Gestational trophoblastic disease

What is gestational trophoblastic disease?

GTD is a term that describes a group of growths that can occur inside the uterus after sperm and egg join (conception or fertilization), but do not become a fetus. Although very rare, these growths can become cancerous and spread to other parts of the body.

Types of gestational trophoblastic disease

There are two main types of GTD: hydatidiform mole (HM), also called molar pregnancy, and gestational trophoblastic neoplasia (GTN).

Signs and symptoms of gestational trophoblastic disease

Gestational trophoblastic disease (GTD) and choriocarcinoma, a type of gestational trophoblastic neoplasia (GTN), often show the signs and symptoms of a normal pregnancy.

  • Vaginal bleeding after delivery, miscarriage or abortion that lasts longer than six weeks and shows no signs of stopping
  • An enlarged uterus
  • Pelvic pain or pressure
  • Severe nausea and vomiting
  • High blood pressure with headache and swelling of feet and hands early in pregnancy
  • Anemia, which can cause fatigue, shortness of breath, dizziness, and a fast or irregular heartbeat
  • Overactive thyroid

Signs of Choriocarcinoma

Choriocarcinoma is a cancerous form of GTD and is the most aggressive type of GTN, so it is important to contact your doctor if you experience any of the following symptoms after an abortion, miscarriage, ectopic pregnancy, or full-term pregnancy.

  • Vaginal bleeding that lasts longer than six weeks and doesn’t show signs of slowing down
  • Neurologic (brain) symptoms or cough, which could mean that the cancer has spread

What causes gestational trophoblastic disease?

Gestational trophoblastic disease (GTD) is a term for growths in the uterus that occur after conception. GTD is caused by conception (when sperm and egg join) and can develop during the early stages of a normal or ectopic pregnancy, or following a miscarriage or abortion.

What causes choriocarcinoma?

Choriocarcinoma is a cancerous form of GTD that most often develops from a molar pregnancy (also called hydatidiform mole or HM).
