CCL22 and ovarian carcinoma: It has been reported that production of the chemokine CCL22 is associated with human ovarian cancer (Iellem et al., 2001; Curiel et al., 2004) and has also been observed in other types of malignancies, such as gastric cancer (Haas et al., 2008, 2009), Hodgkin’s lymphoma (Ishida et al., 2006), and breast cancer (Menetrier-Caux et al., 2009).
