Prognostic Significance of Blood Transfusion in Elderly Patients with Primary Diffuse Large B-Cell Lymphoma

Abstract EN

The current study sought to evaluate whether blood transfusions affect survival of elderly patients with primary diffuse large B-cell lymphoma (DLBCL).

A total of 104 patients aged 60 years and over were enrolled and divided into two groups: 24 patients who received transfusions and 80 patients who did not.

Statistical analyses showed significant differences in LDH levels, platelet (Plt) counts, and hemoglobin (Hb) and albumin (Alb) levels between the two groups.

Univariate analyses showed that LDH level ≥ 245 IU/L, cell of origin (germinal center/nongerminal center), and blood transfusion were associated with both overall survival (OS) and progression-free survival (PFS).

Higher IPI (3–5), Alb level < 35 g/L, and rituximab usage were associated with OS.

Appearance of B symptoms was associated with PFS.

Multivariate analyses showed that cell of origin and rituximab usage were independent factors for OS and LDH level was an independent factor for PFS.

Blood transfusion was an independent factor for PFS, but not for OS.

Our preliminary results suggested that elderly patients with primary DLBCL may benefit from a restrictive blood transfusion strategy.
