Gestational Trophoblastic Disease: Statistics

Approved by the Cancer.Net Editorial Board, 06/2016

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

Overall, GTD is rare and often curable. In the United States, GTD accounts for less than 1% of all cancers that start in a woman's reproductive system, which is a grouping called gynecologic cancers. GTD occurs in about 1 out of every 1,000 to1,500 pregnancies in the United States. Most of these are molar pregnancies. Choriocarcinoma occurs in about 2 to 7 pregnancies out of every 100,000 pregnancies in the United States. Overall, GTD is more common in other parts of the world, including Asia and Africa.

Nearly all women with a molar pregnancy or low-risk gestational trophoblastic neoplasia (GTN) can be cured, often using fertility-sparing surgery alone. A placental site trophoblastic tumor can often be cured, particularly if it is found before it spreads outside the uterus. Even with faster-growing GTN, cure rates are as high as 80% to 90%, with intensive treatment.

It is important to remember that statistics on how many women survive this type of disease are an estimate. The estimate comes from data based on women with GTD in the United States each year. So, your own risk may be different. Doctors cannot say for sure how long any woman will live with GTD. Learn more about understanding statistics.
