Subsequent pregnancy outcomes after complete and partial molar pregnancy, recurrent molar pregnancy, and gestational trophoblastic neoplasia: an update from the New England Trophoblastic Disease Center

J Reprod Med. May-Jun 2014;59(5-6):188-94.


Objective: To review and update the subsequent reproductive outcomes in patients with complete, partial, and recurrent hydatidiform moles, as well as gestational trophoblastic neoplasia (GTN) at the New England Trophoblastic Disease Center.

Study design: Patients with complete and partial hydatidiform mole, recurrent hydatidiform mole, and GTN were identified from the Donald P. Goldstein, M.D., Trophoblastic Tumor Registry. Questionnaires regarding subsequent pregnancies were mailed to patients with current mailing addresses available. Additional patient data was obtained from electronic medical records.

Results: A total of 2,432 subsequent pregnancies have been reported since 1965. Of those, 1,388 pregnancies were after complete mole, 357 after partial mole, and 667 after GTN. The subsequent reproductive outcomes in patients with complete and partial molar pregnancies and persistent GTN remain similar to those in the general population. However, approximately 1.7% of patients with a prior molar pregnancy had a molar pregnancy in a later gestation. Furthermore, after successful chemotherapy for GTN the incidence of stillbirth was slightly increased to 1.3% in later pregnancies.

Conclusion: Patients with molar pregnancies and GTN should expect similar reproductive outcomes as compared to the general population. However, patients receiving chemotherapy for GTN have a slightly increased risk stillbirth in subsequent pregnancies.
