This study introduces an improved YOLO-based algorithm for precise lung cancer detection and classification. The novel approach enhances early diagnosis by accurately identifying non-small cell lung cancer subtypes and stages within a unified framework.

Area of Science:

  • Medical Imaging
  • Artificial Intelligence
  • Oncology

Background:

  • Early lung cancer detection and classification are vital for treatment planning.
  • Current computer-aided diagnosis (CAD) systems often perform binary classification or separate feature classification and staging.
  • Technical challenges include scale variation, subtle inter-class differences, and complex backgrounds.

Purpose of the Study:

  • To propose an end-to-end fine-grained lung cancer object detection algorithm using an improved YOLO architecture.
  • To address limitations in existing CAD systems for complex lung cancer classification tasks.
  • To achieve unified detection and classification of normal tissue, non-small cell lung cancer (NSCLC) subtypes, and TNM stages.

Main Methods:

  • Developed an improved YOLO architecture for a 7-class detection task (normal, 3 NSCLC subtypes, anatomical locations with TNM stages).

    • Achieved 97.6% Precision and 99.2% mean Average Precision (mAP@0.5) on a dataset of 1886 images.
    • Maintained low parameters (2.46 M) and computational cost (6.3 GFLOPs).
    • Demonstrated superior localization precision and fine-grained classification compared to mainstream object detection algorithms.

    Conclusions:

    • The proposed algorithm offers a unified framework for complex, fine-grained lung cancer detection and classification.
    • Architectural enhancements significantly improve performance in medical vision tasks.
    • The method shows potential for advancing early diagnosis and clinical treatment planning in lung cancer.
