Castle Clinical Sample Repository

Free program allows patients to take advantage of future advances

If you have chosen to take the DecisionDx™-UM gene expression profile (GEP) test, it is important to know that Castle offers a tissue repository, which gives patients the option to have an additional sample of their tumor tissue stored for future use. Your doctor can collect the extra tissue at the same time as your biopsy procedure and send to Castle along with the sample required for the GEP test.

castle_logoThe health care team at Castle Biosciences offers the Castle Clinical Sample Repository program free of charge to all DecisionDx-UM patients. We are strong believers in the power of personalized medicine, and with its rapid advancements, a patient’s ability to take advantage of new targeted treatments, clinical trials, and further prognostic testing as they become available. The samples will be stored for five years and can only be released for use by patient request. Castle will not use the samples for its own research purposes.

Tissue Repository Addresses Important Need in Uveal Melanoma

Uveal melanoma is one of the few cancers that can be diagnosed in the doctor’s office, rather than through a biopsy procedure and tissue analysis by a pathologist. This means that, unless the eye is removed rather than treated with radiation, there is typically no tumor tissue to store or any guidelines that would require it. The clinical sample repository addresses an important need in this disease.

If you are interested in accessing the repository service, you must talk to your physician. If you choose to provide a sample for storage, you will be required to review and sign a form titled “AUTHORIZATION FOR STORING BIOSPECIMEN FOR POSSIBLE FUTURE USE.” Your doctor will discuss the sample collection process with you, which would occur at the same time your sample for DecisionDx-UM testing is taken. The sample for storage, along with the required authorization, will be provided to Castle via our standard shipping process. Samples for storage will not be accepted without a completed authorization.

Know your TYPE, Know your RISK
You’ve just been diagnosed with uveal melanoma, and it’s important to know that there is a test that can identify your tumor type—and the risk of your cancer spreading.

GETTING TESTED       Timing is Critical
To know your tumor type and risk, a biopsy must be taken BEFORE radiation treatment.
