Relapsed Acute Lymphoblastic Leukemia (ALL): Mutational Landscape

Multi-agent combination chemotherapy can be curative in acute lymphoblastic leukemia (ALL). Still, patients with primary refractory disease or those with relapsed leukemia have a very poor prognosis. Here we report the mutational landscape of matched diagnostic and relapsed pediatric and adult ALL samples. Our data provides comprehensive annotation of genetic lesions acquired at relapse and reveals diagnostic and relapse-specific mutational mechanisms in ALL.]]> Patients who have had samples collected at diagnosis, remission, and relapse were included.]]>
