Gut microbiota and its therapeutic implications in tumor microenvironment interactions

Area of Science:

• Oncology
• Microbiology
• Immunology

Background:

• Cancer development involves complex interactions within the tumor microenvironment (TME).
• The TME, including the gut microbiome, plays a critical role in tumor initiation, progression, metastasis, and treatment response.
• Current TME-targeted therapies show insufficient clinical efficacy.

Purpose of the Study:

• To review the role of gut microbiota in human cancers.
• To explore the interaction between gut microbiota and the TME.
• To highlight potential applications of gut microbiota in cancer therapeutics.

Main Methods:

• Literature review summarizing existing research on gut microbiota and cancer.
• Analysis of the interplay between gut microbiota and the tumor microenvironment.
• Discussion of novel therapeutic strategies.

Main Results:

• The gut microbiome is an essential component of the TME, crucial for cancer immunotherapy.
• Frameworks linking gut microbiota and TME can enhance cancer treatment strategies.
• Fecal microbiota transplantation, dietary changes, and synthetic biology are promising gut microbiota-based approaches.

Conclusions:

• Understanding the gut microbiota-TME axis is vital for developing effective cancer treatments.
• This review provides a foundation for personalized medicine approaches targeting the gut microbiome in cancer care.
