title: The occurrence of trophoblastic disease in Western Samoa.
abstract: In order to study the occurrence of hydatidiform mole and choriocarcinoma in the island of Western Samoa in the South Pacific, a delivery based study was carried out. All deliveries, both livebirths and stillbirths at the main referral centre (National Hospital), all livebirths at the district hospitals/health centres and all live home deliveries 1980-87 were included. Thirty-two hydatidiform mole cases were recorded on pathological and clinical grounds. No case of choriocarcinoma was encountered. The incidence rate of hydatidiform mole was estimated to be 0.90 per 1000 deliveries, the estimated frequency rate being 1:1109 deliveries. The mean age of cases was 31 years, ranging from 19 to 48. It is suggested that the incidence of trophoblastic disease is not significant in Western Samoa in terms of geographical variations. The importance of methodology in estimating the incidence was also discussed.
