Abstract
The etiology of the majority of human cancers is associated with a myriad of environmental causes, including physical, chemical, and biological factors. DNA damage induced by such mutagens is the initial step in the process of carcinogenesis resulting in the accumulation of mutations. Mutational events are considered the major triggers for introducing genetic and epigenetic insults such as DNA crosslinks, single- and double-strand DNA breaks, formation of DNA adducts, mismatched bases, modification in histones, DNA methylation, and microRNA alterations. However, DNA repair mechanisms are devoted to protect the DNA to ensure genetic stability, any aberrations in these calibrated mechanisms provoke cancer occurrence. Comprehensive knowledge of the type of mutagens and carcinogens and the influence of these agents in DNA damage and cancer induction is crucial to develop rational anticancer strategies. This review delineated the molecular mechanism of DNA damage and the repair pathways to provide a deep understanding of the molecular basis of mutagenicity and carcinogenicity. A relationship between DNA adduct formation and cancer incidence has also been summarized. The mechanistic basis of inflammatory response and oxidative damage triggered by mutagens in tumorigenesis has also been highlighted. We elucidated the interesting interplay between DNA damage response and immune system mechanisms. We addressed the current understanding of DNA repair targeted therapies and DNA damaging chemotherapeutic agents for cancer treatment and discussed how antiviral agents, anti-inflammatory drugs, and immunotherapeutic agents combined with traditional approaches lay the foundations for future cancer therapies.

Clinical outcomes of direct-acting antiviral treatments for patients with hepatitis C after hepatocellular carcinoma are equivalent to interferon treatment. Hepatol Res 2020; 50:1118-1127. [PMID: 32678925 DOI: 10.1111/hepr.13547] [Citation(s) in RCA: 11] [Impact Index Per Article: 2.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/24/2020] [Revised: 06/16/2020] [Accepted: 07/11/2020] [Indexed: 12/13/2022]
Abstract
AIM It remains unclear how direct-acting antiviral (DAA) treatments influence hepatocellular carcinoma (HCC) recurrence and survival in comparison with interferon (IFN). METHODS In total, 338 patients with chronic hepatitis C virus (HCV) infection and previous HCC treatments who initiated IFN (N = 88, IFN group) or DAA treatment (N = 250, DAA group) from January 2005 to November 2017 at 23 hospitals and achieved sustained virologic response (SVR) were analyzed. Cumulative HCC recurrence and survival rates were compared between the two groups using propensity score (PS) matching. RESULTS After PS matching, 63 patients were selected for each group. The cumulative HCC recurrence rates at 1 and 3 years were 20.6% and 34.6% in the IFN group and 19.2% and 43.0% in the DAA group, respectively; the difference in cumulative HCC recurrence rates between the two groups was not significant (P = 0.332). No significant differences in HCC recurrence patterns were observed between the two groups. Overall survival rates at 1 and 3 years were 100% and 96.6% in the IFN group and 100% and 96.4% in the DAA group, respectively; the difference in overall survival rates between the two groups was not significant (P = 0.132). No significant differences in HCC recurrence and overall survival rates were observed between the two groups in subgroup analyses of patients receiving curative treatment (liver resection or radiofrequency ablation) for the most recent HCC before HCV treatment. CONCLUSIONS The recurrence rates and patterns of HCC and overall survival rates do not differ between SVR patients receiving IFN and DAA treatments.

Systematic review with meta-analysis: effectiveness of direct-acting antiviral treatment for hepatitis C in patients with hepatocellular carcinoma. Aliment Pharmacol Ther 2020; 51:34-52. [PMID: 31808566 DOI: 10.1111/apt.15598] [Citation(s) in RCA: 18] [Impact Index Per Article: 4.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/03/2019] [Revised: 07/25/2019] [Accepted: 11/06/2019] [Indexed: 02/06/2023]
Abstract
BACKGROUND Direct-acting antiviral (DAA) therapy for hepatitis C virus (HCV) infection is highly curative and tolerable. Among patients with hepatocellular carcinoma (HCC), optimal timing of DAA therapy remains unclear. Data on efficacy of DAA therapy in patients with HCC would inform this decision-making. AIM To evaluate response to DAA therapy among patients diagnosed with HCV infection and HCC. METHODS Bibliographic databases and conference abstracts were searched. Meta-analysis was conducted to pool sustained virologic response (SVR) estimates. RESULTS Fifty-six studies with 5522 patients with HCV and HCC were included. Overall SVR was 88.3% (95% CI 86.1-90.4). Twenty-seven studies included patients with prior or present HCC (n = 3126) and patients without HCC (n = 49 138), in which SVR was 88.2% (95% CI 85.0-91.4) and 92.4% (95% CI 91.1-93.7) among patients with and without HCC, respectively (odds ratio: 0.54, 95% CI 0.43-0.68, P < .001). In the subgroup analyses, higher SVR was seen in patients who received curative HCC management (SVR 90.4%, 95% CI 88.3-92.4), or treated with sofosbuvir + NS5A inhibitor DAAs (SVR 96.9%, 95% CI 94.3-99.4), or in patients with HCV genotype 1 infection (SVR 92.0%, 95% CI 88.1-95.6). CONCLUSION Response to DAA therapy was lower in patients with HCC compared to those without HCC, regardless of cirrhosis status. Among HCC patients, there was an impact of proportion with curative HCC management on DAA therapy response.

Timely eradication of HCV viremia by PegIFN/RBV is crucial in prevention of post RFA recurrence in CHC-HCC patients. J Formos Med Assoc 2018; 118:1239-1246. [PMID: 30581103 DOI: 10.1016/j.jfma.2018.11.014] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/22/2018] [Revised: 11/07/2018] [Accepted: 11/28/2018] [Indexed: 12/19/2022] Open
Abstract
BACKGROUND Secondary prevention of hepatocellular carcinoma (HCC) among patients with chronic hepatitis C (CHC) who achieve sustained virologic response (SVR) with interferon-based therapy has been proved effective. However, tertiary prevention with PegIFN/RBV therapy of HCC recurrence seems limited effect in CHC-HCC patients post curative therapies. This study aims to investigate the timing and impact of PegIFN/RBV treatment on prevention of HCC recurrence in patients after RFA treatment. METHODS From 2013 to 2016, a total of 137 CHC-HCC patients from a 508 patient based cohort receiving complete RFA treatment in Chang Gung Memorial Hospital, Linkou Medical Center were retrospectively recruited. Pre-RFA patient demographics were analyzed by cox regression analysis for prediction on tumor recurrence. Statistics analysis was performed with SPSS V.20 (IBM, USA). RESULTS The mean age of the 137 patients were 69.6 year-old and 71.5% of patients were cirrhotic. After propensity score matching, one hundred and two patients were enrolled into the analysis. Fifty-one patients (50%) received PegIFN/RBV therapy and twenty-seven patients (52.9%) achieved SVR. Patients who could achieve SVR had lower tumor recurrence rate than non-SVR and untreated groups (29.6% vs. 66.7% vs. 49.0%, P = 0.030). The effect is more prominent in those achieve SVR prior to compared with after RFA despite not reach statistically significant (26.1% vs. 50.0%, P = 0.334). CONCLUSION Timely treatment with SVR achievement has the lowest tumor recurrence rate in CHC-HCC patients. Secondary prevention might be even more important than tertiary prevention in CHC patients, especially regarding prevention of post RFA HCC recurrence.

Abstract
BACKGROUND Preoperative hepatitis C virus (HCV) viral load is known to predict long-term outcomes after hepatectomy for HCV-related hepatocellular carcinoma (HCC). This study sought to examine the hypothesis that postoperative and preoperative HCV viral-load have similar prognostic implications, as well as determine a target viral-load that will improve long-term postoperative outcomes. METHOD One hundred and eighty-one patients who underwent curative hepatectomy for HCV-related HCC were divided into five groups according to time-weighted average viral load. The cumulative-recurrence curves of the five groups were compared to identify prognostic trends. The optimal cut-off viral load value related to recurrence was also investigated. RESULTS The five cumulative-recurrence curves were separated into two clusters according to viral load. Patients with a negative viral load had comparable recurrence curves to patients with the lowest viral-load (P = 0.907); both of these patient groups had more favorable outcomes than patients with a viral load categorized in the other groups (all P < 0.050). The optimal cut-off based on maximum HR method (> or ≤4.0 log10 IU/mL) was a strong prognostic indicator of recurrence in multivariate analysis (HR 3.09; 95%CI 1.96-5.04; P < 0.001). CONCLUSION Postoperative HCV viral load correlated with long-term surgical outcomes. A low viral load (≤4.0 log10 IU/mL) independently predicted better long-term outcomes.

Abstract
BACKGROUND & AIMS Hepatitis C virus (HCV) treatment for patients with hepatocellular carcinoma (HCC) was uncommon before direct-acting antiviral (DAA) medications. Real-world effectiveness of DAAs for HCV in patients with HCC is unclear. We describe rates of sustained virologic response (SVR) with DAA regimens by HCV genotype in patients with a history of HCC. METHODS We identified patients who initiated antiviral treatment between January 1, 2014 and June 30, 2015 in the national Veterans Affairs health care system. Regimens included sofosobuvir, ledipasvir/sofosbuvir, and paritaprevir/ritonavir/ombitasvir and dasabuvir with or without ribavirin. HCC patients were divided into those who were treated with liver transplantation after HCC diagnosis ("HCC/LT" group) and those treated with other modalities prior to antiviral therapy ("HCC" group). RESULTS Of 17,487 HCV treatment recipients, 624 (3.6%) had prior HCC, including 142 with HCC/LT and 482 with HCC. Overall SVR was 91.1% in non-HCC, 74.4% in HCC, and 94.0% in HCC/LT. Among HCC patients, genotype 1 had the highest SVR overall (79.1% in HCC and 96.4% in HCC/LT), and genotype 3 the lowest (47.0% in HCC and 88.9% in HCC/LT). After adjustment for confounders, the presence of HCC was associated with lower likelihood of SVR overall (AOR 0.38 [95% CI 0.29, 0.48], p<0.001). CONCLUSION HCV can be cured with DAAs in the majority of patients with prior HCC, and in virtually all HCC patients post-liver transplant. Deferral of HCV treatment until the post-transplant setting may be considered among HCC patients listed for transplantation. LAY SUMMARY Over three-quarters of patients with hepatocellular carcinoma who have hepatitis C can achieve viral cure with direct-acting antiviral drugs. Among patients with hepatocellular carcinoma who subsequently received liver transplantation, over 90% of patients can achieve viral cure.

[PMID: 27861842 DOI: 10.1002/ijc.30521] [Citation(s) in RCA: 37] [Impact Index Per Article: 4.6] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/16/2016] [Revised: 10/06/2016] [Accepted: 11/02/2016] [Indexed: 12/14/2022]
Abstract
Antiviral therapy with interferon based therapies (IBT) has shown potential in improving survival in patients who have undergone resection or locoregional therapy for hepatitis C-associated hepatocellular carcinoma (HCV-HCC). However, this benefit has not been definitively ascribed to sustained viral response (SVR). Since IBT has been replaced with new directly acting agents (DAA), which are more efficacious in the treatment of HCV, we sought to better determine the prognostic impact of SVR in HCV-HCC. A systematic search of MEDLINE and EMBASE from inception through October 2015 was performed to identify studies that described the impact of presence of SVR in patients who underwent curative treatment of HCV-HCC. Summary hazard ratio (HR) with 95% confidence intervals (CI) was estimated for recurrence-free survival (RFS) and overall survival (OS) utilizing a random-effects model. After reviewing 858 abstracts, ten studies which included a total of 1,794 patients were selected and data was extracted. Of these ten studies, the impact of SVR on RFS and OS was reported in eight and seven studies respectively. In a meta-analysis which included 1,519 patients, SVR was associated with improved OS (HR 0.18; 95% CI 0.11-0.29, I2 = 2%). We also found that SVR was associated with better RFS in a meta-analysis (1,241 patients; HR 0.50; 95% CI 0.40-0.63, I2 = 0). In conclusion, SVR is associated with improved OS and RFS in patients with HCV who have undergone resection or locoregional therapy for HCC. Newer DAA therapies which offer increased tolerability and viral eradication should be considered as adjunctive therapy.

Abstract
Hepatitis C infection represents a global health problem affecting ∼200 million chronically infected patients worldwide. Owing to the development of a fibrogenic and inflammatory micromilieu in the liver, hepatitis C virus (HCV)-infected patients are at a high risk of developing fibrosis, cirrhosis and hepatocellular carcinoma (HCC). The advent of direct-acting antiviral agents (DAAs), however, has spurred a revolution in the treatment of HCV patients with sustained viral response (SVR) rates exceeding 90% in real-life settings. Recent clinical trials suggest that these novel treatments will not only alter the epidemiology of HCV infection but also the incidence of HCV-induced complications including hepatic decompensation, liver transplantation and hepatocarcinogenesis. Here, we summarize data from clinical trials carried out in HCV patients with compensated and decompensated cirrhosis and analyze the impact of viral clearance on HCC development and treatment. Finally, we review and discuss current and future treatment options of HCV patients with HCC in pre- and post-transplantation settings.
