Cancer Microarray

Test name: Cancer Microarray
Also known as: Cancer Array


Indications:  Hematologic malignancies, specifically AML, ALL, CLL, CML and NHL


Test Information:

  • Cancer Microarray is a test following (or used in conjunction with) chromosome analysis and/or FISH of diagnostic bone marrow, cancer blood, lymph node, or tumor tissue specimens
  • A SNP/oligo platform assesses copy number changes in over 1,200 cancer-related genes and identifies copy neutral loss of heterozygosity (cnLOH) within tumor-suppressor gene regions
  • This assay is particularly helpful with specimens with low mitotic index due to the disease
  • This assay is unable to detect balanced translocations, or the location of duplicated or rearranged segments
  • Increased resolution may identify uncertain clinical findings or unexpected abnormalities unrelated to malignancy (constitutional, consanguinity)

Specimen requirements*:  Test kits are available – please contact the laboratory
*HGL will attempt to run tests on smaller volume samples

  • Bone Marrow: 3 ml bone marrow in a 3 ml sodium heparin (green top) tube
    Instructions: Bone marrow from 1st or 2nd aspirate using a sodium-heparinized syringe
  • Cancer Blood: 3-5 ml peripheral blood in a sodium heparin (green top) tube
  • Lymph Node / Solid Tumor Tissue: ≥5 mm3 of lymph node or representative tumor tissue in culture media
  • Paraffin Embedded Tissue: 5-10 dissected cores from selected malignant region
