N2 - In a time of increasing treatment options for multiple myeloma bone disease, risk factors predicting progression need to be elucidated. This study investigated the value of serum YKL-40, previously shown to be associated with radiographic progression of bone destruction, as a predictor for time to clinical progression, i.e. skeletal-related events (SREs), in 230 newly diagnosed patients with multiple myeloma receiving intravenous bisphosphonates. Serum concentrations of YKL-40 and biochemical bone markers (CTX-MMP, CTX-I, PINP) were measured at diagnosis. Patients were evaluated every third month for SRE and at 9 and 24 months for radiographic progression. Elevated serum YKL-40 was seen in 47% of patients and associated with high-risk disease (International Staging System stage III; p < 0.001), increased bone resorption (serum CTX/MMP; p < 0.001) and early radiographic progression at 9 months (p = 0.01). Serum YKL-40 together with serum CTX-MMP/PINP ratio and World Health Organization status were independent predictors of time to first SRE.
