Tell us what you're looking for so we can start searching for eligible samples. 

Repository sample request form

Step 3: Cases identified by our team

Step 3: Cases identified by our team

We'll identify cases using data captured by our team 

  • Specimen (tissue) type.
  • Tissue status (MAL, MET, etc.).
  • Specimen format.
  • Sample age.
  • Sample matching (FFPE + frozen pair, MAL + NAT from same subject, tissue + blood).

Step 4: Chart review

Step 4: Chart review

Chart reviews are done manually by our team or in collaboration with CTSI’s informatics team (BPIC)

  • Final pathology diagnosis.
  • Treated/untreated.
  • Therapeutics (specific or general class).
  • Receptor or mutation status.
  • Clinical diagnosis.
  • Recurrence/refractory.

Step 5: Preliminary results shared

Step 5: Preliminary results shared

  • Investigators receive a spreadsheet of preliminary results (list of all possible cases that meet study criteria).
  • "Preliminary" indicates samples must go through quality control (QC) to confirm status and quality.
  • Investigator chooses which samples go through QC.

Step 6: Pathologist QC

Step 6: Pathologist QC

  • Tissue status (diseased, normal, malignant, normal adjacent, or benign).
  • QC diagnosis/comments (at discretion of pathologist, additional details that may be helpful to determine if/how sample should be used for research).
  • Viable neoplasia percent.

Step 7: Final results shared

  • Investigator reviews QC results and chooses samples for distribution. 
  • We provide a limited dataset that goes back one year prior to surgery and includes: 
    • Basic demographics
    • Pathology reports
    • Medication list
    • Social history
    • Medical history
    • Treatment history
    • Lab tests
    • Surgical procedure
    • Sample info

How we collect archived samples

How we collect archived samples

We adhere to best practices every step of the way.

Screening and consent

  • Review surgical schedule for procedures that would yield excess clinical tissue.
  • Screening process based on current research needs from investigator protocols and fresh tissue procurement requests.
  • Informed consent for excess tissue, optional biofluids, and optional sensitive health information.

Procurement

  • Tissue chain of custody: surgical tissue is released to Pathology for patient clinical care, tissue deemed excess by Pathology is released to us.
  • Tissue is processed and samples are de-identified.
  • Honest broker: We act on behalf of researchers to collect and distribute de-identified specimens.
  • Investigator protocols and fresh tissue needs are prioritized.

Biobanking

  • Only tissue in excess of investigator and fresh needs are collected for our repository.
  • Sample, patient, and some clinical data are maintained in BSI (specimen tracking software).
  • Honest broker: We maintain the key to patient identity in order to link samples back to the EHR.
  • Review and approve sample requests for retrospective studies.
  • Perform chart review to determine eligible samples.

Step 2: We review your request

Step 2: We review your request

Our team will review your request and get back in touch. We may ask to schedule a kick-off call to discuss.

Before we can begin working on your request, we’ll need:

  • A fully signed tissue procurement agreement, which details the project’s scope of work. Allow at least two weeks for this to be developed once the protocol has been sent.
  • Your project to be approved in the CTR Portal and configured for invoicing.

At this point, your project will be “active.”

Step 3: Complete the specimen procurement request form

Step 3: Complete the specimen procurement request form

Each time you’d like to request a collection on a scheduled procedure, download this form and send it to our procurement team:

Only complete this form if:

  • Your project has been registered in the CTR Portal.
  • Your request has been accepted.
  • A tissue procurement agreement has been finalized.
