To examine associations between radiologic nodule characteristics and histologic subtypes in lung cancers detected through screening in the NELSON-POP project.
Approach:
Design and population: Retrospective observational cohort study using data from Dutch NELSON sites. Participants were high-risk current or recent former smokers aged 50–74 years who underwent baseline and follow-up LDCT.
Imaging assessment: Screening-trained thoracic radiologists blinded to histology assessed nodule diameter, volume, attenuation, location, and volume doubling time (VDT). The scan nearest histologic diagnosis was used for lesion features; VDT used longitudinal scans.
Histology and lesion matching: Histologic diagnoses were obtained from national pathology registries and classified using WHO criteria. Two experienced radiologists matched cancers to index nodules using anatomical and morphological criteria, resolving disagreements by consensus.
Key Findings:
The supplied context describes the study objective and methods but does not report its results.
Interpretation:
The study was designed to assess whether CT characteristics are associated with histologic subtype among screen-detected, histologically verified lung cancers.
Limitations:
The provided excerpt ends before the study results and does not include the complete methods or analysis details.
Exact nodule coordinates were unavailable; index lesions were matched retrospectively using anatomical and morphological criteria.
For participants with synchronous malignant lesions, only one index lesion was retained, and histology was not necessarily available for every synchronous lesion.

This twice-monthly newsletter highlights recently published research where Dana-Farber faculty are listed as first or senior authors. The information is pulled from PubMed and this issue notes papers published from May 16 - 31.
Each year, the American Society of Clinical Oncology Annual Meeting brings together cancer specialists from around the world to share the research most likely to shape the next chapter of cancer care. This year’s major updates point to several important themes: more precise treatment, smarter use of surgery and chemotherapy, new approaches for difficult-to-treat cancers and a growing recognition that supportive care, including exercise, can be part of cancer treatment planning.
