JAMA Surg:为获得小肠神经内分泌瘤准确分期至少需切除8个淋巴结

2018-11-06 zhangfan MedSci原创

研究认为,小肠神经内分泌肿瘤根治性切除的患者,为获得准确的淋巴结分期至少需要8个淋巴结,存在4个以上淋巴结阳性人群的3年预后变差,彻底的区域淋巴结切除是准确分期和治疗疾病的关键

小肠神经内分泌瘤患者接受肠系膜淋巴结切除术时,为获得准确患者分期需要多少淋巴结信息?近日研究人员考察了淋巴结阳性和淋巴结数对小肠神经内分泌肿瘤准确分期及预后的影响。

199名小肠神经内分泌肿瘤且接受原发肿瘤根治性手术切除的患者参与研究,主要终点为无复发生存率。

参与者中男性112人,平均年龄60.3岁,平均BMI29.5,淋巴结阳性患者154例(77.4%)。总体而言,淋巴阳性或阴性人群3年无复发生存率差异不显著,但4个淋巴阳性人群的3年无复发生存率相比于1-3个或阴性人群降低(81.6% vs 91.4% vs 92.1%)。淋巴切除数量少于8个患者中,4个以上、1-3个或0个淋巴阳性患者的3年无复发生存率分别为100% vs 93.8% vs 91.7%,但对于切除数量超过8个的患者,4个以上、1-3个或0个淋巴阳性患者的3年无复发生存率分别为79.9% vs 89.6% vs 92.9%。

研究认为,小肠神经内分泌肿瘤根治性切除的患者,为获得准确的淋巴结分期至少需要8个淋巴结,存在4个以上淋巴结阳性人群的3年预后变差,彻底的区域淋巴结切除是准确分期和治疗疾病的关键。
