CD26+ positive cells were defined by >99th percentile of CD26 intensity stained with isotype control. For the tumor size, the largest tumor dimension was given. All patients underwent surgery for colorectal cancer, whereas for patients 6, 7, 8, and 9, surgery for both the primary and metastatic tumors were performed. For patients 1, 4, 10, and 11, metastatic disease was suspected or confirmed after the initial surgery. NA, not applicable.
