The present invention provides sets of genes the expression of which is important in the prognosis of cancer. In particular, the invention provides gene expression information useful for predicting whether cancer patients are likely to have a beneficial treatment response to chemotherapy.

Gene expression markers for predicting response to chemotherapy

The present invention concerns prognostic markers associated with cancer. In particular, the invention concerns prognostic methods based on the molecular characterization of gene expression in paraffin-embedded, fixed samples of cancer tissue, which allow a physician to predict whether a patient is likely to respond well to treatment with an EGFR inhibitor.

Gene expression markers for response to egfr inhibitor drugs

The present invention provides diagnostic and prognostic methods for predicting the effectiveness of treatment of a cancer patient with an EGFR kinase inhibitor. Methods are provided for predicting the sensitivity of tumor cell growth to inhibition by an EGFR kinase inhibitor, comprising assessing whether the tumor cell has undergone an epithelial to mesenchymal transition (EMT), by determining the expression level of epithelial and/or mesenchymal biomarkers, wherein tumor cells that have undergone an EMT are substantially less sensitive to inhibition by EGFR kinase inhibitors. Improved methods for treating cancer patients with EGFR kinase inhibitors that incorporate the above methodology are also provided. Additionally, methods are provided for the identification of new biomarkers that are predictive of responsiveness of tumors to EGFR kinase inhibitors. Furthermore, methods for the identification of agents that restore the sensitivity of tumor cells that have undergone EMT to inhibition by EGFR kinase inhibitors are also provided.

Biological markers predictive of anti-cancer response to epidermal growth factor receptor kinase inhibitors

The present invention provides diagnostic and prognostic methods for predicting the effectiveness of treatment of a cancer patient with an IGF-1R kinase inhibitor. Methods are provided for predicting the sensitivity of tumor cell growth to inhibition by an IGF-1R kinase inhibitor, comprising assessing whether the tumor cell has undergone an epithelial to mesenchymal transition (EMT), by determining the expression level of epithelial and/or mesenchymal biomarkers, wherein tumor cells that have undergone an EMT are substantially less sensitive to inhibition by IGF-1R kinase inhibitors. Improved methods for treating cancer patients with IGF-1R kinase inhibitors that incorporate the above methodology are also provided. Additionally, methods are provided for the identification of new biomarkers that are predictive of responsiveness of tumors to IGF-1R kinase inhibitors. Furthermore, methods for the identification of agents that restore the sensitivity of tumor cells that have undergone EMT to inhibition by IGF-1R kinase inhibitors are also provided. pErk, HER3 and pHER are also demonstrated to be effective biomarkers for predicting sensitivity of tumor cells to IGF-1R kinase inhibitors.

Biological markers predictive of anti-cancer response to insulin-like growth factor-1 receptor kinase inhibitors

Certain embodiments provide a method for capturing a genomic fragment. The method may comprise: obtaining a substrate comprising a first population of surface-bound oligonucleotides and a second population of surface-bound oligonucleotides; hybridizing a first member of the first population of surface-bound oligonucleotides to a selection oligonucleotide comprising a region that hybridizes with the first member and a region that contains a genomic sequence; extending the first member of the first population of surface-bound oligonucleotides to produce a support-bound selection primer that comprises a sequence that is complementary to the genomic sequence; hybridizing the support-bound selection primer to a nucleic acid fragment comprising the genomic sequence; extending the support-bound selection primer to produce an extension product that contains a sequence that flanks the genomic sequence, e.g., in a genome; and amplifying the extension product on the substrate.

Direct capture, amplification and sequencing of target dna using immobilized primers

The present invention concerns prognostic markers associated with EGFR positive cancer. In particular, the invention concerns prognostic methods based on the molecular characterization of gene expression in paraffin-embedded, fixed tissue samples of EGFR-expressing cancer, which allow a physician to predict whether a patient is likely to respond well to treatment with an EGFR inhibitor.

Gene expression profiling of egfr positive cancer

La presente invention a trait a des marqueurs de pronostic associes au cancer a recepteur de facteur de croissance epidermique. En particulier, l'invention a trait a des procedes de pronostic bases sur la caracterisation moleculaire de l'expression genetique dans des echantillons tissulaires de cancer d'expression de recepteur de facteur de croissance epidermique inclus dans la paraffine, qui permettent au physicien de predire si le patient est susceptible d'une reaction appropriee a un traitement realise avec un inhibiteur du recepteur de facteur de croissance epidermique.
