Gestational Trophoblastic Disease: Statistics

Approved by the Cancer.Net Editorial Board, 02/2022

ON THIS PAGE: You will find information about the number of people who are diagnosed with gestational trophoblastic disease (GTD) each year. You will also read general information on surviving the disease. Remember, survival rates depend on several factors. Use the menu to see other pages.

Overall, GTD is rare. GTD occurs in about 110 to 120 per 100,000 pregnancies in the United States. Most of these are molar pregnancies, which frequently affect Asian, Hispanic, and Native American women. Choriocarcinoma occurs in about 2 to 7 pregnancies out of every 100,000 pregnancies in the United States.

However, the prognosis for people with all types of GTD is good, even if the disease has spread to distant organs. Prognosis is the chance of recovery. Cure rates for low-risk gestational trophoblastic neoplasia (GTN) are almost 100% with chemotherapy. Even high-risk GTN cure rates can be as high as 75% with chemotherapy.

It is important to remember that statistics on the survival rates for people with GTD are an estimate. The estimate comes from annual data based on the number of people with GTD in the United States. Talk with your doctor if you have any questions about this information. Learn more about understanding statistics.
