Flow on FNA/Core Project- Faster Diagnosis for Lymphoma: Utilising Flow Cytometry on FNA Samples of Lymph Nodes to Diagnose Lymphoma in Hours, Not Days. (Flow on FNA)

The patient will undergo a standard of care procedure including FNA (fine needle aspirate) and core biopsy, which are used during the cancer pathway journey to provide diagnosis. However as described, this pathway can take several weeks to reach a diagnosis. Thus, the project is aimed at shortening the time to diagnosis. To achieve this additional samples will be taken at the time of the above procedures. Typically, during an FNA a liquid sample is taken and spread on slides, but additional sample will be placed in a test tube for this project. During core biopsies, typically 3 to 4 cores are taken, and for this project an additional liquid sample will be placed in the test tube, from the same biopsy site. Therefore, for the patient there is no additional procedure, but additional time (less than one minute) will be needed for the operator to perform the additional steps.

The sample taken for this project will then be sent to the HODS laboratory for supplementary processing above standard of care. Flow cytometry, a standard procedure performed on blood samples, and other biological fluids, will then be performed on the project sample. The immunophenotyping is UKAS accredited, but this project will not be at this time, which will be clear on the report, as this is a research sample. However, results which will come back within hours to 1-2 days, will be used by the clinical teams to help guide further tests. The whole pathway will be evaluated and audited, to assess the hypothesis that patients will be diagnosed faster within the cancer pathway.
