Frequencies of intratumoral CD39+ Treg in relation to clinical parameters. Frequencies of CD39+ Treg were determined by flow cytometry in cell suspensions isolated from colon tumors. Frequencies of CD39+ Treg among intratumoral Treg in relation to age (A), tumor localization (B), tumor differentiation grade (C), T stage (D), lymph node spread (E), and tumor stage (F). Symbols represent individual values and horizontal lines the median. Individual values are color-coded in red (group I) and blue (group II)
