摘要 目的:探讨多发性骨髓瘤(multiple myeloma,MM)患者血清游离轻链(serum free light chain,sFLC)检测的临床意义。方法:初诊MM患者43例采用免疫透射比浊法检测血清sFLC水平,以健康体检者20例为对照组。32例MM患者采用硼替佐米为主方案进行化疗,检测化疗前后血清sFLC水平。结果:对照组血清κFLC、λFLC水平及κ/λFLC分别为7.43±0.91 mg/L,14.43±1.22 mg/L和0.48±0.26,均在标准参考区间内。43例MM患者中18例为κ轻链,25例为λ轻链,其血清κFLC、λFLC分别为114.62±0.62 mg/L和153.41±1.52 mg/L,均高于标准参考区间,且高于对照组,差异均有统计学意义(P<0.05)。κ-MM组及λ-MM组患者κ/λFLC比值分别为8.54±1.51和0.21±0.13,均位于标准参考区间外。32例MM患者化疗后CR 14例,化疗后血清κ链为11.52±5.43 mg/L,λ链为9.71±4.34 mg/L,分别低于化疗前的104.62±7.63 mg/L和148.49±7.56 mg/L;PR 9例,化疗后血清κ链为18.37±4.76 mg/L,λ链为16.76±5.18 mg/L,分别低于化疗前的109.76±6.56 mg/L和147.52±6.53 mg/L,有效患者化疗前后血清sFLC水平比较,差异均有统计学意义(P<0.05)。无效患者化疗前后血清sFLC水平比较,差异均无统计学意义(P>0.05)。结论:sFLC检测用于MM诊断及判断治疗效果具有较高的临床意义。
