Abstract

Objective: Partial hydatidiform moles infrequently progress to gestational trophoblastic neoplasia. The purpose of this study was to determine the optimal duration of human chorionic gonadotropin surveillance. Study design: We retrospectively reviewed the clinical follow-up of all women who were diagnosed with partial hydatidiform mole at our institution from 1983 to 2003. Results: One hundred sixty-three patients were identified with a median age of 23 years (range, 14-42 years). Seventy-four patients (45%) attained undetectable levels of human chorionic gonadotropin; none of the patients had gestational trophoblastic neoplasia. Forty patients completed the 6 months of recommended follow-up; 6 patients conceived during surveillance, and 28 patients did not return for any further office visits 1 to 5 months after achieving remission. Eighty-three patients (51%) were lost to follow-up before normalization of human chorionic gonadotropin. Six women (4%) had stage I gestational trophoblastic neoplasia during surveillance. Conclusion: Our results support the suggestion that a single undetectable human chorionic gonadotropin level after evacuation is sufficient follow-up to ensure remission in patients with partial hydatidiform moles.
