Traditionally, AML patients are treated with first-line chemotherapy drugs. If they fail, patients are classified as having a more severe and difficult-to-treat disease, and are then given a more aggressive therapy, like a bone marrow transplant. Being able to tell which patients are most likely to fail standard treatments could lead to the administration of more precise therapies at the outset of treatment.
They also concluded that a set of 15-gene DNA methylation biomarker was highly predictive of overall patient survival. "The findings have the potential to tell physicians whether or not a patient has a relatively easy or difficult disease to treat, and tailor a patient's therapy accordingly," explains Dr. Melnick. "This saves time trying therapies that will eventually prove to have no effect."
In addition, the investigators discovered a set of 45 genes that are almost universally methylated in AML patients. Methylation of these genes was far more common than any genetic mutation associated with AML, and could provide new ways to more effectively therapeutically target AML in the future.
"Investigators from the Sackler Center at Weill Cornell are leaders in the field of decoding epigenetic information from human tumors and ascertaining their clinical impact," says Dr. Andrew I. Schafer, chairman of the Department of Medicine at NewYork-Presbyterian Hospital/Weill Cornell Medical College. "Such findings will lead to the development of new therapies that give hope to cancer patients who are now without effective treatment."
