The present invention relates to a method for predicting the evolution of a solid tumours in an individual, comprising at least the following steps: a) form a virtual blade from a sample of the tumor, on which an edge of the tumor is identifiable, b) quantify on said blade virtual carried out in step a) the density of the cells and / or in the blood vessels present in a continuous zone covering the edge of the tumor and extending on either side of the edge of the tumor over a distance at least equal to 0.5 mm, called "quantization zone ", and c) can be deduced from said quantification the risk of relapse patients post-operatively, and / or the sensitivity to the various treatments anti - tumour and / or the risk of hepatic metastases in the patient. Preferably, the cells to quantify are white blood cells, such as t lymphocytes, the b lymphocytes and macrophages and nk cells, dendritic cells, or under - populations of the immune cells.
