  • Introduction
  • Recruitment and Enrollment
  • Screening for Lung Cancer 
  • Diagnostic Evaluation of Lung Cancer
  • Lung Cancer Data
  • Non-lung Cancer Data
  • Participant Withdrawal
  • Mortality
  • Results
  • Images
  • Biospecimens

Accessing NLST Trial Data and Images

Data and images are owned by the National Cancer Institute (NCI) and subject to IRBs at NCI and at the institutions through which participants were recruited. NLST summary, design, protocols, and results are well-described and publicly available; see: 

https://biometry.nci.nih.gov/cdas/nlst/

ANYONE can access the data and images (with an approved CDAS request);  see:

https://biometry.nci.nih.gov/cdas/studies/nlst

> Non-image Data

Investigators with approved access to NLST data may acquire copies of data in two different ways:

  • Directly from IMS
    Investigators with an approved request may download comprehensive NLST datasets directly from the CDAS website.  Datasets are provided in SAS format in one compressed file (.zip); other formats are available upon request.
  • Indirectly, through the Query Tool (QT): NLST Database Query Tool
    Investigators launch the web-based QT, make menu-driven queries against the QT database (a significant subset of all trial data), and save query results to an Excel spreadsheet.  The chief advantage to the QT is the ability to rapidly adjust queries and build a final spreadsheet for analysis.  In addition, the QT offers the ability to download associated CT image

> Images

CT images:  All CT images are available to investigators with approved access to NLST data and images.  The chest X-rays are not available.  Subsets of the CT images may be obtained in two ways:

  • Request from IMS. Petition IMS for images associated with an NCI-approved project.  IMS notifies The Cancer Imaging Archive (TCIA) management with a list of images to provide.  TCIA pulls the images to an external hard drive (provided by the investigator) and ships the images to the investigator.
  • Request with Query Tool. The investigator uses the Query Tool to define cohorts of subjects using non-image trial data, then directly downloads the associated CT images directly to their computer using the TCIA Download Manager tool.

       For general details about the CT images, see NLST Images -- General Details

Pathology images:  A small number  (~1,250) of lung-biopsy pathology images are viewable using caMicroscope which is launched by the Query Tool.
