Intervention trial. Effect of treatment on (A) the mean tumor volume (mm3) +/- standard deviation and (B) mean tumor number +/- standard deviation in 10 week old RIP1-Tag2 mice with small solid tumors for n = 8–11 mice. IT10w stands for initial tumor burden and tumor number. Statistical analysis was done using a two-tailed, unpaired Mann-Whitney test. P values comparing experimental groups to untreated control mice are 0.03 , 0.0004 , and 0.0044 , respectively. P value comparing 600R treated mice to TCR+600R is 0.0055 .
