Abstract: The present invention concerns a method to determine the gene expression profile on a sample previously obtained from a patient diagnosed for a liver tumor, comprising assaying the expression of a set of genes in this sample and determining the gene expression profile (signature). In a particular embodiment, said method enables to determine the grade of the liver tumor, such as hepatoblastoma (HB) or a hepatocellular carcinoma (HCC). The invention is also directed to kits comprising a plurality of pairs of primers or a plurality of probes specific for a set of genes, as well as to solid support or composition comprising a set of probes specific for a set of genes. These methods are useful to determine the grade of a liver tumor in a sample obtained from a patient, to determine the risk of developing metastasis and/or to define the therapeutic regimen to apply to a patient.

Abstract: The present invention provides the use of the biomarkers SSEA4 and/or ST3GAL2 for assessing the outcome for chemotherapeutic treatment of a cancer in an individual and methods thereof.

Abstract: The invention relates generally to the field of cancer prognosis and treatment. More particularly, the present invention relates to methods and compositions that utilize a particular panel of gene products (“biomarkers”) and their differential expression patterns (“expression signatures”), wherein the expression patterns correlate with responsiveness, or lack thereof, to chemotherapy treatment. The invention is based on the identification of a specific set of biomarkers that are differentially expressed in chemotherapy-treated tumors and which are useful in predicting the likelihood of a therapeutic response, including residual disease persistence and subsequent tumor recurrence in cancer patients receiving chemotherapy. The gene panel is also useful in designing specific adjuvant modalities with improved therapeutic efficiency. Also disclosed are methods for characterizing tumors according to expression of the biomarkers described herein.
