近年来，女性肺癌的发病率在世界范围内迅速上升，除与吸烟和大气污染有关外，最近研究表明肺结核是一个独立的病因因素。我们应用多聚酶链反应技术检测女性肺癌中的结核杆菌ＤＮＡ（ＴＢ－ＤＮＡ），并探讨与女性肺癌临床病理的关系。１材料与方法１．１材料 选用南方医院病理 In recent years, the incidence of lung cancer in women has risen rapidly around the world. In addition to smoking and air pollution, recent studies have shown that tuberculosis is an independent etiological factor. We used polymerase chain reaction to detect Mycobacterium tuberculosis DNA (TB-DNA) in female lung cancer and to explore its relationship with the clinicopathological features of female lung cancer. 1 Materials and Methods 1.1 Materials Selection Southern Hospital pathology
