Time now for tumor mutational burden?

November 2018—Like a piece of so-called sticky music, cutoff numbers can persist in physicians’ minds outside of any real clinical value and, in the process, leave their laboratory colleagues mildly befuddled (not to mention searching for more useful cutoffs). Such a jingle is creeping into tumor mutational burden. Lauren Ritterhouse, MD, PhD, co-director of the clinical genomics laboratory at the University of Chicago, recalls early conversations about TMB at her institution. Amid discussions about how and when to implement the testing, one colleague announced to all assembled that the cutoff number should be 100.

Fresh incentive to look for Ph-like ALL

October 2018—Cheryl Willman, MD, could hardly believe her eyes. She and her colleagues at the University of New Mexico, working with collaborators from across the U.S. in the NCI TARGET Project, had submitted 100 cases of high-risk pediatric acute lymphoblastic leukemia to British Columbia’s Cancer Agency for RNA sequencing to figure out why patients were doing so poorly, despite treatment with intensive chemotherapy. Now the results were in. Dr. Willman, the Maurice and Marguerite Liberman distinguished chair in cancer research and UNM distinguished professor of pathology, vividly recalls the scene.
