Area of Science:

  • Oncology
  • Medical Imaging
  • Artificial Intelligence

Background:

  • Cervical cancer radiotherapy can cause radiation proctitis, a complication with diagnostic challenges.
  • Accurate diagnosis of radiation proctitis is vital for optimizing cervical cancer treatment and patient outcomes.
  • Deep learning excels in image segmentation, while radiomics extracts diagnostic features, but both have limitations.

Purpose of the Study:

  • To develop a novel method combining deep learning and radiomics for improved diagnosis of radiation proctitis in cervical cancer patients.
  • To leverage Transformer-based SAM-Med2D for feature extraction from CT images.
  • To identify key imaging features correlated with radiation proctitis and build predictive models.

Main Methods:

  • Utilized the Transformer-based SAM-Med2D model for segmenting CT images of cervical cancer patients.
  • Applied T-tests and Lasso regression to identify significant radiomic features associated with radiation proctitis.
  • Developed predictive models using logistic regression, random forest, and naive Gaussian Bayesian algorithms.

Main Results:

  • The proposed method successfully extracted relevant CT imaging features.
  • The approach demonstrated excellent performance in diagnosing radiation proctitis.
  • Identified key features correlated with radiation proctitis, enhancing diagnostic capabilities.

Conclusions:

  • The combined deep learning and radiomics approach offers a powerful tool for diagnosing radiation proctitis.
  • This method improves predictive accuracy, aiding in personalized treatment strategies for cervical cancer radiotherapy.
  • The study highlights the potential for advanced AI techniques to enhance patient care and outcomes in gynecological oncology.
