However, it is important to note that a variety of human tumours, including for example breast, colon and ovarian cancers, express CXCL9/10/11 or do so after chemotherapy (Denkert et al, 2010; Sistigu et al, 2014; Au et al, 2016; Bronger et al, 2016; Loi et al, 2016; Nagarsheth et al, 2017; Opzoomer et al, 2019). Here, CXCL9 is linked to ovarian carcinoma.
