The present invention provides diagnostic methods for assessing the EMT status of tumor cells, and for predicting the effectiveness of treatment of a cancer patient with an EGFR or IGF-1R kinase inhibitor, utilizing an EMT gene signature index score. The present invention further provides methods for treating patients with cancer that incorporate these methods. 148-. (canceled)49. A method of determining the EMT status of tumor cells , comprising:measuring in a sample of the tumor cells the relative expression level of each gene of an EMT gene signature (EMTGS), wherein the EMTGS consists essentially of the following genes:SERPINA3, ACTN1, AGR2, AKAP12, ALCAM, AP1M2, AXL, BSPRY, CCL2, CDH1, CDH2, CEP170, CLDN3, CLDN4, CNN3, CYP4X1, DNMT3A, DSG3, DSP, EFNB2, EHF, ELF3, ELF5, ERBB3, ETV5, FLRT3, FOSB, FOSL1, FOXC1, FXYD5, GPD1L, HMGA1, HMGA2, HOPX, IFI16, IGFBP2, IHH, IKBIP, IL-11, IL-18, IL6, IL8, ITGA5, ITGB3, LAMB1, LCN2, MAP7, MB, MMP7, MMP9, MPZL2, MSLN, MTA3, MTSS1, OCLN, PCOLCE2, PECAM1, PLAUR, PLXNB1, PPL, PPP1R9A, RASSF8, SCNN1A, SERPINB2, SERPINE1, SFRP1, SH3YL1, SLC27A2, SMAD7, SNAIL SNAI2, SPARC, SPDEF, SRPX, STAT5A, TBX2, TJP3, TMEM125, TMEM45B, TWIST1, VCAN, VIM, VWF, XBP1, YBX1, ZBTB10, ZEB1, ZEB2;calculating an EMTGS index score for said tumor cells by applying an algorithm to the measured expression level values that incorporates the contributions of co-correlated genes; anddetermining if said EMTGS index score is more similar to an EMTGS index score from a reference epithelial tumor cell or an EMTGS index score from a reference mesenchymal-like tumor cell, and thus determining the EMT status of the sample tumor cells.50. The method of claim 49 , wherein the tumor cells are NSCL cancer claim 49 , breast cancer claim 49 , colorectal cancer claim 49 , or pancreatic cancer tumor cells.51. A method of identifying a human tumor as likely to be responsive or non-responsive to treatment with an EGFR kinase inhibitor claim 49 , comprising:measuring in a ...
