Abstract
The present study is to investigate whether extranodal (EN) metabolic tumor volume (MTV) would have a specific clinical meaning for survival in EN diffuse large B cell lymphoma (DLBCL) patients. Two hundred forty DLBCL patients with EN involvement received 18F-fluorodeoxygenase (FDG) positron emission tomography/computed tomography (PET/CT) were enrolled. Survival analysis revealed that low EN MTV (PFS [progression-free survival], HR = 0.278, 95% CI = 0.127–0.807, p = 0.001; OS [overall survival], HR = 0.320, 95% CI = 0.145–0.703, p = 0.003), low total MTV (PFS, HR = 0.194, 95% CI = 0.085–0.445, p < 0.001; OS, HR = 0.213, 95% CI = 0.092–0.491, p < 0.007), and high National Cancer Center Network-International Prognostic Index score (PFS, HR = 3.152, 95% CI = 1.732–5.734, p < 0.001; OS, HR = 2.457, 95% CI = 1.363–4.430, p = 0.003) were independently associated with survivals in the patients. Our data showed that EN MTV is a useful and novel prognostic parameter for predicting survival in DLBCL patients with EN involvement.
