Tumor Microenvironment and Its Role in Cancer Progression and Therapeutic Resistance

Abstract

Background: The tumor microenvironment (TME) plays a critical role in cancer development, progression, and resistance to therapy.

Objective: To examine the components of the TME and their influence on tumor growth and treatment resistance.

Methods: Recent literature on cellular and molecular interactions within the TME, including immune cells, stromal components, and signaling pathways, was reviewed.

Results: The TME contributes to tumor progression by promoting angiogenesis, immune evasion, and metastasis. Interactions between cancer cells and surrounding stromal cells facilitate resistance to chemotherapy and immunotherapy. Targeting the TME, particularly immune checkpoints and stromal pathways, has shown potential in improving therapeutic outcomes.

Conclusion: Understanding the tumor microenvironment is essential for developing effective cancer therapies. Future strategies should focus on TME-targeted interventions to enhance treatment efficacy.
