artery were calculated.
