title: Epidemiologic study of gestational trophoblastic diseases in Saudi Arabia.
abstract: The role of cultural and socioeconomic diversities (that is, marriage, conceptions at the extremes of reproductive life, consanguinity, economic affluence and such) were analyzed for significance in the epidemiologic study of gestational trophoblastic disease (GTD) in Saudi Arabia. For the study period, the incidence of hydatidiform mole remained unchanged at a mean of one in 448 pregnancies and one in 6,130 for its malignant counterpart. In the instance of molar pregnancies, the youngest (less than 20 years of age) and the oldest (more than 40 years of age) had significantly higher than expected incidence; in contrast, in malignant GTD, the trend was for a higher than expected frequency for the older age group only (more than 40 years of age). Consanguinity showed no significant epidemiologic role.
