The numbers of CD68 + macrophages, MAC387 + macrophages, and CLEVER-1/Stabilin-1 + macrophages and vessels were scored from three hotspots (areas with the most macrophages by eye) intratumorally and peritumorally with a 0.0625 mm 2 grid using 40× magnification when scoring macrophages and 20× when scoring lymphatic/blood vessels.
