PG - 463-5 AB - The time required to count signals in the detection of HER-2/neu gene amplification in breast cancer by fluorescence in situ hybridization (FISH) has been a problem. To assess whether the amount of time necessary for counting could be reduced, image analysis using computer software (Win ROOF) was tested. Five photographs from each FISH sample were arranged into ten composite photographs. All ten composite photographs were necessary when using the conventional method of manual counting. However, using only four of the composite photographs and the image analysis method, the 60 necessary nucleus numbers could be measured, and a constant ratio of HER-2/neu / CEP 17 was obtained. In all 58 samples used, in the presence or absence of HER-2/neu gene amplification, there was agreement in counts between the conventional and image analysis methods, and a good correlation of r=0.961 (p<0.001) was obtained. Using the image analysis method, the necessary scoring time was reduced, particularly when the HER-2/neu gene had been amplified, where it was completed in about 1/4 of the time normally required. These results indicate that this image analysis method can be applied when using FISH in other areas of research, and may increase the speed of examination.
