摘　　要：目的 :探讨中心型非小细胞肺癌不同的病理组织学类型与 pTNM分期对癌细胞浸润近端支气管壁长度的影响 ,为术式的选择提供临床病理依据。方法 :86例原发性中心型非小细胞肺癌的手术标本 ,用细探针探测支气管腔 ,沿探针剖开支气管壁全层至肿瘤处 ,测量肿瘤边缘至支气管切缘的最近距离 ,对肿瘤至支气管切缘的管壁进行连续取材 ,常规病理制片、显微镜下观察组织学类型 ,测量癌细胞浸润近端支气管的长度。结果 :Ⅲa期腺癌最长 ,为 (1.91±0.36)cm ,Ⅰb期鳞癌最短为 (0.39±0.15)cm ,且差别有统计学意义。结论 :在原发性中心型非小细胞肺癌中 ,病理组织学类型、pTNM分期与癌细胞浸润近端支气管壁的长度有关 ,可作为选择术式的依据之一。Objective:To investigate the effects of different types and pTNM stages on proximal bronchial extension in hilar type non_small cell lung cancer(NSCLC)and provide a clinicopathological basis for a curative resection.Methods:Eighty_six surgical specimens of primary hilar type NSCLC were collected.Macroscopic and microscopic proximal bronchial invasion lengths were measured from bronchial resection margins to tumor edges.Results:The invasive lengths of adenocarcinomas of stageⅢa were the longest(1.91±0.36)cm.The invasive lengths of squamous cell carcinomas of stageⅠb were the shortest(0.39±0.15)cm,which were sigˉnificantly different(P<0.05).Conclusion:The extension of invasion is correlated with the histopathologic type of cancer and TNM classification,which is one of the clinicopathological bases for a curative resection.
