Circulating tumor DNA indicates increased risk of relapse after stem cell transplant in patients with diffuse large B-cell lymphoma

Many patients with diffuse large B-cell lymphoma (DLBCL) can be cured by a transplant using their own blood-forming stem cells, but as many as half eventually relapse. New research led by Dana-Farber Cancer Institute scientists suggests that patients whose blood or stem cell samples harbor tumor DNA are likely to relapse.
