Effects of transarterial chemoembolization combined with antiviral therapy on HBV reactivation and liver function in HBV-related hepatocellular carcinoma patients with HBV-DNA negative

TACE versus TACE + entecavir versus TACE + tenofovir in the treatment of HBV associated hepatocellular carcinoma

BACKGROUND

At present, there are a variety of antiviral drugs for HBV in clinical practice, but there is no standard scheme for transcatheter arterial chemoembolization(TACE) combined with antiviral drugs. The aim of this study was to investigate whether TACE must be combined with antiviral therapy in patients of HBV-related hepatocellular carcinoma(HCC). Meanwhile, the efficacy and safety of TACE combined with entecavir and TACE combined with tenofovir in the treatment of HBV-related HCC were compared.

METHOD

This study included 536 patients with HBV-related HCC who underwent TACE in Union Hospital from March 2017 to March 2020, and they met the criteria. They were divided into three groups: control group (N = 212): TACE alone; Entecavir group (N = 220): TACE combined with entecavir; and Tenofovir group (N = 228): TACE combined with tenofovir. We conducted a retrospective study to analyze the efficacy and safety of the three groups of patients.

RESULTS

Objective response rate(ORR): 29.2% in control group, 54.1% in entecavir group, and 63.2% in tenofovir group (P < 0.05). Disease control rate(DCR): 63.7% in control group, 80.9% in entecavir group, and 88.1% in tenofovir group (P < 0.05). Median overall survival(mOS): control group, 12.2 months; entecavir group, 17.3 months; tenofovir group, 22.5 months (p < 0.05). Median progression-free survival (mPFS): control group, 9.3 months; entecavir group, 15.5 months; tenofovir group, 16.6 months (p < 0.05). At 6 months, there was an increase in creatinine(Cr) and a decrease in glomeruar filtration rate(GFR) in tenofovir group, which were statistically different from control and entecavir groups (p < 0.05).

CONCLUSION

TACE combined with entecavir and TACE combined with tenofovir had higher ORR and DCR, longer OS and PFS than TACE alone. The OS of TACE combined with tenofovir was higher than that of TACE combined with entecavir. TACE combined with tenofovir is a safe strategy, but we cannot completely ignore the impact of tenofovir on renal function.

Efficacy of nucleos(t)ide analogues(NAs) in preventing virus reactivation in oncology patients with HBV infection after chemotherapy or surgery: A network meta-analysis

Objective

In this study, we aimed to perform a network meta-analysis to compare the effectiveness of NAs in decreasing the reactivation of HBV, reducing chemotherapy disruption, and improving survival in oncology patients.

Methods

Relevant randomized controlled trials (RCT) evaluating the impact of NAs in HBV infected-related oncology patients were retrieved from electronic databases. The outcome indicators included reactivation rate, survival rate of 1 to 3 years after treatment, and chemotherapy disruption rate. The studies were evaluated for bias using the RCT risk of bias assessment tool recommended in the Cochrane Handbook. The risk ratio (RR) was used to compare the outcome indicators for the anti-viral treatment, and the surface under the cumulative ranking curves (SUCRA) was used to identify the optimal therapeutic regime.

Results

A total of 67 trials containing 5722 patients were included in this study. Regarding the reduction of reactivation rate, entecavir, lamivudine, adefovir alone were less effective than the combination of lamivudine and entecavir (94.9%), with RR values ranging from 3.16 to 3.73. However, based on SUCRA, the efficacy of telbivudine (80.3%) and the combination of lamivudine and adefovir dipivoxil (58.8%) were also acceptable. Entecavir (RR values ranging from 1.25 to 1.50) and lamivudine (RR values ranging from 1.27 to 1.35) can prolong the survival rate of patients at 1-3 years, and were better than adefovir dipivoxil in the comparison of 1-year survival rate. The RR values were 1.18 and 1.19, respectively. And entecavir 's ranking in SUCRA was more stable. Entecavir, lamivudine, and tenofovir all reduced chemotherapy interruption rates compared with no antiviral therapy, especially for tenofovir.

Conclusions

Current evidence shows that lamivudine combined with entecavir, telbivudine, and lamivudine combined with adefovir dipivoxil were the most effective in preventing virus reactivation in HBV infected-related cancer patients treated with chemotherapy. Entecavir had the most stable effect on survival, while tenofovir had the best impact on reducing the chemotherapy disruption rate. Due to limited quality and quantity of the included studies, more high-quality studies are required to verify the above conclusions.

Peripartum management of tuberous sclerosis complex complicated by massive angiomyolipomas

Tuberous sclerosis complex is a genetic disease that can affect multiple organs, commonly the renal, central nervous, cardiac and respiratory systems. Here, we present the peripartum management of a woman with a new diagnosis of tuberous sclerosis complex associated with massive renal angiomyolipomas. There was significant risk of catastrophic haemorrhage from the angiomyolipomas during pregnancy. This created a challenging scenario for the anaesthetists, obstetricians, urologists and interventional radiologists involved in their care, necessitating collaborative working, numerous investigations and honest patient-centred discussions. Evidence for the management of tuberous sclerosis and angiomyolipomas in pregnancy does not appear to have been previously reported. After much consideration, arterial embolisation of the most vascular area of the angiomyolipoma was completed at 28 weeks gestation under remifentanil sedation. An elective caesarean section under combined spinal epidural anaesthesia was completed at 37 + 3 weeks gestation. Central nervous system involvement must always be considered; benign tumours within the brain and spinal cord may contraindicate neuraxial techniques. Early multidisciplinary involvement is essential due to the diverse and complex nature of tuberous sclerosis. Individuals differ in their presentation and disease severity; therefore, they must be assessed on an individual basis with management tailored accordingly.

Transcatheter arterial chemoembolization followed by surgical resection for hepatocellular carcinoma: a focus on its controversies and screening of patients most likely to benefit

Surgical resection (SR) is recommended as a radical procedure in the treatment of hepatocellular carcinoma (HCC). However, postoperative recurrence negatively affects the long-term efficacy of SR, and preoperative adjuvant therapy has therefore become a research hotspot. Some clinicians adopt transcatheter arterial chemoembolization (TACE) as a preoperative adjuvant therapy in patients undergoing SR to increase the resection rate, reduce tumor recurrence, and improve the prognosis. However, the findings of the most relevant studies remain controversial. Some studies have confirmed that preoperative TACE cannot improve the long-term survival rate of patients with HCC and might even negatively affect the resection rate. Which factors influence the efficacy of preoperative TACE combined with SR is a topic worthy of investigation. In this review, existing clinical studies were analyzed with a particular focus on several topics: screening of the subgroups of patients most likely to benefit from preoperative TACE, exploration of the optimal treatment regimen of preoperative TACE, and determination of the extent of tumor necrosis as the deciding prognostic factor.

Advances in treatment and prevention of hepatitis B

Chronic hepatitis B (CHB) continues to contribute to worldwide morbidity and mortality significantly. Scientists, clinicians, pharmaceutical companies, and health organizations have dedicated substantial Intellectual and monetary resources to finding a cure, increasing immunization rates, and reducing the global burden of CHB. National and international health-related organizations including the center for disease control, the national institute of health, the American Association for the study of liver disease (AASLD), The European association for the study of the Liver (EASL), The Asia Pacific association for the study of the Liver (APASL) and the world health organization release periodic recommendations for disease prevention and treatment. Our review of the most recent guidelines by EASL, AASLD, APASL, and Taiwan Association for the Study of the Liver revealed that an overwhelming majority of cited studies were published before 2018. We reviewed Hepatitis B-related literature published 2018 onwards to identify recent developments and current barriers that will likely direct future efforts towards eradicating hepatitis B. The breakthrough in our understanding of the hepatitis B virus life cycle and resulting drug development is encouraging with significant room for further progress. Data from high-risk populations, most vulnerable to the devastating effects of hepatitis B infection and reactivation remain sparse. Utilization of systems approach, optimization of experimental models, identification and validation of next-generation biomarkers, and precise modulation of the human immune response will be critical for future innovation. Within the foreseeable future, new treatments will likely complement conventional therapies rather than replace them. Most Importantly, pragmatic management of CHB related population health challenges must be prioritized to produce real-world results.

Effect of antiviral therapy in patients with low HBV DNA level on transarterial chemoembolization for hepatocellular carcinoma

Antiviral therapy improves survival in patients with hepatitis B virus (HBV)-induced hepatocellular carcinoma (HCC). However, the effect of antiviral therapy in patients with low-level viremia HBV-HCC receiving non-curative therapy remains unclear. We aimed to evaluate the role of antiviral therapy in patients with low-level viremia and treated with transarterial chemoembolization (TACE). This retrospective study evaluated 206 patients with HBV-HCC who underwent TACE as an initial treatment. Of those, 135 patients received antiviral therapy (antiviral group), and 71 did not (non-antiviral group). The definition of low-level viremia was an HBV DNA level <2000 IU/ml. Kaplan-Meier curves, log-rank tests and Cox regression analysis were used for statistical analyses. The median follow-up duration was 39 months (1-174 months). Overall survival (OS) did not differ between groups (P = .227). Barcelona Clinic Liver Cancer stage (BCLC), Child-Pugh (CP) class and α-fetoprotein level were independent prognostic factors for OS. Antiviral therapy (hazard ratio [HR], 0.503, P = .022) was a prognostic factor for 2-year survival. On subgroup analysis, antiviral therapy improved short-term survival in patients with BCLC stage 0 and A (P = .037) and CP class A (P = .04). In patients with low-level viremia, antiviral therapy yielded short-term survival benefits, particularly in patients with early-stage HCC.

A new discovery of STAT4 single nucleotide polymorphisms associated with hepatocellular carcinoma risk in Chinese Han population: a case-control study

BACKGROUND

Hepatocellular carcinoma (HCC) is a common fatal malignant tumor worldwide. STAT4 is HCC susceptibility gene identified by genome-wide association study. The purpose of this study was to determine the association between four candidate single nucleotide polymorphisms (SNPs) in STAT4 genes and HCC risk in Chinese Han population.

METHODS

A case-control study was conducted to assess the association between STAT4 SNPs and HCC risk in 1011 Chinese Han population. Agena MassARRAY was used to genotype SNPs. The association between SNPs and HCC susceptibility under different genetic models was evaluated by logistic regression analysis. Multifactorial dimension reduction (MDR) analyzed the interaction of 'SNP-SNP' in HCC risk. The difference of clinical characteristics between different genotypes was completed by ANOVA.

RESULTS

The results showed that STAT4 rs11889341 was significantly associated with HCC risk under multiple genetic models (homozygote: OR = 0.60, p = 0.033; recessive: OR = 0.63, p = 0.028; log-additive: OR = 0.83, p = 0.032). The results of subgroup analysis showed that STAT4 rs11889341 is significantly associated with HCC risk with participants who were > 55 years, male or smoking. Both STAT4 rs7574865 and rs10174238 were significantly associated with HCC risk among participants who were > 55 years old, smoking or drinking. STAT4 haplotype (Trs11889341Trs7574865) could reduce the risk of HCC. In addition, rs11889341 and rs7574865 were significantly associated with the level of serum ferritin.

CONCLUSION

STAT4 rs11889341, rs7574865 or rs10174238 is potentially associated with HCC risk in Chinese Han population. In particular, rs11889341 showed outstanding association with HCC risk.

Nucleos(t)ide analogues and Hepatitis B virus-related hepatocellular carcinoma: A literature review

Hepatitis B virus is mainly considered to cause hepatocellular carcinoma which is the fourth leading cause of cancer-related mortality worldwide. Treatment of Hepatitis B virus with nucleos(t)ide analogues can decrease the progression of the disease and subsequently decreases the incidence of hepatocellular carcinoma. In this review, we have discussed the different classes of nucleos(t)ide analogues used in the treatment of Hepatitis B virus and their relationship with the development of hepatocellular carcinoma. Furthermore, we discussed the effect of treatment of Hepatitis B virus with Nucleoside analogues (NAs) before, during and after surgery, chemoembolization, radiofrequency ablation, and chemotherapy for the treatment of hepatocellular carcinoma.

Evaluation of the Benefits of TACE Combined with Sorafenib for Hepatocellular Carcinoma Based on Untreatable TACE (unTACEable) Progression

Purpose

Outcomes after the treatment for unresectable or advanced-stage hepatocellular carcinoma (HCC) are unsatisfied. We evaluated the therapeutic benefits of a combination therapy strategy for these patients through transarterial chemoembolization (TACE) plus sorafenib.

Patients and Methods

In total, 85 patients with HCC classified as intermediate and advanced stage from June 2012 to November 2017 were retrospectively investigated. We divided patients into the monotherapy (n=43; TACE alone) and combined therapy (n=42; TACE plus sorafenib) groups.

Results

Compared with the TACE alone group, the TACE plus sorafenib experienced significantly prolonged progression-free survival (PFS) (mean 21 months vs 12 months; P = 0.0005) and overall survival (OS) (mean 32 months vs 21 months; P = 0.0157). The disease control rate (DCR) of TACE plus sorafenib group was 80.95%, which was significantly increased than the TACE alone group (55.81%) (P<0.05), as well as objective response rate (ORR) (23.81% vs 16.28%). Besides, the rates of liver-related AEs and liver failure in the TACE plus sorafenib group were not increased in contrast to TACE alone group, and there were no new safety concerns. To sum up, the superiority of combination therapy with significantly prolonging progression-free and overall survival was observed, meanwhile finding a significant increase in tumor response rate and manageable safety in the combined therapy in contrast to the monotherapy group.

Conclusion

Based on unTACEble progression, the superiority of the combination therapy is that TACE plus sorafenib has been bringing about significantly better outcomes compared with TACE alone for HCC patients.

Effects of Antiviral Therapy on HBV Reactivation and Survival in Hepatocellular Carcinoma Patients Undergoing Hepatic Artery Infusion Chemotherapy

Background

This study aimed to investigate the influence of hepatic artery infusion chemotherapy (HAIC) on hepatitis B virus (HBV) reactivation in hepatitis B surface antigen (HBsAg) positive patients with primary hepatocellular carcinoma (HCC) as well as evaluate the role of antiviral prophylaxis in these patients.

Methods

We enrolled 170 HBsAg-positive advanced HCC patients receiving HAIC using mFOLFOX regimen, of which 137 patients received antiviral prophylaxis. Risk factors for HBV reactivation were analyzed. The overall survival (OS) from the first application of HAIC were compared between antiviral and non-antiviral groups.

Results

A total of 25 patients (14.7%) developed HBV reactivation after HAIC, of which 16 patients received antiviral treatment and nine patients did not. The incidence of HBV reactivation was 11.7% (16/137) in antiviral group and 27.3% (9/33) in non-antiviral group respectively. No antiviral prophylactic was the only significant risk factor for HBV reactivation (OR=12.35, 95% confidence interval (CI) 4.35–33.33, p<0.001). Patients in antiviral group received more cycles of HAIC compared with non-antiviral group (3.11 ± 1.69 vs 1.75 ± 1.18, p<0.05) at the time of HBV reactivated. Seven of the 25 HBV reactivation patients developed hepatitis. OS in antiviral group was significantly longer than that of non-antiviral group (median 16.46 vs 10.68 months; HR=0.57; 95% CI, 0.36–0.91; p<0.05).

Conclusions

HBV reactivation is more prone to occur in the HBsAg-positive HCC patients undergoing HAIC without antiviral prophylaxis. Regular monitoring of HBV DNA and antiviral prophylaxis are suggested to prevent HBV reactivation as well as prolong the OS of these patients.

Control strategy design for the anti-HBV mathematical model

Currently, the anti-viral therapy has been extensively utilised to reduce the viral burden and switch off certain infectious sources for hepatitis B virus (HBV) infected patients in clinical treatment. Several pieces of existing evidence have demonstrated that large-scale coverage with anti-viral therapy has obtained a certain great contribution in hygiene and disease control. In this study, an anti-HBV mathematical model is considered and its control strategy of the drug treatment is designed. Based on the Lyapunov theory, this study derives three main theorems to propose three different control strategies, respectively, for drug treatments [inline-formula removed] and [inline-formula removed], such that all states of the anti-HBV model can finally converge to the infection-free equilibrium point [inline-formula removed] asymptotically. Especially, the designed drug treatment [inline-formula removed] or [inline-formula removed] is not a fixed value, but it is time-varying and dependent on states. In Theorem 1, the single drug treatment [inline-formula removed] without [inline-formula removed] is synthesised. Theorem 2 considers the single drug treatment [inline-formula removed] without [inline-formula removed]. In Theorem 3, the combination therapy of [inline-formula removed] and [inline-formula removed] is designed. Finally, there are several simulations to show that the proposed combination therapy is much more effective to cure HBV infected patients than the drug treatment with solely single [inline-formula removed] or single [inline-formula removed].

Screening and Prophylaxis to Prevent Hepatitis B Reactivation: Other Populations and Newer Agents

Because of the relatively high prevalence of both hepatitis B infection and various forms of autoimmune inflammatory diseases treated with aggressive immunotherapy, reactivation of hepatitis B occurs in a substantial number of patients. The risk of reactivation depends on the degree and duration of immunosuppression. A large number of drug treatments have resulted in reactivation of hepatitis B virus infection and, based on the mechanisms and extent of immunosuppression, recommendations for some of the newer classes of immunosuppressive drugs are provided.

What Comes First: Treatment of Viral Hepatitis or Liver Cancer?

Chronic hepatitis B virus (HBV) and hepatitis C virus (HCV) infection are the most important underlying causes for the development of hepatocellular carcinoma (HCC) worldwide. Determining the optimal approach for management of the viral infection and the HCC depends on the virus and the stage of the cancer. In patients with HCV-associated HCC, there are multiple reasons to first treat the HCC. Firstly, in case of a curable HCC, the urgency for HCC treatment is important to avoid progression during HCV treatment. Secondly, the presence of HCC itself appears to reduce the rates of sustained virological response (SVR) achieved with direct-acting antivirals (DAAs). And finally, the evidence does not support the concept of an increase in HCC recurrence due to DAAs, so a patient can safely be treated after HCC cure. For patients with very advanced HCC, the benefits of HCV therapy are questionable. In contrast, those who develop HCC in the setting of chronic HBV infection, treatment with nucleoside analogues (NAs) is recommended prior to treating HCC, to prevent further liver injury and reduce the risk for HCC recurrence. Ultimately, earlier diagnosis and treatment of HBV and HCV will hopefully reduce the incidence of HCC worldwide.
