Angiogenesis Inhibitors in Liver Cancer Therapy
Targeted agents blocking tumor vascularization in hepatocellular carcinoma (HCC) and cholangiocarcinoma, from historical milestones to 2025 advancements.
Overview of Angiogenesis Inhibitors
Evolution from foundational discoveries to cornerstone therapies in liver cancer management.
The journey of angiogenesis inhibitors began in 1971 with Judah Folkman's hypothesis that tumors require new blood vessels to grow, revolutionizing oncology. Progress accelerated with the first approval of bevacizumab in 2004 for colorectal cancer, followed by sorafenib for HCC in 2007, marking the first systemic therapy improving survival in advanced liver cancer.
Today, in 2025, these agents have advanced to multi-tyrosine kinase inhibitors (TKIs) like lenvatinib and cabozantinib, targeting VEGF, FGF, and PDGF pathways. Combinations with immune checkpoint inhibitors (ICIs) like atezolizumab + bevacizumab have become standard, achieving 45% objective response rates in advanced HCC. Lessons from the past highlight resistance mechanisms, leading to biomarker-driven approaches.
Medical disagreements persist on optimal sequencing—first-line anti-angiogenics vs. immunotherapy—and managing side effects like hypertension. Latest articles emphasize synergistic TACE + targeted therapy for intermediate-stage HCC, with emerging small molecules targeting HCC stem cells showing promise.
Future hopes lie in AI-guided discovery of novel targets and nanoparticle delivery for enhanced efficacy with reduced toxicity.
