[Prognostic value of pretreatment (18)F-FDG PET-CT metabolic parameters in patients with advanced extranodal NK/T cell lymphoma].
Objective: To investigate the prognostic values of the maximum standardized uptake value (SUV(max)), metabolic tumor volume (MTV) and total lesion glycolysis (TLG) calculated from pretreatment (18)F-fluorodeoxy glucose ((18)F-FDG) PET-CT results of patients with advanced extranodal NK/T cell lymphoma (ENKTL). Methods: The clinic data, follow-up data and pretreatment (18)F-FDG PET-CT data of 45 patients with ENKTL of stage Ⅳ were collected. The optimal cutoff value of progression-free survival (PFS) of SUV(max), MTV and TLG were analyzed by using receiver-operating characteristic (ROC) curve. ⋯ Multivariate analysis showed that KPI, MTV and TLG were independent prognostic predictors of PFS and OS (all P<0.05). Conclusions: MTV and TLG of pretreatment (18)F-FDG PET-CT are independent prognostic factors for PFS and OS of patients with advanced ENKTL. MTV and TLG may be more fit for evaluating the prognosis of ENKTL patients than SUV(max).
