Trial summary

Nasopharyngeal carcinoma (NPC) occurs at a high frequency in southern China, northern Africa, and Alaska, with a reported incidence of 30 cases per 100 000 in Guangdong Province. Endoscopic examination and biopsy are the main methods used for detection and diagnosis of NPC. Read more about this study

About this study

Nasopharyngeal carcinoma (NPC) occurs at a high frequency in southern China, northern Africa, and Alaska, with a reported incidence of 30 cases per 100 000 in Guangdong Province. Endoscopic examination and biopsy are the main methods used for detection and diagnosis of NPC. Early NPC patients achieve favourable prognoses after concurrent radiotherapy and chemotherapy in compassion with advanced NPC patients.

Here, the investigators focused on the utility of artificial intelligence to detect early NPC, which based on white light imaging (WLI) and Narrow-band imaging (NBI) nasoendoscopic examination. Having access to this unique population provides an unprecedented opportunity to investigate the effect of intelligent system on diverse nasopharyngeal lesions detection and develop a novel Computer-Aided Diagnosis System.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • rigid nasal endoscopesDiagnostic test

    The endoscope is introduced through the nasal passage to observe, in sequence, the posterior nostril, superior and posterior walls of the nasopharynx, torus tubarius, pharyngeal opening of the auditory tube, and Rosenmu¨ller recess. The imaging light mode is set to conventional WLI and subsequently switch to NBI during the procedure, and representative images are collected and preserve for further analysis. All lesions, detected by either WLI or NBI, are biopsied.

Study groups in NCT04547673
Study groupRoleWhat they receive
NPC groupPatients pathologically diagnosed as NPC by agreement of 2 experienced pathologists who were blinded to the corresponding endoscopic assessment.
Receives: Diagnostic Test: rigid nasal endoscopes
Non-NPC groupPatients pathologically diagnosed as non-NPC (including inflammatory hyperplasia, Atypical hyperplasia, Papilloma etc.) by agreement of 2 experienced pathologists who were blinded to the corresponding endoscopic assessment.
Receives: Diagnostic Test: rigid nasal endoscopes

What is being measured

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

  1. Pathological diagnosis

    All lesions, detected by either WLI or NBI, are biopsied. 2 experienced pathologists, who were blinded to the endoscopic and intelligent assessment, evaluate the pathological nature of the biopsied lesion independently, and 2 professors with over 10 years of experience in Otolaryngology and pathology department are consulted in cases of disagreement.

    Measured: baseline

Secondary outcomes (1)
  1. Lesion range

    All images in which lesions are pathologically diagnosed as NPC are collected. 2 experienced pathologists, who were blinded to the endoscopic and intelligent assessment, delineated the malignant area in the images independently, and 2 professors with over 10 years of experience in Otolaryngology department are consulted in cases of disagreement.

    Measured: baseline

Questions about this trial

What is this clinical trial studying?

An observational study of Otolaryngological Disease and Artificial Intelligence, run by First Affiliated Hospital, Sun Yat-Sen University at 3 sites in China.

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

Who may be eligible to take part?

The sponsor lists 1 inclusion and 2 exclusion criteria. 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: looking for participants now, as of the sponsor's last update on 20 Feb 2024. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 3 sites in China. 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?

Contact Yihui Wen, Ph.D (+86-13480200660, wenyihui@mail.sysu.edu.cn), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Pathological diagnosis (time frame: baseline). It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT04547673, which also lists 1 linked publication.

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 20 Feb 2024.
