Lung-cancer screening with chest computerized tomography (CT) is not easy to introduce in low-medium resource countries due to cost issues. We investigated whether the increasing availability of chest CT exams in Brazil, in spite of no lung-cancer screening protocol, was associated with lung-cancer death rate along 10-year follow-up. We performed regressions to estimate the rate ratio between chest CT exams and lung-cancer deaths per 105 inhabitants. We stratified data per municipality. Regressions were adjusted for physicians and hospital beds per 105 inhabitants and per capita gross domestic product. Increasing availability of chest CT exams predicted decreasing lung-cancer death rate.

肺癌死亡率和胸部X线断层扫描的可用性:一项全国性纵向研究

由于成本问题,在中低资源国家不易采用胸部计算机断层扫描(CT)进行肺癌筛查。我们调查了巴西,尽管没有进行肺癌筛查,但胸部CT检查的可用性增加是否与10年随访期间的肺癌死亡率相关。我们进行了回归分析,以估算每10 5位居民的胸部CT检查与肺癌死亡之间的比率。我们对每个城市的数据进行了分层。对每10 5名居民的医生和医院床位以及人均国内生产总值的回归进行了调整。越来越多的胸部CT检查预示着肺癌死亡率的降低。
