Summary

Patients with complete hydatidiform mole (CHM) achieving normal human chorionic gonadotrophin (hCG) levels rarely develop persistent disease. Discontinuing monitoring after normal hCG levels within two months is safe for CHM patients.

Area of Science:

  • Gynecology
  • Oncology
  • Reproductive Endocrinology

Background:

  • Complete hydatidiform mole (CHM) is a gestational trophoblastic neoplasm.
  • Monitoring human chorionic gonadotrophin (hCG) levels is crucial after molar evacuation.
  • Persistent or recurrent disease necessitates timely intervention.

Purpose of the Study:

  • To evaluate the incidence of persistent or recurrent gestational trophoblast disease in CHM patients with spontaneous normalization of hCG levels.
  • To identify safe monitoring protocols for CHM survivors.

Main Methods:

  • Retrospective review of 414 CHM cases from the Hydatidiform Mole Registry of Victoria.
  • Analysis of maternal age, gestational age, gravidity, parity, and chemotherapy requirements.
  • Correlation of hCG normalization timelines with disease persistence.

Main Results:

  • 55 out of 414 (13.3%) CHM patients required chemotherapy for persistent trophoblastic disease.
  • No patients who achieved spontaneous normalization of hCG levels subsequently developed persistent molar disease.
  • This suggests a low risk of recurrence once hCG levels normalize.

Conclusions:

  • Weekly hCG monitoring is recommended until normalization.
  • Discontinuation of monitoring may be safe for CHM patients achieving normal hCG levels within 2 months post-evacuation.
  • Continued monthly monitoring for 1 year is advised for patients not normalizing by 2 months to ensure sustained remission.
