PTPRC and carcinoma: Following this, we compared the percent of TILs with the expression of selected markers on cells negative for CD45 and found samples of pre-invasive carcinoma and stage IA carcinoma displayed moderately strong negative correlation between the percentage of TILs and the abundance of FLT4 (+) or MET (+) tumor cells (FLT4: r = −0.672 at p = 0.017, R^2 = 45.19, MET: r = −0.516 at p = 0.085, R^2 = 26.65, ANOVA); by contrast, the frequency of SLUG(+) cells was positively correlated with the percentage of TILs (r = 0.660 at p = 0.019, R^2 = 43.61, ANOVA).
