<p>A method for assessment of a number or density of immune cells in tumoral tissues comprising the steps consisting in: a. providing one or more immunostained slices of tissue section obtained by an automated slide-staining system by using antibodies binding specifically to antigens (markers) expressed by immune cells. b. proceeding to digitalisation of the slides of step a. by high resolution scan capture, whereby a high definition (4.6μm/pixel or better) digital picture of the slide to be analysed is obtained, c. detecting the slice of tissue section on the digital picture d. analyzing the slice of tissue section for defining (i) the tumour (CT) and (ii) the invasive margin of the tumour (IM), e. providing a size reference grid with uniformly distributed units having a same surface, said grid being adapted to the size of the tumour to be analyzed, e1. checking the quality of immunostaining, f. detecting and quantifying stained cells of each unit whereby the number or the density of immune cells stained of each unit is assessed.</p> |
