本院1967—1984年底共收治矽肺病人673例,其中合并肺癌10例,占1.49％。10例中,Ⅱ期矽肺合并肺癌4例;Ⅲ期矽肺合并肺癌6例。中央型6例,周围型4例。10例均为男性、隧道工(其中3例从事过石工),年龄40～60岁,平均55.1岁。接尘工龄4～39年(均有4—8年高浓度粉尘接尘史),平均15.9年。该10例为50年代开始从事隧道粉尘作业,粉尘浓度一般为300～600mg/m~3,最高达1,325mg/m~3;游离SiO_2含
At the end of 1967-1984, 673 cases of silicosis patients were treated in our hospital, of which 10 cases were complicated with lung cancer, accounting for 1.49%. In 10 cases, stage Ⅱ silicosis with lung cancer in 4 cases; stage Ⅲ silicosis with lung cancer in 6 cases. Central type in 6 cases, peripheral type in 4 cases. Ten cases were male, tunnel workers (three of them engaged in masonry), aged 40 to 60 years, mean 55.1 years old. Dust-receiving age 4 to 39 years (both 4-8 years of high concentration dust dust history), an average of 15.9 years. The 10 cases started to work as tunnel dust in the 1950s. The dust concentration is generally 300-600 mg / m3, up to 1,325 mg / m3. Free SiO2
