Abstract:
Effective cancer therapy remains a challenge despite recent advances in the identification of novel targets. A major limitation of most chemotherapeutic drugs is their systemic toxicity and the efficacy of cancer treatments is, by and large, determined by the ability to balance their benefits against their toxicity. Targeted treatments for cancer, especially those that target the tumor vasculature, have provided promising antitumor results with minimal systemic toxicity. To date significant progress has been made in developing a variety of delivery systems to target cancer and its vasculature ranging from isolated limb and organ perfusion to tumor targeted biological and nonbiological vectors.
Insights
Targeted cancer therapies, particularly those focusing on tumor vasculature, offer a promising approach to minimize systemic toxicity. Advances in delivery systems aim to improve treatment efficacy by selectively targeting cancer cells and their blood supply.
Area of Science:
- Oncology
- Nanotechnology
- Drug Delivery Systems
Background:
- Cancer therapy faces challenges due to systemic toxicity of conventional chemotherapeutics.
- Balancing treatment benefits against toxicity is crucial for effective cancer care.
- Targeted therapies, especially those against tumor vasculature, show promise for reduced side effects.
Purpose of the Study:
- To review advancements in targeted cancer treatment strategies.
- To highlight the potential of targeting tumor vasculature for improved efficacy and reduced toxicity.
- To discuss various delivery systems developed for cancer targeting.
Main Methods:
- Literature review of targeted cancer therapies.
- Analysis of strategies focusing on tumor vasculature.
- Examination of different biological and non-biological delivery vectors.
Main Results:
- Targeted approaches, particularly those impacting tumor vasculature, demonstrate significant antitumor activity.
- Delivery systems show progress in selectively targeting cancerous tissues.
- Reduced systemic toxicity is a key advantage of these targeted methods.
Conclusions:
- Targeting tumor vasculature is a viable strategy for effective cancer treatment.
- Development of advanced delivery systems is critical for successful targeted cancer therapy.
- Future research should focus on optimizing these systems for enhanced patient outcomes.

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...
