IL6 and ovarian cancer: It is thus possible that in analogy to what has recently been shown in ovarian cancer (Mor et al, 2005), the simultaneous evaluation of multiple markers such as SAA, hK6, hK10, and IL-6 by a multiplex, bead-based immunoassay system may ultimately allow the development of a test endowed with high specificity and sensitivity for the detection of USPC.
