Researchers discover mutations linked to relapse of childhood leukemia
Date:2/3/2013

ves. All seven patients with NT5C2 mutations relapsed within three years of the initial diagnosisan early, particularly hard-to-treat re-emergence likely mediated by the drug resistance.

Armed with the new knowledge, Dr. Carroll says doctors may be better equipped to identify patients likely to relapse. "We plan to test the feasibility of screening patients during therapy using sophisticated sequencing technology to pick up low-level mutations in NT5C2 and other genes indicating that a mutant clone is growing," he says. His team is researching whether that advance warning could allow doctors to administer separate drugs to beat back the cancer cells, and is also working on a strategy to directly inhibit the mutant enzyme.
