Collection Instructions

Collection Instructions:

Routine Small and Medium Sized Specimens
  1. Collect Tissue specimen and place into a Sterile Container with enough 10% formalin to cover the tissue by at least 2 - 3 inches.
  • Specimens must contain a region with at least 20% tumor
  • Breast Specimens: Immerse in fixative within 1 hour of biopsy or resection procedure for optimum tissue processing. Document the time that the tissue was placed into formalin.
  • Suspicion of Lymphoma: Send FRESH. Do NOT place specimen into formalin.
*Must state that lymphoma protocol is needed on requisition
 
  1. Specimens should be delivered to the Surgical Pathology Lab as soon as possible.  If delivery of a resection specimen to the Surgical Pathology department is delayed (e.g. specimens from remote sites), the tumor should be bisected prior to immersion in fixative.
  • It is important that the surgeon ensure that the identity of the resection margins is retained in the bisected specimen
  • Alternatively, the margins may be separately submitted
  1. Ensure that the cap is tightly secured on the Collection Container
  2. The time of removal of the tissue and the time of immersion of the tissue in fixative should be recorded and submitted to the laboratory

Routine Large Sized Specimens
  1. Collect tissue specimen and place in large leak-proof container
  2. Bring specimen to the Surgical Pathology laboratory immediately, or refrigerate

Specimen Container Labeling Instructions:
  1. Specimen Containers submitted to Surgical Pathology must be labeled with the following patient information:
  • First and Last Name
  • Date of Birth
  • Medical Record Number
  • CSN Number
  • Name of Specimen Site/Source
*If more than one site is sampled, a separate collection container must be submitted for each site
 
  1. Check all labeling of containers prior to leaving the collection site
 
  1. Place the following in a biohazard bag for transport to the Surgical Pathology Lab:
*If more than one site is sampled, all specimen material collected must be packaged and separated according to specimen site
 
  • Specimen Containers
  • Specimen Requisitions

Processing Instructions:
  1. Formalin Fix fresh tissues in 10% Neutral Buffered Formalin
  2. Paraffin-embed the fixed tissue and prepare FFPE Tissue Block
  • Specimens must contain a region with at least 20% tumor
 
  1. Protect specimen from excessive heat and transport one of the following to the Clinical Genomics Laboratory for testing:
  • Tissue Block
    • Tissue block will be returned to the Surgical Pathology Lab after testing
  • 5 - 10 unstained 5 micron sections on slides
    • Place slides into a protective container
     
 
  1. Include the Surgical Pathology report with the specimen

By Report

Interpretive Data

Refer to report for result specific interpretation details

Panel content includes multiple variant types, including single nucleotide variants (SNV), deletions and insertions, copy number variants (CNV), translocation and splice variants, microsatellite instability (MSI) and tumor mutation burden (TMB), crossing 523 cancer-relevant genes from DNA and 55 genes from RNA.

Key DNA and RNA biomarkers cover malignancies of lung, melanoma, colon, ovarian, breast, gastric, bladder, prostate, brain, and sarcoma. By characterizing the genomic profile of solid tumors with TSO500, the resulting mutation profile can be used to guide treatment as well as offer insights into diagnosis or prognosis. Ultimately, these data help clinicians prevent, detect, and treat cancer.
