Irene Roberts, MD, of Oxford’s Weatherall Institute of Molecular Medicine, discusses children with Down syndrome, who have a more than 100-fold increased risk of developing acute myeloid leukemia before their fourth birthday compared to children without Down syndrome. Their risk of acute lymphoblastic leukemia is also increased by around 30-fold. Dr. Roberts details current knowledge about the biologic and molecular basis of this relationship between leukemia and Down syndrome, the role of trisomy 21 in leukemogenesis, and the clinical implications of these findings.
Jiye Liu, PhD, of Dana-Farber Cancer Institute, discusses study findings that demonstrate KDM6A regulates CD38 and CD48 expression in multiple myeloma. Dr. Liu’s team validated combination treatment with an FDA-approved EZH2 inhibitor plus daratumumab, which can overcome daratumumab resistance in preclinical multiple myeloma models, providing the rationale for combination clinical trials to improve patient outcome (Abstract 148).
Francesco Maura, MD, of the University of Miami, Sylvester Comprehensive Cancer Center, discusses his team’s findings in which they defined a comprehensive catalogue of genomic determinants of response to DKRd (carfilzomib, lenalidomide, dexamethasone) in newly diagnosed multiple myeloma.

Researchers from The University of Texas MD Anderson Cancer Center showed that inhibiting menin with an oral small-molecule inhibitor of the menin-KMT2A interaction, SNDX-5613—now named revumenib—yielded encouraging responses for patients with advanced acute leukemias and KMT2A rearrangements or...
Stephen M. Ansell, MD, PhD, and Patrizia Mondello, MD, PhD, both of the Mayo Clinic, discuss the 20% of patients with follicular lymphoma (FL) who relapse early and experience a poor prognosis. The researchers found that FLs with high levels of IRF4 expression are associated with a suppressive tumor microenvironment, and selective IRF4 silencing restores antilymphoma T-cell immunity. Further investigation is warranted to identify the mechanisms by which IRF4 controls tumor immunity to develop precision therapies for this population (Abstract 70).
Patients with invasive breast cancer who had low scores on an investigational gene molecular signature had similar rates of local recurrence independent of whether they received adjuvant radiation therapy after breast-conserving surgery, according to findings presented by Karlsson et al at the 2022 ...
My father was diagnosed with prostate cancer in 1994, when he was just 55 years old. He died 6 years later. The cancer was so aggressive, it took only a few weeks from the time he was diagnosed for the cancer to grow to the size of a softball, and even a radical prostatectomy couldn’t save his...
