Evolutions in the Management of Hepatocellular Carcinoma over Last 4 Decades: An Analysis from the 100 Most Influential Articles in the Field

Abstract

<b><i>Introduction:</i></b> Over the past 4 decades, the management of hepatocellular carcinoma (HCC) has changed dramatically. The publications that have had the most significant impact on HCC management have not been quantitatively analyzed. In this article, we analyzed the 100 most influential articles over the past 4 decades using bibliometric citation analysis to characterize the evolution in HCC treatment. <b><i>Methods:</i></b> The top-cited publications were identified and analyzed from the Clarivate Analytics Web of Science Core Collection database. <b><i>Results:</i></b> The 100 most cited articles were identified with an average of 738 citations (range: 349–6,799). There was an increase in the number of influential articles in the late 1990s, which was paralleled by an increase in reports focused on locoregional treatment of HCC. Most top 100 articles came from the USA (<i>n</i> = 35), followed by Italy (<i>n</i> = 28), mainland China (<i>n</i> = 26), and Japan (<i>n</i> = 24). The surgical management was the most studied topic (<i>n</i> = 33). The <i>Annals of Surgery</i> published the highest number of papers (<i>n</i> = 26) with 13,978 citations. While other 3 topics (surgical management, locoregional treatment, and outcome prediction) declined among publications beginning in the 2000s, there was an emergence of highly cited papers on targeted drugs and immune checkpoint inhibitors with a concomitant increase in the number of publications on systemic therapy. <b><i>Conclusions:</i></b> Based on bibliometric analysis of the literature over the last 40 years, a comprehensive analysis of the most historically significant HCC management articles highlighted the key contributions made to the evolution and advancement of this specialist field. The data should provide clinicians and researchers insight into future directions relative to the advancement of HCC management.
