Background:
The effectiveness of conventional chemotherapy in treating metastatic triple-negative breast cancer (TNBC) is unsatisfactory. Apatinib, a small-molecule tyrosine kinase vascular inhibitor, is a multi-targeted antitumor angiogenesis agent that promotes apoptosis to inhibit tumors.
Summary:
Apatinib, when combined with chemotherapy, has demonstrated efficacy in treating advanced TNBC. Additionally, immune checkpoint inhibitors (ICIs) have emerged as a promising therapeutic option for metastatic TNBC; however, their efficacy still requires further improvement. One potential strategy to enhance the efficacy of ICIs in metastatic TNBC is through their combination with chemotherapy and anti-angiogenic agents. The combination of apatinib, chemotherapy, and ICIs has demonstrated favorable efficacy, with improved progression-free survival compared with the conventional chemotherapy for advanced TNBC. This warrants further exploration of its clinical value. This triple therapy exhibits synergistic effects rather than representing a simple combination of agents. Apatinib can reverse chemoresistance and enhance the efficacy of programmed death receptor-1 (PD-1) inhibitor therapy. Combining chemotherapeutic agents with ICIs is complementary, and apatinib, combined with chemotherapy, can modify the tumor microenvironment to improve the effectiveness of ICIs.
Key Messages:
This review examines the role of apatinib in treating TNBC and explores its potential mechanisms when combined with chemotherapeutic agents and ICIs for advanced TNBC in the era of immunotherapy.
Insights
Apatinib combined with chemotherapy and immune checkpoint inhibitors shows improved outcomes for advanced triple-negative breast cancer (TNBC). This triple therapy enhances progression-free survival compared to chemotherapy alone, offering a promising new treatment strategy.
Area of Science:
- Oncology
- Immunotherapy
- Pharmacology
Background:
- Metastatic triple-negative breast cancer (TNBC) shows limited response to conventional chemotherapy.
- Apatinib, a tyrosine kinase inhibitor (TKI), targets tumor angiogenesis and promotes apoptosis.
- Immune checkpoint inhibitors (ICIs) offer potential for advanced TNBC but require efficacy enhancement.
Purpose of the Study:
- To review the role of apatinib in treating TNBC.
- To explore the mechanisms of apatinib in combination therapies for advanced TNBC.
- To evaluate the efficacy of combining apatinib, chemotherapy, and ICIs.
Main Methods:
- Literature review of studies on apatinib, chemotherapy, and ICIs in advanced TNBC.
- Analysis of clinical trial data and preclinical research.
- Examination of proposed mechanisms of action for combination therapies.
Main Results:
- Combination of apatinib with chemotherapy and ICIs demonstrates improved progression-free survival (PFS) in advanced TNBC.
- Apatinib can overcome chemoresistance and enhance the efficacy of PD-1 inhibitors.
- The triple therapy exhibits synergistic effects, modifying the tumor microenvironment.
Conclusions:
- Apatinib combined with chemotherapy and ICIs is an effective strategy for advanced TNBC.
- This triple therapy offers a promising approach to improve outcomes in the era of immunotherapy.
- Further clinical exploration of this combination therapy is warranted.
