This review explores the evolution of cancer staging, focusing on intermediate hepatocellular carcinoma (HCC), and the challenges faced by physicians. The Barcelona Clinic Liver Cancer (BCLC) staging system, introduced in 1999, was designed to address the limitations associated with providing accurate prognostic information for HCC and allocating specific treatments, to avoid overtreatment. However, criticism has emerged, particularly regarding the intermediate stage of HCC (BCLC-B) and its heterogeneous patient population. To overcome this limitation, various subclassification systems, such as the Bolondi and Kinki criteria, have been proposed. These systems are aimed at refining categorizations within the intermediate stage and have demonstrated varying degrees of success in predicting outcomes through external validation. This study discusses the shift in treatment paradigms, emphasizing the need for a more personalized approach rather than strictly adhering to cancer stages, without dismissing the relevance of staging systems. It assesses the available treatment options for intermediate-stage HCC, highlighting the importance of considering surgical and nonsurgical options alongside transarterial chemoembolization for optimal outcomes. In conclusion, the text advocates for a paradigm shift in staging systems prioritizing treatment suitability over cancer stage. This reflects the evolving landscape of HCC management, where a multidisciplinary approach is crucial for tailoring treatments to individual patients, ultimately aiming to improve overall survival.
