Current trends of the changes of the etiological structure and clinical and laboratory characteristics of hepatocellular carcinoma

Abstract

The etiological structure of chronic viral hepatitides with the outcome in hepatocellular carcinoma (HCC) was studied among deceased patients for the periods of 1986-1998 and 2002-2012 in total and in comparison. HCC developed as the outcome of CHB in 45.0% of patients, CHC - in 20.7 % , CHB+C - 18,6%, CVHN- in 12.9%, CHB + D - 1.4%, CHB+C+D - also in 1.4% of patients. When comparing the data for 1986-1998 (13 years), and 2002-2012 (11 years) there was noticed an increase in the number of deaths from HCC (2-fold), there was significantly increased the incidence of HCC, associated with CHC (from 2.0% to 30.8 %), nonverified chronic hepatitis as a cause of HCC occurred 6.5 times less often (28.6 % - 4.4%), the number of cases of HCC, caused by CHB, became lower (49.0 % - 42.9 %), CHB+C - almost unchanged (20.4% - 17.6 % ). A presumptive middle time of the development of HCC since infection with hepatitis viruses is 27,6 ± 9,8 years. In assessing the cofactors ofprogression of HCC there was found that alcohol abuse occurred in 38.5 % ofpatients, diabetes - in 18,7%, HIV- infection -in 3.3%.
