The Registry for Diseases of Trophoblast: The First Year

Radiological Changes in the Chest in Malignant Trophoblastic Disease

“…Malignant trophoblastic neoplasia appears to be more common in Africa and the Far East than in the West. Park (1962) reported only one death from choriocarcinoma in 70,000 live births in Great Britain and Northern Ireland, while the incidence in the United States has been reported to be from 1 in 13,850 to 1 in 40,000 deliveries (Teoh, Dawood and Ratnam, 1972). These figures compare with a tumour incidence of 1 in 1,33 1 hospital deliveries at the University Hospital, Hong Kong (Chan, 1962) ; 1 in 1,382 pregnancies in a hospital practice in the Philippines (Acosta-Sison, 1962); and 1 in 4,298 deliveries in Singapore (Teoh et al, 1972).…”
