2
H & E SLIDES
  • Stained tissue on glass slide.


  • Required for every case entered on a protocol for central review.


3
H&E SLIDES
  • RESOLUTION
  • Re-cuts
  • Must have adequate tissue to show tumor.
  • PROBLEM
  • Pathology departments tend to be possessive of H&E slides.
4
PARAFFIN BLOCKS
  • The manner in which biopsies are preserved.


  • Verify the block/blocks submitted includes a portion of the tumor used for diagnosis.


  • Required on most protocols.
5
PARAFFIN BLOCKS
  • PROBLEM
  • Pathology departments tend to be possessive of paraffin blocks.


6
PLUG SAMPLES


  • method uses derm needle to remove selected tumor area from paraffin block.
7
PLUG SAMPLES
  • Request a Specimen Plug Kit.


  • Kit contains shipping tube and derm needle.



8
PLUG SAMPLES
  • Ask pathologist to select tumor area.


  • Use the derm needle to punch the selected area from the specimen block.
9
PLUG SAMPLES
  • Label needle with specimen ID.
  • Place derm needle into specimen shipping tube, without removing specimen from needle.


10
PLUG SAMPLES
  • Allows your pathology department to keep their original block, while submitting a tissue sample to us for banking.
11
DISADVANTAGES OF UNSTAINED SLIDES
  • Easily broken during shipment
  • Slides become negative for antibody detection in a short time
  • Difficult to store
  • Limited amount for staining
  • Cannot make tissue arrays from slides


12
ADVANTAGES OF PARAFFIN BLOCKS
  •  Easy to store, no freezer necessary
  •  Hundreds of samples are possible
  •  Not broken in shipping
  •  Antibodies are preserved
  •  Tissue Microarrays are made from paraffin blocks
13
TISSUE ARRAYS
  • Allows a pathologist to look at many different tumor sections at once.
  • Helpful in finding common markers in hundreds of patients using only 1 slide, instead of hundreds of slides.
14
TISSUE ARRAYS
  • Core sample removed from specimen block.
  • Inserted into blank paraffin block.
  • Repeated until block is filled with rows of specimens, each representing a different case.
15
TISSUE ARRAYS


  • Grid chart used for documenting the specific location of each specimen.
16
TISSUE ARRAYS
  • Sections are cut from array block, and placed on glass slides.
  • Slides stained for pathologist review.
17
PATHOLOGY
  • Share letter written by Dr. Hammond to announce the funding of the tissue repository by the NCI.



  • Explain that patient is participating in research study and has given written permission.
18
 REIMBURSEMENT
  • Only offered for submissions which can be used for more than current study.


  • $200 Block / blocks submitted with tumor.
  • $200 Plug sample from the block, must contain tumor
  •  $300 Blood, Serum, complex materials.
  • No reimbursement for H&E only submissions.
19

SUBMISSION REQUIREMENTS
  • TISSUE (H&E, blocks, plug samples).
  • One or all may be required per protocol.
  • Pathology Report.
  • Always required.


  • RTOG Pathology Submission Form.
  • Always required when tissue is being submitted.
20
PATHOLOGY SUBMISSION FORM
  • MUST  check appropriate box on submission form to specify level of patient consent.
  • Do not send me copy of patients consent.
21
OUTSIDE HOSPITALS AND LABORATORIES
  • Make sure they understand importance of including paperwork with the pathology material.
22
PLEASE GO OUT OF YOUR WAY TO MAKE SURE THAT I RECEIVE EVERYTHING NECESSARY TO PROCESS YOUR PATHOLOGY MATERIAL!
23
WHAT HAPPENS TO TISSUE SUBMISSIONS
  • Every piece of paper, every slide and every block is marked with protocol and case number.
  • Logged on sheet faxed to RTOG Headquarters.
  • Receipt information entered on calendar.
  • Send copies of paperwork which is put in patients file.
  • Tissue is filed until sent to pathologist or for future study.
24
SENDING TISSUE TO PATHOLOGIST
  • Periodically or when requested, material is sent to pathologist for central review or for a research study.


  • I am responsible to collect and send the following material:
    • Slides
    • Pathology report
    • Review form

25
DATABASE
  • Our database allows us to account for disclosure of all information.
26
RTOG TISSUE REPOSITORY
  • A great resource for even more studies in the future.
  • To date the tissue bank has currently collected:
        •   17,251 Cases
        •   51,410 H & E’s
        •   16,360 Blocks
