Abstract:

BACKGROUND: The value of hepatocellular carcinoma (HCC) screening is defined by the balance of benefits from early tumor detection vs harms due to false positive results. We evaluated the value of a mailed outreach strategy for HCC screening in patients with cirrhosis. METHODS: We conducted a multi-center pragmatic randomized clinical trial comparing mailed outreach for HCC screening (n = 1436) and usual care with visit-based screening (n = 1436) among patients with cirrhosis at three health systems from March 2018 to September 2021. Outcomes of interest were early-stage HCC detection (ie, screening benefit) and diagnostic evaluation for false positive or indeterminate results (ie, screening harm). Screening harm was categorized as mild, moderate, and severe based on number and type of diagnostic exams. All patients were included in intention-to-screen analyses. RESULTS: Of 125 patients diagnosed with HCC (67 outreach and 58 usual care), 71.2% were found at an early stage per the Milan Criteria. Early tumor detection did not significantly differ between the outreach and usual care arms (64.2% vs 79.3%, p = .06). The proportion of patients with physical harms also did not differ between the outreach and usual care arms (10.8% vs 10.7%, p = .95) with 5.9% in both arms having mild harms, 4.0% and 3.8% respectively with moderate harms, and 0.9% and 1.0% respectively with severe harms. CONCLUSION: Most patients enrolled in HCC screening were detected at an early stage, and a minority experienced physical harms. A mailed outreach strategy did not significantly increase early HCC detection or physical harms compared to usual care. CLINICAL TRIALS NUMBER: NCT02582918 and NCT03756051.
