Tumor volume and pO2 do not correlate with one another. a Mean tumor volume ± SEM of tumors from mice treated for 4 days with vehicle (white bars) or 100 mg/kg imatinib (grey bars). a Mean tumor volume ± SEM of tumors from mice treated for 4 days with vehicle (white bars) or 100 mg/kg STI571 (grey bars). The numbers of analyzed tumors in vehicle and imatinib treatment groups, respectively, were KAT-4 (5 and 5), CT-26 (9 and 8) and B16BB (5 and 5). Tumor volume and pO2 were plotted for individual KAT-4 (b), CT-26 (c) and B16BB (d) tumors. The p-values for Spearman rank-order correlation coefficients (ρ), are given
