Subsequent pregnancy outcomes in patients with molar pregnancy and persistent gestational trophoblastic neoplasia

To evaluate the subsequent reproductive outcomes in patients with complete and partial molar pregnancy and gestational trophoblastic neoplasia (GTN) at the New England trophoblastic Disease Center between June 1, 1965, and December 31, 2007.

Questionnaires regarding subsequent pregnancies were mailed to all patients with current mailing addresses at the New England Trophoblastic Disease Center.

The subsequent reproductive outcomes in patients with complete and partial molar pregnancies and persistent GTN were in general the same as those in the general population. However, after an episode of molar pregnancy the incidence of molar pregnancy in a later gestation was approximately 1%. Additionally, after successful chemotherapy for GTN, the incidence of stillbirth was 1.4% in later pregnancies.

Patients with molar pregnancies and GTN should be reassured that they can in general expect a normal future reproductive outcome.
