About this study

Official title: Nevoid Basal Cell Carcinomas in Young People With Gorlin Syndrome

The overall aim of the project is to gain knowledge about the expected course of nevoid basal cell carcinomas and the usefulness of dermatoscopy in young individuals with Gorlin syndrome.

Clinical experience and some case-reports suggest that nevoid basal cell carcinomas have an indolent course with slow growth and that they can sometimes regress. However, no systematic research has previously been performed.

Increased knowledge about nevoid basal cell carcinomas and the use of dermatoscopy could be of great clinical value in the follow-up and treatment of individuals with nevoid basal cell carcinoma syndrome.

What participants receive

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

  • Active surveillanceOther

    Skin lesions clinically compatible with nevoid basal cell carcinomas are documented with measurements, clinical description, clinical photos and dermatoscopy photos every eight months for two years. Three representative skin lesions are selected at the first visit to be removed by skin biopsy at the end of the observation period (two years) for histopathological analyses.

    If a nevoid basal cell carcinoma shows a certain increases in size (according to pre-specified criteria of the study protocol), ulcerates, gets unevenly demarcated or give functional complaints during the observation period, the skin lesion will be excised.

What is being measured

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

  1. Nevoid basal cell carcinoma size increase

    Largest diameter (measured in millimeter) of nevoid basal cell carcinomas after two years surveillance compared to at baseline.

    Measured: Two years

  2. Dermatoscopy findings

    Dermatoscopy findings of nevoid basal cell carcinomas compared to nevoid basal cell carcinoma size increase.

    Measured: Two years

Secondary outcomes (1)
  1. Nevoid basal cell carcinoma histology

    Histological analysis, including immune histochemistry, of skin biopsies obtained from representative nevoid basal cell carcinomas.

    Measured: Two years

Questions about this trial

What is this clinical trial studying?

An observational study of Basal Cell Carcinoma and Gorlin Syndrome, run by Oslo University Hospital at 1 site in Norway.

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 3 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: finished, as of the sponsor's last update on 9 Oct 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 Norway. 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?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

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?

Nevoid basal cell carcinoma size increase (time frame: Two years). The study lists 2 primary outcomes in all. 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 9 Oct 2026.
