本文报道我所自1956～1984年经外科手术切除,并由病理证实的局限性细支气管肺泡癌32例,占同期原发性支气管肺癌2.4%。细支气管肺泡癌无典型症状,X线图像多变,肿块边界清楚或不清楚,有分叶或毛刺。值得提出的是肺泡癌的胸膜皱缩征占58.5%,痰脱落细胞检查阳性率为34.4%。临床上易误诊为结核、炎症等。本组无淋巴结转移者5年生存率为41.6%,较其它原发性肺癌为佳。 This article reported 32 cases of localized bronchioloalveolar carcinoma that were surgically resected from 1956 to 1984 and confirmed by pathology, accounting for 2.4% of primary bronchial lung cancer in the same period. Bronchioalveolar carcinoma has no typical symptoms, X-ray images are variable, the mass is clearly defined or unclear, and there are lobes or burrs. It is worth mentioning that 58.5% of the pleural fold marks of alveolar carcinoma and 34.4% of the positive rate of sputum exfoliated cells. Clinically misdiagnosed as tuberculosis, inflammation, etc. The 5-year survival rate of this group without lymph node metastasis was 41.6%, which is better than other primary lung cancer.
