Prostate Cancer
Conditions
Brief summary
This is a single center, blinded (the mpMRI will be read by expert personnel not aware of the patient's diagnosis ), retrospective study. A total of 200 patients with suspicious prostate cancer (PCa) who underwent, between January 2014 and January 2022, mpMRI of the prostate and subsequent prostate biopsy will identified. All mpMRI images will be retrospectively collected and evaluated using the Quantib Prostate software. In particular, 200 mpMRI with endorectal coil will be read by the expert radiologist and by the Quantib prostate (Quantib B.V. Rotterdam, The Netherlands) software, thus evaluating the predictive characteristics of Quantib Prostate for the identification of suspicious lesions. The sensitivity, specificity, negative predictive value, positive predictive value and accuracy of Quantib Prostate vs. radiologist in detecting csPCa will be evaluated using the biopsy report as reference standard.
Detailed description
An increasing number of certified software using AI in radiology is becoming available. Nonetheless, the role of AI in the detection of prostate lesions at mpMRI in men with suspicious PCa is still under debate. Specifically, it is unknown whether the use of AI may help clinicians in the decision-making process with a reliable inter-observer agreement compared to assessments done by high-volume experienced dedicated uro-radiologists. In this context, the use of digital platforms available on the market such as Quantib Prostate (Quantib B.V. Rotterdam, The Netherlands) could help in the identification of patients at higher risk of clinically significant PCa (csPCa). Among the other platforms, Quantib Prostate has a validated algorithm for the evaluation of prostate MRI which has been already tested in the clinical setting and which holds a CE mark and authorization for clinical use. Moreover, the use of Quantib Prostate may lead to advantages in terms of time reduction, time-efficiency and diagnostic performance compared with the traditional radiologist approach, with a potential impact on report quality.For these reasons, among the various AI softwares which are currently available, we decided to select Quantib Prostate for these analyses. The potential implication of this study includes: 1. Establishing inter-observer agreement between AI and traditional radiologist approach 2. Time reduction in the diagnosis of suspicious PCa 3. Error reduction within the imaging workflow
Interventions
DEVICEQuantib prostate (Quantib B.V. Rotterdam, The Netherlands) software
Quantib Prostate is an AI-driven solution that provides an intuitive workflow for assessment of prostate MRI. The product integrates essential prostate MRI reading features into one workflow making it easy for the user to read, assess and report each patient case from within the same software interface. With automatic forwarding in place, the software preprocesses the MRI right after scanning. This allows the user to access calculations and analysis immediately when they open the software interface. Thanks to these features, the professional may experience an accelerated workflow, making it easier to manage their heavier workload.
