FDG-PET/CT in Lymphoma: Staging, Deauville Scoring, and Prognostic Biomarkers

FDG-PET/CT is central to lymphoma management: Lugano staging, Deauville response assessment, and total metabolic tumor volume as a powerful prognostic biomarker. In Hodgkin lymphoma, interim PET guides treatment de-escalation; in DLBCL, it is prognostic but not yet actionable. P…

• Total metabolic tumor volume (TMTV) is an independent prognostic biomarker across lymphoma subtypes.
• Interim PET in DLBCL remains prognostic but currently does not guide therapy decisions.
• Emerging PET radiomics and deep learning approaches require standardization before clinical adoption.
