The Charles Day Tissue Bank (CDTB) was established in 2012 to facilitate research into haematological malignancies and other blood disorders. The collaboration between Sir Charles Gairdner Hospital (SCGH) and PathWest Laboratory Medicine WA is supported by the Day family and the Charlie’s Leukaemia and Lymphoma Fund and has to date, over 10,000 samples in storage. Currently patients from SCGH and Fiona Stanley Hospital undergoing a bone marrow biopsy for diagnostic testing are consented. Bone marrow and peripheral blood samples are taken for cell processing prior to storage in liquid nitrogen or at -80°C . This unique biospecimen collection includes viable peripheral blood and bone marrow mononuclear cells, serum and tissue samples. Currently however, our utilisation rate is low, and samples are mainly released for further diagnostic testing requirements. The Openspecimen Biospecimen Management System has recently been implemented and we aim to focus on the utilisation of these valuable samples. This poster will showcase the Charles Day Tissue Bank including the standard processes, range of samples available and how these samples can be accessed to facilitate research in haematological cancers and related diseases.
