Risk of recurrence in chronic hepatitis B patients developing hepatocellular carcinoma with antiviral secondary prevention failure

Diabetes Mellitus Negatively Impacts Outcomes of HBV-Related Hepatocellular Carcinoma Following Thermal Ablation

Purpose

Diabetes mellitus (DM) negatively impacts chronic hepatitis B patients, but its role in those with HBV-related hepatocellular carcinoma (HCC) undergoing ablation remains unclear. This study aims to evaluate the influence of DM on recurrence patterns and overall survival (OS) among patients with HBV-related HCC undergoing ablation.

Patients and Methods

We retrospectively enrolled 372 patients receiving thermal ablation for HBV-related HCC, including 96 (25.8%) patients with DM. Factors associated with local tumor progression (LTP), distant recurrence, and OS were analyzed. The prognostic value of DM in IMbrave050-defined high-risk population was validated.

Results

DM did not correlate with LTP, whereas patients with DM had significantly higher risk of distant recurrence (median time to recurrence 23.7 versus 46.2 months, p=0.032), poorer OS (median OS 75.6 versus 106 months, p=0.011), and poorer post-recurrence survival (70.7 versus 106 months, p=0.009). In multivariate analysis, DM (hazard ratio (HR)=1.466, p=0.012), FIB-4 score, multiple tumors, and AFP level were independent predictors of distant recurrence, while DM (HR=1.424, p=0.028), ALBI score, tumor size, AFP and creatinine levels were significantly associated with OS. A DM-based risk score effectively discriminated the risk of distant recurrence. The IMbrave050 criteria could stratify the risk of LTP but not distant recurrence. DM status further discriminated the risk of distant recurrence and mortality in the IMbrave050-defined high-risk population.

Conclusion

Patients with DM had an increased risk of distant recurrence and mortality after thermal ablation for HBV-related HCC, highlighting the importance of increasing awareness of DM and implementing rigorous post-ablation monitoring for diabetic HCC patients.

Recurrence of hepatocellular carcinoma in noncirrhotic patients with nonalcoholic fatty liver disease versus hepatitis B infection

BACKGROUND AND AIMS

This study aimed to compare the long-term cumulative recurrence rates of hepatocellular carcinoma (HCC) and prognosis after curative resection for HCC in noncirrhotic patients with nonalcoholic fatty liver disease (NAFLD) versus hepatitis B virus (HBV) infection.

METHODS

We retrospectively analyzed the data of 791 patients without recurrence within 1 year after curative resection for HCC from January 2005 to December 2015. Of these, 63 and 728 were NAFLD and HBV patients without cirrhosis, respectively.

RESULTS

Recurrence of HCC was observed in 6 (9.5%) and 210 (28.8%) patients in the NAFLD and HBV groups, respectively, during median follow-ups of 69.9 and 85.2 months. Cumulative recurrence rates in the NAFLD group at 2, 4, 6, 8 and 10 years (3.6, 9.4, 12.4, 12.4 and 12.4%, respectively) were significantly lower than in the HBV group (1.7, 16.9, 27.2, 37.1 and 44.4%, respectively) ( P  = 0.008). Cumulative overall survival (OS) rates in the NAFLD group at 2, 4, 6, 8 and 10 years (98.2, 96.0, 84.0, 84.0 and 84.0 %, respectively) were significantly lower than in the HBV group (99.3, 98.4, 97.3, 95.7 and 93.6%, respectively) ( P  = 0.003). HBV infection, with or without fatty liver compared to NAFLD, were significant predictors for the recurrence of HCC ( P  < 0.05 for all) and OS ( P  < 0.05 for all), respectively.

CONCLUSIONS

Noncirrhotic NAFLD patients showed lower recurrence rates of HCC but poorer survival outcomes than noncirrhotic HBV patients with or without fatty liver. The recurrence risk of HCC remains even in noncirrhotic NAFLD patients.

Application and Impact of Antiviral Therapy for Patients with HBV-Related Hepatocellular Carcinoma Receiving Sorafenib and Lenvatinib Treatment

Overall survival (OS) in patients with advanced hepatocellular carcinoma (HCC) has improved in the era of multi-line sequential therapy. The application of antiviral therapy and its impact on survival for patients with HBV-related HCC needs to be reassessed. The aim of this study was to evaluate the application and impact of antiviral therapy on survival for patients with HBV-related HCC receiving tyrosine kinase inhibitor (TKI) therapy. Patients with advanced HBV-related HCC treated with sorafenib or lenvatinib as first-line therapy with (n = 377) and without (n = 182) nucleos(t)ide analogue (NUC) therapy were retrospectively enrolled. Prognostic factors of OS were evaluated. Secular trends in the increased application of NUC therapy and improved survival were observed in the last decade. The HBV reactivation rate in patients without NUC therapy was 6.6%. By multivariate analysis, baseline low HBV viral load, achieving undetectable HBV DNA after TKI therapy, and ability to receive second-line therapy were found to be independent predictors of OS. In subgroup patients with NUC therapy, starting NUC before TKI was associated with a better OS. In conclusion, the application of antiviral therapy for patients with HBV-related HCC receiving TKI therapy has increased over time. Achieving complete virological suppression may contribute to a better OS in patients with advanced HBV-related HCC.

Comparable benefits of HCV eradication by direct acting antivirals and interferon-based therapy in patients with hepatocellular carcinoma undergoing surgical resection

Whether direct-acting antivirals (DAA) provide comparable survival benefit with interferon (IFN)-based therapy remains unclear. The aim of this study was to compare the outcomes after achieving SVR by IFN-based and DAA therapy after resection of HCV-related hepatocellular carcinoma (HCC). Consecutive 285 patients receiving curative resection for HCV-related HCC were retrospectively enrolled, including 103 (36.1%) and 69 (24.2%) patients with IFN-based and DAA therapy, respectively. Factors associated with recurrence, overall survival (OS) and hepatic decompensation-free survival were evaluated. The SVR rate of DAA was 95.7% in HCC patients. During a median follow-up period of 49.6 months, 102 (35.8%) patients died and 63 (24%) developed hepatic decompensation. By multivariate analysis, SVR by DAA or IFN-based therapy was not associated with early or late HCC recurrence. Achieving SVR (by IFN-based therapy: HR=0.321, P<0.001; by DAA: HR=0.396, P=0.011), BCLC stage B-C (HR=1.914, P=0.024), FIB-4 score >3.25 (HR=1.664, P=0.016) and microvascular invasion (HR=1.603, P=0.048) were independent predictors of OS. Achieving SVR (by IFN-based therapy: HR=0.295, P<0.001; by DAA: HR=0.193, P=0.002), BCLC stage B-C (HR=2.975, P=0.001), GGT >70 U/L (HR=1.931, P=0.015) and cirrhosis (HR=2.035, P=0.007) were independent predictors of decompensation-free survival. The benefit of achieving SVR was consistently observed in cirrhotic and non-cirrhotic patients, and in patients with and without HCC recurrence. In conclusion, achieving SVR by either DAA or IFN-based therapy provide comparable and significant reduction of mortality and hepatic decompensation after surgical resection of HCV-related HCC. DAA therapy should be prescribed for all HCC patients after curative surgical resection.

Predictors of long-term recurrence and survival after resection of HBV-related hepatocellular carcinoma: the role of HBsAg

The recurrence rate remains high even under nucleos(t)ide analogues (NUCs) therapy in patients with hepatitis B virus (HBV)-related hepatocellular carcinoma (HCC) after resection. The aim of this study is to evaluate the prognostic role of HBsAg in patients undergoing surgical resection for HBV-related HCC in NUCs era. Consecutive 522 patients undergoing surgical resection for HBV-related HCC were retrospectively enrolled. Factors associated with early (within 2 years), late (year 2 to 5), very late (beyond 5 years) recurrence and early or late mortality (within or beyond 5 years) were evaluated. During a median follow-up period of 59 months, 308 (59%), and 146 (28%) patients developed recurrence and mortality, respectively. HBsAg level did not correlate with early recurrence and mortality. By multivariate analyses, HBsAg >200 IU/mL (hazard ratio (HR)=1.778, P=0.037) and presence of cirrhosis (HR=2.157, P=0.001) were independent predictors of late recurrence, while HBsAg >50 IU/mL (HR=4.658, P=0.038), body mass index >25 kg/m² (HR=2.720, P=0.013) and significant hepatic fibrosis (HR=2.509, P=0.039) were independent predictors of very late recurrence. HBsAg >50 IU/mL (HR=11.427, P=0.017), age >60 years (HR=2.688, P=0.006), albumin ≤3.5 g/dL (HR=4.739, P<0.001) and presence of cirrhosis (HR=2.781, P=0.006) were independent predictors of late mortality beyond 5 years. Combining these factors could well predict patients with minimal risk of long-term recurrence and mortality. In conclusion, tumor factors, liver function surrogate markers, metabolic factors and serum HBsAg levels play distinct roles in recurrence and survival at different time intervals after surgical resection for HBV-related HCC. Pre-operative HBsAg level is an important predictor of long-term recurrence and survival in patients with HBV-related HCC undergoing surgical resection.

Early and late recurrence of surgically resected hepatitis B virus-related hepatocellular carcinoma on nucleos(t)ide analogues therapy

BACKGROUND/PURPOSE

Hepatocellular carcinoma (HCC) is a highly recurrent tumor. Antiviral therapy with nucleos(t)ide analogues (NUCs) may reduce the risk of recurrence in hepatitis B virus (HBV)-related HCC. The risk factors associated with recurrence in HCC patients after surgical resection and with NUCs treatment should be delineated.

METHODS

Consecutive 339 HBV-related HCC patients receiving surgical resection of HCC with NUCs therapy (including 256 entecavir, 36 tenofovir, and 18 lamivudine) after the surgery were retrospectively reviewed. Factors related to the recurrence-free survival (RFS) and overall survival (OS) were evaluated.

RESULTS

After a median of 48.5 months of follow-up, 183 (54%) patients developed HCC recurrence, with the 5-year RFS of 42.8% and OS of 79%. Male gender (HR = 1.736, p = 0.037), baseline HBsAg level >200 IU/ml (HR = 1.748, p = 0.008), platelet count ≦100 (10⁹/L) (HR = 1.592, p = 0.023), presence of microscopic vascular invasion (MVI) (HR = 1.499, p = 0.026), safety cut margin of ≦0.5 cm (HR = 1.507, p = 0.013), and Ishak fibrosis score 5-6 (HR = 1.579, p = 0.009) were independent factors associated with RFS in multivariate analysis. While tumor burden, platelet count, MVI, and safety cut margin were factors associated with early recurrence; baseline HBsAg level, and platelet count were independent factors associated with late recurrence. Ishak fibrosis score 5-6, poor differentiation, MVI, diabetes mellitus were factors associated with OS in multivariate analysis.

CONCLUSION

For HBV-HCC patients on NUCs treatment, tumor factors are associated with early recurrence, while HBsAg level and thrombocytopenia determines late recurrence. For patient with a high baseline HBsAg level, warning of higher risk of recurrence is required even under NUCs treatment.
