Description:
The pathologist of each center will choose a tumor block containing the core of the tumor and the invasive margin. Three tissue sections of 4 microns of this tumor block will be cut and deposited on glass slides for the immunohistochemical analyses. Four tissue sections of 4 microns will be cut and deposited in a safe lock eppendorf tube for a DNA extraction. If biopsies for diagnostic purpose are available in the laboratory of pathology for the same patient, one tissue section of 4 microns of each biopsy will be cut and deposited on a glass slide
