Evaluation of AI Medical Software-assisted LDCT Interpretation in Lung Cancer Screening and Prognosis: a Randomized Controlled Trial

Overview

This multicenter pragmatic randomized controlled trial evaluates whether AI-assisted interpretation of low-dose CT (LDCT) improves lung cancer screening performance compared with standard reading. Eligible participants are randomized to AI-assisted or conventional interpretation. The study assesses diagnostic accuracy, efficiency, lung cancer incidence, mortality, recurrence, and smoking cessation outcomes. Results will inform the clinical utility and potential implementation of AI-assisted LDCT in routine screening practice.

Detailed description

Lung cancer is a leading cause of cancer-related mortality worldwide, and early detection is essential for improving survival. Low-dose computed tomography (LDCT) has been shown to reduce lung cancer mortality in high-risk populations, but image interpretation is time-consuming and may lead to overdiagnosis. Artificial intelligence (AI)-assisted diagnostic tools offer the potential to improve accuracy and efficiency in LDCT-based lung cancer screening, though challenges related to model adaptability, data heterogeneity, user trust, and regulatory compliance remain.

This multicenter pragmatic randomized controlled trial evaluates the effectiveness of AI-assisted LDCT interpretation compared with standard interpretation. Eligible participants will be randomized to an AI-assisted arm or a standard-reading arm. Outcomes include diagnostic accuracy, efficiency, lung cancer incidence, lung cancer mortality, recurrence, and smoking cessation.

The findings will provide evidence on the clinical utility of AI-assisted LDCT screening and support future implementation in routine practice and policy development.

Interventions

  • Diagnostic test AI-assisted Low-Dose CT Interpretation
    Participants undergo low-dose computed tomography (LDCT) lung cancer screening. The images are first interpreted by AI-assisted software, which highlights suspicious nodules. Radiologists then review the AI outputs and generate the final report.

Primary outcome measures

  • Lung Cancer Incidence [Time frame: From baseline to 12 months, 36 months, and 60 months.]
  • False Positive Rate [Time frame: Within 6 months following LDCT screening.]
Secondary outcome measures (7)
  • Lung Cancer Mortality [Time frame: From baseline to 12 months, 36 months, and 60 months.]
  • Lung Cancer Recurrence Rate [Time frame: From baseline to 12 months, 36 months, and 60 months.]
  • All-Cause Mortality [Time frame: From baseline to 12 months, 36 months, and 60 months.]
  • Time to Diagnosis [Time frame: At the 12-month, 36-month, and 60-month follow-up assessments after LDCT screening.]
  • Time to Treatment Initiation [Time frame: At the 12-month, 36-month, and 60-month follow-up assessments after lung cancer diagnosis.]
  • Follow-up Completion Rate [Time frame: Up to 12 months post-screening.]
  • Smoking Cessation Rate [Time frame: Assessed at 3 months, 6 months, and 12 months after baseline screening.]

Eligibility criteria

Inclusion criteria

  • Family History of Lung Cancer: Males aged 45-74 or females aged 40-74 with first-degree relatives (parents, siblings, or children) diagnosed with lung cancer.
  • Heavy Smoking History: Ages 50-74 with ≥20 pack-years smoking history, currently smoking or quit <15 years ago.
  • General Screening Participants: Adults aged 40 years or older attending routine health check-ups.

Exclusion criteria

  • Pregnant women.
  • Chest CT or other higher-radiation chest imaging within the past 12 months.
  • Individuals holding a major illness certificate for lung cancer.
  • Inability to undergo thoracic puncture or surgery.
  • Inability to hold breath or otherwise complete the scanning procedure.
  • Hemoptysis of unknown cause within the past month.
  • Chest X-ray within the past month showing suspicious lung lesions.
  • Unexplained weight loss >6 kg within the past year.
  • History of lung cancer within the past three years.
  • Presence of other severe diseases with an expected life expectancy <5 years.
