  • Publication number: 20090298061
    Abstract: Described are 12 human genes which are differentially expressed in neoplastic tissues of patients responding well to treatment as compared to patients not responding well as determined by overall survival time in the non responding cohort. Moreover, methods for prognosis of the therapeutic success in cancer therapy are described. These methods are based on determination of expression levels of particular genes which are differentially expressed in cancer patients, preferably the genes encoding VEGFC, ERBB3 and Her2/neu, prior to the onset of anti-cancer chemotherapy. These methods are particularly useful in the investigation of advanced head and neck cancer, but are useful in the investigation of other types of cancer and therapies as well.
