The overall prognosis of lung cancer is poor: Only every 8 patient survives 5 years after diagnosis. This outcome is partly attributable to late diagnosis. To implement a screening program for early diagnosis, selection of high-risk individuals is essential. Our aim was to construct a personalized lung cancer risk assessment tool using geographic localization to lead the high-risk individuals to the local health care provider.
A smartphone application was created for Android and iOS mobile platforms using a risk assessment questionnaire. The software provides immediate classification into low, moderate and high-risk groups. The high-risk group is directed to the nearest screening centre based on GPS location. The complete test data set is recorded on a collection server database for further analysis.
The application was downloaded 13 890 times and completed by 89 500 persons over a period of 20 months. The mean age of the tested users was 36.91 years (9-93 years); the majority were men living in an urban area (62.3%). The test was completed by 38 850 active smokers and 26 710 persons who reported having already quit smoking, resulting in 30 072 moderate and 10 740 high-risk users.
This free application is an active communication tool for most smartphone owners. It helps those who might need further medical attention. The affected users can be easily connected and localized via the smartphone, which helps recruit individuals into screening programs.
肺癌的总体预后较差：确诊后只有八分之一的患者能存活5年。这种结果部分归因于诊断较晚。为实施早期诊断的筛查计划，选择高危个体至关重要。我们的目标是构建一种个性化的肺癌风险评估工具，利用地理定位引导高危个体前往当地医疗服务机构。
使用风险评估问卷为安卓和iOS移动平台创建了一款智能手机应用程序。该软件可立即将用户分类为低、中、高风险组。高危组会根据GPS定位被引导至最近的筛查中心。完整的测试数据集记录在收集服务器数据库中以供进一步分析。
该应用程序在20个月内被下载13890次，89500人完成了测试。测试用户的平均年龄为36.91岁（9 - 93岁）；大多数是居住在城市地区的男性（62.3%）。38850名现吸烟者和26710名报告已戒烟的人完成了测试，产生了30072名中度风险用户和10740名高风险用户。
这款免费应用程序是大多数智能手机用户的积极沟通工具。它帮助那些可能需要进一步医疗关注的人。受影响的用户可以通过智能手机轻松联系并定位，这有助于招募个体参加筛查计划。
