84 samples from colorectal patients were analyzed. Paired tumor and adjacent normal tissues from the same patient were used for hybridization onto custom-made, 21k dual channel cDNA arrays. We prepared a similar number of samples from each of the three tumor locations (ascending 27, descending 29, and rectum 28) and recorded for each sample important molecular changes such as APC, TP53, RAF, WNT, and MMR mutations.
