Mayo Clinic Study Links Pre-Treatment Gut Microbes to Cancer Survival and Chemo Side Effects
A large-scale study by Mayo Clinic researchers, published in Cell, identifies distinct gut bacterial signatures in 1,364 cancer patients that correlate with specific cancer types, survival rates, and chemotherapy side effects. The findings suggest that pre-treatment microbiome profiles may predict outcomes, particularly for colorectal and breast cancers in younger adults, and link specific bacteria to diarrhea caused by the drug 5-fluorouracil.
