Abstract:
Anti-angiogenesis therapy, a promising strategy against cancer progression, is limited by drug-resistance, which could be attributed to changes within the tumor microenvironment. Studies have increasingly shown that combining anti-angiogenesis drugs with immunotherapy synergistically inhibits tumor growth and progression. Combination of anti-angiogenesis therapy and immunotherapy are well-established therapeutic options among solid tumors, such as non-small cell lung cancer, hepatic cell carcinoma, and renal cell carcinoma. However, this combination has achieved an unsatisfactory effect among some tumors, such as breast cancer, glioblastoma, and pancreatic ductal adenocarcinoma. Therefore, resistance to anti-angiogenesis agents, as well as a lack of biomarkers, remains a challenge. In this review, the current anti-angiogenesis therapies and corresponding drug-resistance, the relationship between tumor microenvironment and immunotherapy, and the latest progress on the combination of both therapeutic modalities are discussed. The aim of this review is to discuss whether the combination of anti-angiogenesis therapy and immunotherapy can exert synergistic antitumor effects, which can provide a basis to exploring new targets and developing more advanced strategies.
Insights
Anti-angiogenesis therapy combined with immunotherapy shows promise for solid tumors but faces resistance challenges. This review explores overcoming resistance and optimizing combination strategies for better cancer treatment outcomes.
Area of Science:
- Oncology
- Immunology
- Pharmacology
Background:
- Anti-angiogenesis therapy is a key cancer treatment strategy, but drug resistance, often linked to the tumor microenvironment, limits its efficacy.
- Combining anti-angiogenesis drugs with immunotherapy has demonstrated synergistic antitumor effects in several solid tumors, including lung, liver, and kidney cancers.
- However, this combination therapy shows unsatisfactory results in certain cancers like breast cancer, glioblastoma, and pancreatic ductal adenocarcinoma, highlighting unmet needs.
Purpose of the Study:
- To review current anti-angiogenesis therapies and the mechanisms of drug resistance.
- To discuss the intricate relationship between the tumor microenvironment and immunotherapy efficacy.
- To evaluate the latest advancements in combining anti-angiogenesis therapy and immunotherapy for synergistic antitumor effects and explore new therapeutic strategies.
Main Methods:
- Literature review of current anti-angiogenesis therapies and drug resistance mechanisms.
- Analysis of the role of the tumor microenvironment in modulating immunotherapy response.
- Synthesis of recent research on the combination of anti-angiogenesis therapy and immunotherapy.
Main Results:
- Combination therapy is effective in specific solid tumors but faces challenges in others due to resistance.
- Tumor microenvironment modulation is crucial for enhancing the efficacy of combined anti-angiogenesis and immunotherapy.
- Lack of predictive biomarkers for resistance remains a significant hurdle.
Conclusions:
- Combining anti-angiogenesis therapy with immunotherapy holds significant potential for synergistic antitumor effects.
- Addressing drug resistance and understanding the tumor microenvironment are critical for optimizing this combination strategy.
- Further research is needed to identify new targets and develop advanced therapeutic approaches for challenging tumors.

Cancer Therapies
However, cancer treatments can pose several challenges, as therapies used to kill cancer cells are generally also toxic to normal cells. Moreover, cancer cells mutate rapidly and can develop resistance to chemical agents or radiation therapy. Besides, all types of cancer cells may not respond to the same therapy. Some cancer cells respond to one...
