The percentage of CD11b+Gr-1+ MDSCs and CD11b+Gr-1−F4/80−MHC-II− e-MDSCs significantly correlated with tumor volumes, i.e., the in situ sites that were infiltrated by higher numbers of CD11b+Gr-1+ MDSCs or CD11b+Gr-1−F4/80−MHC-II− e-MDSCs showed larger tumor sizes (R2 = 0.1480 vs. R2 = 0.4491, P = 0.0205, P < 0.001, Figure 3E) and more metastatic lung nodules (R2 = 0.1342 vs. R2 = 0.3587 P = 0.0280, P = 0.0001, Figure 3F). The gene discussed is ITGAM; the disease is neoplasm.
