Redefining the tumor microenvironment with emerging therapeutic strategies

Area of Science:

• Oncology and Cancer Biology
• Immunotherapy
• Molecular Biology

Background:

• The tumor microenvironment (TME) significantly influences cancer progression and therapeutic response.
• Understanding TME complexity presents both challenges and opportunities for novel cancer therapies.
• Recent advancements in TME research have spurred innovative treatment approaches.

Purpose of the Study:

• To discuss current strategies for targeting the tumor microenvironment in cancer treatment.
• To highlight the potential of adoptive cell transfer (ACT) therapies.
• To emphasize the need for reshaping the TME to improve treatment efficacy and overcome resistance.

Main Methods:

• Review of strategies including extracellular vesicle-mediated drug delivery and combination therapies with immune checkpoint inhibitors (ICIs).
• Exploration of adoptive cell transfer (ACT) as a therapeutic option.
• Utilizing advanced technologies such as single-cell RNA sequencing and spatial transcriptomics for TME component interaction studies.

Main Results:

• Targeting TME networks with extracellular vesicles can facilitate drug delivery.
• Combination treatments can enhance the efficacy of immune checkpoint inhibitors (ICIs).
• Adoptive cell transfer (ACT) therapies show promise for treating tumors within specific microenvironments.

Conclusions:

• Studying TME component interactions is crucial for developing precise and effective cancer treatments.
• Reshaping the TME is essential for boosting antitumor immunity and overcoming therapeutic resistance.
• This perspective provides guidance for future research and clinical practices in precision oncology.
