Diet-driven microbiome changes and physical activity in cancer patients

Area of Science:

• Oncology
• Microbiome Research
• Immunology

Background:

• The gut microbiome plays a significant role in shaping the immune system of cancer patients.
• A balanced gut microbial composition is essential for host-microorganism symbiosis.
• Intestinal dysbiosis is linked to cancer development and treatment, and modifiable lifestyle factors may restore balance.

Purpose of the Study:

• To review the interplay between the host and gut microbiome under various dietary patterns and physical activity.
• To explore the influence of nutrition on gut microbial communities in preclinical and clinical settings.
• To highlight the importance of nutritional status in cancer patient management.

Main Methods:

• Review of preclinical findings and clinical settings.
• Analysis of host-microbiome interactions influenced by diverse diets (high-fat, fiber-rich, rice and beans, Mediterranean, ketogenic) and physical activity.
• Synthesis of existing evidence on gut microbial composition and cancer.

Main Results:

• Nutrition is a critical determinant of gut microbial community composition.
• Different dietary patterns significantly impact the gut microbiome.
• Physical activity also influences the host-microbiome axis in cancer contexts.

Conclusions:

• Individualized dietary interventions and exercise plans can help maintain gut homeostasis.
• Optimizing the gut microbiome may enhance anti-cancer therapy response and improve survivor quality of life.
• Further research, including large clinical trials, is needed to elucidate mechanisms and establish personalized treatment strategies.
