Insights
Hepatitis C virus (HCV) genotype 2 is associated with improved survival in patients with liver cancer (HCC). This finding suggests genotype may influence treatment outcomes for HCV-related HCC.
Area of Science:
- Hepatology
- Virology
- Oncology
Background:
- Hepatocellular carcinoma (HCC) is a major complication of chronic hepatitis C virus (HCV) infection.
- The impact of specific HCV genotypes on HCC patient survival remains unclear.
- This study investigates the relationship between HCV genotype and survival in HCC patients.
Purpose of the Study:
- To determine if hepatitis C virus (HCV) genotype influences survival rates in patients diagnosed with hepatocellular carcinoma (HCC).
- To analyze survival differences based on HCV genotypes (1, 2, and 3) in a Korean cohort.
- To identify independent prognostic factors for mortality in HCV-related HCC.
Main Methods:
- Retrospective cohort study of 180 patients with HCV-related HCC from 2005-2016.
- Propensity score matching was employed to minimize bias between genotype 2 and non-genotype 2 groups.
- Multivariate Cox regression analysis was used to assess risk factors for death.
Main Results:
- Patients with HCV genotype 2 demonstrated significantly longer median overall survival (31.7 months) compared to genotype 1 (28.7 months) and genotype 3 (15.0 months).
- Genotype 2 was associated with improved decompensation-free survival.
- No significant difference in recurrence-free survival was observed for patients undergoing curative treatment.
Conclusions:
- Hepatitis C virus (HCV) genotype 2 is linked to better survival outcomes in patients with HCV-related hepatocellular carcinoma (HCC).
- Non-genotype 2 is an independent risk factor for mortality in this patient population.
Background:
There is currently no evidence that hepatitis C virus (HCV) genotype affects survival in patients with hepatocellular carcinoma (HCC). This study aimed to investigate whether the HCV genotype affected the survival rate of patients with HCV-related HCC.
Methods:
We performed a retrospective cohort study using the data of patients with HCV-related HCC evaluated at two centers in Korea between January 2005 and December 2016. Propensity score matching between genotype 2 patients and non-genotype 2 patients was performed to reduce bias.
Results:
A total of 180 patients were enrolled. Of these, 86, 78, and 16 had genotype 1, genotype 2, and genotype 3 HCV-related HCC, respectively. The median age was 66.0 years, and the median overall survival was 28.6 months. In the entire cohort, patients with genotype 2 had a longer median overall survival (31.7 months) than patients with genotype 1 (28.7 months; P = 0.004) or genotype 3 (15.0 months; P = 0.003). In the propensity score-matched cohort, genotype 2 patients also showed a better survival rate than non-genotype 2 patients (P = 0.007). Genotype 2 patients also had a longer median decompensation-free survival than non-genotype 2 patients (P = 0.001). However, there was no significant difference in recurrence-free survival between genotype 2 and non-genotype 2 patients who underwent curative treatment (P = 0.077). In multivariate Cox regression analysis, non-genotype 2 (hazard ratio, 2.19; 95% confidence interval, 1.29-3.71) remained an independent risk factor for death.
Conclusion:
Among patients with HCV-related HCC, those with genotype 2 have better survival.
