Enhancing Clinically Significant Prostate Cancer Prediction in T2-weighted Images through Transfer Learning from Breast Cancer
This work addresses the challenge of accurate prostate cancer diagnosis for patients, but it is incremental as it applies an existing transfer learning technique to a new domain.
The paper tackled the problem of predicting clinically significant prostate cancer from T2-weighted MRI images by using transfer learning from breast cancer data to overcome limited datasets, achieving over 30% improvement in leave-one-out cross-validation accuracy.
In 2020, prostate cancer saw a staggering 1.4 million new cases, resulting in over 375,000 deaths. The accurate identification of clinically significant prostate cancer is crucial for delivering effective treatment to patients. Consequently, there has been a surge in research exploring the application of deep neural networks to predict clinical significance based on magnetic resonance images. However, these networks demand extensive datasets to attain optimal performance. Recently, transfer learning emerged as a technique that leverages acquired features from a domain with richer data to enhance the performance of a domain with limited data. In this paper, we investigate the improvement of clinically significant prostate cancer prediction in T2-weighted images through transfer learning from breast cancer. The results demonstrate a remarkable improvement of over 30% in leave-one-out cross-validation accuracy.
