Prognostic value of serum albumin level in patients with diffuse large B cell lymphoma.

Abstract

To investigate the prognostic value of serum albumin (SA) levels before chemotherapy in patients with diffuse large B-cell lymphoma (DLBCL) after receiving chemotherapy. This is a retrospective study, and 127 patients with DLBCL including 71 males (55.9%) and 56 females (44.1%) were included. Patients' gender, age, Ann Arbor staging, eastern cooperative oncology group (ECOG) score, treatment options, international prognostic index, response rate, overall survival (OS), and progression-free survival (PFS) were obtained for statistical analysis. Univariate analysis showed that SA≤34 g/L, Ann Arbor III-IV, B symptoms, ECOG≥2, and bone marrow involvement suggest a poor prognosis in patients with DLBCL. Patients with persistent SA>34 g/L had significantly longer OS than patients with persistent SA≤34 g/L (P=0.020). Multivariate analysis showed that SA≤34 g/L (HR=0.48, 95% CI=0.26-0.90, P=0.022) and R-CHOP-like treatment regimen (HR=0.43, 95% CI=0.24-0.76, P=0.004) are independent factors that could affect the prognosis of patients with DLBCL. SA can be used as an indicator of prognosis in patients with DLBCL before the first chemotherapy. DLBCL patients with SA≤34 g/L are associated with short OS and poor prognosis, which may potentially provide guidance for the clinician to pay more attention to this population before the first chemotherapy.
