When human cells meet bacteria: precision medicine for cancers using the microbiota

Area of Science:

• Microbiome research
• Cancer biology
• Immunology

Background:

• The human microbiota plays a role in host immune system regulation.
• The intricate relationship between the microbiome and cancer development is not fully understood.
• Current evidence primarily shows associations, not causation, between microbial changes and carcinogenesis.

Purpose of the Study:

• To review the impact of the microbiota on cancer initiation, development, and progression.
• To explore the clinical translation of microbiome research for cancer diagnosis and treatment.
• To highlight the complexity of microbiome-host-immune system interactions.

Main Methods:

• Literature review of existing studies on the human microbiota and cancer.
• Analysis of the role of microbial alterations in various human cell types.
• Focus on clinical applications of microbiome research in oncology.

Main Results:

• The microbiota significantly impacts cancer initiation and progression.
• Understanding the microbiome's role is crucial for advancing cancer care.
• Complex regulatory loops exist between the microbiome, host cells, and the immune system.

Conclusions:

• Further studies are essential to elucidate the causal mechanisms linking the microbiome and cancer.
• Microbiome research holds potential for improving cancer diagnosis, classification, and precision medicine.
• Translating microbiome findings into clinical practice requires a deeper understanding of these interactions.
