2016 CTFPHC建议：肺癌筛查

This guideline is intended to provide primary care providers and policy-makers with guidance on screening for lung cancer, and replaces the previous 2003 Canadian Task Force on Preventive Health Care recommendations. Since the previous recommendations were published, results from additional studies have been released, including one large randomized controlled trial (RCT) comparing lowdose computed tomography (CT), which uses less ionizing radiation than usual CT scans, with chest radiography. Ongoing trials of screening with lowdose CT are expected to provide more evidence on the effectiveness of screening for lung cancer with low-dose CT. The current recommendations may be updated once these results are available or at least within five years.
