摘要：SummaryDiagnostic protocol for prostate cancer (KP) is affected by poor accuracy and high false-positive rate. The most promising innovative approach is based on urine analysis by electronic noses (ENs), highlighting a specific correlation between urine alteration and KP presence. Although EN could be exploited to develop non-invasive KP diagnostic tools, no study has already introduced EN into clinical practice, most probably because of drift issues that hinder EN scaling up from research objects to large-scale diagnostic devices. This study, proposing an EN for non-invasive KP detection, describes the data processing protocol applied to a urine headspace dataset acquired over 9 months, comprising 81 patients with KP and 41 controls, for compensating the drift. It proved effective in mitigating drift on 1-year-old sensors by restoring accuracy from 55% up to 80%, achieved by new sensors not subjected to drift. The model achieved, on double-blind validation, a balanced accuracy of 76.2% (CI95%51.9–92.3).Graphical abstractDisplay OmittedHighlights•Urine odor alteration due to prostate cancer can be detected by electronic noses•Sensors drift hinders electronic nose scaling up to large-scale diagnostic devices•OSC mitigates drift on 1-year-old sensors, restoring accuracy from 55% up to 80%Diagnostics; Diagnostic technique in health technology; Natural sciences; Chemistry; Chemical engineering; Biological sciences; Biotechnology; Cancer;
