  • Publication number: 20160355889
    Abstract: The present invention is related to a method of classifying a sample of a patient who suffers from or being at risk of developing cancer, said method comprising the steps of determining in said sample from said patient, on a non protein basis, the expression level of at least one gene encoding for a hormone receptor selected from the group comprising estrogen receptor, progesterone receptor and/or androgen receptor in said sample; comparing the one or more expression level(s) determined with one or more expression level(s) of one or more reference genes, and classifying the sample of said patient from the outcome of the comparison into one of at least two classifications.

  • Publication number: 20120015827
    Abstract: The present invention is related to a method for predicting a clinical response of a patient suffering from or at risk of developing a neoplastic disease towards a given mode of treatment, said method comprising the steps of: a) obtaining a biological sample from said patient; b) determining, on a non protein basis, the expression level of at least one gene encoding for a ligand from the Vascular endothelial growth factor (VEGF) family and of and of at least one gene encoding for a receptor from the ErbB-family, or a gene co-expressed therewith, in said sample, c) comparing the pattern of expression levels determined in (b) with one or several reference pattern (s) of expression levels; and d) predicting therapeutic success for said given mode of treatment in said patient or implementing therapeutic regimen targeting the signalling pathway of said ligand and/or receptor is related to in said patient from the outcome of the comparison in step (c).

  • Publication number: 20100099108
    Abstract: A method for detecting or isolating disease-associated cells or pluripotent stem cells from body samples is provided where cells of a body sample are transfected with nucleic acid constructs that include the following components: (a) a promoter element containing at least one DNA site for binding one or more transcription factors; and (b) a reporter gene that enables the diseased or stem cells to be detected. When the method is used for detecting disease-associated cells, the transcription factor initiates at least one signalling activity in the disease-associated cells that is not present in healthy cells.

  • Publication number: 20090150315
    Abstract: In one embodiment, the invention provides methods for predicting a clinical outcome of a patient's neoplastic disease comprising: (a) determining a predictor value algorithmically using patient sample values for (1) at least one tumor marker or at least one immune marker, and (2) at least one marker that is (i) an extracellular matrix (ECM) marker (ii) a marker that is indicative of extracellular matrix synthesis (fibrogenesis), or (iii) a marker that is indicative of extracellular matrix degradation (fibrolysis); and (b) predicting the clinical outcome of the neoplastic disease by evaluating the predictor value.
