Hierarchical cluster analysis. A, Two-dimensional hierarchical clustering of primary tumors per a 75-gene subset with differential expression across tumor specimen groups. Genes lie vertically and the GenBank accession numbers for all 75 genes are shown; specimens lie horizontally. Colors are mean, relative expression signal intensities for each gene. B, An enlarged view of the tumor specimen dendrogram from (A) along with a summary table of tumor specimen lymph node status.
