CEACAM5-positive specimens according to immunohistochemistry are shown in the left-hand panels, while specimens expressing high levels of CEACAM5 are shown in the right-hand panels. A summary of the mean values of the normalized tumor responses is given in Additional file 1: Table S4. D HE stainings of one representative colon cancer specimen is given, together with the immunofluorescent staining against CD3 and CD68, counterstained with DAPI.
