Background: Poor prognosis of lung cancer is linked to its late diagnosis, typically in the advanced stage 4 in 50-70% of incidental cases. Lung Cancer Screening Programs provide low-dose lung CT screening to current and former smokers who are at high risk for developing this disease. Greece is an EU country, returning strong from a long period of economic recession, ranked 2nd place in overall age-standardized tobacco smoking prevalence in the EU. In December 2020, at the Metropolitan Hospital of Athens, we started the 1st Screening Program in the country. We present our initial results and pitfalls met. Method(s): A weekly outpatient clinic offers consultation to possible candidates. LDCT (<=3.0mGy), Siemens VIA, Artificial Intelligence multi-computer-aided diagnosis (multi-CAD) system and LungRADS (v.1.1) are used for the validation of any abnormal findings with semi-auto measurement of volume and volume doubling time. Patients get connected when necessary with the smoking cessation and Pulmonology clinic. USPSTF guidelines are used, (plus updated version). Abnormal CT findings are discussed by an MDT board with radiologists, pulmonologists/interventional pulmonologists, oncologists and thoracic surgeons. A collaboration with Fairlife Lung Cancer Care the first non-profit organization in Greece is done, in order to offer the program to population with low income too. An advertisement campaign was organized to inform family doctors and the people about screening programs, together with an anti-tobacco campaign. Result(s): 106 people were screened, 74 males & 32 females (mean age 62yo), 27/106 had an abnormal finding (25%). 2 were diagnosed with a resectable lung cancer tumor (primary adenocarcinoma) of early-stage (1.8%). 2 with extended SCLC (lung lesion & mediastinal adenopathy). 1 with multiple nodules (pancreatic cancer not known until then). 3 patients with mediastinal and hilar lymphadenopathy (2 diagnosed with lymphoma, 1 with sarcoidosis). 19 patients were diagnosed with pulmonary nodules (RADS 2-3, 17%) - CT follow up algorithm. Conclusion(s): We are presenting our initial results, from the first lung cancer screening program in Greece. Greece represents a country many smokers, who also started smoking at a young age, with a both public and private health sector, returning from a long period of economic recession. COVID-19 pandemia has cause practical difficulties along the way. LDCT with AI software, with an MDT board and availability of modern diagnostic and therapeutic alternatives should be considered as essential. A collaboration spirit with other hospitals around the country is being built, in order to share current experience and expertise. Copyright © 2022
