Immune suppression is a hallmark of multiple myeloma (MM), but data on soluble factors involved in the fate of immune effector cells are limited. The CXCR3-binding chemokine monokine induced by interferon-gamma (MIG/CXCL9) has been associated with tumor progression, immune escape, and angiogenesis in several malignancies. We here aimed to evaluate the prognostic relevance of MIG in MM. MIG serum levels were significantly elevated in newly diagnosed MM patients (n = 105) compared to patients with monoclonal gammopathy of undetermined significance (MGUS; n = 17) and healthy controls (n = 37). MIG expression in stromal compartments but not purified MM cells correlated with serum levels. High MIG serum levels were significantly associated with established prognostic markers (international staging system: R=0.25, p = 0.001; age: R=0.47, p < 0.0001; lactate dehydrogenase: R=0.34, p = 0.0005) and poor overall survival (OS) (median OS 17.0 months vs. not reached, p<0.001). A similar association was found for CXCL10 and CXCL11. Multivariate regression analysis indicated MIG as an independent prognostic factor of OS.
