Trial summary

Lymphoma diagnosis often involves removal and biopsy of one or more lymph nodes. Many (around half) of these diagnostic procedures show that no cancer is present, hence unnecessary removal results in numerous side effects and complications. The procedure is also highly invasive.

Study population: Patients undergoing surgical head \& neck lymph node biopsy within Gloucestershire Hospitals NHS Foundation Trust Patients with a lump in their head or neck are sometimes referred by their GP for a biopsy. This often first involves taking a small sample of cells with a fine needle, guided by ultrasound, called a Fine Needle Aspiration (FNA) biopsy. If the result from this FNA biopsy is inconclusive, then they are often further referred for a surgical biopsy. Gloucestershire Hospitals NHS Foundation Trust is a tertiary referral centre for surgical head and neck biopsies.

Who may be able to join

  • Patients undergoing biopsy or excision of lymph nodes as part of their routine clinical care within Gloucestershire Hospitals NHS Foundation Trust.
  • Patients undergoing lymphadenectomy as part of routine treatment

Who cannot join

  • Patients unable to consent to the study due to communication difficulties
  • Patients unable to consent to the study due to lack of capacity

About this study

Official title: Diagnosis Of Lymphoma In Vivo Using Vibrational Spectroscopy (Ex Vivo Phase)

Lymphoma diagnosis often involves removal and biopsy of one or more lymph nodes. Many (around half) of these diagnostic procedures show that no cancer is present, hence unnecessary removal results in numerous side effects and complications. The procedure is also highly invasive.

The investigators have already shown that it is possible to tell the difference between healthy and diseased tissue in the laboratory by looking at the light emitted by tissue when a low power laser is shone on to it. The investigators intend to use this technique, known as "Raman Spectroscopy" (RS) to tell if tissue in the node is cancerous or healthy. By combining RS with a fine needle, the technique can target tissues below the skin with minimal invasion. Our needle will provide the clinician with instant diagnosis without the delay and cost of a laboratory analysis by pathologists.

The investigators have designed a probe that slides through a fine needle, guided by ultrasound, to the lymph node. The space between the two needles provides space for cell aspirate.

The investigators propose to measure spectra from excess lymph node biopsy samples taken during standard routine diagnostic biopsy.

The investigators are also interested to see if they can successfully extract a fine needle aspiration (FNA) biopsy sample using the device, as well as record a RS measurement. If successful this would ease clinical adoption as the study could run in parallel with existing standard routine clinical practice, using just one device.

This study will evaluate the new device on half a lymph node that will be excised and snap-frozen during a routine surgical biopsy, to gather data for submission of approvals for an in-vivo study to follow.

Read the detailed description

Surplus lymph node tissue collected from patients undergoing routine surgical treatment for head \& neck disease will be investigated using vibrational spectroscopy.

The project will develop a combined FNA/Raman spectroscopy needle probe. This study will evaluate this device on excised lymph node tissue to gather data for submission of approvals for an in-vivo study to follow. Raman \& FTIR (fourier transform infrared) spectra will be correlated with routine histopathology results using multivariate analysis methods. Cytology samples taken using the device will be compared with histopathology results.

Aims

To demonstrate that the FNA/Raman spectroscopy probe device, developed as part of this project, can:

Safely perform measurement of Raman spectra on excised lymph node tissue Safely perform FNA (fine needle aspiration) biopsies on excised lymph node tissue To evaluate the performance of a Raman needle probe to detect lymphoma \& malignancy in excised head \& neck lymph nodes and differentiate from benign nodes.

To develop the investigators understanding of vibrational spectroscopy signal characteristics in head \& neck lymph nodes (through Raman \& FTIR mapping measurements of tissue sections).

Objectives To test a new combined FNA and spectroscopic device on ex vivo tissue in preparation for an in vivo study.

Outcome

Primary Outcome Measures The FNA/Raman spectroscopy probe device can be used safely on excised lymph nodes to measure tissue spectra and collect FNA biopsies.

Diagnostic performance of vibrational spectroscopy for differentiation of lymphoma \& malignant nodes from benign nodes.

Questions about this trial

What is this clinical trial studying?

An observational study of Lymphoma and Head and Neck Cancer, run by University of Exeter 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 2 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 11 Jun 2024. 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?

Safe spectroscopic measurement (time frame: 3 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 11 Jun 2024.
