[Research progress of anti-angiogenic drugs in the treatment of small cell lung cancer].

ABSTRACT

Small cell lung cancer (SCLC), a special type of lung cancer, is a highly malignant neuroendocrine tumor with strong invasiveness and rapid progression. SCLC is sensitive to radiotherapy and chemotherapy, so radiotherapy and chemotherapy have been the main first-line treatment of SCLC. However, it is easy to develop drug resistance after treatment. Therefore, the study of anti-angiogenic therapy has attracted more and more attention. At present, anti-angiogenic drugs mainly focus on four categories monoclonal antibodies (such as bevacizumab), endogenous angiogenesis inhibitors (such as endostar), anti-angiogenic fusion protein (such as aflibercept) and small molecular tyrosine kinase inhibitors (such as anlotinib). There are still some bottlenecks in the research and clinical application of antiangiogenic drugs. It is the right direction to explore better combination therapy and effective dual-field and multi-target drugs.
