Abstract:
The multikinase inhibitor sorafenib is the first oral molecular targeted agent with proven prognostic benefit in unresectable advanced hepatocellular carcinoma (HCC). However, as with other drugs, sorafenib has its limitations, and various clinical trials have been conducted to develop novel molecular targeted agents for use alone or in combination with existing locoregional therapies. Despite this, clinical trials of molecular targeted agents combined with transarterial chemoembolization (TACE) have not reported major treatment outcomes to date. In this review, we describe previous clinical trials of combination therapy with TACE and a molecular targeted agent in patients with unresectable HCC.
Insights
Sorafenib is an oral targeted therapy for advanced liver cancer (HCC). This review examines clinical trials combining transarterial chemoembolization (TACE) with targeted agents for unresectable HCC, noting limited reported outcomes.
Area of Science:
- Hepatobiliary cancers
- Medical oncology
- Interventional radiology
Background:
- Sorafenib, a multikinase inhibitor, offers prognostic benefit for unresectable hepatocellular carcinoma (HCC).
- Limitations of sorafenib necessitate development of novel molecular targeted agents.
- Combination therapies with locoregional treatments are under investigation for advanced HCC.
Purpose of the Study:
- To review clinical trials evaluating molecular targeted agents combined with transarterial chemoembolization (TACE) in unresectable HCC.
- To assess the reported treatment outcomes of TACE combined with molecular targeted agents.
Main Methods:
- Systematic review of published clinical trials.
- Focus on studies involving unresectable HCC patients treated with TACE and molecular targeted agents.
- Analysis of reported efficacy and safety data.
Main Results:
- Clinical trials combining TACE with molecular targeted agents for unresectable HCC have not yet reported major treatment outcomes.
- Limited data exists on the efficacy and safety of these combination therapies.
Conclusions:
- Further research and well-designed clinical trials are needed to establish the role of TACE combined with molecular targeted agents in unresectable HCC.
- Identifying optimal combinations and treatment strategies remains a critical unmet need.
