Summary

Partial hydatidiform mole (PHM) patients rarely require chemotherapy for malignant sequelae. Discontinuing human chorionic gonadotrophin (hCG) monitoring after normal levels are achieved is safe for PHM patients.

Area of Science:

  • Gynecology
  • Reproductive Endocrinology
  • Oncology

Background:

  • Partial hydatidiform mole (PHM) is a gestational trophoblastic disease.
  • Monitoring human chorionic gonadotrophin (hCG) levels is crucial for detecting persistent trophoblast disease.
  • Optimal follow-up protocols for PHM require further investigation.

Purpose of the Study:

  • To determine the risk of persistent trophoblast disease after partial molar pregnancy.
  • To review the current follow-up protocol for patients with partial hydatidiform molar pregnancy (PHM).

Main Methods:

  • Retrospective analysis of 344 PHM cases from January 1992 to January 2001.
  • Review of demographic factors, gestation length, hCG levels, and follow-up compliance.
  • Analysis of hCG regression assays for 235 patients.

Main Results:

  • 1.7% of PHM patients required chemotherapy for malignant sequelae.
  • No patient with normal hCG levels experienced relapse after achieving remission.
  • 152 (64.7%) patients normalized hCG within 2 months post-evacuation; all within 32 weeks.
  • Only 25.6% of patients completed the recommended follow-up program.

Conclusions:

  • Malignant sequelae requiring treatment occur in a small percentage of PHM cases.
  • Discontinuation of hCG monitoring after normalization is safe and supported by data.
  • Current follow-up protocols may be adjusted based on achieving normal hCG levels.
