| 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:≤2 cm组,2~3 cm组,>3 cm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。 |

| Abstract: |
| ObjectiveTo study the metastasis frequencies and areas of solitary bronchioloalveolar carcinoma(BAC) of different diameters, so as to guide the intraoperative lymph node dissection. MethodsA 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. ResultsThe 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). ConclusionThe 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. |
