Trial Summary

What is the purpose of this trial?

This clinical trial studies wide-field and high resolution in vivo imaging in visualizing lesions in patients with abnormal or uncontrolled oral cell growth (neoplasia) undergoing surgery. Diagnostic procedures, such as wide-field and high resolution in vivo imaging, are devices that let researchers look at a wide area of the lining of the mouth by shining different colors inside the mouth and taking pictures and this may help doctors to decide if a mouth lesion has a high risk of being pre-cancerous or cancerous.

Will I have to stop taking my current medications?

The trial protocol does not specify whether you need to stop taking your current medications. However, you cannot participate in another clinical trial where you are actively receiving treatment while being part of this study.

What data supports the effectiveness of the treatment High-Resolution Microendoscopy for oral cancer?

High-resolution microendoscopy (HRME) has been shown to effectively distinguish between benign and cancerous tissues in various parts of the body, such as the upper aerodigestive tract and colorectal polyps, by providing real-time, detailed images of cell structures. This suggests it could be useful for identifying cancerous changes in oral tissues as well.12345

Is high-resolution microendoscopy safe for humans?

High-resolution microendoscopy (HRME) has been used safely in studies for various conditions, including head and neck cancer, colorectal polyps, and sinonasal pathology. The use of proflavine, a contrast agent, in these studies has not shown any significant safety concerns, indicating that HRME is generally safe for human use.12367

How does the treatment using Multispectral + High-Resolution Microendoscopy for Oral Cancer differ from other treatments?

This treatment is unique because it uses high-resolution microendoscopy (HRME) to provide real-time, non-invasive imaging of the mucosal surface, helping to distinguish between benign and cancerous tissues during surgery. This approach can improve the accuracy of identifying cancerous tissue and surgical margins compared to traditional methods, which are often more time-consuming and dependent on expert analysis.12348

Findings from Research

High-resolution microendoscopy (HRME) enables real-time, non-invasive imaging of the upper aerodigestive tract, allowing for effective differentiation between benign and malignant tissues based on their nuclear organization and cellular architecture.
The study provides a comprehensive image collection that highlights unique imaging characteristics of various mucosal types, which can aid in accurate intraoperative diagnosis and early cancer detection.

High-resolution optical imaging using proflavine can effectively distinguish between cholesteatoma and normal middle ear epithelium by highlighting the unique characteristics of keratin, which appears as hyperfluorescent areas without nuclei.
This imaging technique may improve surgical outcomes by enabling real-time identification of residual cholesteatoma, potentially leading to more complete removal of the disease during surgery.

In a study involving 38 patients with head and neck squamous cell carcinoma, high-resolution microendoscopic (HRME) imaging demonstrated a mean accuracy of 97% for specialists in identifying cancerous tissue, indicating its potential as a reliable tool for real-time margin assessment during surgery.
The inter-rater reliability among the seven trained specialists was high, with a Fleiss kappa statistic of 0.84, suggesting that HRME can be effectively used by different medical professionals to improve surgical outcomes.
