Although Break-Apart ALK fluorescence in situ hybridization (FISH) is a reliable diagnostic method for detecting ALK gene rearrangement, it is too costly and time-consuming for use as a routine screening test. Our aim was to evaluate the clinical utility of a novel rapid FISH (RaFISH) method developed to facilitate hybridization. RaFISH takes advantage of the non-contact mixing effect of an alternating current (AC) electric field. Eighty-five specimens were used from patients diagnosed with NSCLC identified immunohistochemically as ALK 0, (1/2+) or (3+). With RaFISH, the ALK test was completed within 4.5 h, as compared to 20 h needed for the standard FISH. Although RaFISH produced results more promptly, the staining and accuracy of the ALK evaluation with RaFISH was equal to the standard. We found 97.6% agreement between FISH and RaFISH based on the status of the ALK signals. These results suggest RaFISH could be used as a clinical tool to promptly determine ALK status.}, title = {Novel method for rapid fluorescence in-situ hybridization of ALK rearrangement using non-contact alternating current electric field mixing}, volume = {7:15116}, year = {2017} }
