“…Importantly, increased levels of IL-1Ra were observed in numerous malignancies, including colorectal cancer (Iwagaki et al, 1997;Ito and Miki, 1999;Kaminska et al, 2000), multiple myeloma (Gherardi et al, 1996), ovarian cancer (Mustea et al, 2008), leukemia (Barak et al, 1998), cervical carcinoma (Fujiwaki et al, 2003), pancreatic cancer (Ebrahimi et al, 2004;Poch et al, 2007), uveal melanoma (Lee et al, 2012), prostate cancer (Parekh et al, 2007), breast cancer (Lv et al, 2011), and thyroid cancer (Niedźwiecki et al, 2008). It is interesting that elevated concentrations of IL-1Ra were associated either with greater (Iwagaki et al, 1997;Ito and Miki, 1999;Kaminska et al, 2000;Fujiwaki et al, 2003;Parekh et al, 2007;Niedźwiecki et al, 2008) or lesser (Gherardi et al, 1996;Parekh et al, 2007;Poch et al, 2007) disease severity.…”
