Our previous study of inflammation in the context of myeloma and its asymptomatic stage (MGUS) revealed that except for four cytokines found to be significantly higher in myeloma (HGF, IL-11, RANTES, SDF-1α), the levels of 38 inflammation cytokines were similar in MGUS and in myeloma [45]. The gene discussed is HGF; the disease is plasma cell myeloma.
