Abstract

Over the past two decades, next-generation sequencing (NGS) has revolutionized our understanding of the pathogenesis of myeloid neoplasms (MNs) and their clinical management. While traditional Sanger sequencing allows for the interrogation of single loci, NGS enables the parallel sequencing of multiple genomic locations, ranging from targeted sets of genes to the entire genome. Initially, NGS was used predominantly in research, where the ability to interrogate large regions of the genome facilitated the discovery of genes recurrently mutated in myeloid malignancies. Soon thereafter, NGS entered the clinical realm where it is now routinely utilized in diagnosis, prognostication and treatment decision-making. However, the broad availability of clinical NGS comes with a unique set of challenges. Hematologists must interpret complex molecular reports and appropriately apply the provided mutational information to their patients’ care in real-time. Consequently, a systematic approach to interpreting NGS reports is crucial; the following will outline one such framework.

Author Biography

James A. Kennedy, MD, PhD, FRCPC

Dr. James Kennedy is a Malignant Hematologist at Sunnybrook Health Sciences Centre and Assistant Professor at the University of Toronto. He completed the combined MD/PhD program in Toronto, where his graduate research focused on developing experimental models of hematologic malignancies. Building on this background, he subsequently completed residency training in Internal Medicine and Hematology, also at the University of Toronto, then enrolled in a combined clinical/research malignant hematology fellowship, splitting time between the Princess Margaret Cancer Centre and Brigham & Women’s Hospital / Harvard Medical School. From a research standpoint, James is interested in understanding the genetic events that drive the leukemogenic process and how these can be targeted therapeutically. His clinical focus at Sunnybrook Health Sciences Centre encompasses acute leukemia, bone marrow failure and chronic myeloid malignancies.
