Area of Science:

  • Radiology
  • Oncology
  • Artificial Intelligence

Background:

  • Non-small cell lung cancer (NSCLC) is a leading global cancer.
  • CT imaging is crucial for initial NSCLC diagnosis.
  • Histological evaluation, the gold standard, has lengthy processing times.

Purpose of the Study:

  • Develop AI models for NSCLC overall staging prediction.
  • Utilize patient demographics and CT-derived radiomics.
  • Prioritize later-stage patients for timely histology evaluation.

Main Methods:

  • Two NSCLC patient cohorts used: TCIA and a local hospital.
  • Extracted 107 radiomic features and demographic data.
  • Developed models using artificial neural networks (ANNs) and traditional classifiers.

Main Results:

  • Feed-forward neural network (FFNN) achieved high accuracy: 88.84% (validation), 76.67% (internal), 74.52% (external).
  • Balanced sensitivity and specificity across all stages.
  • Demonstrated good average precision and F1 scores.

Conclusions:

  • FFNN shows strong performance in NSCLC overall staging prediction.
  • The model efficiently predicts multiple stages in one go.
  • Simple, general-purpose computer operation facilitates radiology department integration for faster diagnosis and patient triage.
