[Primary liver cell carcinoma among the population of Białystok in 1975-1988 in relation to hepatitis B virus infection].

In presented study, retrospective epidemiological analysis was performed in 84 patients dead due primary hepatocellular carcinoma, selected from among 17,973 persons dead in Białystok hospitals from 1975 till 1988. In the part from among these patients was estimated prevalence of serological markers of Hepatitis B virus infection, as a potential oncogenic factor. Analysis of this carcinoma diagnosis frequency in particular years showed rising tendency: from 1975 till 1979 number of PHC diagnosis was from 0 to 5 a year, whereas in 1988 it was 13. Percentage of necropsy diagnosed PHC was similar and increased to over 1% of all necropsies in 1988. Mean age of patients dead due PHC was 65, and 71.4% were men. Serological markers of HBV infection were observed in 50% and HBsAg in 34.6% from among PHC-dead patients. These percentage values were significantly higher, than observed in control group of Białystok population, which indicate possibility of association between HBV infection and PHC development.
