The Diagnostic Accuracy of the Device Under Development MULTISCOPE (MULTISCOPE)
In Vitro Pilot Study to Assess the Diagnostic Accuracy of the Device Under Development MULTISCOPE
Conventional gastrointestinal endoscopy relies on ex vivo histopathology, a process limited by diagnostic delays and high costs. The MULTISCOPE project introduces a miniaturized (2.2 mm) endoscopic device integrating advanced optical biopsy with Cold Argon Plasma (CAP) therapy. Utilizing multimodal optical fibers, the system performs label-free, high-resolution imaging via two-photon autofluorescence and second-harmonic generation.
Simultaneously, the integrated CAP technology enables targeted oncological treatment by inducing apoptosis and cell-cycle arrest with minimal collateral damage. Given that Endoscopic Submucosal Dissection (ESD) inherently provides samples containing both neoplastic and healthy margins (5-8 mm safety zone), this platform allows for precise, real-time tissue characterization. This in vitro pilot study evaluates the system's diagnostic accuracy in discriminating between healthy and neoplastic colorectal tissues.

Intervention / Traitement |
|---|---|
|
Expérimental: Patients who require endoscopy with endoscopic submucosal dissection (ESD) of the colon.
Thirty consecutive colorectal specimens resected via endoscopic submucosal dissection (ESD) will be analyzed.
Each specimen serves as an internal control, comprising both central neoplasia and healthy peripheral margins ("fried-egg" morphology).
To ensure maximum accuracy with this novel device, optical biopsies will be performed on both tissue types immediately prior to formal histopathological fixation.
ESD procedures will be conducted at the Agostino Gemelli Foundation, while optical and histopathological analyses will be centralized at the Catholic University of Rome (UCSC).
|
Protocol and Transport Colorectal ESD specimens will be resected at the Fondazione Gemelli IRCCS and immediately transported dry (without formalin) to the UCSC Pathological Anatomy Unit within 15 minutes. To ensure tissue viability, dedicated staff will coordinate the transfer directly from the endoscopy suite. Ex Vivo Analysis The MULTISCOPE device will be stationed at the UCSC facility, adjacent to the pathology lab. Upon arrival, Prof. Vincenzo Arena's team will perform multimodal fiberoptic optical biopsies on both healthy and neoplastic mucosa before proceeding with standard histopathological processing. |

Description de la mesure |
Délai |
|---|---|---|
|
Diagnostic Accuracy (Area Under the ROC Curve [AUC]) of the MULTISCOPE Device for Differentiating Normal versus Neoplastic Colorectal Tissue
Délai: At the time of histopathological evaluation, approximately 2 weeks after the surgical procedure.
|
The diagnostic accuracy of optical biopsies performed with the two-photon microendoscope MULTISCOPE prototype will be assessed and compared against standard ex vivo histopathology (gold standard) as the reference diagnosis. Diagnostic performance will be evaluated based on the Area Under the Receiver Operating Characteristic Curve (AUC). Optimal sensitivity, specificity, positive predictive value (PPV), and negative predictive value (NPV) with 95% confidence intervals will also be calculated using the Youden Index threshold. AUC values range from 0.5 (no discrimination) to 1.0 (perfect diagnostic accuracy). |
At the time of histopathological evaluation, approximately 2 weeks after the surgical procedure.
