在世界范围内,由于慢性阻塞性肺病和肺癌导致的死亡率一直居高不下。流行病学研究结果显示,慢性阻塞性肺病是肺癌的独立风险因素。虽然两种肺部疾病截然不同,但是二者在发病遗传易感性、细胞损伤、炎症反应等发病机理存在一定内在联系。笔者拟对慢性阻塞性肺疾病同肺癌相互关系研究概况作一综述。 Worldwide, mortality due to chronic obstructive pulmonary disease and lung cancer has remained high. Epidemiological studies have shown that chronic obstructive pulmonary disease is an independent risk factor for lung cancer. Although both lung diseases are distinct, there is a certain relationship between the two pathogenesis such as genetic susceptibility, cell injury and inflammatory reaction. I intend on the relationship between chronic obstructive pulmonary disease and lung cancer research summary to be reviewed.
