Background:
Head and neck squamous cell carcinoma (HNSCC) carries poor survival outcomes despite recent progress in cancer treatment in general. Angiogenesis is crucial for tumour survival and progression. Therefore, several agents targeting the pathways that mediate angiogenesis have been developed. We conducted a systematic review to summarise the current clinical trial data examining angiogenesis inhibitors in HNSCC.
Methods:
We carried out a literature search on three angiogenesis inhibitor categories-bevacizumab, tyrosine kinase inhibitors and endostatin-from Ovid MEDLINE, Cochrane Library, Scopus and ClinicalTrials.gov database.
Results:
Here, we analysed 38 clinical trials, total of 1670 patients, investigating 12 angiogenesis inhibitors. All trials were in phase I or II, except one study in phase III on bevacizumab. Angiogenesis inhibitors were used as mono- and combination therapies together with radio-, chemo-, targeted- or immunotherapy. Among 12 angiogenesis inhibitors, bevacizumab was the most studied drug, included in 13 trials. Although bevacizumab appeared effective in various combinations, it associated with high toxicity levels. Endostatin and lenvatinib were well-tolerated and their anticancer effects appeared promising.
Conclusions:
Most studies did not show benefit of angiogenesis inhibitors in HNSCC treatment. Additionally, angiogenesis inhibitors were associated with considerable toxicity. However, some results appear encouraging, suggesting that further investigations of angiogenesis inhibitors, particularly in combination therapies, for HNSCC patients are warranted.

Insights
Angiogenesis inhibitors show limited benefit and significant toxicity in head and neck squamous cell carcinoma (HNSCC) treatment. Further research into combination therapies is warranted for HNSCC patients.
Area of Science:
- Oncology
- Cancer Research
- Clinical Trials
Background:
- Head and neck squamous cell carcinoma (HNSCC) has poor survival rates despite advances in cancer treatment.
- Angiogenesis is vital for tumor growth and progression, leading to the development of angiogenesis inhibitors.
- This systematic review evaluates clinical trial data on angiogenesis inhibitors for HNSCC.
Approach:
- A literature search was conducted across multiple databases (Ovid MEDLINE, Cochrane Library, Scopus, ClinicalTrials.gov).
- The review focused on three categories of angiogenesis inhibitors: bevacizumab, tyrosine kinase inhibitors, and endostatin.
- 38 clinical trials involving 1670 patients were analyzed.
Key Points:
- Bevacizumab was the most studied agent but associated with high toxicity.
- Endostatin and lenvatinib demonstrated promising anticancer effects and good tolerability.
- Most trials were Phase I or II, with one Phase III trial on bevacizumab.
Conclusions:
- Angiogenesis inhibitors generally did not demonstrate significant benefit in HNSCC treatment.
- Considerable toxicity was observed with angiogenesis inhibitors.
- Encouraging results suggest further investigation, especially in combination therapies, is warranted for HNSCC.

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...
