Background:

Knight Diagnostic Laboratories have an extensive menu of probes for hematologic and solid tumor analyses by fluorescent-in situ-hybridization (FISH) techniques.  Karyotypic analysis and FISH testing are key components in the diagnosis of hematologic malignancies. Recently, FISH has become an essential component in therapeutic decisions for solid tumor patients as well.  Tests are developed quickly after clinical utility has been established.

Methodology:

Slides are prepared per standard protocols and 100-200 interphase cells are scored for each probe under fluorescence microscopy.  FISH can also be performed on sections of formalin-fixed, paraffin-embedded tumor tissue; slides are prepared per standard protocols and 100 interphase cells are scored.  For tumor samples on FFPE, testing includes a pathologist review of each tumor slide prior to FISH testing.  For multiple myeloma, blood or bone marrow cells are sorted on CD138+ prior to FISH.

Specimen Requirements:

Bone Marrow: 
Shortly before aspiration add 0.2 cc of Sodium Heparin (1,000 units/ml) to tube of transport medium (please contact lab to arrange for transport medium to be sent).  Add at least 1 cc of bone marrow aspirate to the tube and suspend well.  Allow no clots to form.

Peripheral blood:
May be used if bone marrow is inaspirable and blasts (.5%) are present.  Send in Sodium Heparin tube.

Bone core biopsy:
May also provide cells in cases where marrow is severely packed.  Send in transport medium with Sodium Heparin.

Bone marrow smears:
Provide 10 slides

Formalin-fixed paraffin-embedded tumor block or FFPE slides:  

  • If sending slides, please include H&E stained slide cut from same block
  • Preferred slice thickness is 4-5 microns on positively charged slides.
  • Please submit 3-5 slides. Store at room temperature.
  • Contact Client Services at (855) 535-1522 for shipping supplies and instructions

Additional Info:

The Knight Cancer Institute at Oregon Health & Science University is a pioneer in the field of precision cancer medicine. The institute's director, Brian Druker, M.D., helped prove it was possible to shut down just the cells that enable cancer to grow. This breakthrough has made once-fatal forms of the disease manageable and transformed how cancer is treated. The OHSU Knight Cancer Institute is the only National Cancer Institute-designated Cancer Center between Sacramento and Seattle – an honor earned only by the nation's top cancer centers. It is headquarters for one of the National Cancer Institute's largest research collaboratives, SWOG, in addition to offering the latest treatments and technologies as well as hundreds of research studies and clinical trials.
