CCR2 and neoplasm: SBRT followed by αPD-1 alone, CCR2/5i alone, or αPD-1 + CCR2/5i suppressed tumor growth in only some of the mice, and SBRT followed by αPD-1 + CCR2/5i + GVAX suppressed tumor growth in all the mice initially up to approximately day 33 (i.e., 33 d from orthotopic tumor implantation; Fig. S3 C).
