The Association between the Gut Microbiome and Development and Progression of Cancer Treatment Adverse Effects

Area of Science:

• Oncology
• Microbiology
• Gastroenterology

Background:

• Adverse effects are common in cytotoxic cancer therapy.
• The gut microbiome's role in treatment side effects is increasingly recognized.
• Existing research links gut microbiome alterations to acute gastrointestinal issues like diarrhea and mucositis.

Purpose of the Study:

• To review and synthesize current literature on the gut microbiome's association with cytotoxic cancer treatment adverse effects.
• To identify the microbiome's potential contributions to both acute and long-term treatment toxicities.

Main Methods:

• Literature review of studies investigating the gut microbiome and cancer treatment side effects.
• Analysis of associations between microbiome alterations and various adverse events.
• Synthesis of findings on acute and long-term consequences.

Main Results:

• Gut microbiome dysbiosis is associated with acute adverse effects such as diarrhea and mucositis.
• Emerging evidence suggests a link between the gut microbiome and long-term effects including psychoneurological changes, cancer cachexia, and fatigue.
• The gut microbiome plays a significant role in the overall toxicity profile of cancer treatments.

Conclusions:

• The gut microbiome is a critical factor influencing the development and severity of adverse effects from cytotoxic cancer treatments.
• Targeting the gut microbiome may offer novel strategies for mitigating treatment-related toxicities.
• Further research is warranted to fully elucidate the complex interactions between the gut microbiome and cancer therapy outcomes.
