INTRODUCTION AND OBJECTIVES Failures at any step in the hepatocellular carcinoma (HCC) surveillance process can result in HCC diagnostic delays and associated worse prognosis. We aimed to estimate the prevalence of surveillance failure and its associated risk factors in patients with HCC in Argentina, considering three steps: 1) recognition of at-risk patients, 2) implementation of HCC surveillance, 3) success of HCC surveillance. METHODS We performed a multi-center cross-sectional study of patients at-risk for HCC in Argentina seen between10.01.2018 and 10.30.2019. Multivariable logistic regression analysis was used to identify correlates of surveillance failure. RESULTS Of 301 included patients, the majority were male (74.8%) with a mean age of 64 years old. At the time of HCC diagnosis, 75 (24.9%) patients were unaware of their diagnosis of chronic liver disease, and only 130 (43.2%) patients were under HCC surveillance. Receipt of HCC surveillance was significantly associated with follow-up by a hepatologist. Of 119 patients with complete surveillance, surveillance failure occurred in 30 (25.2%) patients. Surveillance failure was significantly associated with alpha fetoprotein ≥20 ng/ml (OR 4.0, CI 95% 1.43-11.55). CONCLUSIONS HCC surveillance failure was frequent in all the evaluated steps. These data should help guide strategies to improve the implementation and results of HCC surveillance in our country.
