本文对证实曾有石棉粉尘接触史和不能回忆接触史的恶性胸膜间皮瘤的临床、病理和生存期的差异进行了探索。一组115例胸膜间皮瘤复查肺切除或尸解肺标本的组织切片后,分成上皮型、肉瘤型和混合型3种。115例中83例患者有清楚的石棉粉尘接触史,23例不能回忆石棉粉尘的接触,9例的石棉接触史不详。尸解78例中,每例从肺标本3个不同部位取作无染色30μ切片检查。 This article explored the differences in the clinical, pathological, and life-span of malignant pleural mesothelioma that have demonstrated asbestos dust exposure history and cannot recall contact history. A group of 115 cases of pleural mesothelioma after lung resection or autopsy lung tissue specimens were divided into epithelial, sarcoma and mixed 3 kinds. Of the 115 patients, 83 patients had a clear history of contact with asbestos dust, 23 patients could not recall contact with asbestos dust, and 9 cases of asbestos exposure history were unknown. Of the 78 cases of autopsy, each was taken from 3 different sites of lung specimens for a non-stained 30μ biopsy.
