Biorepositories for NCI-Sponsored Cancer Clinical Trials

Specimen Types

The CGB obtain biospecimens from patients entered on cancer clinical trials supported through the NCI’s Clinical Trials Cooperative Group Program. Typically these are large phase II or phase III therapeutic trials and the specimens are associated with detailed, clinical and outcome data. The anatomic site and type of specimen(s) collected vary based on the scientific goals of the trial.

Examples of banked biospecimens include:

Protocol-specific information for Cooperative Group cancer clinical trials under which most specimens were collected can be found at and/or by querying the group bank responsible for biospecimen procurement for the trial.
