CrcBiomeScreen
Bioc currentAn R package for colorectal cancer screening and microbiome analysis
Release Lineage
Entered 3.23 · Apr 29, 2026
Current · Requires R 4.6
Description
A developed and benchmarked reproducible machine learning framework for microbiome-based colorectal cancer (CRC) screening. By systematically evaluating normalization strategies, taxonomic resolutions, and class imbalance handling. This R package allows users to apply the full pipeline or selectively run specific components depending on their analytical needs. It establishes a scalable foundation for developing interpretable microbiome-based screening tools to support early CRC detection. This approach could be easily implemented in a national screening programme, to improve early detection rates for this disease.
