Incidence and outcome of gestational trophoblastic disease in lower Egypt

BACKGROUND: Gestational trophoblastic disease (GTD) defines a spectrum of proliferative disorders of trophoblastic epithelium of the placenta. Incidence, risk factors, and outcome may differ from one country to another. OBJECTIVE: To describe incidence, patient characteristics, treatment modalities, and outcome of GTD at Mansoura University which is a referral center of Lower Egypt. METHODS: An observational prospective study was conducted at the GTD Clinic of Mansoura University. The patients were recruited for 12 months from September 2015 to August 2016. The patients' characteristics, management, and outcome were reported. RESULTS: We reported 71 clinically diagnosed GTD cases, 62 of them were histologically confirmed, 58 molar (33 CM and 25 PM) in addition to 4 initially presented GTN cases. Mean age of the studied cases was 26.22 years ± 9.30SD. Mean pre-evacuation hCG was 136170 m.i.u/ml ±175880 SD. Most of the cases diagnosed accidentally after abnormal sonographic findings (53.2%). Rate of progression of CM and PM to GTN was 24.2% and 8%, respectively. CONCLUSION: The incidence of molar pregnancy and GTN in our locality was estimated to be 13.1 and 3.2 per 1000 live births respectively. We found no significance between CM and PM regarding hCG level, time to hCG normalization, and progression rate to GTN.
