Introduction:
Although hepatocellular carcinoma (HCC) is the most frequent primary liver cancer, there are limited therapeutic options for the advanced stages. Sorafenib was the first tyrosine-kinase inhibitor (TKI) approved for unresectable HCC and remained the only effective choice for a decade. The horizon of systemic treatments drastically expanded in the latest years, opening new interesting possibilities.
Areas Covered:
In this manuscript, the authors have analysed the recent advances in pharmacotherapy for HCC, discussing their mechanisms of action, the clinical efficacy and the safety profile of currently available first, second-and third-line treatments. The authors have also analysed the role of immune system modulators, in particular immune checkpoints inhibitors (ICIs), based on the limited data published so far.
Expert Opinion:
The emergence of new targeted therapies, such as lenvatinib, have changed the landscape of HCC therapy. Tumor extension, differences in objective response rates and adverse events profiles should be considered to tailor the choice of the first-line agent. Sorafenib remains the most studied drug, with much real-world data available. The efficacy of second line therapies has only been proven in non-responder or sorafenib-intolerant patients. Unfortunately, studies directly comparing the second-line agents regorafenib, ramucirumab and cabozantinib are still lacking.
Insights
New targeted therapies and immune checkpoint inhibitors are expanding treatment options for advanced hepatocellular carcinoma (HCC). Lenvatinib offers a new first-line choice, while second-line treatments show promise for non-responders.
Area of Science:
- Hepatocellular Carcinoma (HCC) Research
- Oncology
- Pharmacotherapy
Background:
- Hepatocellular carcinoma (HCC) is the most common primary liver cancer with limited advanced-stage treatment options.
- Sorafenib, a tyrosine-kinase inhibitor (TKI), was the sole effective systemic treatment for unresectable HCC for ten years.
- Recent advancements have introduced new therapeutic possibilities for HCC management.
Purpose of the Study:
- To review recent advancements in pharmacotherapy for HCC.
- To discuss mechanisms of action, clinical efficacy, and safety of current HCC treatments.
- To analyze the role of immune checkpoint inhibitors (ICIs) in HCC therapy.
Main Methods:
- Analysis of recent literature on HCC pharmacotherapy.
- Discussion of first-, second-, and third-line treatment options.
- Evaluation of data on immune system modulators, including ICIs.
Main Results:
- Lenvatinib represents a significant advancement in HCC therapy, altering first-line treatment selection criteria.
- Sorafenib remains a well-documented option with extensive real-world data.
- Second-line therapies are effective in patients who do not respond to or tolerate sorafenib.
Conclusions:
- Treatment decisions for HCC should consider tumor characteristics, response rates, and adverse events.
- Further comparative studies are needed for second-line agents like regorafenib, ramucirumab, and cabozantinib.
- The therapeutic landscape for advanced HCC is rapidly evolving with new targeted and immune-based therapies.

Cancer Therapies
However, cancer treatments can pose several challenges, as therapies used to kill cancer cells are generally also toxic to normal cells. Moreover, cancer cells mutate rapidly and can develop resistance to chemical agents or radiation therapy. Besides, all types of cancer cells may not respond to the same therapy. Some cancer cells respond to one...
