采用小剂量计算机断层扫描对肺癌幸存者和其他高危人群进行筛查的指南

Objective: Lung cancer is the leading cause of cancer death in North America. Low-dose computed tomography screening can reduce lung cancer–specific mortality by 20%.

Method: The American Association for Thoracic Surgery created a multispecialty task force to create screening guidelines for groups at high risk of developing lung cancer and survivors of previous lung cancer.

Results: The American Association for Thoracic Surgery guidelines call for annual lung cancer screening with low-dose computed tomography screening for North Americans from age 55 to 79 years with a 30 pack-year history of smoking. Long-term lung cancer survivors should have annual low-dose computed tomography to detect second primary lung cancer until the age of 79 years. Annual low-dose computed tomography lung cancer screening should be offered starting at age 50 years with a 20 pack-year history if there is an additional cumulative risk of developing lung cancer of 5%or greater over the following 5 years. Lung cancer screening requires participation by a subspecialty-qualified team. The American Association for Thoracic Surgery will continue engagement with other specialty societies to refine future screening guidelines.

Conclusions: The American Association for Thoracic Surgery provides specific guidelines for lung cancer screening in North America. (J Thorac Cardiovasc Surg 2012;144:33-8)
