MYC and diffuse large B-cell lymphoma: We decided to analyse in an observational cohort study the relapses of patients with stage I(E) DLBCL focusing on (1) initial therapy (only R‐CHOP vs. combined modality treatment), (2) clinical characteristics and risk profile of the patient, (3) patterns of relapse, (4) if available the presence of MYC breaks, and (5) the final outcome after treatment.
