Why set up a NET biobank? Garbage in…… Diamonds in……
Governance Infrastructure Human Tissue Authority licence – prospective research tissue bank – framework and guidelines – allows satellite sites Research Ethics Committee approval R & D approval in each participating Trust
Management Infrastructure Policies and Procedures – Quality management system – Risk register – Disaster recovery plan – Incident log
Management Infrastructure Standard Operating Procedures – Collection – Storage – Processing – Equipment Robust tracking system Sample and data audits
What to collect?
Specialised samples Blood (circulating tumour cells, DNA, RNA, miRNA) Metastatic biopsies Cells from ascites/pleural effusions Carcinoid heart valves
Quality Assurance – FF tissue Sections are cut from frozen tissue and stained with haematoxylin and eosin Percentage tumour is assessed for each tumour block
Data entry and storage All samples are labelled with a 2D barcode label and scanned directly into the database to avoid transcription errors Each sample has an anonymised unique identifier Samples are then stored appropriately in the -80 o C freezer
NET Biobank Funding –Raymond and Beverly Sackler Foundation Prospectively consent and collect tissue / biological samples Robust infrastructure, HTA compliant
Benefits of banking within UCL/RFH Biobank Infrastructure Staff Resources Cheaper than going it alone Improves funding opportunities
