The early detection of NSCLC cases is still the key point of the surgical treatment of lung cancer, but 75% of the cases are still diagnosed in an advanced, inoperable stage. Screening with ldCT of the high risk population can improve the early diagnosis, but it might be aggravated by the complex task of risk group selection and recruitment. 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.
Key words: lung cancer, screening, VATS lobectomy
We constructed a free lung cancer risk assessment application (LungScreen) for selecting high risk population in Baranya County, Hungary 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 Center for further investigation. We analysed the records of the application in a two month test period aided by an informative campaign in Hungary.
In one year test period 12780 participants downloaded and completed the risk assessment test (Male/Female 58%/42%, Age range 9-92 years,mean age 38,2 year). 2750 participants were active smokers, high risk criteria was calculated in 789 cases, in which further screening investigation were suggested. 158 LDCT screening were performed, with 32 positive findings wich 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.
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 aid to initiate screening trials. Giving immediate personalised feedback and individual direction to diagnostic centers can facilitate early diagnosis of operable NSCLC cases.
