Colorectal cancer (CRC) classification system that correlates cellular phenotype to clinical outcome

Computational analysis of drug-induced gene expression profiles in CRC provides a classification system that could be used to guide treatment decisions. Gene expression data from 1,290 CRC tumors were analyzed and mapped to a data set of clinical responses to the epidermal growth factor receptor (EGFR) inhibitor Erbitux cetuximab in 80 patients. Six subgroups were identified that corresponded to different levels of disease-free survival. For each subgroup, gene expression and protein biomarkers were identified that could be used to propose subtype-specific therapeutic strategies. Next steps include refining the quantitative gene expression approach and further validating the CRC subtype-specific signatures using additional retrospective sample sets.
Eli Lilly and Co. and partners Bristol-Myers Squibb Co. and Merck KGaA market Erbitux to treat CRC and head and neck cancer.
