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. 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.
