P1.03-034 Implementing Smartphone Application in Early Lung Cancer Detection and Screening

Abstract

The early detection of NSCLC cases is still the key point of the surgical treatment of lung cancer. Finding the symptomless patients require the system of risk assessment, risk group selection and a controlled screening. The modern communication path of the mobile devices are enabling us a complete new communication and selection method wich can effectively simplify the risk group identification and the suggestion of screening by the Screening Centers. The aim of our study was to determine the effectivity of a lung cancer risk assessment mobile application (LungScreen) in a localised setting. A freely downloadable lung cancer risk assessment application (LungScreen) were created for Android and iOS mobile platforms. The application calculates and shows individual NSCLC risk based on Bach's protocol after collecting demographic data, smoking status, and possible environmental harms of the participant. Based on GPS coordinates the high risk participant is navigated to the nearest Screening Center for further investigation. We analyzed the records of the application in a test period of one year aided by an informative campaign in Hungary. In one year test period more than 70000 participants downloaded and completed the risk assessment test (Male/Female 58%/42%, Age range 9-92 years, mean age 38,2 year). 14238 participants were active smokers, high risk criteria was calculated in 1831 cases, in which further screening investigation were suggested. In our region (Baranya County) 158 LDCT screening were performed, with 32 positive findings which required further investigations. In 9 cases Tumor Board decided to indicate surgery (7 cases NSCLC, 2 cases benign lesion). All the procedures were performed with VATS. 8028 tests from 28 other countries (e.g. Germany, France, UK, USA, Japan etc). Lung cancer risk assessment via mobile devices allows free, fast and efficient way to select, manage and localize high risk population for NSCLC. By omitting the complex recruitment process it can effectively fasten the screening trials and subsequently lower the financial needs. Giving immediate personalized feedback and individual direction to diagnostic centers can facilitate early diagnosis of operable NSCLC cases.
