Feature subset selection for outcome prediction is a critical issue inlarge scale microarray experiments in cancer research. This paper introduces anintegrative approach that combines significant gene expression analysis, the geneticalgorithm and machine learning for selecting informative gene markersand for predicting tumor outcomes including survival outcomes. In case of survivaldata, full use of individual's survival information (both censored anduncensored) is made in selecting informative genes for survival outcome prediction.Applications of our method to published microarray data on epithelialovarian cancer survival and breast cancer metastasis have identified prognosticgenes that predict individual survival and metastatic outcomes with improvedpower while basing on considerably shorter gene lists.
