What Are the Key Statistics About Gestational Trophoblastic Disease?

Gestational trophoblastic disease (GTD) occurs in about 1 pregnancy out of 1,000 in the United States. Most of these are hydatidiform moles.

Choriocarcinoma , a malignant form of gestational trophoblastic disease (GTD), is even less common, affecting around 2 to 7 of every 100,000 pregnancies in the United States.

Choriocarcinoma and other forms of GTD are more common in many Asian and African countries.

Overall, gestational trophoblastic tumors account for less than 1% of female reproductive system cancers.

Cure rates depend on the type of GTD and its stage, as described in Treatment of Gestational Trophoblastic Disease, by Type and Stage.
