Controversies in staging of hepatocellular carcinoma.
Hepatocellular carcinoma (HCC) is the most common primary cancer of the liver. As the natural history of HCC is better delineated, treatment strategies are in constant evolution. Classic staging systems based on histopathology following resection are often inadequate because the majority of patients present with advanced disease. The dissatisfaction with anatomic staging systems has resulted in the emergence of several new clinical staging systems, which attempt to integrate tumor biology and the underlying function of the nondiseased liver. Tragically, the byproduct of multiple staging strategies is confusion for physicians, patients, and clinical researchers; this undermines the principles on which staging systems are created. To address this issue, a consensus conference was organized in 2002 to identify the best staging strategy for HCC. The purpose of this article is to review the current clinical and pathologic staging strategies and to highlight the recommendations from the consensus conference.
