The tumor microenvironment (TME) provides a guarantee for the survival and development of solid tumors. In recent years, treatment strategies for TME have set off a great upsurge in the field of cancer research. Tumor angiogenesis and tumor immune microenvironment are two important research branches of TME, and antiangiogenic therapy and immunotherapy have gradually become one important focus of cancer treatment research. More interestingly, increasing number of studies have indicated that there are complex regulatory interactions between the two treatment strategies, with multiple regulatory mechanisms involved. Based on these findings, clinical studies on the combination of immunotherapy and antiangiogenic therapy have also been carried out gradually. This combination strategy has shown good results in many types of tumors, but it also faces many challenges. The paper analysed the potential mechanism of the immunotherapy and antiangiogenic therapy combination, discussed the latest significant clinical trial progress and the existing challenges and problems, aiming to offer some available insights on the effective clinical application of this combination pattern.
