Low-dose Computed Tomography Screening for Lung Cancer in Relatives With Family History of Lung Cancer

Screening with the use of low-dose computed tomography (LDCT) reduces mortality from lung cancer. Relatives with family history of lung cancer are at increased risk of lung cancer compared to those without a family history in pooled analysis. A prospective trial using LDCT of lung to screen the relatives with family history of lung cancer is needed.

Sex

All

Minimum age

55 Years

Maximum age

75 Years

Inclusion Criteria:

1. relatives of the lung cancer patients;
2. age older than 55 years old or age older than the age of onset of lung cancer proband if the family members were less than 55 years old;
3. compulsory signing the consent agreement after understanding the purpose of study and the exposure of radiation.

Exclusion Criteria:

1. proved lung cancer either with or without treatment,
2. presence of hemoptysis or history of remarkable lung fibrosis,
3. any other cancer history or
4. chest CT examination within one year
