About this study

Official title: Efficiency of Presurgical Basal Cell Carcinoma Margin Mapping Using Optical Coherence Tomography

This Interventional Randomised Controlled study is intended to establish that presurgical margin mapping of BCCs with OCT results in a reduction of the number of MMS surgery stages without adversely impacting clinical outcome, resulting in shorter patient stays and more efficient use of surgical and operating room resources.

Read the detailed description

Basal Cell Carcinoma (BCC) is the most common malignancy in humans. Its incidence is continuously increasing. The head and neck areas are most commonly affected due to their increased lifetime exposure to sun compared to other body parts. BCC is often treated by surgical excision which has high cure rate compared to other treatment modalities, but leaves a visible scar which can affect the quality of life of the patient, depending on the location and size of the excision. Mohs Micrographic Surgery (MMS) was developed to minimize the size of the surgical excision whilst maintaining very high cure rate. The main drawback of MMS is that repeated surgery procedures are usually required to eliminate all of the tumour using specialist resources located at the clinic.

Optical Coherence Tomography (OCT) allows non-invasive in-vivo imaging of superficial skin lesions. It is in routine clinical use for diagnosis of BCCs, and the diagnostic sensitivity and specificity is well established in published multi-centre trials. A further potential application of OCT is the pre-surgical mapping of the lateral margins of BCC. If the margins of a BCC were accurately known prior to commencing an MMS treatment, the treatment could be performed much more quickly, resulting in shorter patient stays and more efficient use of surgical and operating room resources. Previously published research has already shown that OCT mapping of BCC margins is more accurate than clinical assessment; the objective of the present study is to demonstrate that pre-surgical mapping of BCC margins with OCT is also more efficient.

What is being measured

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

  1. Average number of Mohs stages

    Is the average number of Mohs stages < 1.4 with a 95% confidence level. (P < 0.025)

    Measured: 1 day

Secondary outcomes (2)
  1. Size of the surgical defect

    Validate that the reduction in MMS stages by use of OCT mapping does not result in an increase in the size of the surgical defect

    Measured: 1 day

  2. Average time taken to perform OCT margin mapping

    Show that the average time taken to perform OCT margin mapping is < 5 minutes for lesions of area < 2 cm2

    Measured: 1 day

Model description
Participants are randomly assigned to two arms. Participants in the first arm receive Mohs surgery using OCT mapping to delineate tumor margins. Participants in the Control Arm receive Mohs surgery using clinical estimation of tumor margins (ie. standard care) The average number of Mohs surgery cycles will be compared for the two arms.

Questions about this trial

What is this clinical trial studying?

A study testing OCT Mapped in people with Carcinoma, Basal Cell, run by Michelson Diagnostics Ltd. at 1 site in United Kingdom.

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 1 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: stopped early, as of the sponsor's last update on 28 Jan 2020. 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 United Kingdom. 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 was stopped early (reason given: Funding exhausted. Sufficient data already collected.). Results are not available in the source record.

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?

Average number of Mohs stages (time frame: 1 day). 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 28 Jan 2020; AzTrials last refreshed its copy on 1 Nov 2026.
