Who could benefit from this research

Could help

Ideal candidates are adults involved in the NHS II or SCCS cohorts who have provided stool samples and have longitudinal lifestyle and clinical data available.

Less likely to help

Individuals not enrolled in the referenced cohorts or without available stool/lifestyle data may not directly benefit from this study.

What this research studies

This project will follow tens of thousands of participants from long-running studies to collect stool samples and lifestyle data, then examine how gut microbes and their metabolic products relate to colorectal neoplasia. By integrating dietary patterns, physical activity, aspirin use, and microbial signals, the study aims to identify drivers and passengers of tumor formation in a diverse population. The investigators will use prospective sample data to explore whether microbial changes predict, precede, or accompany adenoma development. Findings could point toward personalized prevention strategies and biomarkers for early detection. The work is anchored at Harvard School of Public Health with collaboration across large cohorts to ensure broad relevance.

Why it matters

Potential benefit: If successful, the research could lead to new ways to prevent colorectal cancer through tailored lifestyle recommendations and microbiome-based biomarkers.

How similar studies have gone: Prior observational work has linked lifestyle and microbiome factors to colorectal neoplasia, but this large prospective, diverse-cohort study is among the first to integrate these elements at this scale.
