Gestational Trophoblastic Disease
Gestational trophoplastic disease (GTD) is a group of tumors that develop from the abnormal growth of cells inside the uterus (womb) that would normally develop into the placenta (the organ that passes nutrients from the mother to the fetus) during pregnancy.
Most GTD is benign (not cancer) and does not invade into body tissues or spread to other parts of the body, however, some are malignant (cancerous). Gestational trophoblastic neoplasia (GTN) is a type of gestational trophoblastic disease (GTD) that is almost always malignant. GTDs are rare tumors. The main types of GTD include:
- Hydatidiform mole (molar pregnancy) – complete or partial
- Gestational trophoblastic neoplasia
- Invasive mole
- Placental-site trophoblastic tumor
- Epithelioid trophoblastic tumor
All types of GTD can be treated and treatment often results in a complete cure. The treatment for GTD depends on the specific type of tumor, stage, and other factors.
