近年来流行病研究结果指出煤矿工人中肺癌死亡率较低而胃癌死亡率增高。美国和英国也有报道煤矿工人中胃癌过高危险性。胃癌的真正病因学尚未阐明。但Ames1982年提出职业性接触,生活方式和人群的易感性可能为煤矿工人中胃癌增高的危险因素。Falk和Jurgelshi 1979年提出煤矿尘可能是患胃癌的危险因素。1976年Jacobsen的研究发现胃癌死亡率和尘肺的进展之间有相一致的趋向,因尘肺的进展为持续接触煤尘的函数,因而作者作出胃癌死亡率的增加可能与接触煤尘有联系的推断。大多
In recent years, epidemiological studies have shown that coal miners have lower rates of lung cancer mortality and higher gastric cancer mortality rates. There are also reports in the United States and the United Kingdom of the high risk of gastric cancer in coal miners. The true etiology of gastric cancer has not been elucidated. However, Ames’s erroneous attitude toward lifestyles and population susceptibility, introduced in 1982, may be a risk factor for increased gastric cancer in coal miners. Falk and Jurgelshi proposed in 1979 coal mine dust may be a risk factor for gastric cancer. A 1976 study by Jacobsen found a consistent trend between gastric cancer mortality and progression of pneumoconiosis as the progression of pneumoconiosis was a function of continued exposure to coal dust and therefore the authors suggested that an increase in gastric cancer mortality could be inferred from the association with exposure to dust . most
