Background:
Few clinical studies have clarified the prognostic factors that affect clinical outcomes for patients with relapsed or refractory diffuse large B-cell lymphoma (DLBCL) after immunochemotherapy.
Methods:
A total of 158 patients with relapsed or refractory DLBCL were enrolled. All patients underwent positron emission tomography/computed tomography (PET/CT) before and after salvage therapy. All enrolled patients previously received the ifosfamide, carboplatin, and etoposide regimen. Clinical outcomes were compared according to several factors (age ≥ 65 years, low age-adjusted International Prognostic Index [aa-IPI], maximum standardized uptake value [SUVmax] <6.0 on PET/CT, time to relapse ≥12 months, complete response after salvage therapy). A low aa-IPI, SUVmax <6.0, and time to relapse ≥ 12 months were independent prognostic factors for survival.
Results:
In univariate analysis and multivariate analysis, SUVmax below 6.0 (P<0.001 for progression-free survival (PFS), P<0.001 for overall survival (OS)) and low aa-IPI (P<0.001 for PFS, P<0.001 for OS) were independent prognostic factors associated with favorable outcome.
Conclusion:
The aa-IPI and initial SUVmax were powerful prognostic factors in patients with relapsed or refractory DLBCL.
