Hierarchical cluster analysis of cancer tumor and benign prostate samples. The 83 metabolites determined to be significantly different (P < 0.05) between cancer tumor and matched benign tissue from eight patients were used to generate the cluster based on Euclidean distance. Metabolites are listed on the y-axis. Each patient is represented by a number (1 to 8) on the x-axis. Histologically determined cancer tumor (C) and matched benign (B) samples were used for the analysis. Cancer tumor and benign biopsies fall into two major clusters. Seven of eight cancer tumor and seven of eight benign samples clustered as predicted by the histological analysis of the biopsy.
