CAR/CSTR Practice Guideline on CT Screening for Lung Cancer.

Area of Science:

• Oncology
• Radiology
• Public Health

Background:

• Lung cancer is a leading cause of cancer death in Canada.
• Previous guidelines require updates based on new research and trial data.
• Implementing organized screening programs is crucial for early detection.

Purpose of the Study:

• To provide updated practice guidelines for CT screening for lung cancer in Canada.
• To support diagnostic imaging departments in establishing organized lung cancer screening programs.
• To reduce lung cancer mortality through early detection in high-risk individuals.

Main Methods:

• Utilizes low-dose CT (LDCT) for screening eligible individuals based on risk prediction models (e.g., PLCOm2012).
• Incorporates findings from the NELSON trial and provincial screening program data.
• Details requirements for radiologist training, standardized protocols, quality assurance, and AI integration for nodule risk stratification.

Main Results:

• Updated evidence supports LDCT screening for reducing lung cancer mortality.
• Established criteria for selecting high-risk individuals for screening.
• Outlined essential components for successful program implementation and quality assurance.

Conclusions:

• The updated guideline provides a framework for implementing effective lung cancer screening programs in Canada.
• Emphasizes the role of LDCT, risk-based eligibility, and technological advancements like AI.
• Highlights future research directions, including biennial screening and equitable access.
