18F-FDG PET/CT-based Prognostic Model for Predicting Outcome in Patients With Natural Killer/T-cell Lymphoma
18F-FDG PET/CT-based Prognostic Model for Predicting Outcome in Patients With Natural Killer/T-cell Lymphoma
The purpose of this study is to evaluate whether 18F-FDG PET/CT-based prognostic model of
 NK/T-cell lymphoma can predict disease progression
In this study investigators develop a prognostic model based on 18F-FDG PET/CT and test its
 ability for prognostic value in patients with DLBCL. PET/ CT scans evaluation using the liver
 SUVmax as reference. Positive lesions in PET were indicated as SUVmax of residues higher than
 the threshold or new 18F-FDG avid lesions. 18F-FDG PET/CT-based prognostic model includes
 PET/CT image, dominant clinical and pathological prognostic factors to predicting disease
 progression during chemotherapy or survival in NK/T-cell lymphoma.
