What is this project about?

Identification of Biomarkers for the Diagnosis, Management and Follow-up of Women with Gestational Trophoblastic Disease

Gestational Trophoblastic Disease (GTD) also known as molar pregnancy is a rare disorder affecting one in 600 pregnancies. Most molar pregnancies resolve following uterine evacuation but some progress to malignant disease requiring chemotherapy. The pregnancy hormone, human chorionic gonadotrophin (hCG) is not an ideal biomarker for GTD as it is prone to false positive/negative results.

This project aims to identify more sensitive biomarkers for GTD to allow earlier detection of disease recurrence and progression to malignant disease.

Meet Caroline Joyce, PhD Student, Biomarkers for Gestational Trophoblastic Disease Project

What is involved?

  • National survey of women on the GTD Registry
  • Systematic review on the use of hCG in diagnosis, monitoring and treatment of GTD
  • Audit of molar pregnancy comparing histological and genetic classification
  • Evaluation of commercial hCG immunoassays used in the diagnosis and monitoring of GTD
  • Evaluation of new biomarkers for use in the diagnosis and monitoring of Gestational Trophoblastic Neoplasia (GTN) - placental growth factor (PIGF) and cell free DNA (cfDNA)
  • Qualitative study of General Practitioners as stakeholders engaging with patients on the GTD Registry.
