Vanderbilt-Ingram Cancer Center Unveils Comprehensive Transcriptomic Atlas to Enhance Breast Cancer Treatment Precision
Researchers at Vanderbilt-Ingram Cancer Center have developed one of the largest transcriptomic maps of breast cancer to date. This comprehensive atlas, detailed in Cell Reports Medicine, integrates 7,612 breast cancer transcriptomes from 22 independent datasets, providing an unprecedented view of the disease's molecular diversity. The team, led by Brian Lehmann, PhD, Research Associate Professor of Medicine, identified 12 breast cancer-intrinsic subtypes and three major tumor microenvironment programs, collectively named the integrated Breast Cancer Transcriptome Classification (iBTC). This atlas reveals previously unrecognized forms of breast cancer with distinct prognoses, biological characteristics, and therapeutic vulnerabilities, moving beyond traditional classifications to enable more precise and effective treatment decisions.
