RESUMEN

BACKGROUND: The original hepatocellular carcinoma early detection screening (HES) score, which combines alpha-fetoprotein (AFP) with age, alanine aminotransferase, and platelets, has better performance than AFP alone for early HCC detection. We have developed HES V2.0 by adding AFP-L3 and des-gamma-carboxy prothrombin to the score and compared its performance to GALAD and ASAP scores among patients with cirrhosis. METHODS: We conducted a prospective-specimen collection, retrospective-blinded-evaluation phase 3 biomarker cohort study in patients with cirrhosis enrolled in imaging and AFP surveillance. True-positive rate (TPR)/sensitivity and false-positive rate for any or early HCC were calculated for GALAD, ASAP, and HES V2.0 scores within 6, 12, and 24 months of HCC diagnosis. We calculated the AUROC curve and estimated TPR based on an optimal threshold at a fixed false-positive rate of 10%. RESULTS: We analyzed 2331 patients, of whom 125 developed HCC (71% in the early stages). For any HCC, HES V2.0 had higher TPR than GALAD overall (+7.2%), at 6 months (+3.6%), at 12 months (+7.2%), and 24 months (+13.0%) before HCC diagnosis. HES V2.0 had higher TPR than ASAP for all time points (+5.9% to +12.0%). For early HCC, HES V2.0 had higher sensitivity/TPR than GALAD overall (+6.7%), at 12 months (+6.3%), and 24 months (+14.6%) but not at 6 months (+0.0%) and higher than ASAP for all time points (+13.4% to +18.0%). CONCLUSIONS: In a prospective cohort study, HES V2.0 had a significantly higher performance for identifying new HCC, including early stage, than GALAD or ASAP.

RESUMEN

BACKGROUND AND AIMS: Despite the substantial impact of environmental factors, individuals with a family history of liver cancer have an increased risk for HCC. However, genetic factors have not been studied systematically by genome-wide approaches in large numbers of individuals from European descent populations (EDP). APPROACH AND RESULTS: We conducted a 2-stage genome-wide association study (GWAS) on HCC not affected by HBV infections. A total of 1872 HCC cases and 2907 controls were included in the discovery stage, and 1200 HCC cases and 1832 controls in the validation. We analyzed the discovery and validation samples separately and then conducted a meta-analysis. All analyses were conducted in the presence and absence of HCV. The liability-scale heritability was 24.4% for overall HCC. Five regions with significant ORs (95% CI) were identified for nonviral HCC: 3p22.1, MOBP , rs9842969, (0.51, [0.40-0.65]); 5p15.33, TERT , rs2242652, (0.70, (0.62-0.79]); 19q13.11, TM6SF2 , rs58542926, (1.49, [1.29-1.72]); 19p13.11 MAU2 , rs58489806, (1.53, (1.33-1.75]); and 22q13.31, PNPLA3 , rs738409, (1.66, [1.51-1.83]). One region was identified for HCV-induced HCC: 6p21.31, human leukocyte antigen DQ beta 1, rs9275224, (0.79, [0.74-0.84]). A combination of homozygous variants of PNPLA3 and TERT showing a 6.5-fold higher risk for nonviral-related HCC compared to individuals lacking these genotypes. This observation suggests that gene-gene interactions may identify individuals at elevated risk for developing HCC. CONCLUSIONS: Our GWAS highlights novel genetic susceptibility of nonviral HCC among European descent populations from North America with substantial heritability. Selected genetic influences were observed for HCV-positive HCC. Our findings indicate the importance of genetic susceptibility to HCC development.

RESUMEN

BACKGROUND: Inflammatory and metabolic biomarkers have been associated with hepatocellular cancer (HCC) risk in phases I and II biomarker studies. We developed and internally validated a robust metabolic biomarker panel predictive of HCC in a longitudinal phase III study. METHODS: We used data and banked serum from a prospective cohort of 2266 adult patients with cirrhosis who were followed until the development of HCC (n=126). We custom designed a FirePlex immunoassay to measure baseline serum levels of 39 biomarkers and established a set of biomarkers with the highest discriminatory ability for HCC. We performed bootstrapping to evaluate the predictive performance using C-index and time-dependent area under the receiver operating characteristic curve (AUROC). We quantified the incremental predictive value of the biomarker panel when added to previously validated clinical models. RESULTS: We identified a nine-biomarker panel (P9) with a C-index of 0.67 (95% CI 0.66 to 0.67), including insulin growth factor-1, interleukin-10, transforming growth factor ß1, adipsin, fetuin-A, interleukin-1 ß, macrophage stimulating protein α chain, serum amyloid A and TNF-α. Adding P9 to our clinical model with 10 factors including AFP improved AUROC at 1 and 2 years by 4.8% and 2.7%, respectively. Adding P9 to aMAP score improved AUROC at 1 and 2 years by 14.2% and 7.6%, respectively. Adding AFP L-3 or DCP did not change the predictive ability of the P9 model. CONCLUSIONS: We identified a panel of nine serum biomarkers that is independently associated with developing HCC in cirrhosis and that improved the predictive ability of risk stratification models containing clinical factors.

RESUMEN

BACKGROUND & AIMS: Worldwide, hepatocellular carcinoma (HCC) is a common malignancy. We aimed to prospectively determine the incidence and risk factors of HCC in a U.S. METHODS: The multicenter Hepatocellular Carcinoma Early Detection Strategy study of the National Institutes of Health prospectively enrolled patients with cirrhosis who underwent standard surveillance for HCC. Demographics, medical and family history, etiology of liver disease, and clinical features were evaluated for associations with HCC. RESULTS: Between April 10, 2013 and December 31, 2021, 1723 patients were enrolled and confirmed eligible. During median follow-up of 2.2 years (range, 0-8.7 years), there were 109 incident cases of HCC for an incidence rate of 2.4 per 100 person-years: 88 (81%) patients with very early/early Barcelona Clinic Liver Cancer stage (0, A), 20 (18%) intermediate stage (B), and 1 (1%) unknown stage. Risk factor analyses were restricted to 1325 patients, including 95 incident HCC, with at least 6 months of follow-up. The majority were men (53.2%), obese or severely obese (median body mass index, 30.2 kg/m2), and white (86.3%); 42.0% had history of hepatitis C virus infection, 20.7% had alcoholic liver disease, and 24.9% had nonalcoholic fatty liver disease. Fourteen risk factors for HCC were significant (P < .05) in univariate analyses, and a multivariate subset was selected using stepwise logistic regression. The multivariate subset contained gender (P < .001; male; odds ratio [OR], 2.47; 95% confidence interval [CI], 1.54-4.07), years with cirrhosis (P = .004; OR, 1.06; 95% CI, 1.02-1.1), family history of liver cancer (P = .02; yes; OR, 2.69; 95% CI, 1.11-5.86), age (per 5 years; P = .02; OR, 1.17; 95% CI, 1.03-1.33), obesity (P = .02; yes; OR, 1.7; 95% CI, 1.08-2.73), aspartate aminotransferase (log(1+AST); P = .06; OR, 1.54; 95% CI, 0.97-2.42), alpha-fetoprotein (log(1+AFP); P = .07; OR, 1.32; 95% CI, 0.97-1.77), and albumin (P = .10; OR, 0.7; 95% CI, 0.46-1.07). CONCLUSIONS: Thus far, this is the largest prospective and geographically diverse study of a U.S. cohort of patients with cirrhosis that validates known risk factors for HCC (gender, age, obesity, years with cirrhosis, family history of liver cancer, baseline AFP, albumin, and AST). The incidence of HCC was 2.4% per 100 person-years.

RESUMEN

BACKGROUND AND AIMS: Etiological risk factors for cirrhosis have changed in the last decade. It remains unclear to what extent these trends in cirrhosis risk factors have changed HCC risk. APPROACH AND RESULTS: We used data from two contemporary, prospective multiethnic cohorts of patients with cirrhosis: the Texas Hepatocellular Carcinoma Consortium Cohort and the Houston Veterans Administration Cirrhosis Surveillance Cohort. Patients with cirrhosis were enrolled from seven US centers and followed until HCC diagnosis, transplant, death, or June 30, 2021. We calculated the annual incidence rates for HCC and examined the effects of etiology, demographic, clinical, and lifestyle factors on the risk of HCC. We included 2733 patients with cirrhosis (mean age 60.1 years, 31.3% women). At enrollment, 19.0% had active HCV, 23.3% had cured HCV, 16.1% had alcoholic liver disease, and 30.1% had NAFLD. During 7406 person-years of follow-up, 135 patients developed HCC at an annual incidence rate of 1.82% (95% CI, 1.51-2.13). The annual HCC incidence rate was 1.71% in patients with cured HCV, 1.32% in patients with alcoholic liver disease, and 1.24% in patients with NAFLD cirrhosis. Compared to patients with NAFLD, the risk of progression to HCC was 2-fold higher in patients with cured HCV (HR, 2.04; 95% CI, 1.24-3.35). Current smoking (HR, 1.63; 95% CI, 1.01-2.63) and overweight/obesity (HR, 1.79; 95% CI, 1.08-2.95) were also associated with HCC risk. CONCLUSIONS: HCC incidence among patients with cirrhosis was lower than previously reported. HCC risk was variable across etiologies, with higher risk in patients with HCV cirrhosis and lower risk in those with NAFLD cirrhosis. Current smoking and overweight/obesity increased HCC risk across etiologies.

RESUMEN

BACKGROUND & AIMS: The available risk stratification indices for hepatocellular cancer (HCC) have limited applicability. We developed and externally validated an HCC risk stratification index in U.S. cohorts of patients with cirrhosis. METHODS: We used data from 2 prospective U.S. cohorts to develop the risk index. Patients with cirrhosis were enrolled from 8 centers and followed until development of HCC, death, or December 31, 2021. We identified an optimal set of predictors with the highest discriminatory ability (C-index) for HCC. The predictors were refit using competing risk regression and its predictive performance was evaluated using the area under the receiver-operating characteristic curve (AUROC). External validation was performed in a cohort of 21,550 patients with cirrhosis seen in the U.S Veterans Affairs system between 2018 and 2019 with follow-up through 2021. RESULTS: We developed the model in 2431 patients (mean age 60 years, 31% women, 24% cured hepatitis C, 16% alcoholic liver disease, and 29% nonalcoholic fatty liver disease). The selected model had a C-index of 0.77 (95% confidence interval [CI], 0.73-0.81), and the predictors were age, sex, smoking, alcohol use, body mass index, etiology, α-fetoprotein, albumin, alanine aminotransferase, and platelet levels. The AUROCs were 0.75 (95% CI, 0.65-0.85) at 1 year and 0.77 (95% CI, 0.71-0.83) at 2 years, and the model was well calibrated. In the external validation cohort, the AUROC at 2 years was 0.70 with excellent calibration. CONCLUSION: The risk index, including objective and routinely available risk factors, can differentiate patients with cirrhosis who will develop HCC and help guide discussions regarding HCC surveillance and prevention. Future studies are needed for additional external validation and refinement of risk stratification.

RESUMEN

BACKGROUND & AIMS: There is a major unmet need to assess the prognostic impact of antifibrotics in clinical trials because of the slow rate of liver fibrosis progression. We aimed to develop a surrogate biomarker to predict future fibrosis progression. METHODS: A fibrosis progression signature (FPS) was defined to predict fibrosis progression within 5 years in patients with hepatitis C virus and nonalcoholic fatty liver disease (NAFLD) with no to minimal fibrosis at baseline (n = 421) and was validated in an independent NAFLD cohort (n = 78). The FPS was used to assess response to 13 candidate antifibrotics in organotypic ex vivo cultures of clinical fibrotic liver tissues (n = 78) and cenicriviroc in patients with nonalcoholic steatohepatitis enrolled in a clinical trial (n = 19, NCT02217475). A serum protein-based surrogate FPS was developed and tested in a cohort of compensated cirrhosis patients (n = 122). RESULTS: A 20-gene FPS was defined and validated in an independent NAFLD cohort (adjusted odds ratio, 10.93; area under the receiver operating characteristic curve, 0.86). Among computationally inferred fibrosis-driving FPS genes, BCL2 was confirmed as a potential pharmacologic target using clinical liver tissues. Systematic ex vivo evaluation of 13 candidate antifibrotics identified rational combination therapies based on epigallocatechin gallate, which were validated for enhanced antifibrotic effect in ex vivo culture of clinical liver tissues. In patients with nonalcoholic steatohepatitis treated with cenicriviroc, FPS modulation was associated with 1-year fibrosis improvement accompanied by suppression of the E2F pathway. Induction of the PPARα pathway was absent in patients without fibrosis improvement, suggesting a benefit of combining PPARα agonism to improve the antifibrotic efficacy of cenicriviroc. A 7-protein serum protein-based surrogate FPS was associated with the development of decompensation in cirrhosis patients. CONCLUSION: The FPS predicts long-term fibrosis progression in an etiology-agnostic manner, which can inform antifibrotic drug development.

RESUMEN

BACKGROUND AND AIMS: Most patients with HCC are diagnosed at a late stage, highlighting the need for more accurate surveillance tests. Although biomarkers for HCC early detection have promising data in Phase 2 case-control studies, evaluation in cohort studies is critical prior to adoption in practice. We leveraged a prospective cohort of patients with Child-Pugh A or B cirrhosis who were followed until incident HCC, liver transplantation, death, or loss to follow-up. We used a prospective specimen collection, retrospective, blinded evaluation design for biomarker evaluation of GALAD (gender × age × log alpha-fetoprotein [AFP] × des-gamma-carboxy prothrombin), longitudinal GALAD, and the HCC Early Detection Screening (HES) algorithm-compared to AFP-using patient-level sensitivity and screening-level specificity. APPROACH AND RESULTS: Of 397 patients with cirrhosis, 42 developed HCC (57.1% early stage) over a median of 2.0 years. Longitudinal GALAD had the highest c-statistic for HCC detection (0.85; 95% CI, 0.77-0.92) compared to single-time point GALAD (0.79; 95% CI, 0.71-0.87), AFP (0.77; 95% CI, 0.69-0.85), and HES (0.76; 95% CI, 0.67-0.83). When specificity was fixed at 90%, the sensitivity for HCC of single-time point and longitudinal GALAD was 54.8% and 66.7%, respectively, compared to 40.5% for AFP. Sensitivity for HCC detection was higher when restricted to patients with biomarker assessment within 6 months prior to HCC diagnosis, with the highest sensitivities observed for single-time point GALAD (72.0%) and longitudinal GALAD (64.0%), respectively. Sensitivity of single-time point and longitudinal GALAD for early-stage HCC was 53.8% and 69.2%, respectively. CONCLUSION: GALAD demonstrated high sensitivity for HCC detection in a cohort of patients with cirrhosis. Validation of these results is warranted in large Phase 3 data sets.

RESUMEN

BACKGROUND & AIMS: There is controversy regarding the overall value of hepatocellular carcinoma (HCC) surveillance in patients with cirrhosis given the lack of data from randomized-controlled trials. To address this issue, we conducted a systematic review and meta-analysis of cohort studies evaluating the benefits and harms of HCC surveillance in patients with cirrhosis. METHODS: We performed a search of the Medline and EMBASE databases and national meeting abstracts from January 2014 through July 2020 for studies reporting early-stage HCC detection, curative treatment receipt, or overall survival, stratified by HCC surveillance status, among patients with cirrhosis. Pooled risk ratios (RRs) and hazard ratios, according to HCC surveillance status, were calculated for each outcome using the DerSimonian and Laird method for random effects models. RESULTS: We identified 59 studies including 145,396 patients with HCC, which was detected by surveillance in 41,052 (28.2%) cases. HCC surveillance was associated with improved early-stage detection (RR 1.86, 95% CI 1.73-1.98; I2 = 82%), curative treatment receipt (RR 1.83, 95% CI 1.69-1.97; I2 = 75%), and overall survival (hazard ratio 0.67, 95% CI 0.61-0.72; I2 = 78%) after adjusting for lead-time bias; however, there was notable heterogeneity in all pooled estimates. Four studies examined surveillance-related physical harms due to false positive or indeterminate surveillance results, but no studies examined potential financial or psychological harms. The proportion of patients experiencing surveillance-related physical harms ranged from 8.8% to 27.5% across studies, although most harms were mild in severity. CONCLUSION: HCC surveillance is associated with improved early detection, curative treatment receipt, and survival in patients with cirrhosis, although there was heterogeneity in pooled estimates. Available data suggest HCC surveillance is of high value in patients with cirrhosis, although continued rigorous studies evaluating benefits and harms are still needed. LAY SUMMARY: There has been ongoing debate about the overall value of hepatocellular carcinoma (HCC) screening in patients with cirrhosis given the lack of data from randomized-controlled trials. In a systematic review of contemporary cohort studies, we found that HCC screening is associated with improved early detection, curative treatment receipt, and survival in patients with cirrhosis, although there were fewer data quantifying potential screening-related harms. Available data suggest HCC screening is of high value in patients with cirrhosis, although continued studies evaluating benefits and harms are still needed.

RESUMEN

Hepatocellular carcinoma (HCC) surveillance is associated with early tumor detection and improved survival in patients with cirrhosis.1 Surveillance is performed using semiannual abdominal ultrasound with or without α-fetoprotein (AFP); however, this strategy misses more than one-third of HCC at an early stage.2 These data highlight a need for novel surveillance strategies with higher accuracy for early HCC detection. GALAD and Doylestown Plus are novel biomarker panels that combine multiple biomarkers with patient demographic and clinical characteristics; both demonstrated promising accuracy in phase II case-control studies;3,4 however, case-control studies can overestimate biomarker performance, highlighting a need for phase III cohort and nested case-control studies.5 Our study aimed to compare multiple biomarkers (including AFP, GALAD, and Doylestown Plus) in a nested case-control study of patients with cirrhosis.

RESUMEN

BACKGROUND AND AIMS: Hepatocellular carcinoma (HCC) is the fastest rising cause of cancer-related death in the United States; however, HCC incidence and mortality are not equally distributed among racial and ethnic groups. Our aim was to characterize the direction and magnitude of racial and ethnic disparities in overall survival and early tumor detection among patients with HCC. METHODS: We searched MEDLINE, EMBASE and Cochrane databases from inception through August 2020 for studies reporting HCC outcomes (early stage presentation and overall survival) by race and ethnicity. We calculated pooled hazard ratios (HRs) and odds ratios (ORs) for each racial and ethnic group (White, Black, Hispanic, Asian) using the DerSimonian and Laird method for a random-effects model. RESULTS: We identified 35 articles comprising 563,097 patients (53.0% White, 17.3% Black, 18.4% Hispanic, 5.0% Asian). Compared with White patients, Black patients had worse survival (pooled HR 1.08; 95% CI, 1.05 - 1.12), whereas Hispanic (pooled HR 0.92; 95% CI, 0.87 - 0.97) and Asian (pooled HR 0.81; 95% CI, 0.73 - 0.88) patients had better survival. Among articles reporting tumor stage (n = 20), Black patients had lower odds of early stage HCC compared with White patients (OR, 0.66; 95% CI, 0.54 - 0.78). Conversely, there was no difference in odds of early HCC detection for Asian (OR, 1.01; 95% CI, 0.97 - 1.05) or Hispanic patients (OR, 0.87; 95% CI, 0.74 - 1.01) compared with White patients. The most common limitation of studies was risk of residual confounding from socioeconomic status and liver dysfunction. CONCLUSIONS: There are significant racial and ethnic disparities in HCC prognosis in the United States, with Black patients having worse overall survival and Hispanic and Asian patients having better overall survival compared with White patients. Interventions are needed to reduce disparities in early HCC detection to improve HCC prognosis.

RESUMEN

Cirrhosis is the terminal stage of progressive liver fibrosis, affecting 1%-2% of the global population and accounting for 1.3 million deaths annually.1,2 Median survival for persons with compensated cirrhosis is approximately 12 years, compared with only 2 years for those with hepatic decompensation. Accurate prediction of hepatic decompensation is an unmet need to enable identification of patients with cirrhosis who could benefit from close monitoring and timely medical interventions. Besides, risk stratification of patients with cirrhosis could help inform patient selection for trials evaluating therapies to prevent hepatic decompensation. Although various clinical scores, such as the albumin-bilirubin (ALBI) and fibrosis-4 (FIB-4) indices (ALBI-FIB4 score) have been proposed to predict long-term risk of hepatic decompensation,3 external validation has often shown suboptimal prognostic capability and revealed room for improvement.4.

RESUMEN

BACKGROUND & AIMS: Cancer cachexia is a wasting syndrome associated with functional impairment and reduced survival that impacts up to 50% of patients with gastrointestinal cancers. However, data are limited on the prevalence and clinical significance of cachexia in patients with hepatocellular carcinoma (HCC). METHODS: We performed a retrospective cohort study of patients diagnosed with HCC at 2 United States health systems between 2008 and 2018. Patient weights were recorded 6 months prior to and at time of HCC diagnosis. Cachexia was defined as >5% weight loss (or >2% weight loss if body mass index <20 kg/m2), and precachexia was defined as 2% to 5% weight loss. We used multivariable logistic regression models to identify correlates of cachexia and multivariable Cox proportional hazard models to identify factors associated with overall survival. RESULTS: Of 604 patients with HCC, 201 (33.3%) had precachexia and 143 (23.7%) had cachexia at diagnosis, including 19.0%, 23.5%, 34.7%, and 34.0% of patients with Barcelona Clinic Liver Cancer stages 0/A, B, C, and D, respectively. Patients with cachexia were less likely to receive HCC treatment (odds ratio, 0.38; 95% confidence interval, 0.21-0.71) and had worse survival than those with precachexia or stable weight (11.3 vs 20.4 vs 23.5 months, respectively; P < .001). Cachexia remained independently associated with worse survival (hazard ratio, 1.43; 95% confidence interval, 1.11-1.84) after adjusting for age, sex, race, ethnicity, Child Pugh class, alpha-fetoprotein, Barcelona Clinic Liver Cancer stage, and HCC treatment. CONCLUSIONS: Nearly 1 in 4 patients with HCC present with cachexia, including many with compensated cirrhosis or early stage tumors. The presence of cancer-associated weight loss appears to be an early and independent predictor of worse outcomes in patients with HCC.

RESUMEN

BACKGROUND & AIMS: Identifying patients in whom ultrasound may be inadequate to exclude the presence of hepatocellular carcinoma (HCC) can inform interventions to improve screening effectiveness. We aimed to characterize correlates of suboptimal ultrasound quality and changes in ultrasound quality over time in patients with cirrhosis undergoing HCC screening. METHODS: We performed a retrospective cohort study of patients with cirrhosis who underwent ultrasound examination at 2 large health systems between July 2016 and July 2019. Exam adequacy was graded by radiologists using the LI-RADS Visualization Score (A, B, C); we evaluated changes in visualization over time among patients with >1 ultrasound exams. We performed multivariable logistic regression to identify characteristics associated with limited ultrasound visualization (scores B or C). RESULTS: Of 2053 cirrhosis patients, 1685 (82.1%) had ultrasounds with score A, 262 (12.8%) had score B, and 106 (5.2%) had score C. Limited visualization was associated with alcohol-related or nonalcoholic fatty liver disease cirrhosis and presence of class II-III obesity. Among 1546 patients with >1 ultrasounds, 1129 (73.0%) had the same visualization score on follow-up (1046 score A, 60 score B, 23 score C). However, 255 (19.6%) of 1301 with score A at baseline had limited visualization when repeated (230 score B, 25 score C), and 130 (53.1%) of 245 patients with baseline limited visualization had good visualization when repeated. CONCLUSIONS: Nearly 1 in 5 patients with cirrhosis had moderately-severely limited ultrasound visualization for HCC nodules, particularly those with obesity or alcohol-related or nonalcoholic fatty liver disease cirrhosis. Ultrasound quality can change between exams, including improvement in many patients with limited visualization.

RESUMEN

Patients with indeterminate liver nodules, classified as LR-3 and LR-4 observations per the Liver Imaging Reporting and Data System, are at risk of developing hepatocellular carcinoma (HCC), but risk estimates remain imprecise. We conducted a systematic review of Ovid MEDLINE, EMBASE, and Cochrane databases from inception to December 2021 to identify cohort studies examining HCC incidence among patients with LR-3 or LR-4 observations on computed tomography (CT) or magnetic resonance imaging (MRI). Predictors of HCC were abstracted from each study, when available. Of 13 total studies, nine conducted LR-3 observation-level analyses, with the proportions of incident HCC ranging from 1.2% to 12.5% at 12 months and 4.2% to 44.4% during longer study follow-up. Among three studies with patient-level analyses, 8%-22.2% of patients with LR-3 lesions developed LR-4 observations and 11.1%-24.5% developed HCC. Among nine studies conducting LR-4 observation-level analyses, incident HCC ranged from 30.8% to 44.0% at 12 months and 30.9% to 71.0% during study follow-up; conversely, 6%-42% of observations were downgraded to LR-3 or lower. Patient-level factors associated with HCC included older age, male sex, higher alpha-fetoprotein levels, viral etiology, and prior history of HCC; observation-level factors included maximum diameter, threshold growth, T2 hyperintensity, and visibility on ultrasound. Studies were limited by small sample sizes, inclusion of patients with prior HCC, short follow-up duration, and failure to account for clustering of observations in patients or competing risks of transplantation and death. LR-3 and LR-4 observations have elevated but variable risks of HCC. Higher quality studies are necessary to identify high-risk patients who warrant close CT or MRI-based follow-up.

RESUMEN

Survivorship after liver transplantation (LT) is a novel concept providing a holistic view of the arduous recovery experienced after transplantation. We explored components of early survivorship including physical, emotional, and psychological challenges to identify intervention targets for improving the recovery process of LT recipients and caregivers. A total of 20 in-person interviews were conducted among adults 3 to 6 months after LT. Trained qualitative research experts conducted interviews, coded, and analyzed transcripts to identify relevant themes and representative quotes. Early survivorship comprises overcoming (1) physical challenges, with the most challenging experiences involving mobility, driving, dietary modifications, and medication adherence, and (2) emotional and psychological challenges, including new health concerns, financial worries, body image/identity struggles, social isolation, dependency issues, and concerns about never returning to normal. Etiology of liver disease informed survivorship experiences including some patients with hepatocellular carcinoma expressing decisional regret or uncertainty in light of their post-LT experiences. Important topics were identified that framed LT recovery including setting expectations about waitlist experiences, hospital recovery, and ongoing medication requirements. Early survivorship after LT within the first 6 months involves a wide array of physical, emotional, and psychological challenges. Patients and caregivers identified what they wish they had known prior to LT and strategies for recovery, which can inform targeted LT survivorship interventions.

RESUMEN

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.

RESUMEN

BACKGROUND: The neutrophil-lymphocyte ratio (NLR) has been proposed as a prognostic biomarker for cirrhosis and non-liver malignancies. We aimed to evaluate the prognostic value of NLR in a diverse cohort of patients with hepatocellular carcinoma (HCC). METHODS: We performed a retrospective study of patients diagnosed with HCC between 2008 and 2017 at two large US health systems. We used Cox proportional hazard and multivariable ordinal logistic regression models to identify factors associated with overall survival and response to first HCC treatment, respectively. Primary variables of interest were baseline NLR and delta NLR, defined as the difference between pre- and post-treatment NLR. RESULTS: Among 1019 HCC patients, baseline NLR was < 5 in 815 (80.0%) and ≥ 5 in 204 (20.0%). Patients with NLR ≥ 5 had a higher proportion of infiltrative tumors (36.2% vs 22.3%), macrovascular invasion (39.6% vs 25.5%), metastatic disease (20.6% vs 11.4%), and AFP > 200 ng/mL (45.6% vs 33.8%). Baseline NLR ≥ 5 was independently associated with higher mortality (median survival 4.3 vs 15.1 months; adjusted HR 1.70, 95%CI 1.41-2.06), with differences in survival consistent across BCLC stages. After adjusting for baseline covariates including NLR, delta NLR > 0.26 was also independently associated with increased mortality (HR 1.42, 95%CI 1.14-1.78). In a secondary analysis, high NLR was associated with lower odds of response to HCC treatment (20.2% vs 31.6%; adjusted OR 0.55, 95%CI 0.32-0.95). CONCLUSIONS: In a large Western cohort of patients with HCC, high baseline NLR and delta NLR were independent predictors of mortality. IMPACT: NLR is an inexpensive test that may be a useful component of future HCC prognostic models.

RESUMEN

BACKGROUND & AIMS: The value of a cancer screening programs is defined by its balance of benefits and harms; however, there are few data evaluating both attributes for hepatocellular carcinoma (HCC) surveillance. We aimed to characterize benefits and harms of HCC surveillance in a large prospective cohort of patients with cirrhosis. METHODS: We conducted a secondary analysis of a clinical trial evaluating HCC surveillance among patients with cirrhosis at a safety-net health system enrolled between December 2014 and July 2015. We quantified surveillance-related benefits, defined as early HCC detection and curative treatment receipt, and physical harms, defined as diagnostic procedures for false positive or indeterminate results, over an 18-month period. RESULTS: Of 614 cirrhosis patients with ≥1 surveillance exam, abnormal results were observed in 118 (19.2%) patients. Twenty-six patients developed HCC during follow-up, of whom 16 (61.5%) were detected by surveillance. The proportion of HCC detected at BCLC stage 0/A (62.5% vs 50%, p = .69) and who underwent curative treatment (43.8% vs. 40.0%, p = 1.0) did not significantly differ between surveillance-detected patients and those diagnosed incidentally/symptomatically. Physical harms were observed in 54 (8.8%) patients who underwent surveillance - most of mild severity with only 1 diagnostic CT or MRI and none undergoing invasive testing such as biopsy. Incidental findings on follow-up imaging were found in 40 (6.5%) patients -23 of low clinical importance and 17 medium clinical importance. CONCLUSIONS: In our cohort of patients with cirrhosis, HCC surveillance was associated with high early tumor detection and minimal physical harms.

RESUMEN

Survivorship is a well-established concept in the cancer care continuum with a focus on disease recurrence, quality of life, and the minimization of competing risks for mortality; however, survivorship has not been well studied in liver transplantation (LT). We investigated what survivorship means to LT patients and identified motivations and coping strategies for overcoming challenges after LT. A total of 20 in-depth home interviews were conducted among adults 3 to 6 months after LT. Interviews were conducted by trained qualitative research experts and coded and analyzed using an inductive approach. A majority of LT recipients (75%) identified themselves as survivors. Integral to the definition of survivorship was overcoming hardship (including experiences on the waiting list) and the unique experience of being given a "second chance" at life. Motivations to survive included a new chance at life (55%), family (40%), spirituality/faith (30%), and fear of rejection (15%). LT recipients and caregivers identified multiple strategies to cope with post-LT challenges, including relying on a large network of community, spiritual, and virtual support. These findings informed a conceptual model of LT survivorship based on socioecological theory, which identified the following variables influencing survivorship: (1) pretransplant experiences, (2) individual attributes and challenges, (3) interpersonal relationships with caregivers and other social support, (4) community relationships, and (5) large-scale factors including neighborhood and financial issues. LT recipients identified themselves as survivors, and post-LT identities were greatly influenced by pre-LT experiences. These perspectives informed an in-depth conceptual model of survivorship after transplantation. We identified sources of motivation and coping strategies used in LT recovery that could be targets of survivorship interventions aimed at improving post-LT outcomes.
