Anti-vascular tumor therapy: recent advances, pitfalls and clinical perspectives

Area of Science:

• Oncology
• Cancer Therapeutics
• Vascular Biology

Background:

• Anti-vascular tumor therapy is a novel cancer treatment strategy.
• It encompasses anti-angiogenic and vascular targeting therapies.
• Both approaches aim to inhibit tumor growth by targeting blood vessels.

Purpose of the Study:

• To review recent advances in anti-vascular therapy, focusing on vascular targeting.
• To discuss the conceptual differences between anti-angiogenic and vascular targeting therapies.
• To highlight challenges in translating these therapies into clinical practice.

Main Methods:

• Review of preclinical and clinical studies on anti-vascular therapies.
• Analysis of therapeutic strategies including monotherapy and combination treatments.
• Discussion of clinical trial outcomes and translational challenges.

Main Results:

• Both anti-angiogenic and vascular targeting agents demonstrate anti-tumoral activity in preclinical studies.
• Combination therapy, particularly anti-angiogenic therapy with chemotherapy, shows significant efficacy in clinical trials (e.g., metastatic colorectal cancer).
• Anti-angiogenic monotherapy has shown limited efficacy in randomized clinical studies.

Conclusions:

• Anti-vascular therapies, especially vascular targeting, offer a promising avenue for cancer treatment.
• Combination strategies are crucial for enhancing therapeutic efficacy.
• Further research is needed to overcome challenges in clinical translation and optimize treatment protocols.
