肺癌肉瘤的临床分析

目的提高肺癌肉瘤的诊治水平。方法通过２例经手术及病理证实的肺癌肉瘤的病例分析，结合文献复习，对肺癌肉瘤的组织发生，病理，临床特征，诊断，治疗以及与原发性肺癌的鉴别诊断进行了讨论。结果肺癌肉瘤是一种罕见的即含有癌又含有肉瘤两种成分的复合性肿瘤。临床上分为浸润型（周围型）和支气管管内型（中心型）两种。前者肿块位于边缘，生长迅速，早期发生转移；后者肿块位于肺门部，生长缓慢，转移晚。结论肺癌肉瘤常易误诊，预后差。首选治疗为手术切除。

Carcinosarcoma of the lung clinical analysis

OBJECTIVE: To improve the diagnosis and treatment of pulmonary carcinosarcoma. METHOD: Two patients with pulmonary carcinosarcoma were confirmed by operation and pathology were presented and relevant literatures were reviewed. The histo-pathological, clinical features, diagnosis, differential diagnosis and treatment were introduced appearance. RESULT: Carcinosarcoma of the lung is rare. It is 0.2%-0.6% of pulmonary malignant tumor. Carcinosarcoma of the lung may be divided into 2 types: First, the endbronchial type which tends to grow slowly in a polypoid pattern along the major bronchi with local invasive feature. The second, arising peripherally which tends to metastasize early with serious outcome. CONCLUSION: This tumor may be misdiagnosed as brondrogeuic carciniose preoperatively. It tends to metastasize early and prognosis is poor. Surgical intervention is the first choice.
