Hierarchical Clustering of Expression Levels in Colon Tumors. Expression levels of 129 genes in 41 colorectal tumor samples were analyzed by hierarchical clustering (distance metric: Peason Uncentered, linkage rule; Average). L-adenoma, LST-adenoma; L-carcinoma, LST-carcinoma; P-adenoma, Ip-adenoma. These samples were divided into 3 clusters. Group 1 consists of LST-adenomas and Ip-adenomas, Group 2 mainly consists of LST-adenomas and Group 3 mainly consists of LST-carcinomas
