肺腺鳞癌临床病理学分析

A Clinicopathological Study of Adenosquamous Carcinoma of the Lung

目的探讨肺腺鳞癌临床病理学特点及形态学发生。方法回顾性分析华中科技大学同济医院 2 0 0 1-2 0 0 2年经外科手术切除病理学确诊为肺腺鳞癌 6例 ,分别观察肿瘤的发生率、部位、大小、分期、组织学特征及淋巴结转移等各项病理学指标。结果肺腺鳞癌发生率占原发性肺癌的 3.0 % ,淋巴结转移率 2 0 % ;瘤组织平均直径 4 .3cm ;大多数肺腺鳞癌两种成分之间可相互移行 ;老年男性多见。结论肺腺鳞癌是肺癌中的一种特殊的组织学类型 ,研究腺鳞癌的形态学发生有助于研究肿瘤的发生机制。

Objective To analyse the clinicopathological feature of adenosquamous carcinoma of the lung and discuss its morphogenesis.Methods The frequency rate, locus, size, staging, histological features and lymph node metastasis of 6 adenosquamous carcinoma of the lung, which were resected and final diagnosised at affiliated Tongji hospital from 2001 to 2002,were evaluated retrospectively. Results The frequency rate of adenosquamous carcinoma was 3.0% primary lung cancers, the metastasis rate of lymph node was 20%; the average diameter of tumor was 4.3cm;in most cases the two components of carcinoma can transit each other; and this type of cancer mostly occurred in old male. Conclusion Adenosquamous carcinoma is the special type of lung cancer, and the study of its morphogenesis is helpful to the study of occurrence mechanism of neoplasm.
