Gestational trophoblastic disease (GTD) develops from abnormal cellular proliferation of trophoblasts following fertilization and is categorized as either an hydatidiform mole (HM) or a gestational trophoblastic neoplasia (GTN).


To analyze the clinical characteristics, incidence and treatment outcomes of GTD at Rajavithi Hospital.


Medical records of women diagnosed with GTD at Rajavithi Hospital from January 1, 2001 to December 31, 2010 were retrospectively reviewed. Disease diagnosis, treatment and follow-up data were analyzed.


A total of 329 cases of GTD were reviewed. HM was diagnosed in 167 patients (incidence 2.32 per 1,000 deliveries); 26 patients were lost to follow-up; and 49 of the remaining 141 patients (34.8%) developed post-molar GTN. In multivariable analysis, uterus >16 week size and pre-treatment human chorionic gonadotropin (hCG) level >250,000 mIU/mL were the significant risk factors for developing post-molar GTN. Of 162 patients with GTN (incidence 2.25 per 1,000 deliveries), 15 patients were lost to follow-up, and 116 patients, 29 patients and 2 patients were classified as having low-risk GTN, high-risk GTN and placental site trophoblastic disease respectively. The overall survival rate in the low-risk group was 100% whereas in the high-risk group it was 86.2%. A modified WHO prognostic score of more than five was the significant risk factor for developing resistant GTN.


GTD treatment at Rajavithi Hospital showed excellent clinical outcomes. Uterus >16 weeks size and pre- treatment hCG > 250,000 mIU/mL were the significant risk factors for developing post-molar GTN in HM patients. Classifying GTN patients into low- and high-risk groups was useful in planning treatment and counseling.
