Molecular Profiling and Research of Therapeutic Targets

Area of Science:

• Hepatobiliary cancers
• Molecular oncology
• Cancer genetics

Background:

• Hepatocellular carcinoma (HCC) exhibits significant heterogeneity, complicating treatment efficacy.
• Advances in molecular profiling have identified key genetic events, such as telomerase promoter mutations in early carcinogenesis.
• Clinical translation of these molecular insights into practical HCC management remains a challenge.

Purpose of the Study:

• To review the progress in molecular profiling of hepatocellular carcinoma.
• To discuss the challenges and opportunities in translating genetic findings into clinical practice for HCC.
• To highlight emerging targeted therapies based on genetic stratification.

Main Methods:

• Review of recent literature on HCC molecular profiling.
• Analysis of genetic events in hepatocarcinogenesis.
• Evaluation of targeted therapy strategies for stratified HCC patient populations.

Main Results:

• Telomerase promoter mutations are early events in HCC development.
• Molecular stratification is improving therapeutic approaches for HCC.
• Targeted therapies show promise for specific molecular subtypes, including c-MET overexpression, VEGF-A amplification, and Wnt β-catenin-driven tumors.

Conclusions:

• Despite challenges, genetic information is increasingly guiding HCC therapy.
• Personalized treatment strategies based on molecular profiles are advancing HCC patient care.
• Targeted therapies represent a promising frontier for managing hepatocellular carcinoma.
