SLFN11 and colorectal cancer: SLFN11 expression was low or absent in patients 28 and 36 with colorectal cancer (nuclear SLFN11 H-scores of 0 and 32, respectively), as well as patients 31 and 33 with ovarian cancer (nuclear SLFN11 H-scores of 23 and 33, respectively), which is consistent with recent analysis of over 6,600 patient tumor biopsies [41].
