Chest:间质性肺部异常与肺癌风险

2019-08-11 xing.T MedSci原创

由此可见,无症状间质性肺部异常是肺癌的独立危险因素,可纳入风险评分模型中。

一些间质性肺病与肺癌有关。然而,尚不清楚无症状的间质性肺部异常是否会带来独立的风险。近日,呼吸领域权威杂志chest上发表了一篇研究文章,该研究旨在评估间质性肺部异常是否与肺癌风险增加有关。 

研究人员分析了来自全国肺癌试验(NSLT)的所有参与者的数据,排除了已经存在间质性肺病或肺癌的受试者。该研究主要分析包括接受低剂量计算机断层扫描的患者; 那些接受胸部X线检查的患者被纳入确证分析。有网状/网状结节混浊、蜂窝状、纤维化或瘢痕形成迹象的参与者被归类为有间质性肺部异常。研究人员分别使用泊松和Cox回归比较伴有和不伴有间质性肺部异常的参与者肺癌发病率和死亡率。

在初步分析中纳入LDCT的25041名参与者中,20.2%有间质性肺部异常。肺间质异常的参与者肺癌发病率较高(IRR为1.61,95%CI为1.30-1.99)。在调整后的分析中,间质性肺部异常与较高的肺癌发病率相关(IRR为1.33,95%CI为1.07-1.65)。肺间质异常的参与者肺癌特异性死亡率也更高。在对接受胸部X线检查的参与者分析中得到了类似的结果。

由此可见,无症状间质性肺部异常是肺癌的独立危险因素,可纳入风险评分模型中。
