Adherence to a Semiannual Surveillance Program for Hepatocellular Carcinoma in Patients With Liver Cirrhosis

Abstinence is associated with better outcomes in patients with alcohol-related hepatocellular carcinoma: Results of an observational study

BACKGROUND

Patients with alcohol-related cirrhosis and hepatocellular carcinoma (HCC) may have reduced survival compared to those with HCC related to other causes. The impact of abstinence in alcohol-related HCC is unknown. We compared access to curative treatment and the prognosis of patients with HCC according to the cause of cirrhosis and evaluated the impact of abstinence on the prognosis of patients with alcohol-related HCC.

PATIENTS AND METHODS

Data for patients with cirrhosis and HCC were prospectively collected in a single center. A logistic regression model was used to identify factors associated with access to curative treatment. Multivariate Fine and Gray proportional hazards models were used to identify factors associated with 5-year survival after adjustment for lead-time bias.

RESULTS

Two hundred patients were included, 114 (57 %) with non-alcohol-related HCC and 86 (43 %) with alcohol-related HCC (35 abstainers, 51 consumers). During follow-up, 21 patients were transplanted and 156 died. The proportion of patients who had access to curative treatment was 65 % in abstainers, 44 % in consumers, and 57 % in patients with non-alcohol-related cirrhosis (p = 0.06). In multivariate analyses, abstinence was not associated with better access to curative treatment. After adjustment for lead-time bias, the 5-year cumulative incidence of overall death was significantly lower in abstainers than in consumers and in patients with non-alcohol-related cirrhosis (52 % vs. 78 % vs. 81 %, respectively, p = 0.04). In multivariate analyses, abstainers had lower risk of death than consumers (SHR: 0.47, 95 % CI: 0.28-0.80, p = 0.005).

CONCLUSION

Abstinence improves the outcome of patients with alcohol-related cirrhosis once HCC has occurred.

Factors associated with nonadherence to surveillance for hepatocellular carcinoma among patients with hepatic C virus cirrhosis, 2000-2015

Hepatocellular carcinoma (HCC) surveillance can detect the early stage of tumors and lead to improved survival. Adherence to guideline-concordant HCC surveillance is crucial in at-risk populations, including patients with hepatic C virus (HCV) cirrhosis. This study was conducted to identify patient and provider factors associated with nonadherence to HCC surveillance in patients with HCV cirrhosis. Data were primarily obtained from the Taiwan National Health Insurance Research Database for the 2000 to 2015 period. Adult patients newly diagnosed as having HCV cirrhosis between 2003 and 2012 were enrolled. Each patient was followed up for 3 years and until the end of 2015. Annual HCC surveillance was defined as the uptake of an abdominal ultrasound and alpha-fetoprotein (AFP) test annually during the 3-years follow-up. Nonannual surveillance was defined as the lack of an annual abdominal ultrasound and AFP test during the same 3-years period. Multinomial logistic regression models were applied to determine factors influencing adherence or nonadherence to annual HCC surveillance. We included a total of 4641 patients with HCV cirrhosis for analysis. Of these patients, only 14% adhered to annual HCC surveillance. HCC surveillance improved in later years, compared with the earlier phases of the study period. Patients with HCV cirrhosis comorbid with coronary artery disease (CAD) or chronic obstructive pulmonary disease (COPD) or those with a relatively high number of comorbidities had a significantly higher likelihood of nonadherence. Patients who primarily received care from internists were significantly less likely to exhibit nonadherence to annual HCC surveillance compared with patients receiving care from physicians of other specialties. Patients who primarily received care from physicians practicing in larger hospitals were significantly less likely to exhibit nonadherence. HCC surveillance rates remain unacceptably low among high-risk patients, and our findings may be helpful in the development of effective interventions to increase HCC surveillance. The effective incorporation of HCC surveillance into routine visits for other chronic comorbidities, particularly for CAD or COPD, may be crucial for increasing HCC surveillance.

Health Behavior and Cancer Prevention among Adults with Li-Fraumeni Syndrome and Relatives in Germany-A Cohort Description

Li-Fraumeni-syndrome (LFS) is a rare, highly penetrant cancer predisposition syndrome (CPS) caused by pathogenic variants (PVs) in TP53. Physical activity (PA) and a Mediterranean diet lead to cancer reduction or survival benefits and increased quality of life (QoL), but this is yet unstudied among LFS. TP53 PV carriers (PVC) and their relatives were questioned on dietary patterns (Mediterranean Diet Adherence Screener), PA (Freiburg Questionnaire), QoL (Short-form-Health-Survey-12), smoking, alcohol consumption and perception of cancer risk in a German bi-centric study from March 2020-June 2021. The study enrolled 70 PVC and 43 relatives. Women compared to men (6.49 vs. 5.38, p = 0.005) and PVC to relatives (6.59 vs. 5.51; p = 0.006) showed a healthier diet, associated with participation in surveillance (p = 0.04) and education (diet p = 0.02 smoking p = 0.0003). Women smoked less (2.91 vs. 5.91 packyears; p = 0.03), psychological well-being was higher among men (SF-12: males 48.06 vs. females 41.94; p = 0.004). PVC rated their own cancer risk statistically higher than relatives (72% vs. 38%, p < 0.001) however, cancer risk of the general population was rated lower (38% vs. 70%, p < 0.001). A relative's cancer-related death increased the estimated personal cancer risk (p = 0.01). The possibilities of reducing cancer through self-determined health behavior among PVC and relatives has not yet been exhausted. Educating families with a CPS on cancer-preventive behavior requires further investigation with regard to acceptance and real-life implementation.

Impact of Alcohol Abstinence on the Risk of Hepatocellular Carcinoma in Patients With Alcohol-Related Liver Cirrhosis

INTRODUCTION

Although alcohol cessation is the only effective treatment for alcohol-related liver disease, few data exist concerning its influence on the risk of hepatocellular carcinoma (HCC). We aimed to evaluate the effect of alcohol abstinence on the incidence of HCC in patients with alcohol-related cirrhosis.

METHODS

We studied 727 patients with alcohol-related cirrhosis (247 with compensated disease and 480 with previous decompensation) who were included in a surveillance program for the early detection of HCC and prospectively followed. Baseline clinical and biological parameters and alcohol consumption during follow-up were recorded. Abstinence was defined as the absence of any alcohol use.

RESULTS

During follow-up (median 54 months), 354 patients (48.7%) remained abstinent and 104 developed HCC (2.3 per 100 person-years). Factors independently associated with the risk of HCC among patients with previous decompensation were age, male gender, and aspartate aminotransferase, whereas abstinence was not linked to a reduced risk (hazard ratio 0.95; 95% confidence interval 0.59-1.52). However, among patients without previous decompensation, prothrombin activity and abstinence were independently associated with the risk of HCC. Abstinent patients had a significant decrease in the risk of developing tumor (hazard ratio 0.35; 95% confidence interval 0.13-0.94). These results did not change after applying a competing risk analysis where death and liver transplantation were considered as competing events.

DISCUSSION

Alcohol abstinence reduced the risk of HCC in patients with alcohol-related cirrhosis, but only in those without a history of decompensated disease. This finding emphasizes the need for an early diagnosis of alcohol-related liver disease and for implementing strategies leading to an increase in the rate of achieving and maintaining abstinence among this population.

Surveillance of patients with cirrhosis remains suboptimal in the United States

BACKGROUND & AIMS

Regular monitoring/surveillance for liver complications is crucial to reduce morbidity and mortality in patients with cirrhosis. Recommendations from professional societies are available but adherence is not well studied, especially outside of academic centers. We aimed to determine the frequencies and factors associated with laboratory monitoring, and hepatocellular carcinoma (HCC) and esophageal varices (EV) surveillance in patients with cirrhosis.

METHODS

We identified 82,427 patients with cirrhosis (43,280 compensated and 39,147 decompensated) from the Truven Health MarketScan Research Database®, 2007-2016. We calculated the proportion of patients with cirrhosis with various frequencies of procedures/testing: laboratory (complete blood count, comprehensive metabolic panel, and prothrombin time), HCC and EV surveillance. We also used multivariable logistic regression to determine factors associated with having procedures.

RESULTS

The proportions of patients undergoing HCC surveillance (8.78%), laboratory testing (29.72%) at least every 6-12 months, or EV surveillance (10.6%) at least every 1-2 years were suboptimal. The majority did not have HCC (45.4%) or EV (80.3%) surveillance during the entire study period. On multivariable regression, age 41-55 (vs. <41) years, preferred provider organization (vs. health maintenance organization) insurance plan, specialist care (vs. primary care and other specialties), diagnosis between 2013-2016 (vs. 2007-2009), decompensated (vs. compensated) cirrhosis, non-alcoholic fatty liver disease (vs. viral hepatitis), and higher Charlson comorbidity index were associated with significantly higher odds of undergoing procedures/testing every 6-12 months and EV surveillance every 1-2 years.

CONCLUSIONS

Despite modest improvements in more recent years, routine monitoring and surveillance for patients with cirrhosis is suboptimal. Further efforts including provider awareness, patient education, and system/incentive-based quality improvement measures are urgently needed.

LAY SUMMARY

Patients with cirrhosis should undergo health monitoring for liver complications to achieve early detection and treatment. In a large nationwide cohort of 82,427 patients with cirrhosis in the United States, we found a low rate of adherence (well less than half) to routine blood test monitoring and surveillance for liver cancer and esophageal varices (swollen blood vessels in the abdomen that could lead to fatal bleeding). Adherence has increased in the recent years, but much more improvement is needed.

Inadequate Ultrasound Examination in Hepatocellular Carcinoma Surveillance: A Systematic Review and Meta-Analysis

We aimed to systematically evaluate the incidence of inadequate US in hepatocellular carcinoma (HCC) surveillance and determine the risk factors. Original studies reporting the incidence or risk factors for inadequate US were identified in MEDLINE, EMBASE, and the Cochrane database. The pooled incidence of inadequate US was calculated using a random effects model, and subgroup analyses were performed. The pooled odds ratio (OR) was calculated for each risk factor for inadequate US. Six eligible articles were identified from 756 screened articles (4250 patients). The pooled incidence of inadequate US was 21.5%. Significantly higher rates of inadequate US were noted in studies including patients with and without hepatic observations compared with those evaluating only patients with hepatic observations (23.2% vs. 18.8%), studies using US alone compared with US plus alpha-fetoprotein (28.0% vs. 20.8%), and those using pathology and imaging as a reference standard compared with imaging only (23.2% vs. 17.9%). Nonalcoholic steatohepatitis (OR = 2.3 (1.07–4.84)), Child–Pugh B cirrhosis (OR = 2.2 (1.10–4.37)), and high body mass index (OR = 2.2 (1.12–4.24)) were significant risk factors for inadequate US (p ≤ 0.04). In patients at risk of HCC, 21.5% of US surveillance was inadequate. An alternative surveillance modality might be considered in patients with risk factors.

Use of Hepatocellular Carcinoma Surveillance in Patients With Cirrhosis: A Systematic Review and Meta-Analysis

BACKGROUND AND AIMS

Hepatocellular carcinoma (HCC) surveillance is associated with early tumor detection and improved survival; however, it is often underused in clinical practice. We aimed to characterize surveillance use among patients with cirrhosis and the efficacy of interventions to increase surveillance.

APPROACH AND RESULTS

We performed a systematic literature review using the MEDLINE database from January 2010 through August 2018 to identify cohort studies evaluating HCC surveillance receipt or interventions to increase surveillance in patients with cirrhosis. A pooled estimate for surveillance receipt with 95% confidence intervals was calculated. Correlates of surveillance use were defined from each study and prespecified subgroup analyses. Twenty-nine studies, with a total of 118,799 patients, met inclusion criteria, with a pooled estimate for surveillance use of 24.0% (95% confidence interval, 18.4-30.1). In subgroup analyses, the highest surveillance receipt was reported in studies with patients enrolled from subspecialty gastroenterology/hepatology clinics and lowest in studies characterizing surveillance in population-based cohorts (73.7% versus 8.8%, P < 0.001). Commonly reported correlates of surveillance included higher receipt among patients followed by subspecialists and lower receipt among those with alcohol-associated or nonalcoholic steatohepatitis (NASH)-related cirrhosis. All eight studies (n = 5,229) evaluating interventions including patient/provider education, inreach (e.g., reminder and recall systems), and population health outreach strategies reported significant increases (range 9.4%-63.6%) in surveillance receipt.

CONCLUSIONS

HCC surveillance remains underused in clinical practice, particularly among patients with alcohol-associated or NASH-related cirrhosis and those not followed in subspecialty gastroenterology clinics. Interventions such as provider education, inreach including reminder systems, and population health outreach efforts can significantly increase HCC surveillance.

Risk Factors, Pathogenesis, and Strategies for Hepatocellular Carcinoma Prevention: Emphasis on Secondary Prevention and Its Translational Challenges

Hepatocellular carcinoma (HCC) is a leading cause of cancer-associated mortality globally. Given the limited therapeutic efficacy in advanced HCC, prevention of HCC carcinogenesis could serve as an effective strategy. Patients with chronic fibrosis due to viral or metabolic etiologies are at a high risk of developing HCC. Primary prevention seeks to eliminate cancer predisposing risk factors while tertiary prevention aims to prevent HCC recurrence. Secondary prevention targets patients with baseline chronic liver disease. Various epidemiological and experimental studies have identified candidates for secondary prevention-both etiology-specific and generic prevention strategies-including statins, aspirin, and anti-diabetic drugs. The introduction of multi-cell based omics analysis along with better characterization of the hepatic microenvironment will further facilitate the identification of targets for prevention. In this review, we will summarize HCC risk factors, pathogenesis, and discuss strategies of HCC prevention. We will focus on secondary prevention and also discuss current challenges in translating experimental work into clinical practice.

Hepatitis C Antiviral Therapy In Patients With Successfully Treated Hepatocellular Carcinoma: Dancing With Wolves

Hepatitis C virus (HCV) infection is known to be one of the leading causes of hepatocellular carcinoma (HCC) all over the world. Previously, multiple studies have confirmed a decreased rate of HCC occurrence or recurrence in the cases of hepatitis C associated cirrhosis after treatment with interferon, in comparison to the untreated cases, even in the absence of clearance of HCV. Treatment programs with direct-acting antivirals (DAAs) as a new method for HCV treatment and cure in 2014, with higher safety and efficacy, were considered as an important step in the treatment of patients with history of HCC, improving their overall prognosis. Recently, reports coming from various European centers claimed that the risk of HCC increased following DAAs therapy, especially in cases with previous HCC. Moreover, other studies revealed that the recurrence of HCC after DAAs treatment was more aggressive. Even though others were not able to conclude the same results, the role of DAA therapy in recurrence of HCC in patients with previous HCC after sustained virological response (SVR) achievement remains questionable. This review explored the existing literature and discussed opinions on the possibility of increasing recurrence of HCC following DAA therapy, possible mechanisms, predictors of HCC recurrence post DAAs, and whether those patients should be treated or not.

Surveillance Rate and its Impact on Survival of Hepatocellular Carcinoma Patients in South Korea: A Cohort Study

Purpose

Though regular surveillance of hepatocellular carcinoma (HCC) for high-risk patients is widely recommended, its rate and effectiveness are not clear. The aim of this study is to investigate the actual rate of HCC surveillance and its related factors and to clarify its impact on survival in a Korean HCC cohort.

Materials and Methods

From 2012 to 2015, 319 newly diagnosed HCC patients were prospectively enrolled at a tertiary hospital. Patient interviews based on a structured questionnaire survey were conducted. Surveillance was defined as liver imaging test ≥ 2 times with at least 3-month interval within 2 years prior to HCC diagnosis.

Results

Surveillance rate was 39.8%. Of the HCC patients with high-risk factors, only 182 (57.1%) had knowledge for the need for regular surveillance, and 141 (44.2%) had the accurate information about the method (ultrasound-based study). Surveillance group showed a higher proportion of early HCC (p < 0.001) and a longer overall survival (p < 0.001) compared to non-surveillance group. The multivariable Cox regression analysis indicated Child-Pugh class A, history of anti-viral therapy, low serum α-fetoprotein level, non-advanced Barcelona Clinic Liver Cancer stage as independent predictors of overall survival, while regular surveillance was not (p=0.436).

Conclusion

Less than half of the newly diagnosed Korean HCC patients were under surveillance and the accurate perception for the need of HCC surveillance was insufficient. Of those under surveillance, most patients were diagnosed with early stage HCC, which led to the improved survival. Comprehensive efforts to optimize the surveillance program for the target population are warranted.

Adherence to surveillance endoscopy following hospitalization for index esophageal variceal hemorrhage

AIM

To investigate patient adherence to surveillance endoscopy after index esophageal variceal hemorrhage and the extent to which adherence influences outcomes.

METHODS

We reviewed the records of patients with cirrhosis admitted to the medical intensive care unit between 2000 and 2014 for first time esophageal variceal hemorrhage treated with endoscopic variceal ligation who were subsequently discharged and scheduled for surveillance endoscopy at our medical center. Demographic and clinical data were obtained through the medical records, including etiology of cirrhosis, completion of variceal obliteration, attendance at surveillance endoscopy, zip code of primary residence, distance from home to hospital, insurance status, rehospitalization for variceal hemorrhage, beta-blocker at discharge, pharmacologically treated psychiatric disorder, and transplant free survival.

RESULTS

Of 99 consecutive survivors of esophageal variceal bleeding, the minority (33) completed variceal obliteration and fewer (12) adhered to annual surveillance. Completion of variceal obliteration was associated with fewer rehospitalizations for variceal rebleeding (27% vs 56%, P = 0.0099) and when rehospitalizations occurred, they occurred later in those who had completed obliteration (median 259 d vs 207 d, P = 0.0083). Incomplete adherence to endoscopic surveillance was associated with more rehospitalizations for variceal rebleeding compared to those fully adherent to annual endoscopic surveillance (51% vs 17%, P = 0.0328). Those adherent to annual surveillance were more likely to be insured privately or through Medicare compared to those who did not attend post-hospital discharge endoscopy (100% vs 63%, P = 0.0119).

CONCLUSION

Most patients do not complete variceal obliteration after index esophageal variceal hemorrhage and fewer adhere to endoscopic surveillance, particularly the uninsured and those insured with Medicaid.

Poor adherence to hepatocellular carcinoma surveillance: A systematic review and meta-analysis of a complex issue

BACKGROUND & AIMS

Hepatocellular carcinoma (HCC) surveillance is associated with improved outcomes and long-term survival. Our goal is to evaluate adherence rates to HCC surveillance.

METHODS

We performed a systematic search of the PubMed and Scopus databases and abstract search of relevant studies from recent major liver meetings. All searches and data extraction were performed independently by two authors. Analysis was via random-effects models and multivariate meta-regression.

RESULTS

A total of 22 studies (n = 19 511) met inclusion criteria (original non-interventional studies with defined cirrhosis or chronic hepatitis B or chronic hepatitis C with advanced fibrosis populations, and surveillance tests and intervals). Overall adherence rate was 52% (95% CI 38%-66%). Adherence was significantly higher in cirrhotic patients compared to chronic hepatitis B and other high-risk patients, in European compared to North American studies, in less than 12-month compared to yearly surveillance intervals, and in prospective compared to retrospective studies (71%, 95% CI 64%-78% vs 39%, 95% CI 26%-51%, P < .001). The between-study heterogeneity of all above analyses was significant (P < .001). Only the study design (retrospective vs prospective cohort) had statistical significance in a multivariate meta-regression model (P < .05) and could account for some of the differences above.

CONCLUSIONS

Overall adherence rate to HCC surveillance was suboptimal at 52% with no significant differences by liver disease aetiology or study location in multivariate meta-regression analysis. Further research and educational efforts are needed to improve the current rate of HCC surveillance.

Liver Transplantation for Alcoholic Liver Disease and Hepatocellular Carcinoma

Hepatocellular carcinoma is one of the main important causes of cancer-related death and its mortality is increasingly worldwide. In Europe, alcohol abuse accounts for approximately half of all liver cancer cases and it will become the leading cause of hepatocellular carcinoma in the next future with the sharp decline of chronic viral hepatitis. The pathophysiology of alcohol-induced carcinogenesis involves acetaldehyde catabolism, oxidative stress and chronic liver inflammation. Genetic background plays also a significant role and specific patterns of gene mutations in alcohol-related hepatocellular carcinoma have been characterized. Survival is higher in patients who undergo specific surveillance programmes than in patients who do not. However, patients with alcohol cirrhosis present a significantly greater risk of liver decompensation than those with cirrhosis due to other aetiologies. Furthermore, the adherence to screening program can be suboptimal. Liver transplant for patients with Milan-in hepatocellular carcinoma represents the best possible treatment in case of tumour recurrence/progression despite loco-regional or surgical treatments. Long-term result after liver transplantation for alcohol related liver disease is good. However, cardiovascular disease and de novo malignancies can significantly hamper patients' survival and should be carefully considered by transplant team. In this review, we have focused on the evolution of alcohol-related hepatocellular carcinoma epidemiology and risk factors as well as on liver transplantation in alcoholic patients with and without hepatocellular carcinoma.

Hepatocellular carcinoma risk following direct-acting antiviral HCV therapy: A systematic review, meta-analyses, and meta-regression

BACKGROUND & AIMS

The risk of hepatocellular carcinoma (HCC) occurrence or recurrence following direct-acting antiviral (DAA) hepatitis C virus (HCV) therapy remains unclear. The aims of this study were to compare the rate of HCC occurrence in patients with HCV-related cirrhosis, following DAA vs. interferon (IFN)-based cure, and to compare the rate of HCC recurrence in patients who received curative HCC treatment, following DAA vs. IFN-based cure.

METHODS

A search was conducted for reports published between January 2000 and February 2017. Studies were included if they assessed HCC outcomes by type and response to HCV therapy. Random-effects meta-analyses were undertaken to determine a combined estimate of HCC incidence rate per 100/person-years (py) among patients with a sustained virological response (SVR).

RESULTS

A total of 41 studies (n=13,875 patients), including 26 on HCC occurrence (IFN=17, DAA=9; prospective=19, retrospective=5, retrospective-prospective=2), and 17 on HCC recurrence (IFN=7, DAA=10; prospective=11, retrospective=5 and retrospective-prospective=1) were included. In studies assessing HCC occurrence, average follow-up was shorter (1.0 vs. 5.5years), and average age older (60 vs. 52years) in DAA studies. In studies assessing HCC recurrence, average follow-up was shorter (1.3 vs. 5.0years), but average age similar (64 vs. 66years) in DAA studies. HCC occurrence was 1.14/100 py (95% CI 0.86-1.52) and 2.96/100 py (95% CI 1.76-4.96) in IFN and DAA studies respectively. HCC recurrence was 9.21/100 py (95% CI 7.18-11.81) and 12.16/100 py (95% CI 5.00-29.58) in IFN and DAA studies respectively. In meta-regression adjusting for study follow-up and age, DAA therapy was not associated with higher HCC occurrence (RR 0.68; 95% CI 0.18-2.55; p=0.55) or recurrence (RR 0.62, 95% CI 0.11-3.45, p=0.56).

CONCLUSION

There is no evidence for differential HCC occurrence or recurrence risk following SVR from DAA and IFN-based therapy.

LAY SUMMARY

The risk of hepatocellular carcinoma (HCC) occurrence or recurrence following direct-acting antiviral (DAA) hepatitis C virus (HCV) therapy remains unclear. We conducted a meta-analysis to compare occurrence and recurrence of HCC in patients receiving either DAA or interferon (IFN) therapy. There is no evidence that HCC occurrence or recurrence is different between patients receiving DAA or IFN therapy.
