Persistent hepatitis B virus infection and hepatoma in the Gambia, West Africa : a case-control study of 140 adults and their 603 family contacts.
To determine the incidence of persistent hepatitis B virus infection and its etiologic role as a cause of hepatoma, the authors carried out a case-control investigation of 70 persons with hepatoma, 70 controls, and their families in 1981-1982 in The Gambia, West Africa.
The risk of developing hepatoma after the age of 39 years was 1.4% in men and 0.3% in women.
Hepatoma occurred more than twice as frequently among persons who had four or more older siblings as among persons who had less than two older siblings.
