846P Predictive and prognostic values of serum VEGF in patients with multiple myelomas receiving bortezomib-based therapy

Abstract

Conclusions: These results suggest that in this cohort of r/r patients, SPM IR increases with age and that most of the SPMs are solid tumours. To our knowledge, this is one of the first studies that uses real-world data to estimate a population-level background incidence for SPMs in r/r NHL and MM patients, regardless of therapy received.
