Abstract: Disclosed is a method for characterization, in a biological sample, of circulating tumour cells (CTCs) bearing at least one marker characteristic of the tumorous nature of the cell, the marker being selected from the groups constituted by: the oncogenic proteins characteristic of the CTCs, and the tumour markers. Also disclosed is the use of this method for deciding on the implementation of a treatment for a cancer patient.

Abstract: Disclosed is a method for characterization, in a biological sample, of circulating tumour cells (CTCs) bearing at least one marker characteristic of the tumorous nature of the cell, the marker being selected from the groups constituted by: the oncogenic proteins characteristic of the CTCs, with the exception of the proteins encoded by the EML4-ALK fusion gene, and the tumour markers. Also disclosed is the use of this method for deciding on the implementation of a treatment for a cancer patient.

Abstract: A method for determining the benign or malignant state of a breast tumor in a biological sample is presented. The benign or malignant state is determined by measuring the variation of expression of twelve genes and at least one variant of each of the twelve genes when the variants exist, using a combination of 50 polynucleotide probe sets. An expression profile of the sample is then compared with reference expression profiles of control benign and malignant breast tissues. The probe sets can be arranged in a microarray.

Abstract: The invention relates to the use of a multiplicity of polynucleotide probe sets, the multiplicity of polynucleotide probe sets consisting in a combination of pools of polynucleotide probe sets, each polynucleotide probe set containing at least one polynucleotide probe chosen among a library of nucleic acid sequences, the polynucleotide probes involved in the combination of pools of polynucleotide probe sets of the multiplicity of polynucleotide probe sets being such that each polynucleotide probe specifically hybridizes with one gene, and/or at least one of its variants when present, for determining the variation of expression at least 12 genes, and their variants when present, in order to diagnose the benign or malignant state of a breast tumor.

Abstract: A method for assessing the proliferative state of cells in a human or non-human biological sample uses Chromatin Assembly Factor-1 (CAF-1) subunits as proliferation markers. The method can be used for breast cancer prognosis or diagnosis, and monitoring tumor response in therapy.

Abstract: The invention relates to a method for assessing the proliferative state of cells in a human or non human biological sample, comprising using Chromatin Assembly Factor-1 (CAF-1 in short) subunits as proliferation markers. Application for cancer prognosis or diagnosis and monitoring tumor response in therapy.

Abstract: The invention concerns a method for detecting intrachromosome imbalance in interphase nuclei, characterised in that it consists in: (a) hybridising in situ the chromosome suspected to be affected by said imbalance using two probes marked with different fluorochromes and specific of said chromosome long arm and short arm respectively; (b) measuring the intensity of the fluorescence emitted in said nuclei with different emission wavelengths corresponding to each of the two fluorochromes; (c) calculating the ratio (Ra) between the two measured values of fluorescence intensity; and (d) comparing the resulting ratio value with at least one reference value. The invention also concerns a kit for implementing said method and uses of said kit and said method, in particular for detecting cancer cells in a biological sample and for diagnosing cancer pathologies.
