The serum free light chain (FLC) assay quantitates free immunoglobulin kappa and lambda light chains, which has prognostic value in plasma cell dyscrasias. However, there is limited data on serum FLC in lymphoid malignancies. We analyzed the association of pretreatment FLC with event-free survival (EFS) and overall survival (OS) in 100 patients with Hodgkin lymphoma (HL). Elevated polyclonal FLC were present in 30% of patients; these patients had an inferior EFS (HR = 4.84; 95% CI: 1.84-12.7) and OS (HR = 8.87; 95% CI: 2.35-33.52) compared to patients with normal FLC. Further studies of FLC in HL are warranted.
血清游离轻链(FLC)检测定量游离免疫球蛋白 κ 和 λ 轻链,其在浆细胞疾病中有预后价值。然而,关于淋巴恶性肿瘤的血清 FLC 数据有限。我们分析了 100 例霍奇金淋巴瘤(HL)患者的预处理 FLC 与无事件生存(EFS)和总生存(OS)的关系。30%的患者存在多克隆 FLC 升高;与 FLC 正常的患者相比,这些患者的 EFS(HR=4.84;95%CI:1.84-12.7)和 OS(HR=8.87;95%CI:2.35-33.52)更差。进一步研究 FLC 在 HL 中的作用是必要的。
