Dynamic risk assessment based on positron emission tomography scanning in diffuse large B-cell lymphoma: Post-hoc analysis from the PETAL trial.

•All IPI factors except age are surrogates of tumor burden that can be more accurately displayed by TMTV.•TMTV and iPET response predict TTP, PFS, and OS.•Combining TMTV and iPET response optimizes outcome prediction in DLBCL.
