Cluster analysis of ovarian tumour expression profiles. Gene expression profiles were obtained from eighteen ovarian tumours. The profiles were analysed by clustering methods in several groups: (a) self organizing map of he thirteen patients not receiving chemotherapy prior to tissue collection, (b) hierarchical clustering of the same 13 patients, (d) self organizing maps of all eighteen patients and (e) hierarchical clustering of all 18 patients. Marker analysis (c) identified the top ten gene most highly correlated with clusters resulting from (a) and (b).
