Mortality due to hepatocellular carcinoma associated with hepatitis B and C viruses in the state of São Paulo, Brazil

Mortalidade por carcinoma hepatocelular associado às hepatites virais B e C no estado de São Paulo, Brasil

ABSTRACT:

Objective:

This study aimed to describe and analyze the temporal and spatial distribution of deaths due to hepatocellular carcinoma (HCC) associated with hepatitis B (HBV) and C viruses (HCV) in the state of São Paulo.

Methods:

This is an ecological study of HCC deaths associated with HBV and HCV in the state of São Paulo, from 2009 to 2017, with data from the Mortality Information System (SIM). The temporal trend was analyzed by linear regression with Prais–Winsten estimation. Deaths were described according to sociodemographic characteristics by means of absolute and relative frequencies and were spatially distributed according to the regional health department.

Results:

It is found that 26.3% of deaths due to HCC were associated with HBV or HCV. A higher proportion of deaths due to HCC associated with HCV was observed (22.2%) when compared to HBV (3.9%). The mortality rate due to HCC associated with HBV showed a downward trend, and the mortality rate due to HCC associated with HCV showed a steady trend. Deaths of males, white individuals, those who aged from 50 to 59 years, and those who had 8–11 years of schooling predominated. Spatial analysis revealed a heterogeneous distribution of deaths in the state of São Paulo.

Conclusions:

The downward trend in mortality rates due to HCC associated with HBV shows an important advance in the disease control. However, the mortality rate due to HCC associated with HCV has remained stable throughout the study period. The spatial distribution of deaths may contribute to raise hypotheses for deeper knowledge of these diseases in the regions.
