  • Research summary

    Research question: ‘Is there a statistically significant difference between CTR expression in the tissue of patients with MM compared to that of patients without MM?’

    MM is a malignancy of the plasma cells. The role of the CTR in MM is not fully understood. It is thought that CTR over-expression is induced within the tumour microenvironment in the tissue of patients with MM, even at low level disease. Immunohistochemical (IHC) staining is used to investigate this hypothesis.

    IHC is a technique whereby tissue constituents, termed ‘antigens’ are identified using antigen-antibody interactions; the site of interaction is visualised using a labelling system.

    Case and control (n = 30 per group) BMT/soft tissue specimens will be stained with anti-CTR and anti-CD138 antibodies. The results will be analysed to determine the CTR-positive percentage staining of the tumour microenvironment. Statistical analysis will determine if there is a significant difference in the CTR-positive staining between the two groups. We hypothesise that CTR over-expression is seen in the tissue of patients with MM compared to a control group. Therefore the CTR can potentially be used as a diagnostic marker for MM. A confirmed hypothesis would indicate a benefit to patients with a low tumour load and in terms of allowing earlier treatment. The CTR could also serve as a potential, novel imaging, monitoring or therapy target.

    The aims of the project are to demonstrate:

    1. A correlation between CTR expression and MM.
    2. A correlation between CTR expression and MM disease burden.
    3. That CTR over-expression can be used as a diagnostic marker for MM.

    The study will be conducted at King’s College Hospital over approximately 3 months. Funding will be provided by Viapath and/or Bloodwise.
