- The study evaluated the prognostic value of interim FDG-PET in diffuse large B-cell lymphoma (DLBCL) using data from the CALGB 50303 clinical trial.
- It found that change in SUVmax (ΔSUVmax) between baseline and interim PET predicted overall survival, with 2-year survival rates of 68.8% for non-responders vs 93.8% for responders.
- Using the Deauville 5-point scale to interpret interim PET results also predicted progression-free and overall survival. However, ΔSUVmax may be a better imaging biomarker to guide clinical trial design using PET response-adapted therapy in DLBCL.
