报告１７例矽肺合并肺癌，其中煤矿工７例，铁矿工５例，耐火材料工３例，其他工种２例。癌发部位多在肺上叶。组织学类型：鳞状上皮细胞癌７例，未分化细胞癌６例，腺癌４例；轻度尘肺合并的肺癌，从组织形态上看不出二者有何内在联系，但在重度尘肺中，癌原发部位与矽肺块一致。癌组织与矽肺病变交织融合，形成＂矽肺－肿瘤块＂。减寿比分析表明，合并肺癌者减寿高峰在４５岁和５０岁年龄组，认为尘肺合并肺癌的现象值得进一步研究。 Seventeen cases of silicosis and lung cancer were reported, including 7 miners, 5 miners, 3 refractory workers and 2 other workers. Cancer sites and more in the lungs. Histological types: squamous cell carcinoma in 7 cases, undifferentiated carcinoma in 6 cases, adenocarcinoma in 4 cases; mild pneumoconiosis complicated with lung cancer, from the organizational morphology do not see the two are intrinsically linked, but in severe pneumoconiosis , The same site of primary cancer and silicosis. Cancer tissue and intertwined silicosis lesions, the formation of “silicosis - tumor mass.” Life-loss ratio analysis showed that the peak of life expectancy in patients with lung cancer was in the age group of 45 and 50 years old, and the phenomenon of pneumoconiosis complicated with lung cancer deserved further study.
