Examples of Results of Testing for Mutations at Diagnosis and on the Bone Marrow Obtained About Day 30 After the Start of Induction Chemotherapy. At diagnosis, the listed mutations are examples of those seen in some of the patients. The column “Day 30” illustrates whether those mutations were detected (POS, positive) or not detected (NEG, negative) at the time the bone marrow was obtained, at about day 30. The patients with mutations that were still present at day 30 exhibited worse EFS and OS compared with those that cleared the mutations.
