ERBB2 and gastric cancer: Recently, it was shown that comparing the results of the NanoString CNV panel (20-gene signature for copy number value detection) with the best ways to measure gene expression, like IHC analysis and in-situ hybridization (FISH), showed a good level of agreement (κ-value = 0.35) in the HER2 copy number variation from biopsy gastric cancer tissues (FFPE blocks) with the results of IHC/FISH, which had sensitivity and specificity values of 66.7% and 85.2%, respectively [62].
