Biobank
Resection specimens will be fresh-frozen and formalin-fixed paraffin embedded for future molecular analyses. A blood sample (20 mL maximum) will be drawn from the venous line during the surgical procedure. This will be used as a genome reference. The processed body material is stored in the designated RALLY biobank under the management of the UMC Utrecht (in -80° C freezers or in nitrogen vessels for fresh frozen material). For participating sites, the material is first temporarily stored according to the guidelines of the respective center’s biobank. Afterwards, the specimens will be transported to the UMC Utrecht and stored in the RALLY biobank.
