Tissue collected under DTC tissue procurement protocol 06-C-0213 will not be used or tracked. Sample location and use will be managed in the Repository at the Frederick National Laboratory for Cancer Research using LabMatrix software. Patients may remain on this longitudinal protocol for the duration of their consent.
