Abstract
BACKGROUND AND AIMS
The most common cause of hepatocellular carcinoma (HCC), which has a high death rate, is hepatitis B virus (HBV) infection. This study aimed to examine immunoexpression of CB1 receptors in the livers of patients with HBV-related HCC in comparison with HCC and chronic HBV as well as healthy people. Patients and methods Participants in this case-controlled study were patients with only HBV (HBV; 40), only HCC (HCC; 41), and HBV-related HCC (HBV + HCC; 40) and a healthy control group (C; 30). Tissue expression of CB1 at the protein level was studied using immunohistochemical methods.
RESULTS
All groups were significantly different in terms of expression of CB1 protein (P < 0.001). The expression levels of CB1 in the liver tissue of the HBV and C groups were not significantly different (P = 0.072). The expression levels of CB1 in the liver tissue of the HBV-related HCC and HCC groups had a statistically significant increase compared to the C and HBV groups (P < 0.001). Also, the CB1 expression levels in the liver tissues of HBV-related HCC and HCC groups were significantly different (P = 0.008). The sensitivity and specificity of immunohistochemistry tests in the diagnosis of HCC using CB1 were 63.4 and 91.2, respectively. Positive and negative predictive values were 90.0 % and 65.1 %, respectively. There was no relationship between the expression of CB1and other clinicopathological variables (P < 0.05).
CONCLUSION
The present findings revealed a tumor promoting function of the CB1 receptor in HCC. CB1 is also a pathological valuable factor for identifying the pathway of inflammation during infection.
