📚 Background
Prostate cancer remains a significant health concern, with a notable percentage of patients experiencing biochemical recurrence (BCR) after treatment. Traditional methods for predicting BCR often overlook critical histopathological features, leading to a gap in effective preoperative planning. The integration of advanced technologies like deep learning offers a promising avenue to enhance predictive accuracy and patient outcomes.
🗒️ Study
The study involved the collection of 1,585 prostate biopsy images from 317 patients, with each patient contributing five whole slide images. Researchers employed the Inception_v3 neural network to train models based on patch-level images, utilizing a multiple instance learning approach to extract features at the whole slide image level. This innovative methodology aimed to improve the prediction of BCR prior to prostatectomy.
📈 Results
The developed prediction system demonstrated remarkable performance, achieving an AUC of 0.911 in the testing cohort. The results indicated a 95% Confidence Interval ranging from 0.840 to 0.982, showcasing the model’s reliability. Furthermore, the study emphasized the importance of increasing the number of WSIs per patient to enhance predictive capabilities.
🌍 Impact and Implications
The implications of this study are profound, as it paves the way for more personalized and targeted treatment strategies for prostate cancer patients. By leveraging deep learning to predict BCR, healthcare providers can make informed decisions that may lead to improved patient outcomes and optimized surgical approaches. This research highlights the transformative potential of artificial intelligence in oncology and pathology.
🔮 Conclusion
This study illustrates the significant advancements in predicting biochemical recurrence in prostate cancer through the use of a deep learning system.

Development of a deep learning system for predicting biochemical recurrence in prostate cancer.
Abstract
BACKGROUND: Biochemical recurrence (BCR) occurs in 20%-40% of men with prostate cancer (PCa) who undergo radical prostatectomy. Predicting which patients will experience BCR in advance helps in formulating more targeted prostatectomy procedures. However, current preoperative recurrence prediction mainly relies on the use of the Gleason grading system, which omits within-grade morphological patterns and subtle histopathological features, leaving a significant amount of prognostic potential unexplored.
METHODS: We collected and selected a total of 1585 prostate biopsy images with tumor regions from 317 patients (5 Whole Slide Images per patient) to develop a deep learning system for predicting BCR of PCa before prostatectomy. The Inception_v3 neural network was employed to train and test models developed from patch-level images. The multiple instance learning method was used to extract whole slide image-level features. Finally, patient-level artificial intelligence models were developed by integrating deep learning -generated pathology features with several machine learning algorithms.
RESULTS: The BCR prediction system demonstrated great performance in the testing cohort (AUC = 0.911, 95% Confidence Interval: 0.840-0.982) and showed the potential to produce favorable clinical benefits according to Decision Curve Analyses. Increasing the number of WSIs for each patient improves the performance of the prediction system. Additionally, the study explores the correlation between deep learning -generated features and pathological findings, emphasizing the interpretative potential of artificial intelligence models in pathology.
CONCLUSIONS: Deep learning system can use biopsy samples to predict the risk of BCR in PCa, thereby formulating targeted treatment strategies.
