“…In Australia it is most commonly associated with cirrhosis in chronic alcoholics, although in other Caucasian populations the incidence of hepatoma is higher in cirrhosis of the macronodular or postnecrotic type (MacDonald, 1957;Kew et al, 1791). In East Africans (Maynard et al, 1970;Bagshawe et al, 1971) and West Africans (Morrow et al, 1971) viral hepatitis is common, and is strongly associated with H.A.A. In these populations postnecrotic cirrhosis and of primary hepatoma are also much commoner than in Caucasians.…”
