Hepatitis C-related hepatocellular carcinoma in the era of new generation antivirals
BMC Medicine volume 15, Article number: 52 (2017)
Hepatitis C virus infection is a major cause of hepatocellular carcinoma worldwide. Interferon has been the major antiviral treatment, yielding viral clearance in approximately half of patients. New direct-acting antivirals substantially improved the cure rate to above 90%. However, access to therapies remains limited due to the high costs and under-diagnosis of infection in specific subpopulations, e.g., baby boomers, inmates, and injection drug users, and therefore, hepatocellular carcinoma incidence is predicted to increase in the next decades even in high-resource countries. Moreover, cancer risk persists even after 10 years of viral cure, and thus a clinical strategy for its monitoring is urgently needed. Several risk-predictive host factors, e.g., advanced liver fibrosis, older age, accompanying metabolic diseases such as diabetes, persisting hepatic inflammation, and elevated alpha-fetoprotein, as well as viral factors, e.g., core protein variants and genotype 3, have been reported. Indeed, a molecular signature in the liver has been associated with cancer risk even after viral cure. Direct-acting antivirals may affect cancer development and recurrence, which needs to be determined in further investigation.
Chronic infection of hepatitis C virus (HCV), estimated to affect more than 150 million individuals globally, has proven a major health problem by causing liver cirrhosis and cancer. Hepatocellular carcinoma (HCC), the major liver cancer histological type, is the second leading cause of cancer mortality worldwide . Interferon-based regimens have been the mainstay of anti-HCV therapy, yielding HCV cure, or sustained virologic response (SVR), in approximately 50% of patients . Recently developed direct-acting antivirals (DAAs), which directly target the viral protease, polymerase, or non-structural proteins, have enabled interferon-free anti-HCV therapies with a revolutionary improvement of SVR rate, approaching or surpassing 90% . Despite the unprecedentedly high antiviral efficacy, access to therapy remains limited, at less than 10% of the total number of HCV-infected individuals, especially in developing countries, due to the high drug costs [4, 5]. In addition, the high frequency of unrecognized HCV infection in the general and specific (e.g., inmates and homeless) populations, estimated at 50% or above of infected individuals, hampers control of the virus even with the commercialization of DAAs [5, 6]. With the 3–4 million newly infected cases each year, it is estimated that the HCV-associated disease burden will remain high in the next decade, even in developed countries [7–9].
Wider use of DAAs has revealed several limitations, including more refractory genotype 1a or 3 virus, emergence of resistant HCV stains with characteristic resistance-associated substitutions, and poorer response in prior non-responders to interferon-based therapies . These findings warrant further development of alternative strategies such as the application of specific DAA combination therapies to target resistant HCV strains, host targeting agents/viral entry inhibition, and the development of diagnostic tools to monitor therapeutic progress and success [11–14]. Even after SVR, re-infection can occur in up to 10–15% of patients, especially in high-risk populations such as injection drug users [15–17]. Post-transplantation graft re-infection is also a critical issue given that most liver explants (67%) remain HCV RNA positive in the liver despite undetectable blood HCV RNA . In these clinical scenarios, a prophylactic vaccine is likely to be an effective option. Although HCV vaccine development is challenging due to the high viral genetic variability, promising progress has been made to date . Thus, complementary antiviral approaches including improved and more accessible therapies as well as the development of a prophylactic vaccine will be necessary to achieve impactful global control of infection that leads to HCV eradication, namely a reduction of regional incidence close to zero.
Effect of HCV cure on HCC development
HCV-induced progressive liver fibrosis and aging are well-established high-risk conditions for HCC development (Fig. 1) . Of note, the highly carcinogenic “field effect” in fibrotic/cirrhotic livers leads to repeated recurrence of de novo HCC tumors even after curative treatment of the initial primary tumors. The effect of achieving an SVR on HCC risk has been reported in multiple retrospective cohorts of patients who were mostly treated with interferon-based therapies (Table 1); these studies consistently showed significant reduction of HCC incidence in SVR patients. A pooled analysis of 12 observational studies with a total of 25,497 patients showed that interferon-induced SVR resulted in an approximately four-fold reduction of HCC risk irrespective of liver disease stage (hazard ratio, 0.24; P < 0.001) . Annual HCC incidence in patients with advanced liver fibrosis or cirrhosis and active HCV infection is reported to range from 1% to 8% , reducing to 0.07% to 1.2% after achieving an SVR by interferon-based therapies (Table 1). SVR is also implicated in reduction of all-cause mortality, which may alter patient prognosis to the level of the general population, although this is yet to be established [20, 21]. In cirrhotic patients who failed to achieve SVR, subsequent maintenance low-dose interferon treatment reduced annual HCC incidence to 1.2% when compared to 4.0% in untreated patients (hazard ratio, 0.45; P = 0.01) . This result suggests that the anti-inflammatory and/or immunomodulatory effects of interferon may have HCC-preventive effects irrespective of HCV presence, although the adverse effects (flu-like symptoms, neuropsychiatric and myelosuppressive effects) hamper its wider use . DAAs are shown to be less toxic, and are expected to overcome the limitations of interferon-based therapies. DAAs were indeed well-tolerated even in compensated and decompensated cirrhosis patients in recent clinical trials [23, 24]. However, their HCC preventive effect is still only partially understood.
Projected trend of HCV HCC incidence with new generation anti-HCV therapies
HCC is the most rapidly increasing cause of cancer death, with HCV as the major etiology affecting generally more than half of HCC patients in developed countries such as the USA . HCV incidence increases are more prominent in specific subpopulations such as the 1945–1965 birth cohort (baby boomers) in the USA, in whom a 64% incidence was observed between 2003 and 2011; such an incidence is estimated to result in more than one million HCV-related cirrhosis and/or HCC by 2020, with increasing HCC incidence until 2030 [26–28]. In US veterans, HCC incidence has increased by 2.5-fold and mortality has tripled since 2001, driven overwhelmingly by HCV . In a regional population in Australia, in contrast to the decreased incidence of hepatitis B virus (HBV)-related HCC due to clinical implementation of the antivirals, anti-HCV therapies had no impact on HCV-related HCC risk between 2000 and 2014 . Despite the anticipated improvement in SVR rate with wider use of DAAs, model-based simulation studies have predicted further increases of HCC incidence over the next decade – even with SVR rates of 80–90% by DAAs, predicted HCC incidence will continue to increase until 2035 unless the current annual treatment uptake rate (1–3%) is increased by more than five-fold by 2018 [9, 31, 32]. These studies clearly highlight the urgent need for identification of undiagnosed HCV infection by implementing HCV screening programs targeting high-risk populations as well as improved access to new generation anti-HCV therapies with reduced costs and streamlined treatment intake and follow-up .
Post-SVR HCC risk factors
It is noteworthy that SVR does not necessarily mean elimination of HCC risk despite the substantially decreased incidence. In fact, HCC can occur even more than 10 years after successful HCV clearance (Table 1). The annual post-SVR HCC incidence of approximately 1% is still higher than the cancerous conditions in other organs, and the volume of HCC-developing patients will remain substantial given the vast size of the HCV-infected population .
Retrospective interrogation of previously treated patients mostly by interferon-based regimens revealed several post-SVR HCC-associated clinical variables, most of which are known HCC risk factors in patients with active HCV infection (Table 2). More advanced liver fibrosis as well as biochemical or imaging surrogates of histological fibrosis (e.g., serum albumin, platelet count, fibrosis-4 index, aspartate aminotransferase-to-platelet ratio index, elastography-based liver stiffness) before and/or after antiviral treatment are the most prominent features associated with higher post-SVR HCC risk. Older age, alcohol abuse, accompanying metabolic disorders (especially diabetes), and persisting hepatic inflammation, e.g., high aspartate aminotransferase, were also associated with HCC risk. Serum alpha-fetoprotein levels pre- and post-SVR have also been implicated as a risk indicator, with relatively low cut-off values ranging from 5 to 20 ng/mL. In addition to the host factors, post-SVR HCC-associated pre-treatment viral factors have been identified, suggesting that HCV leads to irreversible changes in cellular signaling via mechanisms such as epigenetic activation or imprinting, which continue to drive carcinogenesis even after viral clearance. A variant in genotype 1b HCV core protein, Gln70(His70), was associated with increased HCC incidence post-SVR, with a hazard ratio of 10.5, in a cohort of 1273 interferon-treated Japanese patients . Interestingly, the variant can induce cancer-related transcriptional dysregulation in an HCV-infectious cell system . HCC risk association of genotype 3 was also found in a cohort of 10,817 US veterans . A further study suggested differences in molecular aberrations in HCC tumors from SVR livers compared to tumors in livers with active HCV infection, which may represent SVR-specific mechanisms of carcinogenesis .
Current practice guidelines recommend regular biannual HCC screening for cirrhotic patients with active HCV infection, but it is still undetermined whether and how post-SVR patients should be monitored for future HCC development and if any of the risk-associated variables has clinical utility . Molecular hallmarks of persisting HCC risk in post-SVR livers may serve as biomarkers to identify a subset of patients still at risk and should be therefore monitored by regular HCC screening. A pan-etiology HCC risk-predictive gene signature in the liver, which was shown to predict post-SVR HCC development, may serve as a biomarker to identify a subset of SVR patients who should be regularly monitored for future HCC .
Post-DAA HCC development and recurrence
Accumulating clinical experience of DAA-based treatment has suggested that post-SVR HCC development and recurrence may be more frequent compared to interferon-based treatment (Table 2). In a small series of HCC patients who achieved an SVR by all-oral DAAs after HCC treatment, tumor recurrence rates of approximately 30% within 6 months were reported; these rates are alarmingly high, however, the observation period was short, a proper control group was lacking, and the finding was not replicated in a subsequent study [39–43]. Further studies are needed to clarify whether DAAs increase HCC incidence and to determine the natural history and baseline post-SVR HCC incidence according to the type of anti-HCV therapy in each specific patient population. Interestingly, chronic hepatitis B patients treated with directly-acting anti-HBV drugs, entecavir or other nucleos(t)ide analogues, showed higher HCC incidence compared to peg-interferon-treated patients, suggesting that the difference in HCC-suppressive effect may be a common phenomenon across different hepatitis viruses .
Several studies suggested a possibly distinct difference in host immune modulation between interferon and DAAs. Rapid decline of HCV viral load by DAAs was experimentally or clinically associated with restored HCV-specific, often exhausted, CD8+ T cell function, memory T cell re-differentiation and lymphocyte deactivation, and normalized NK cell function [45–48], all of which may indicate a quick loss of anti-HCV immune responses. Interestingly, reactivation of other co-infected viruses, such as herpes virus, was observed after DAA-based anti-HCV therapy , suggesting simultaneous loss of bystander immune response to the viruses and possibly to neoplastic cells, which may lead to higher HCC recurrence after DAA treatment. On the other hand, complete remission of follicular lymphoma after DAA-based therapy was reported, suggesting that the influence of DAA-based SVR on cancer may vary according to cancer types and biological/clinical contexts .
HCV-related HCC will remain a major health problem in the coming decades despite the clinical deployment of DAAs. Access to the new generation antiviral therapies should be substantially improved to achieve meaningful prognostic benefit at the population level. The development of a vaccine remains an important goal for global control and eradication of infection. Post-SVR HCC is an emerging problem, with urgent unmet needs for the clinical strategy of early tumor detection and intervention, as well as elucidation of its molecular mechanisms for therapeutic target and biomarker discovery. Prolonged clinical observation should be further accumulated to determine the impact of DAA-induced SVR on HCC development and recurrence as well as on other cancer types.
