Area of Science:

  • Urology
  • Oncology
  • Artificial Intelligence in Medicine

Background:

  • Penile cancer is aggressive, and delayed presentation due to awareness issues and stigma impacts survival.
  • Early recognition of penile cancer is critical for patient outcomes.
  • Differentiating penile cancer from benign or precancerous lesions is clinically important.

Purpose of the Study:

  • To develop and evaluate a convolutional neural network (CNN) model for differentiating penile squamous cell carcinoma (SCC) from precancerous and benign penile lesions.
  • To assess the diagnostic performance of the AI model using image data.

Main Methods:

  • A CNN model was trained on 136 penile lesion images from open-access publications.
  • The dataset comprised 65 penile SCC, 44 precancerous, and 27 benign lesions.
  • Model performance was evaluated using 10-fold cross-validation and key diagnostic metrics.

Main Results:

  • The CNN achieved an AUROC of 0.94 in distinguishing penile SCC from benign lesions (sensitivity 0.82, specificity 0.87).
  • Performance was lower when differentiating precancerous lesions from SCC (AUROC 0.74).
  • The model demonstrated potential but requires further validation.

Conclusions:

  • Artificial intelligence, specifically CNNs, holds potential for identifying penile SCC.
  • The study highlights the need for larger datasets and real-world validation for clinical application.
  • Further research is warranted to refine AI tools for penile lesion diagnosis.
