Why angiogenesis inhibition? Commentary

Abstract:
Over the last several decades, cancer research and therapy have focused primarily on tumor cells. However, in 1971 it was proposed that a solid tumor cannot grow without recruiting endothelial cells. The hypothesis was that if one can block the formation of an adequate capillary network, tumor growth could be inhibited. Antiangiogenesis research is undoubtedly very fashionable today but compounds effective in clinical trials have not been reported so far. The goal of this commentary is to discuss two questions: what are the limitations of the old, established antitumor paradigm? Second, what are the advantages of the antiangiogenesis paradigm? At this time it is important to convince more scientists that the inhibition of angiogenesis is a valid concept against tumor growth. A stronger momentum of the antiangiogenesis movement will hopefully result in finding more effective compounds against cancer growth.
Insights
Targeting tumor blood vessel formation, or antiangiogenesis, offers a promising strategy to inhibit cancer growth. This approach complements traditional tumor cell-focused therapies, addressing limitations in current cancer treatment paradigms.
Area of Science:
- Oncology
- Cancer Biology
- Vascular Biology
Background:
- Traditional cancer research has primarily focused on tumor cells.
- A 1971 hypothesis proposed that inhibiting tumor-induced blood vessel formation (angiogenesis) could halt tumor growth.
- Despite current interest, antiangiogenesis therapies have yet to yield effective clinical compounds.
Purpose of the Study:
- To discuss the limitations of established anti-tumor therapy paradigms.
- To highlight the advantages of the antiangiogenesis paradigm in cancer treatment.
- To advocate for increased scientific focus on angiogenesis inhibition as a valid anti-cancer strategy.
Main Methods:
- This commentary critically evaluates existing anti-cancer strategies.
- It contrasts the established tumor-centric approach with the antiangiogenesis paradigm.
- It discusses the potential and challenges of targeting tumor vasculature.
Main Results:
- Established anti-tumor therapies face limitations in effectively eradicating all cancer.
- The antiangiogenesis paradigm presents a complementary strategy by targeting tumor support systems.
- Further research is needed to overcome challenges and develop effective antiangiogenesis compounds.
Conclusions:
- Antiangiogenesis is a valid and crucial concept for inhibiting tumor growth.
- Overcoming the limitations of current cancer treatments requires exploring novel therapeutic avenues.
- Increased momentum in antiangiogenesis research is essential for discovering effective 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...
