The role of routine biopsy of the background liver in the management of hepatocellular carcinoma

We sought to determine the influence of background liver biopsies on hepatocellular carci-noma (HCC) management. The pathology database at a large university hospital was searched between 2013 and 2018 for all instances of when a separate biopsy of the nontumoral liver was performed within 6 months of an HCC biopsy. Patients were evaluated for baseline demographic and clinical char-acteristics, treatment proposed prior to biopsy, and impact of biopsy results on management. Among the 104 identified cases of paired liver biopsies, 22% were women; the median age was 64 years; and most were of earlier HCC stages at diagnosis (Barcelona Clinic Liver Cancer stages 0-A: 70%). Four patients among 10 in whom cirrhosis status was clinically unclear were confirmed to have cirrhosis on biopsy, and 4 patients did not have cirrhosis despite clinical suspicion. Treatment was altered by the background parenchymal findings for 5 patients (5%): management was less aggressive for 4 patients and more aggressive for 1 patient. A background liver biopsy can significantly impact the management of a small subset of HCC patients, especially those with early disease, and should be considered concurrently with the biopsy of the mass.& COPY; 2023 Elsevier Inc.
