Researchers from the University of Michigan Rogel Cancer Center, studying the molecular landscape of over 500 patients with an aggressive form of multiple myeloma, discovered a prevalence of activated key oncogenic pathways in these patients, much more than previously thought. Upwards of 45–65% of NF-κB and RAS/MAPK pathways each had alterations. The study was published in Nature Communications.
Further, Arul Chinnaiyan, M.D., Ph.D., director of the Michigan Center for Translational Pathology, and his team found a link between mutations and RASopathies, a certain group of genetic syndromes, in patients with relapsed treatment-resistant multiple myeloma. This was the first observation of its kind.
The team compared the molecular makeup of patients with untreated multiple myeloma to those with the relapsed treatment-resistant version of the disease. Comparing these patients allowed researchers to describe drivers of the more aggressive form of multiple myeloma.
