The cure from within? a review of the microbiome and diet in melanoma

Area of Science:

• Immunology
• Oncology
• Microbiology

Background:

• Cutaneous melanoma therapy increasingly relies on the immune system.
• Immune checkpoint inhibitors offer cures for metastatic melanoma but only benefit half of patients.
• The gut microbiome's role in immune health and melanoma development/treatment is an emerging area of research.

Purpose of the Study:

• To review the significance of the skin and gut microbiome in melanoma development.
• To examine microbial population differences in melanoma patients responding to immunotherapy.
• To discuss dietary impacts and therapeutic strategies targeting the microbiome in melanoma treatment.

Main Methods:

• Literature review of scientific publications.
• Analysis of clinical trial data (published and registered).
• Examination of microbial population differences and their correlation with treatment response.

Main Results:

• The gut microbiome composition differs in individuals with melanoma and those who respond to immunotherapy.
• Dietary intake significantly influences melanoma development and treatment efficacy.
• Various therapeutic approaches targeting the microbiome are under investigation.

Conclusions:

• The gut microbiome is a critical factor in melanoma immunotherapy.
• Modulating the gut microbiome via diet or transplantation holds promise for enhancing melanoma treatment.
• Further research and clinical trials are essential to optimize microbiome-based melanoma therapies.
