Abstract: The method for predicting the anti-tumor response in a human or animal having a tumor to multiple kinase inhibitors, using any multiple kinase inhibitor, comprises selection of genes encoding for protein kinases targeted by the said tyrosine kinase inhibitor, for each one of these genes, providing at least one nucleic acid probe which hybridizes to said gene under stringent conditions, thus providing an array of nucleic acid probes, having a biological sample containing cancer cells from said human or animal, extracting DNA from the sample, fragmenting into DNA fragments, optionally labeling the DNA fragments, submitting the optionally labeled DNA fragments to hybridization with the array of nucleic acid probes, recovering and quantifying for all the genes the gains or losses in gene copy numbers, wherein gains and losses of gene copy numbers of each selected gene are used to determine whether the tumor is sensitive or not to said kinase inhibitor.
