Abstract

Hepatocellular carcinoma (HCC) is one of the most lethal malignant tumours worldwide. The mortality-to-incidence ratio is up to 91.6% in many countries, representing the third leading cause of cancer-related deaths. Systemic drugs, including the multikinase inhibitors sorafenib and lenvatinib, are first-line drugs used in HCC treatment. Unfortunately, these therapies are ineffective in most cases due to late diagnosis and the development of tumour resistance. Thus, novel pharmacological alternatives are urgently needed. For instance, immune checkpoint inhibitors have provided new approaches targeting cells of the immune system. Furthermore, monoclonal antibodies against programmed cell death-1 have shown benefits in HCC patients. In addition, drug combinations, including first-line treatment and immunotherapy, as well as drug repurposing, are promising novel therapeutic alternatives. Here, we review the current and novel pharmacological approaches to fight HCC. Preclinical studies, as well as approved and ongoing clinical trials for liver cancer treatment, are discussed. The pharmacological opportunities analysed here should lead to significant improvement in HCC therapy.

Core Tip: Hepatocellular carcinoma (HCC) is one of the most lethal malignant tumours worldwide. Unfortunately, most HCC cases are diagnosed at an advanced stage, and "curative" options are not suggested for these patients. The best option is to start with drug therapy, with sorafenib and lenvatinib as the first-choice drugs. However, most patients do not respond to these treatments; therefore, new therapeutic strategies are urgently needed. Here, we review current potential and novel pharmacological approaches, including immunotherapy, drug combination, and drug repositioning, that should help to improve the prognosis of HCC patients.
