我们对手术治疗的12例孤立性细支气管肺泡癌进行临床分析。在诊断方面,X线检查无明显特征性,CT检查可了解纵隔淋巴结转移的情况,经皮肺穿可提高本病的诊断率。病理分型,分泌型1例;非分泌型9例;低分化型2例;经随访,后者预后欠佳。治疗上均应手术切除,对于低分化型细支气管肺泡癌则应最大限度地保留功能肺组织。 We performed a clinical analysis of 12 patients with isolated bronchioloalveolar carcinoma treated with surgery. In terms of diagnosis, X-ray examination has no obvious characteristics. CT examination can understand the situation of mediastinal lymph node metastasis. Percutaneous lung wear can improve the diagnosis rate of this disease. Pathological type, secretory type 1; non-secretory type 9; poorly differentiated type 2; follow-up, the latter poor prognosis. Surgical resection should be performed. For poorly differentiated bronchioloalveolar carcinoma, functional lung tissue should be preserved as much as possible.
