FASLG and neoplasm: Significantly, there were consistently two-fold more apoptotic TILs within tumour nests that expressed FasL relative to those nests that did not (Figure 3B) (range 1.6–2.5-fold, n=14, P<0.001; Wilcoxon signed rank) (n=14; two of the 16 tumours did not contain sufficient FasL-negative nests to reach a count of 500 TILs).
