Recommendations for high-risk groups of lung cancer, screening and prevention

High-risk objects
        Age> 40 years old, with at least one of the following risk factors:
        1. Smoking ≥ 20-year pack (annual pack refers to how many packs you smoke per day multiplied by how many years last, for example, 20-year pack refers to 1 pack per day for 20 years or 2 packs per day for 10 years), including smoking cessation less than 15 years;
        2. Passive smoking;
        3. A history of occupational exposure (persons exposed to asbestos, beryllium, uranium, radon, etc.);
        4. Have a history of malignant tumors or a family history of lung cancer;
        5. A history of chronic obstructive pulmonary disease or diffuse pulmonary fibrosis.
 
Screening recommendations
        1. For people at high risk of lung cancer, low-dose spiral CT screening is recommended. It is recommended to use 64-slice or more multi-slice spiral CT for lung cancer screening as much as possible. The scan range is from the tip of the lung to the tip of the costophrenic angle. After the baseline CT scan, according to the specific conditions of the lesion (shape, size, boundary and other characteristics), it is recommended to consult a specialist hospital for the specific next diagnosis and treatment plan;
         2. If a pulmonary nodule is detected, perform LDCT review according to the different characteristics of the nodules, ground glass, subsolid, solid nodules and multiple nodules;
        3. According to the national conditions and effectiveness and the characteristics of the Chinese population, PET/CT is not recommended as a screening method for lung cancer population.
 
Prevention advice
        1. It is recommended to quit smoking;
        2. People at risk of occupational exposure should take protective measures;
        3. Pay attention to avoid indoor air pollution, such as passive smoking, open flames for heating, exposure to oil fume, etc.;
        4. When the atmosphere is severely polluted, avoid going out and exercising;
        5. People with respiratory diseases should be treated in a timely and standardized manner.
