Dr. David Spencer talks about a new method of genome sequencing for cancer care in the sequencing lab at the Genome Institute in St. Louis on Wednesday, March 10, 2021. Spencer is the lead author on a study being published in the New England Journal of Medicine. Spencer and his team at Washington University say that gene sequencing can finally be put into practice by helping determine the best course of treatment for patients with blood cancers. This is among the first studies to show that whole genome sequencing can be used in routine clinical practice; a feat that was, until recently, cost prohibitive.
