Background: The most common cancer worldwide is bronchiogenic carcinoma, with a 5-year survival rate of <15%. Low-Dose Computed Tomography (LDCT) is a promising tool for early detection of lung cancer in asymptomatic smokers and former smokers. Aim of this study: to assess the detective value of low dose CT scan.

Methods: an analytic retrospective cross-sectional study of low-dose CT scan screening of asymptomatic people (ages 50-74) who are smokers with at least 15 pack years or who quit smoking within 10 years in medical city - oncology teaching hospital from July 31, 2018 to June 17, 2019, totalling 197 people.

Results: This opportunistic lung cancer (CA) screening program included 197 participants (174 from the ministry of oil and 23 from the ministry of transport) who underwent LDCT scans. Results were categorised by lung Reporting and Data System (RADS) and lung RADS 1 had the highest rate (87.7%). 8 of them had lung disease rather than CA and were referred to a pulmonologist, 14 had lung RADS II (7.1%), 7 had lung RADS III (3.6%), and 3 had lung RADS IV (1.5%), one with lung IVa and two with lung IVb (1%) were sent to a cardiothoracic surgeon and biopsied and diagnosed with lung CA.

Conclusion: There is a detective value of low dose CT scan for detection of lung cancer in early stage to be treated as curative intent.
