About this study

This bidirectional cohort study (retrospective + prospective) focuses on three key challenges in oral mucosal melanoma (OMM): clinical staging based on depth of invasion (DOI), molecular subtyping, and precision therapy. By integrating DOI-driven T-stage reclassification, genomic profiling, and longitudinal follow-up, we aim to build a population-specific, high-quality evidence resource to support refined staging, CDK4-targeted treatment, and prognostic modeling for Chinese OMM patients.

Read the detailed description

Study Design This is a multicenter, bidirectional (retrospective + prospective) observational cohort study designed to establish a high-quality evidence platform for oral mucosal melanoma (OMM), a rare malignancy with high aggressiveness and poor prognosis. The study is conducted at four tertiary hospitals in China: Shanghai Ninth People's Hospital (lead center), Air Force Medical University Stomatological Hospital, Xiangya Hospital of Central South University, and Sun Yat-sen Memorial Hospital of Sun Yat-sen University.

Study Population The cohort will include a total of 1,100 Chinese patients with histopathologically confirmed primary OMM.

Retrospective cohort (n=800): Patients diagnosed between January 2015 and June 2025, with complete medical records, pathological slides, and available follow-up data.

Prospective cohort (n=300): Consecutive newly diagnosed patients enrolled from July 2025 to December 2028, after providing written informed consent.

What is being measured

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

  1. overall survival

    OS was defined as the time from enrollment to death due to any cause. Participants without documented death at the time of the final analysis were censored at the date of the last follow-up.

    Measured: 24months

Questions about this trial

What is this clinical trial studying?

An observational study of Mucosal Melanoma of the Head and Neck and Oral Melanoma, run by Shanghai Ninth People's Hospital Affiliated to Shanghai Jiao Tong University at 1 site 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 6 inclusion and 7 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: opening soon, as of the sponsor's last update on 23 Jun 2026. 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 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 Guoxin Ren MD, MD (13916948812, renguoxincn@sina.com), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

overall survival (time frame: 24months). 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 23 Jun 2026; AzTrials last refreshed its copy on 31 Oct 2026.
