In this episode of Lab Medicine, hear a discussion on the clinical application of genomic array testing for human cancer, focusing on its benefits and limitations. Also briefly introduced is the updated research on breast cancer and rare disseminated tumor cells of the prostate using genomic array testing technology. Genomic array testing has recently transitioned from research laboratories into clinical practice. It has demonstrated clear clinical utility with high sensitivity and specificity. Similar to conventional cytogenetics, genomic array testing surveys the whole genome in an unbiased manner for clonal abnormalities which are important for diagnosis, prognosis and treatment of cancer. In addition, the unprecedented high-resolution provided by this technology helps significantly improve the diagnostic yield. Without the requirement for dividing cells, genomic array testing opens the door for chromosomal and genomic analysis of solid tumors as well as leukemia and lymphomas.
