dc.description.abstractFluorescence in situ hybridization (FISH) has been known to be the most representative and standardized test for assessing gene amplification However. FISH requires a fluorescence microscope, the signals are labile and rapidly fade over time. Recently, chromogenic in situ hybridization (CISH) has emerged as a potential alternative to FISH The aim of this study is to test the reliability of CISH technique for the detection of epidermal growth factor receptor (EGFR) gene amplification in non-small-cell lung carcinomas (NSCLC), to compare CISH results with FISH. A total of 277 formalin-fixed and paraffin embedded NSCLC tissue samples were retrieved nom the surgical pathology archives at Seoul National University Bundang Hospital CISH and FISH examinations were performed to test EGFR gene amplification status There was high concordance in the assessment of EGFR gene copy number between CISH and FISH tests (Kappa coefficient = 0.83) Excellent concordance was shown between two observers on the interpretation of the CISH results (Kappa coefficient = 0 90) In conclusion, CISH result is highly reproducible, accurate and practical method to determine EGFR gene amplification in NSCLC In addition, CISH allows a concurrent analysis of histological features of the tumors and gene copy numbers.
