对鞍钢职工中 2 93例胃癌新发病例及 95 9例对照进行调查。经对食用酸菜、既往胃病史、家族胃癌史、食用水果等非职业因素调整后 ,岗位工龄等于或超过 15年者的下列工人的胃癌危险度显著增高 :铁矿石烧结工和皮带运输工 (OR =2 1,95 %CI =1 2～ 5 6 ) ;耐火砖厂工 (OR =2 5 ,95 %CI =1 1～ 5 8) ;装卸工 (OR =3 2 ,95 %CI =1 2～ 8 9) ;锅炉工和厨师(OR =2 6 ,95 %CI =1 2～ 5 6 ) ;焦炉工 (OR =5 4,95 %CI =1 8～ 16 0 )。各种粉尘和苯并芘 (B〔a〕p)暴露与胃癌呈显著的剂量 -反应关系 ,但与粉尘的特殊成分未见此种关联。长期暴露于污染物的钢铁工人胃癌危险度均增加 40 %。
A total of 2 93 newly diagnosed cases of gastric cancer in Anshan Iron and Steel Company workers and 959 controls were investigated. After adjusting for non-occupational factors like eating pickled cabbage, previous stomach history, familial gastric cancer history, eating fruits and other non-occupational factors, the risk of gastric cancer was significantly increased for the following workers who worked for more than 15 years: Iron Ore Sinters and Belt Transporters OR = 2 1,95% CI = 1 2 ~ 5 6); refractory brick factory workers (OR = 25.95% CI = 11-58) 2 ~ 8 9); boilers and cooks (OR = 26.95, 95% CI = 12-656); coke oven workers (OR = 5.45% CI = 18-18). Various dusts and benzopyrene (B [a] p) exposure showed a significant dose-response relationship with gastric cancer, but not with the special dust composition. Long-term exposure to pollutants in steel workers increased the risk of gastric cancer by 40%.
