Gestational trophoblastic disease (GTD)

Published: 22/12/2011

Gestational trophoblastic disease (GTD) is a group of conditions that may occur when a pregnancy doesn’t develop properly, and includes complete and partial molar pregnancy. GTD is an uncommon condition. For approximately every 700 pregnancies which end with a live baby, there will be one pregnancy which develops GTD.

This information is for you if you’ve been diagnosed with GTD. It may also be helpful if you’re a partner, relative or friend of someone in this situation. The patient information leaflet covers:

  • What GTD and molar pregnancy are
  • When a molar pregnancy might be suspected
  • What happens when a molar pregnancy is suspected
  • Follow-up after treatment and why this is important
  • Information about gestational trophoblastic neoplasia (GTN), which can sometimes develop after GTD
  • Information about future pregnancies

This patient information leaflet was developed by the RCOG Patient Information Committee. It's based on the RCOG clinical guideline Management of Gestational Trophobastic Disease, which includes a full list of the sources of evidence we used.
