This retrospective study aimed to investigate the combined prognostic values of intratumoral metabolic heterogeneity (MH), disseminate feature (Dmax) and total metabolic tumor volume (TMTV) by 2-deoxy-2-\[18F\]fluoro-D-glucose positron emission tomography/computed tomography (\[18F\]FDG PET/CT), and establish novel nomograms to improve prognosis prediction in diffuse large B-cell lymphoma (DLBCL)
This retrospective study aimed to investigate the combined prognostic values of intratumoral metabolic heterogeneity (MH), disseminate feature (Dmax) and total metabolic tumor volume (TMTV) by 2-deoxy-2-\[18F\]fluoro-D-glucose positron emission tomography/computed tomography (\[18F\]FDG PET/CT), and establish novel nomograms to improve prognosis prediction in diffuse large B-cell lymphoma (DLBCL) Patients would be retrospectively includedin this study.The inclusion criteria included (1) pathologically proven DLBCL; (2) first-line treatment with R-CHOP or R-CHOP-like chemotherapy including R-miniCHOP and R-ECHOP (rituximab, etoposide, prednisone, vincristine, cyclophosphamide, and doxorubicin); (3) at least 2 evaluable hypermetabolic lesions on PET/CT;(4) underwent pre-treatment \[18F\]FDG PET/CT.
