Research Abstract

Based on the gene expression of rectal cancer, we aimed to build a predictive model for response to chemoradiotherapy. Using 46 samples as a training set, we examined gene expression by microarray and RT-PCR. We finally selected 4 genes that were used for predictive model. The accuracy rate of prediction was 89.1% among a training set. In an independent test set of 16 samples, we validated the accuracy of a predictive model and the accuracy rate of the predictive model was 81.3%.
