Key requirements

Who can take part, as listed by the sponsor. Only the study team can confirm whether you are eligible, so take this list to your doctor.

  • Ages 30 to 80 years
  • All sexes
  • Healthy volunteers accepted
  • Adult, Older adult

Study population: We proposed to include individuals aged 30-80 years with prevalent oral precancer with or without a prior history of head and neck cancer (oral cavity, oropharynx, hypopharynx, larynx).

Inclusion Criteria:We proposed to include individuals aged 30-80 years with prevalent oral precancer with or without a prior history of head and neck cancer (oral cavity, oropharynx, hypopharynx, larynx). The rationale for including those with history of cancer is that they are still at risk of developing oral cavity cancer and therefore will benefit from a better screening algorithm. Also, in our experience lesions in cancer survivors are phenotypically similar to those without a prior history of head and neck cancer. Only lesions with at least 1 cm in greatest diameter will be considered eligible. Additionally, because there could be issues in HRME imaging due to keratinization at some anatomic sites, we will divide lesions into approximate quadrants and exclude any lesions that do not have good nuclear resolution on at least one representative image per quadrant.

-

Exclusion Criteria:We exclude those who: 1) are undergoing current cancer treatment or had a cancer within the last two years to avoid any effects of the cancer treatments; 2) are unwilling or unable to provide informed consent to participate; and/or 3) based on clinical judgement, should not be included in the study e.g., has other medical conditions that would preclude them from participating.

About this study

Oral cancer is a common cancer worldwide, with approximately 250,000 new cases annually and a high mortality rate. Its major risk factors include smoking, alcohol consumption, and betel nut chewing. Current screening methods rely heavily on visual inspection by specialist physicians and invasive biopsy of lesions, but they suffer from limitations such as insufficient sensitivity, sampling errors in biopsies, and low patient compliance.

This study proposes an innovative cross-sectional randomized trial aimed at evaluating two non-invasive techniques-oral digital imaging photography (high-resolution microendoscopy, HRME) and liquid-based cytology (LBC) of the oral mucosa-in order to optimize the screening of oral precancerous lesions.

Read the detailed description

Oral cancer is a common malignancy worldwide, with approximately 250,000 new cases diagnosed annually and a high mortality rate. Its primary risk factors are smoking, alcohol consumption, and betel nut chewing. Current screening methods heavily rely on visual inspection by specialist physicians and invasive biopsy of lesions, but they are limited by insufficient sensitivity, biopsy sampling errors, and low patient compliance.

To address these issues, this study proposes an innovative cross-sectional randomized trial to evaluate two non-invasive techniques-high-resolution microendoscopy (HRME) and liquid-based cytology (LBC) of the oral mucosa-with the aim of optimizing screening for oral precancerous lesions.

The study will recruit 400 participants with visually identified oral potentially malignant disorders (e.g., leukoplakia or erythroplakia) and randomly assign them to two groups:

a clinical biopsy group (biopsy site selected based on conventional visual inspection), and an HRME-guided biopsy group (biopsy site directed by high-resolution microendoscopy).

Both groups will also undergo liquid-based cytology (LBC) through collection and analysis of oral mucosal cells.

The study objectives include:

Comparing the detection rates of precancerous lesions (mild, moderate, severe dysplasia, or carcinoma in situ, or invasive cancer) between the two groups; Analyzing the intra-lesional consistency of biopsy sites in both groups; Validating the diagnostic performance of LBC alone or in combination with HRME.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Whether the biopsy sites are consistent

    Whether the biopsy site selected based on conventional physician visual inspection is the same area as the biopsy site selected with the assistance of oral digital imaging (high-resolution microendoscopy, HRME) each time.

    Measured: one month

Individual data sharing
Yes: For the needs of this research, the specimens we collect from you will be used in accordance with this research protocol. The specimens will be stored either in the laboratory of Dr. Cheng-Ping Wang at National Taiwan University Hospital or at the U.S. National Institutes of Health (NIH) and will be retained for a maximum of 30 years. Upon expiration of the 30-year storage period, the specimens will be destroyed in accordance with the law. To protect your personal privacy, your name and other personally identifiable information will be replaced with a unique study/research ID number, ensuring that your specimens and related data remain completely confidential.

Questions about this trial

What is this clinical trial studying?

An observational study of Oral Cancer Screening, run by National Taiwan University Hospital at 1 site in Taiwan.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: under way, not looking for participants, as of the sponsor's last update on 25 Nov 2025. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in Taiwan. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

This study is still under way. Results are not available in the source record yet.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Whether the biopsy sites are consistent (time frame: one month). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 25 Nov 2025.
