Abstract:
To date, despite extensive research, the prognosis of advanced osteosarcoma has not improved significantly. Thus, patients experience a reduced survival rate, suggesting that a reevaluation of current treatment strategies is required. Recently, in addition to routine surgery, chemotherapy and radiotherapy, researchers have explored more effective and safer treatments, including targeted therapy, immunotherapy, anti-angiogenesis therapy, metabolic targets therapy, and nanomedicine therapy. The tumorigenesis and development of osteosarcoma is closely related to angiogenesis. Thus, anti-angiogenesis therapy is crucial to treat osteosarcoma; however, recent clinical trials found that it has insufficient efficacy. To solve this problem, the causes of treatment failure and improve treatment strategies should be investigated. This review focuses on summarizing the pathophysiological mechanisms of angiogenesis in osteosarcoma and recent advances in anti-angiogenesis treatment of osteosarcoma. We also discuss some clinical studies, with the aim of providing new ideas to improve treatment strategies for osteosarcoma and the prognosis of patients.
Insights
Advanced osteosarcoma prognosis remains poor, necessitating new treatments. This review explores anti-angiogenesis therapy, examining its mechanisms and clinical efficacy to improve patient outcomes.
Area of Science:
- Oncology
- Biomedical Engineering
- Cancer Research
Background:
- Advanced osteosarcoma has a poor prognosis despite extensive research and current treatments like surgery, chemotherapy, and radiotherapy.
- Angiogenesis, the formation of new blood vessels, is closely linked to osteosarcoma tumorigenesis and development.
- Current anti-angiogenesis therapy shows insufficient efficacy in clinical trials, highlighting the need for improved strategies.
Purpose of the Study:
- To review the pathophysiological mechanisms of angiogenesis in osteosarcoma.
- To summarize recent advances in anti-angiogenesis treatment for osteosarcoma.
- To provide insights for improving osteosarcoma treatment strategies and patient prognosis.
Main Methods:
- Literature review of pathophysiological mechanisms of angiogenesis in osteosarcoma.
- Analysis of recent advances in anti-angiogenesis therapies.
- Discussion of relevant clinical studies and treatment outcomes.
Main Results:
- Angiogenesis plays a critical role in osteosarcoma progression.

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...
