Abstract: The present invention relates to a method of predicting the therapeutic response of a drug directed towards a cancer in a human patient using samples of blood cells taken from the patient at different times. The method comprises the steps of culturing cells from the samples in a suitable medium; adding a stimulator of proliferation and an immuno-modulating drug of the cells to the culture; and assaying the proliferation of the cells in the culture; comparing the assay of proliferation with a previously made analysis demonstrating correlation between the proliferation of the cells and parameters of the therapeutic response of the drug in the human patient.

Abstract: The present invention relates to a method of predicting the therapeutic response of a drug against a malignant tumour in a human patient, using a sample of a fine needle aspirate of the tumour from the patient. The method comprises the steps of identifying and estimating in the sample the number of cells belonging to one class of cells in relation to other cells in the sample, and comparing the estimation with a previously made analysis demonstrating correlation between the number of cells and parameters of the therapeutic response of the drug directed towards the tumour in human patients, the results of the comparison being indicative of the therapeutic response of the drug in human patient.
