摘要
目的初步探讨不同直径单发细支气管肺泡癌(bronchioloalveolar carcinoma,BAC)的淋巴结转移频度及区域间差别,以指导临床术中淋巴结清扫。方法收集手术治疗、病理诊断为BAC的肺孤立性结节137例,根据肿瘤直径分为3组:≤2cm组,2～3cm组,>3cm组。分析组间N1、N2组淋巴结转移率的差异。结果 3组患者间N1组淋巴结转移率差异有统计学意义(P<0.05),对于直径较大病变,术中应对第10组淋巴结完整清扫;3组患者间N2组淋巴结转移率差异无统计学意义。结论 BAC肿瘤直径可能对术中N1组淋巴结清扫更有指导价值。
Objective To study the metastasis frequencies and areas of solitary bronchioloalveolar carcinoma（BAC） of different diameters,so as to guide the intraoperative lymph node dissection.Methods A total of 137 patients with pathologically-confirmed solitary BAC received surgical treatment.The patients were divided into 3 groups according to tumor diameters： ≤2 cm group,2-3 cm group,and 3 cm group.The N1 and N2 lymph node metastasis rates of the 3 groups were analyzed.Results The N1 lymph node metastasis rates were significantly different between the 3 groups（P〈0.05）;for tumors with greater diameter,the tenth group lymph nodes should be completely dissected.The N2 lymph node metastasis rates were not significantly between the 3 groups（P〈0.05）.Conclusion The tumor diameter of BAC may be used to guide the dissection extent of N1 group lymph nodes,but not that of N2 group lymph nodes.
