Evaluation of Ultrasound-based Surveillance for Hepatocellular Carcinoma in Patients at Risk: Results From a German Multicenter Retrospective Cohort Study.

ABSTRACT:

Background and aims

Hepatocellular carcinoma (HCC) surveillance in patients at risk is strongly recommended and usually performed by ultrasound (US) semiannually with or without alfa-fetoprotein (AFP) measurements. Quality parameters except for surveillance intervals have not been strictly defined. We aimed to evaluate surveillance success and risk factors for surveillance failure.

Methods

Patients with ≥1 US prior to HCC diagnosis performed at four tertiary referral hospitals in Germany between 2008 and 2019 were retrospectively analyzed. Surveillance success was defined as HCC detection within Milan criteria.

Results

Only 47% of 156 patients, median age 63 (interquartile range: 57-70) years, 56% male, and 96% with cirrhosis, received recommended surveillance modality and interval. Surveillance failure occurred in 29% and was significantly associated with lower median model for end-stage liver disease (MELD) score odds ratio (OR) 1.154, 95% confidence interval (CI): 1.027-1.297, p=0.025) and HCC localization within right liver lobe (OR: 6.083, 95% CI: 1.303-28.407, p=0.022), but not with AFP ≥200 µg/L. Patients with surveillance failure had significantly more intermediate/advanced tumor stages (93% vs. 6%, p<0.001), fewer curative treatment options (15% vs. 75%, p<0.001) and lower survival at 1 year (54% vs. 75%, p=0.041), 2 years (32% vs. 57%, p=0.019) and 5 years (0% vs. 16%, p=0.009). Alcoholic and non-alcoholic fatty liver disease (OR: 6.1, 95% CI: 1.7-21.3, p=0.005) and ascites (OR: 3.9, 95% CI: 1.2-12.6, p=0.021) were independently associated with severe visual limitations on US.

Conclusions

US-based HCC surveillance in patients at risk frequently fails and its failure is associated with unfavorable patient-related outcomes. Lower MELD score and HCC localization within right liver lobe were significantly associated with surveillance failure.

Project description:ImportanceHepatocellular carcinoma (HCC) surveillance is underused in clinical practice, which may be owing to patient and clinician barriers.ObjectiveTo characterize HCC surveillance barriers and associations with clinical outcomes in a multicenter cohort of patients with cirrhosis.Design, setting, and participantsThis retrospective, multicenter cohort study included 5 medical centers in the United States. Patients with cirrhosis and newly diagnosed HCC treated from 2014 to 2018 were included. Data were analyzed from June 2021 to February 2022.ExposureSurveillance completion in the 36-month period prior to HCC diagnosis.Main outcomes and measuresSurveillance receipt was classified as semiannual, annual, or no surveillance. Multivariable logistic regression analysis was used to identify factors associated with semiannual surveillance. We conducted multivariable logistic and Cox regression analyses to characterize associations between surveillance completion with curative treatment and overall survival.ResultsA total 629 eligible patients (median [IQR] age, 63.6 [56.2-71.0] years; 491 [78.1%] men) were assessed, including 7 American Indian or Alaska Native patients (1.1%), 14 Asian patients (2.2), 176 Black patients (28.0%), 86 Hispanic patients (13.1%), and 340 White patients (54.1%). Nearly two-thirds of the cohort had no surveillance prior to HCC diagnosis (mean [range by site] 63.7% [37.9%-80.4%]), with a mean (range by site) of 14.0% (5.3%-33.3%) of patients having received semiannual surveillance and 22.3% (14.3%-28.8%) of patients having received annual surveillance. The most common reasons for no surveillance were lack of surveillance orders or nonadherence (mean [range by site], 82.4% [66.7%-92.4%], although a mean (range by site) of 17.6% (10.2%-22.1%) of patients had unrecognized cirrhosis at HCC presentation. Semiannual surveillance was associated with hepatitis B infection (odds ratio [OR], 3.06 [95% CI, 1.24-7.23]) and inversely associated with Black race (OR, 0.41 [95% CI, 0.20-0.80]) and lack of cirrhosis recognition (OR, 0.14 [95% CI, 0.02-0.46]). Semiannual HCC surveillance was significantly associated with curative treatment receipt (OR, 2.73 [95% CI, 1.60-4.70]) but not overall survival (HR, 0.81 [95% CI, 0.55-1.18]).Conclusions and relevanceIn this cohort study of patients with cirrhosis, HCC surveillance was underused in more than 80% of patients and associated with failures across the screening process. Dedicated programs to improve cirrhosis detection and HCC surveillance attainment are needed.

Project description:The optimal schedule for ultrasonographic surveillance of patients with viral hepatitis for the detection of hepatocellular carcinoma (HCC) remains unclear owing to a lack of reliable studies. We examined the timing of ultrasonography in patients with viral hepatitis-induced HCC and its impact on survival and mortality risk while determining predictors of receiving surveillance before HCC diagnosis. A population-based retrospective cohort analysis of patients with viral hepatitis-induced HCC in Ontario between 2000 and 2010 was performed using data from the Ontario Cancer Registry linked health administrative data. HCC surveillance for 2 years preceding diagnosis was assigned as: i) ≥ 2 abdominal ultrasound screens annually; ii) 1 screen annually; iii) inconsistent screening; and iv) no screening. Survival rates were estimated using the Kaplan-Meier method and parametric models to correct for lead-time bias. Associations between HCC surveillance and the risk of mortality after diagnosis were examined using proportional-hazards regression adjusting for confounding factors. Overall, 1,483 patients with viral hepatitis-induced HCC were identified during the study period; 20.2% received ≥ 1 ultrasound screen annually (routine surveillance) for the 2 years preceding diagnosis. The 5-year survival of those receiving routine surveillance was 31.93% (95% CI: 25.77-38.24%) and 31.84% (95% CI: 25.69-38.14%) when corrected for lead-time bias (HCC sojourn time 70 days and 140 days, respectively). This is contrasted with 20.67% (95% CI: 16.86-24.74%) 5-year survival in those who did not undergo screening. In the fully adjusted model, compared to unscreened patients, routine surveillance was associated with a lower mortality risk and a hazard ratio of 0.76 (95% CI: 0.64-0.91) and 0.81 (95% CI: 0.68-0.97), corrected for the respective lead-time bias. Our findings suggest that routine ultrasonography in patients with viral hepatitis is associated with improved survival and reduced mortality risk in a population-based setting. The data emphasizes the importance of surveillance for timely intervention in HCC-diagnosed patients.

Project description:BackgroundMore than 20% of patients with cirrhosis do not receive semi-annual hepatocellular carcinoma (HCC) surveillance as recommended. Few studies have evaluated the effects of patient-level factors on surveillance receipt.MethodsWe administered a telephone survey to a large cohort of patients with cirrhosis from 3 health systems (a tertiary care referral center, a safety-net health system, and Veterans Affairs) to characterize patient knowledge, attitudes, and perceived barriers of HCC surveillance. Multinomial logistic regression was performed to identify factors associated with HCC surveillance receipt (semi-annual and annual vs none) during the 12-month period preceding survey administration.ResultsOf 2871 patients approached, 1020 (35.5%) completed the survey. Patients had high levels of concern about developing HCC and high levels of knowledge about HCC. However, patients had knowledge deficits, including believing surveillance was unnecessary when physical examination and laboratory results were normal. Nearly half of patients reported barriers to surveillance, including costs (28.9%), difficulty scheduling (24.1%), and transportation (17.8%). In the year before the survey, 745 patients (73.1%) received 1 or more surveillance examination; 281 received on-schedule, semi-annual surveillance and 464 received annual surveillance. Semi-annual HCC surveillance (vs none) was significantly associated with receipt of hepatology subspecialty care (odds ratio, 30.1; 95% CI, 17.5-51.8) and inversely associated with patient-reported barriers (odds ratio, 0.62; 95% CI, 0.41-0.94). Patterns of associations comparing annual vs no surveillance were similar although the magnitude of effects were reduced.ConclusionsPatient-reported barriers such as knowledge deficits, costs, difficulty scheduling, and transportation are significantly associated with less frequent receipt of HCC surveillance, indicating a need for patient-centered interventions, such as patient navigation.

Project description:Ultrasound-based surveillance has suboptimal sensitivity for early detection of hepatocellular carcinoma (HCC) in patients with cirrhosis. There are several emerging alternatives, including a novel multitarget HCC blood test (Mt-HBT). We compared performance of mt-HBT against ultrasound with or without alpha-fetoprotein (AFP) for early HCC detection in patients with cirrhosis. Per the Preferred Reporting Items for Systematic Reviews and Meta-Analysis (PRISMA) guidelines, two reviewers searched PubMed, Cochrane, Embase, and clinicaltrials.gov databases from January 1990 through December 2020 to identify studies reporting sensitivity and/or specificity of ultrasound and AFP for overall and early stage HCC detection in patients with cirrhosis. Mt-HBT diagnostic performance was derived from a clinical validation study. A network meta-analysis model was built for comparative assessment, and pooled estimates of sensitivity at a fixed specificity were estimated based on Bayesian binormal receiver operating characteristic models for each modality. Forty-one studies (comprising 62,517 patients with cirrhosis) met inclusion criteria. Ultrasound-alone sensitivity was 51.6% (95% credible interval [CrI], 43.3%-60.5%) for early stage HCC detection, which increased with the addition of AFP to 74.1% (95% CrI, 62.6%-82.4%); however, this was offset by decreased specificity (87.9% vs. 83.9%, respectively). With specificity fixed at 90%, mt-HBT sensitivity for early stage HCC detection was higher than ultrasound alone (18.2%; 95% CrI, 0.2%-37.7%) and similar to ultrasound with AFP (-3.3%; 95% CrI, -22.3%-17.4%). Pairwise posterior probabilities suggested a preference for mt-HBT over ultrasound alone in 97.4% of cases but only 36.3% of cases versus ultrasound with AFP. Conclusion: A blood-based mt-HBT has higher sensitivity than ultrasound alone for early stage HCC detection but similar sensitivity compared to ultrasound and AFP. Mt-HBT could be a comparable alternative to existing methods for HCC surveillance in patients who are at risk.
