Starts With Proper Collection and Storage

< Previous SectionNext Section >

Genome-wide profiling requires proper sample collection and storage. This is why biopsy specimens must be collected, stored, tracked, and used according to the highest scientific and ethical standards.

Informed consent for use of cancerous biopsy specimens (or a waiver of this consent) must be in place at the time of collection.

Samples must be given an electronic, unique identifier that links the specimen to a patient, to a treatment protocol, and to the informed consent (or waiver).

Samples must be stored and retrieved following best clinical practices.

When all this is in order, a researcher can use the biopsy sample to get a genome-wide profile of the cancer.

Graphic shows that proper care of a tissue sample. It shows a clinician getting informed consent from the patient before removing a tissue sample, removing sample, adding barcode identifier to the container holding the sample, storing sample carefully in liquid nitrogen, carefully thawing the sample before analyzing it, and carefully refreezing any remaining tissue sample.
