While it has been proposed that up to 23% of ovarian cancers have a chronic inflammatory component [31], it is notable that the relative importance of IL-6 and MIP-1α to other analytes in the 11-analyte classifier is low, reflected both by the calculated importance value, and the absence of IL-6 and MIP-1α in the 7-analyte classifier. Here, IL6 is linked to ovarian carcinoma.
