Targeting angiogenesis for liver cancer: Past, present, and future
摘要
Abstract
Liver cancer
mostly hepatocellular carcinoma (HCC)
is the second leading cause of cancer mortality globally. Most patients were diagnosed at an advanced stage
and systemic therapy is the standard of care. All the approved systemic therapies for HCC are molecular targeted therapies with anti-angiogenic effects targeting the vascular endothelial growth factor signaling pathway. Sorafenib and lenvatinib are the first-line treatment
and regorafenib
ramucirumab
and cabozantinib are second-line treatment options. Although anti-PD-1 antibodies
including nivolumab and pembrolizumab
demonstrated promising anti-tumor effects as monotherapy for advanced HCC in phase II clinical trials
both failed in phase III studies. Anti-angiogenic treatment remains the backbone of systemic therapy for HCC. In this review
we summarized the approved anti-angiogenic medicines and discussed the potential strategies to improve the efficacy of anti-angiogenic therapy
including combination therapy with other treatments
and discussed the approaches to overcome the drawbacks of anti-angiogenic therapies.
