MRI-Based Machine Learning for Prostate Cancer
What You Need to Know Before You Apply
What is the purpose of this trial?
This trial evaluates the effectiveness of an AI system in detecting prostate cancer using MRI images, compared to traditional radiologist methods. The AI may match experienced radiologists in identifying aggressive prostate cancer. The trial includes several rounds of MRI scans and prostate biopsies to compare results. It targets individuals who have undergone or will undergo a specific type of MRI and are scheduled for a prostate biopsy or prostate removal due to cancer. As an unphased trial, this study allows participants to contribute to cutting-edge research that could enhance prostate cancer detection.
Do I need to stop my current medications for the trial?
The trial information does not specify whether you need to stop taking your current medications. It's best to discuss this with the trial coordinators or your doctor.
What prior data suggests that this MRI-based machine learning approach is safe for detecting prostate cancer?
Research has shown that using AI in MRI scans holds promise for detecting prostate cancer. Studies indicate that AI can help doctors identify aggressive prostate cancers more accurately, allowing for earlier detection when treatment is more manageable. The AI system used in these studies excels at identifying prostate cancer and can also rule out cancer in low-risk cases, helping to avoid unnecessary treatments.
Although this AI system is neither a drug nor a device that interacts with the body, it plays a crucial role in diagnosing cancer. The focus is on its effectiveness in identifying cancer, rather than any direct safety concerns for participants. Overall, using AI in prostate cancer MRI scans is considered safe, as it poses no direct risks to patients.12345Why are researchers excited about this trial?
Researchers are excited about the MRI-Based Machine Learning approach for prostate cancer because it offers a cutting-edge alternative to the traditional methods like the standard biopsy and imaging techniques. This new method leverages artificial intelligence (AI) to enhance the accuracy of prostate cancer detection. By integrating machine learning models with MRI and ultrasound, it provides a more precise mapping of cancerous tissues, potentially reducing the number of unnecessary biopsies. This approach aims to improve diagnosis by using AI predictions, which could lead to earlier and more accurate identification of aggressive cancers, ultimately improving patient outcomes.
What evidence suggests that this trial's MRI-based machine learning approach could be effective for detecting prostate cancer?
This trial will evaluate the effectiveness of an MRI-based machine learning approach for detecting prostate cancer. Studies have shown that using MRI scans with machine learning can effectively detect prostate cancer. One AI system outperformed over 70% of human experts in diagnosing prostate cancer from these scans, demonstrating greater accuracy than most individuals. Another study found that deep learning, a type of AI that learns patterns, accurately identified cancer cases, though it occasionally missed some true cases. Overall, these findings suggest that AI can be a valuable tool in diagnosing prostate cancer, potentially matching or even surpassing human performance in some areas. Participants in this trial will undergo various sequences of MRI/TRUS and targeted prostate biopsies using different AI predictions and methods, as part of the different study arms.26789

Treatment groups
Experimental Treatment
Patients undergo MRI/TRUS then a radical prostatectomy (RP), which are performed per standard of care at our institution. PIRADS, GL AI, and DL AI will be used to interpret the MRI/TRUS results prior to RP.
Patients undergo MRI/TRUS followed by a targeted prostate biopsy using DL AI predictions. Patients then undergo a 2nd MRI/TRUS followed by a targeted prostate biopsy based on GL AI predictions. Patients then undergo a 3rd MRI/TRUS followed by a targeted biopsy using PIRADS. Patients undergo up to 12 additional prostate biopsies per SOC. Based on biopsy results, patients will either come off study or undergo radical prostatectomy without hormonal therapy within 180 days from baseline MRI.
