Frequencies of M2-like macrophages and MDSCs increased after treatment among the patients in CR group but decreased in PR + NR group. Differences in M2-like macrophages among the CR group (n = 22) (a) and among PR + NR group (n = 11) (c); changes in the circulating MDSCs among the CR group (b) and among PR + NR group (d) monitored before and after treatment. Data analyzed by paired Student’s t test
