F-082SMARTPHONE APPLICATION FOR FAST LUNG CANCER RISK ASSESSMENT

Abstract

Objectives: The importance of early non-small-cell lung cancer (NSCLC) diagnosis is inevitable but 75% of the cases are still diagnosed in an advanced, inoperable stage. Screening the high risk population with ldCT can improve the early diagnosis, but it might be aggravated by the complex task of risk group selection and recruitment. The aim of our study was to create and test a novel way to select and manage high risk population for NSCLC with smart communication devices. Mobile phones, tablets offering fast data analysis and record via software applications adding the possibility of geographical localization with GPS coordinates. Method(s): We constructed a free lung cancer risk assessment application (LungScreen) 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, possible environmental harms of the participant. Based on GPS coordinates the high risk participant is navigated to the nearest screening centre for further investigation. We analyzed the records of the application in a 2-month test period aided by an informative campaign in Hungary. Result(s): In the 2-month test period 6141 participants downloaded and completed the risk assessment test (male/female 3888/2253, age range 8-89 years, mean age 36.01 years). There were 3081 participants who were active smokers, high risk criteria was calculated in 519 cases, in whom further screening investigation were suggested. A total of 5113 results were from Hungary and 1028 tests were from 28 other countries (e.g. Germany, France, UK, USA, Japan, etc) Conclusion(s): Lung cancer risk assessment via mobile devices allows a free, fast and efficient way to select, manage and localize high risk population for NSCLC. By omitting the complex recruitment process it can aid to initiate screening trials. Giving immediate personalized feedback and individual direction to diagnostic centres can facilitate early diagnosis of operable NSCLC cases.
