Full genome expression profiling of primary colorectal cancer (CRC)


ABSTRACT: Fresh-frozen primary tumor samples from CRC patients were analyzed from their gene expression. Full genome unsupervised clustering identified three intrinsic subtypes that are associated with tumor and clinical characteristics. Primary CRC samples (188) were hybridzed against a common colon cancer reference pool (CRP).

In most colorectal cancer (CRC) patients, outcome cannot be predicted because tumors with similar clinicopathological features can have differences in disease progression and treatment response. Therefore, a better understanding of the CRC biology is required to identify those patients who will benefit from chemotherapy and to find a more tailored therapy plan for other patients. Based on unsupervised classification of whole genome data from 188 stages I-IV CRC patients, a molecular classificati  ...[more]
