Abstract:
Angiogenesis is an integral aspect of the growth and proliferation of solid tumors, including head and neck squamous cell carcinoma (HNSCC), and has potential implications in prognosis and treatment of both localized and recurrent/metastatic HNSCC. Therefore, there has been a significant interest in utilizing anti-angiogenic agents either alone or in combination with currently approved and emerging therapies. A phase III randomized trial (E1305) of chemotherapy with or without bevacizumab in the first-line treatment of recurrent/metastatic HNSCC showed an increased response rate and longer progression-free survival but fell short in demonstrating a statistically significant improved survival with bevacizumab. Moreover, toxicity, especially bleeding, was increased. Nevertheless, the study of other anti-angiogenic agents and novel combinations with other therapies, including immunotherapy, remains of interest. Several clinical trials are currently underway.
Insights
Anti-angiogenic therapy, like bevacizumab, showed promise in improving progression-free survival for head and neck squamous cell carcinoma (HNSCC) but did not significantly extend overall survival and increased bleeding risks.
Area of Science:
- Oncology
- Cancer Research
Background:
- Angiogenesis, the formation of new blood vessels, is crucial for solid tumor growth, including head and neck squamous cell carcinoma (HNSCC).
- Anti-angiogenic agents are being investigated for their potential in treating localized and metastatic HNSCC.
Purpose of the Study:
- To evaluate the efficacy and safety of adding bevacizumab to chemotherapy in the first-line treatment of recurrent/metastatic HNSCC.
Main Methods:
- A phase III randomized trial (E1305) compared chemotherapy with or without bevacizumab in patients with recurrent/metastatic HNSCC.
Main Results:
- The addition of bevacizumab led to a higher response rate and longer progression-free survival.
- However, bevacizumab did not significantly improve overall survival and was associated with increased toxicity, particularly bleeding.
Conclusions:
- While bevacizumab demonstrated some benefits in progression-free survival for HNSCC, its impact on overall survival and increased toxicity warrant careful consideration.
- Further research into other anti-angiogenic agents and novel combinations, including immunotherapy, is ongoing.

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...
