High APRIL but not BAFF serum levels are associated with poor outcome in patients with follicular lymphoma.
Elevated B cell activation factor (BAFF) and a proliferation-inducing ligand (APRIL) serum levels have been reported to correlate with worse prognosis in B cell-derived malignancies. However, limited information exists regarding the prognostic significance of BAFF and APRIL serum levels in follicular lymphoma (FL). We measured BAFF and APRIL serum levels for 81 patients with newly diagnosed FL and 12 healthy controls. ⋯ A high APRIL serum level was also significantly associated with decreased PFS and OS in patients treated with non-rituximab regimens but not in patients treated with rituximab-containing regimens. The APRIL serum level remained an independent predictor for PFS and OS in multivariate analysis. APRIL may be an important prognostic predictor with potential significance as a therapeutic target in FL.
