Retrospective Clinical Trial Comparing Radiologists' Diagnosis Accuracy in Lung Cancer Screening Population With and Without the Help of an AI/ML Tech-based SaMD
RELIVE
A Multi-Reader Multi-Case Controlled Clinical Trial to Evaluate the Comparative Accuracy Of Readers Assisted By an AI/ML Technology-Based End-To-End CADe/CADx SaMD Versus Alone in the Detection, Localization and Characterization of Pulmonary Nodules in Populations With High Risk of Lung Cancer (RELIVE)

Brief Summary
This is a two arm, randomized, controlled, blinded, multi-case multi reader (MRMC), retrospective study for the evaluation of the efficacy and safety of an AI/ML technology-based CADe/x developed to detect, localize and characterize malignancy score of pulmonary nodules on LDCT chest scans taken as part of a lung cancer screening program. LDCT DICOM images of patients who underwent routine lung cancer screening will be selected and enrolled into the study. Enrolled scans analyzed by radiologists with the assistance of the Median LCS (formerly iBiopsy) device are compared to the analysis by radiologists without the assistance of the Median LCS device. Figures of merit for patient level and lesion level detection and diagnostic efficacy will be calculated and compared, sub-class analysis will be performed to ensure device generalizability.

Study Arms (2)
Control arm
low-dose CT scan image readings performed by radiologists without the assistance of Median LCS
Test arm
low-dose CT scan image readings performed by radiologists with the assistance of Median LCS.
Interventions
End-to-end processing of chest LDCT DICOM images by an AI/ML tech-based SaMD to detect, localize, and characterize (assign a malignancy score) each detected pulmonary nodule. The output of the device is a DICOM File (Median LCS result report) summarizing results per patient.
Eligibility Criteria
High risk lung cancer population from Radiology or Pneumology hospital departments. Patients enrolled in this study were retrospectively collected from centers across the EU and USA where they were enlisted into lung cancer screening due to high risk of lung cancer according to established lung cancer screening guidelines. The cohort used for testing the efficacy and safety of the device will be an "enriched cohort" with a 1:2 distribution of cancer positive and benign patients
You may qualify if:
- ≥50-80 Years of age;
- Current or ex-smoker (\>=20 pack years);
- Patient screened and surveilled for lung cancer screening following lung cancer screening guidelines (equivalent to United States Preventive Services Task Force (USPSTF) 2021 Criteria);
You may not qualify if:
- Prior lung resection;
- Pacemaker or other indwelling metallic medical devices in the thorax that interfere with CT acquisition;
- Patients/images used during AI model development;
- Patients with only hilar and/or mediastinal cancer(s);
- Patients with only ground glass cancer(s);
- Patients with nodules, solid or part-solid \>30mm (masses);
- Patients that are not accompanied with the required clinical information;
- Patients with imaging with any of the following: missing slices, slice thickness \>3mm;
- Partial cover of the lung.
