What this Trial Is About

Researchers are working through the French National Reference Centre of Gestational Trophoblastic Disease to improve how this rare group of pregnancy-related tumors is managed across France. Since 1999, the center has registered and monitored women diagnosed with gestational trophoblastic disease (GTD), including molar pregnancies and related neoplasias, by collaborating with local doctors and specialists. This observational study aims to support patient care through expert review and coordinated follow-up while tracking how diagnoses agree between local and central pathologists. The center operates with a multidisciplinary approach that keeps patients primarily under the care of their local gynecologists. When a molar pregnancy is diagnosed, the local doctor contacts the center to report the case and obtain guidance. The center sends consent forms and information to patients and physicians, and arranges for expert pathologists to review pathology slides centrally. Patients undergo regular blood tests to monitor hCG levels at local labs, with results reviewed weekly by the center to guide ongoing care. If abnormal hCG patterns or more serious trophoblastic tumors are suspected, further imaging and evaluation are conducted to determine appropriate treatment plans. Participants remain primarily under their local physician's care but are closely followed by the center through regular communication and data collection. The study collects weekly hCG data to track disease progression and treatment response, sending updates to physicians at key milestones. The main outcome measured is whether local and central pathologists agree on diagnoses within 18 months. This coordinated approach aims to enhance diagnosis accuracy, treatment decisions, and fertility preservation for women with GTD. Women can expect ongoing monitoring and timely specialist input throughout their care journey.
