目的 :探讨肺癌肉瘤的临床病理特点及其组织来源。方法 :对 2例肺癌肉瘤进行临床病理资料回顾性分析、光镜观察 ,并结合文献对其组织发生、临床表现、诊断及治疗方法进行分析。结果 :肺癌肉瘤主要症状为咳嗽、胸痛、血丝痰等 ,X线示病灶边缘清楚 ,有分叶。镜下见癌与肉瘤共存 ,2例均可见胚胎性支气管结构。结论 :肺癌肉瘤临床特征与肺癌不易区别且预后差 ,外科手术是其主要的治疗手段。组织学特征支持单克隆起源学说。
Objective: To investigate the clinicopathological characteristics of lung cancer sarcoma and its tissue source. Methods: The clinical and pathological data of 2 cases of lung cancer were retrospectively analyzed and observed by light microscopy. The occurrence, clinical manifestations, diagnosis and treatment of lung cancer were analyzed. Results: The main symptoms of pulmonary sarcoma cough, chest pain, bloody sputum, X-ray showed a clear edge of the lesion, lobulated. Microscope see cancer and sarcoma coexist, two cases were visible embryonic bronchus structure. Conclusion: The clinical features of lung cancer are not easily distinguished from those of lung cancer and the prognosis is poor. Surgery is the main treatment. Histological features support the theory of monoclonal origin.
