Targeting tumor vascularization: promising strategies for vascular normalization

Area of Science:

• Oncology
• Vascular Biology
• Cancer Therapeutics

Background:

• Tumor recurrence post-treatment is frequently associated with an abnormal tumor microenvironment, particularly aberrant tumor vasculature.
• Tumor microenvironments exhibit an imbalance of pro-angiogenic and pro-maturation factors, leading to abnormal blood vessel networks.
• Hypoxia within tumors, while promoting some repair, also drives aberrant neovascularization, impacting tumor progression and metastasis.

Purpose of the Study:

• To review the process of tumor vascularization and its role in tumor recurrence.
• To identify potential therapeutic targets within the tumor microenvironment for vascular normalization.
• To explore strategies for normalizing tumor vasculature to improve cancer treatment outcomes.

Main Methods:

• Review of existing literature on tumor angiogenesis and vascular biology.
• Analysis of therapeutic targets including cellular components, metabolic pathways, signaling pathways, and angiogenesis-related genes.
• Examination of strategies for regulating tumor vessel generation, development, and remodeling.

Main Results:

• Traditional anti-angiogenic therapies have limited efficacy and can promote resistance and metastasis.
• Vascular normalization therapy aims to create a more physiological vascular state, improving oxygenation and substance transport.
• Normalization enhances the efficacy of radiotherapy, chemotherapy, and immunotherapy.

Conclusions:

• Aberrant tumor vasculature is a key factor in tumor recurrence and treatment failure.
• Vascular normalization represents a promising therapeutic approach to overcome limitations of traditional anti-angiogenic strategies.
• Targeting tumor vascularization offers a pathway to improve overall cancer treatment effectiveness and patient outcomes.
