摘要
目的比较乙酰胆碱受体抗体(ACh R-Ab)阳性全身型重症肌无力(MG)与ACh R-Ab阴性全身型MG患者胸腺切除术的疗效。方法将124例于胸外科接受胸腔镜胸腺扩大切除术的全身型MG患者,根据术前血清ACh R-Ab表现,分为ACh R-Ab阳性组(81例)和ACh R-Ab阴性组(43例),比较两组患者的完全稳定缓解率。结果两组患者的性别、手术时年龄、术前病程、首发症状及胸腺病理类型等基本情况组间比较差异无显著性。术后ACh R-Ab阳性组失访1例,阴性组失访2例,共完成随访121例患者,随访时间15~84个月,其中ACh R-Ab阳性组80例,随访(44.9±19.9)个月,ACh R-Ab阴性组41例,随访(48.2±20.3)个月。术后完全稳定缓解率ACh R-Ab阳性组(48.8%)显著高于ACh R-Ab阴性组(26.8%),χ2=5.372,P=0.020。术后总有效率ACh R-Ab阳性组为95.0%,ACh R-Ab阴性组为90.2%,两组比较差异无统计学意义(χ2=0.993,P=0.319)。完全稳定缓解率的Kaplan-Meier生存曲线提示,随着术后随访时间的延长,完全稳定缓解率逐渐升高;Log-rank法比较两组之间的完全稳定缓解率均逐渐升高(P=0.03)。结论血清ACh R-Ab阳性患者胸腺扩大切除术后完全稳定缓解率优于ACh R-Ab阴性患者,随着随访时间的延长,完全稳定缓解率逐渐升高,但两组患者的总有效率类似。
