Using a tiny high-resolution camera and mouth-cell testing to find oral precancer

Evaluation of Two Non-Invasive Methods, High-Resolution Microendoscopy and Liquid-Based Cytology, for Detection of Oral Precancer

Not applicable Interventional National Institutes of Health Clinical Center (CC) · NCT07260344

This project tests whether a high-resolution microendoscope or liquid-based cytology can better find precancer and guide biopsy decisions in people aged 30–80 with visible oral lesions.

What this trial studies

This is a randomized, cross-sectional study comparing two non-invasive approaches—high-resolution microendoscopy (HRME) and liquid-based oral cytology—against standard clinical impression for triage of visible oral lesions. Patients with visible oral precancerous lesions are randomized to have biopsies guided by either the clinician's examination or HRME, while cytology and clinical impressions are collected for comparison across participants. The main outcomes are histopathologic diagnoses of any dysplasia and high-grade disease (moderate dysplasia or worse). The study is conducted at National Taiwan University Hospital and combines data across arms to compare performance for biopsy triage and lesion detection.

Who should consider this trial

Good fit: Ideal candidates are people aged 30–80 with a visible oral precancerous lesion at least 1 cm in diameter who can give informed consent.

Not a fit: People currently receiving cancer treatment, those who had cancer within the past 12 months, or individuals without visible oral lesions are unlikely to benefit from participating.

Why it matters

Potential benefit: If successful, these methods could help detect precancer earlier and reduce unnecessary biopsies.

How similar studies have performed: Similar HRME and cytology techniques have shown promising results for detecting mucosal dysplasia in prior research but have not yet replaced standard biopsy-based diagnosis.
