65例云锡井下矿工肺癌标本的病理学观察表明:矿工肺癌的组织学类型以鳞癌为主,95%的病例具有尘肺样病理改变,其病变特点为肺内有大量矿尘沉积并伴有弥漫性肺间质纤维化,支气管上皮细胞增生、鳞状上皮细胞化生和肺泡立方样上皮细胞呈腺样增生。作者认为肺癌发生与尘肺病变有密切关系。
The pathological observations of 65 lung cancer samples from miners in Yunxi province showed that the histological type of miners’ lung cancer was squamous cell carcinoma, with 95% of cases having pneumoconiosis-like pathological changes characterized by a large amount of deposits of mineral deposits in the lung with Diffuse pulmonary fibrosis, bronchial epithelial cell proliferation, squamous metaplasia and alveolar epithelial cells were adenoid hyperplasia. The authors believe that the occurrence of lung cancer and pneumoconiosis are closely related.
