Trop2-targeting NIR-II Molecular Probe for Precision Diagnosis of Oral Cancer

Summary

Given the morphological and clinical similarities between certain oral malignant neoplasms and benign conditions such as oral ulcerations or inflammatory lesions, the potential for misdiagnosis is significant. Currently, histopathological examination via tissue biopsy remains the diagnostic gold standard; however, this approach is inherently invasive and may yield incomplete diagnostic results due to sampling limitations and spatial heterogeneity of the lesion. These challenges underscore the urgent need for the development of simple, non-invasive, cost-effective, and real-time in vivo imaging modalities. To address this, the investigators propose the utilization of a previously developed near-infrared II (NIR-II) fluorescent molecular imaging probe, TTP-ICG, which exhibits high specificity for TROP2, a transmembrane glycoprotein frequently overexpressed in oral squamous cell carcinoma (OSCC). This study will evaluate the diagnostic accuracy of OSCC through localized application of the TROP2-targeted probe via clinical specimens being soaked in TTP-ICG solution. Furthermore, the investigators aim to explore the feasibility of employing a mouth wash-based delivery system for the probe, with the ultimate goal of establishing a precise, minimally invasive, and cost-effective real-time imaging strategy for the early detection and diagnosis of OSCC. Such an approach has the potential to significantly enhance diagnostic precision, improve patient outcomes, and increase survival rates.
