In line with visual observations, quantitative evaluations of three regions of interest revealed the CD68-positive cells at the tumor – liver border ranging from 2% to 24% (median 5%), within the liver tissue around the portal veins ranging from 1% to 18% (median 3%), and within distant liver tissue ranging from 1% to 10% (median 3%); analysis was performed for panel I and II in combination. Here, CD68 is linked to neoplasm.
