The potential of lenvatinib in breast cancer therapy.

Abstract

Breast cancer, as a highly prevalent cancer among women, is one of the main causes of female mortality due to cancer. There is a need for more treatment options to improve the survival time of breast cancer patients. Metastasis to distant organs is a standard indicator of advanced breast cancer and a primary cause of breast cancer mortality, making the control of breast cancer metastasis crucial. Targeted therapy, with its advantages of precision, high effectiveness, and minimal side effects, has garnered significant attention as a hot research topic in breast cancer treatment. Among these therapies, anti-angiogenic therapy aim to inhibit tumor angiogenesis, control tumor growth, and reduce metastasis. Additionally, anti-angiogenic therapy can restructure the tumor vasculature, enhancing the effectiveness of other anti-cancer drugs. Lenvatinib, an orally available small molecule multi-targeted tyrosine kinase inhibitor, exerts its anti-tumor effects mainly by inhibiting tumor angiogenesis and tumor cell proliferation. It has been approved for the treatment of thyroid cancer, renal cell carcinoma, and hepatocellular carcinoma. Due to its multi-targeted nature, lenvatinib not only has direct anti-tumor effects but also possesses immunomodulatory activity, which can enhance the tumor immune response. This makes it a promising candidate for a broad range of cancers. Recent studies have explored the role of lenvatinib in breast cancer, including its various mechanisms of action and its use as a monotherapy or in combination to control breast cancer progression. This review will summarize the molecular mechanisms and research progress of lenvatinib in breast cancer treatment, discussing its potential applications and therapeutic prospects in managing breast cancer.
