Area of Science:

  • Biomedical Engineering
  • Artificial Intelligence in Oncology
  • Medical Imaging Analysis

Background:

  • Cancer is a leading cause of death, with advanced stages lacking effective treatments.
  • Early cancer diagnosis is critical for reducing mortality rates.
  • Circulating tumor cells (CTCs) show promise for early detection but are difficult to automatically identify due to heterogeneity and scarcity.

Purpose of the Study:

  • To develop an automated method for detecting circulating tumor cells (CTCs) for early cancer diagnosis.
  • To address the challenges of CTC detection, including size/shape heterogeneity and low abundance.
  • To improve the robustness and generalizability of CTC detection models.

Main Methods:

  • Utilized the Segment Anything Model (SAM) and a copy-paste strategy for synthetic data generation.
  • Developed a Swin Transformer-based detection network with specialized adapter modules for scale and shape.
  • Implemented an improved loss function incorporating a regularization term for data distribution consistency.

Main Results:

  • Achieved high performance metrics: accuracy (0.9960), recall (0.9961), precision (0.9804), specificity (0.9975), and mAP (0.9400 at IoU 0.5).
  • Demonstrated robustness and generalizability on a mixed dataset of public and local data.
  • Outperformed state-of-the-art models including ADCTC, DiffusionDet, CO-DETR, and DDQ.

Conclusions:

  • The proposed framework offers a significant advancement in automated CTC detection.
  • This technology can serve as a vital tool for early cancer diagnosis, treatment planning, and prognostic assessment.
  • The approach has the potential to enhance patient outcomes and overall human well-being.
