Gestational trophoblastic disease within an elective abortion population

Area of Science:

• Obstetrics and Gynecology
• Reproductive Endocrinology
• Pathology

Background:

• Gestational trophoblastic disease (GTD), primarily hydatidiform mole, is uncommon in the United States.
• Reported incidence of hydatidiform mole ranges from 1 in 1,200 to 1 in 2,000 pregnancies.

Purpose of the Study:

• To report the occurrence of eight cases of hydatidiform mole in a specific patient cohort.
• To investigate potential factors contributing to a higher observed frequency of hydatidiform mole.

Main Methods:

• Retrospective review of 4,829 patients undergoing elective first-trimester abortion.
• Analysis of cases presenting with hydatidiform mole.
• Discussion of potential etiological factors.

Main Results:

• Eight cases of hydatidiform mole were identified among 4,829 patients.
• This represents an incidence of approximately 1 in 600 pregnancies within this cohort.
• Factors potentially influencing this elevated frequency are discussed.

Conclusions:

• The observed incidence of hydatidiform mole in this study was higher than previously reported.
• Accurate diagnosis necessitates thorough gross examination of suction curettage tissue.
• Histologic evaluation is essential for confirming diagnosis in ambiguous cases.
