Area of Science:

  • Oncology
  • Computer Science
  • Medical Imaging

Background:

  • Prostate cancer is a leading cause of cancer deaths in men, necessitating early and accurate diagnosis.
  • Manual histopathological analysis is the gold standard but is labor-intensive and requires expertise.
  • Current diagnostic methods face challenges in speed and consistency.

Purpose of the Study:

  • To develop and evaluate a hybrid deep learning framework for enhanced prostate cancer detection.
  • To integrate local and global feature extraction for improved diagnostic accuracy.
  • To create an efficient AI model suitable for clinical deployment.

Main Methods:

  • A hybrid framework combining ensemble Convolutional Neural Networks (CNNs) and a Vision Transformer (ViT).
  • Utilized transfer learning with VGG-16, DenseNet-121, and AlexNet, alongside a fine-tuned ViT.
  • Incorporated a Cross-Attention Fusion (CAF) module and Knowledge Distillation (KD) for feature integration and efficiency.
  • Trained and tested on the PANDA dataset with preprocessing techniques like gamma correction and stain deconvolution.

Main Results:

  • The proposed hybrid model achieved 97.91% accuracy, outperforming existing methods.
  • Demonstrated significant improvements in True Positive Rate (TPR) and True Negative Rate (TNR), with reduced False Negative Rate (FNR) and False Positive Rate (FPR).
  • Ablation studies confirmed the effectiveness of individual components, especially ensemble CNNs, CAF, and ViT.

Conclusions:

  • The hybrid deep learning model offers a powerful and accurate approach to prostate cancer diagnosis.
  • The AI framework shows potential for expediting diagnosis and enabling timely patient intervention.
  • The model balances predictive accuracy with computational efficiency for clinical applicability.
