[The Expression Level and Diagnostic Value of Serum Free Light Chain in B-Cell Non-Hodgkin Lymphoma].

Objective: To investigate the expression level and the diagnostic value of serum free light chain in B-cell non-Hodgkin's lymphoma (B-NHL).

Methods: We retrospectively analyzed the results of serum free light chain (sFLC) of 394 newly treated B-NHL patients in our hospital from January 2014 to December 2021 and compared the secretion levels of sFLC among different subtypes of B-NHL. The value of sFLC secretion levels in the diagnosis of WM was evaluated using ROC.
