Background: The aim of this study was to evaluate the effect of chronic hepatitis B infection on the risk of synchronous colorectal liver metastasis (synCRLM). Methods: A total of 4033 consecutive patients with newly diagnosed colorectal cancer (CRC) with hepatitis B testing were enrolled. The prevalence of synCRLM was compared between hepatitis B surface antigen (HBsAg)-positive and -negative patients; significant predictors for synCRLM were analyzed by logistic regression analysis; Fibrosis-4 Index for Liver Fibrosis (FIB-4), aspartate aminotransferase-to-platelet ratio index (APRI), and hepatitis B e antigen (HBeAg) status were compared between patients with or without synCRLM. Results: The prevalence of synCRLM was significantly higher in the HBsAg+ patients than that in the HBsAg- patients (15.57% vs 8.60%; P < .001, χ2 test). A logistic regression analysis indicated that HBsAg+ showed the highest hazard ratio (2.317 [95% confidence interval, 1.406-3.820]) for synCRLM. Both FIB-4 and APRI were significantly higher in those with HBsAg positivity but no synCRLM compared to those with HBsAg positivity and synCRLM (FIB-4: 1.23 [0.92-1.88] vs 1.09 [0.74-1.51], P = .045; APRI: 0.23 [0.227-0.387] vs 0.18 [0.171-0.309], P = .023, Mann-Whitney test; all shown as median [25th-75th percentile]); HBeAg positivity was detected in 26.32% of those with positive HBsAg and synCRLM compared to 18.45% of those with positive HBsAg but no synCRLM; the difference was not statistically signifi...
