Overview
According to the U.S. Preventive Services Task Force (USPSTF), screening for lung cancer by low-dose computed tomography (LDCT) is recommended every year among smokers who are between 55 to 80 years old and who have history of smoke 30 pack-years or more and either continue to smoke or have quit within the past 15 years (grade B recommendation).
Screening
Guidelines
- According to the clinical practice guideline by the U.S. Preventive Services Task Force (USPSTF), screening for lung cancer by low-dose computed tomography (LDCT) is recommended every year among smokers and former smokers who are between 55 to 80 years old and who have smoked 30 pack-years or more and either continue to smoke or have quit within the past 15 years (grade B recommendation).[1][2]</nowiki>[3][4]
- According to the American College of Chest Physicians (CHEST) in 2013, screening for lung cancer by low-dose CT (LDCT) is recommended every year among smokers and former smokers who are aged between 55 and 74 years and who have smoked for 30 pack-years or more and either continue to smoke or have quit within the past 15 years.[5]

Strategies
- Low-dose helical computed tomography:[6]
- Benefits
- There is evidence that screening persons aged 55 to 74 years who have cigarette smoking histories of 30 or more pack-years and who, if they are former smokers, have quit within the last 15 years reduces lung cancer mortality by 20% and all-cause mortality by 6.7%.
- Harms
- The majority of of all positive low-dose helical computed tomography screening exams do not result in a lung cancer diagnosis.
- False-positive exams may result in unnecessary invasive diagnostic procedures.
- Benefits
- Screening with chest x-ray and/or sputum cytology does not reduce mortality from lung cancer in the general population or in ever-smokers.
- Harms
- False positive exams
- The majority of all positive chest x-ray screening exams do not result in a true positive diagnosis of lung cancer.
- False-positive exams result in unnecessary invasive diagnostic procedures.
Over-diagnosis
- Based on current evidence, the majority of non-small cell lung cancers detected by screening chest x-ray and/or sputum cytology appear to represent over-diagnosed cancer.[8]
- The magnitude of over-diagnosis appears to be between 5% and 25%.
- These cancers result in unnecessary diagnostic procedures and also lead to unnecessary treatment.
- Harms of diagnostic procedures and treatment occur most frequently among long-term and/or heavy smokers because of smoking-associated co-morbidities that increase risk propagation.
