Trial summary

This study is a prospective, cross-sectional observational single centre study to assess the feasibility of intra-operative Cerenkov Luminescence Imaging (CLI) of breast cancer wide local excision (WLE) specimens and dissected lymph nodes. The samples will be imaged using the LightPathTM Imaging System. Read more about this study

About this study

Official title: A Pilot Study to Evaluate Cerenkov Luminescence Imaging for Measuring Margin and Lymph Node Status in Breast Cancer Surgical Specimens

This study is a prospective, cross-sectional observational single centre study to assess the feasibility of intra-operative Cerenkov Luminescence Imaging (CLI) of breast cancer wide local excision (WLE) specimens and dissected lymph nodes. The samples will be imaged using the LightPathTM Imaging System. The LightPathTM Imaging System which consists of a light-tight box on which are mounted an ultra-sensitive lens and radiation-shielded camera. This study will measure the correlation between margin status of the WLE specimen and the metastatic status of dissected lymph nodes as determined by the LightPathTM Imaging System and by histopathology. This is a pilot study to assess feasibility before proceeding to a pivotal study to evaluate the benefits of the LightPathTM Imaging System in clinical practice.

Read the detailed description

Subject's blood glucose level will be measured on the day of surgery. Subjects with a blood glucose level < 12 mmol/l receive an intravenous injection of 5 MBq/kg, up to a maximum 300 MBq of 18F-fluorodeoxyglucose (18F-FDG) prior to surgery. Breast cancer surgery will be performed per standard of care. SLNB will be performed using a dose of 150 MBq technetium 99 (99mTc) nanocolloid and patent blue dye. The resected WLE specimen and lymph nodes will be imaged in the LightPathTM Imaging System. A member of the research team who is not the operating surgeon will capture LightPathTM images intra-operatively.

Prior to CLI, the WLE specimen will be placed in a specimen holder. CLI is performed according to the LightPathTM Imaging System instructions for use. All CLI will be performed between 1 and 3 hours post injection of 18F-FDG.

The WLE specimen will then undergo standard of care histopathological analysis with a positive margin defined as either invasive carcinoma or ductal carcinoma in situ (DCIS) within 2mm of the specimen surface. Lymph nodes will also be examined according to standard of care histopathological analysis.

The CLI results will not be used to influence any surgical or clinical decision-making.

All staff in the operating theatre and the recovery area caring for the patient, and pathology staff processing surgical specimens will wear badge dosimeters. Staff handling surgical specimens will also wear ring dosimeters.

What is being measured

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

  1. Tumour margin status of the Wide Local Excision specimen as determined by the LightPathTM Imaging System

    Measured: Intra-operative

Secondary outcomes (3)
  1. Metastatic status of dissected lymph nodes as determined by the LightPathTM Imaging System

    Measured: Intra-operative

  2. Radiation dosimetry to operating theatre, recovery area and pathology staff

    Measured: Up to 24 hours after injection of radiopharmaceutical

  3. Ease of use of the LightPathTM Imaging System

    Measured: Intra-operative

Questions about this trial

What is this clinical trial studying?

An observational study of Breast Cancer, run by Lightpoint Medical Limited 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 3 inclusion and 6 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 10 Aug 2016. 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 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?

Tumour margin status of the Wide Local Excision specimen as determined by the LightPathTM Imaging System (time frame: Intra-operative). 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 NCT02037269, 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 10 Aug 2016.
