At the time of tracer administration there was no significant difference in tumor volume between any of the experimental groups (Figure 1B, left panel); however, at the time of imaging on day 11 post-inoculation, tumor volumes were significantly lower in mice receiving ICI treatment (p<0.0001 for IFNγ, p=0.0018 for IgG, Figure 1B, right panel). This evidence concerns the gene IFNG and neoplasm.
