INTERPHASE CYTOGENETICS OF THE BREAST TUMORS WITH FLUORESCENCE IN SITU HYBRIDIZATION (FISH) ON CYTOLOGIC PREPARATION
―ITS PRACTICE AND CLINICAL APPLICATIONS―
Fluorescence in situ hybridization (FISH) study with the chromosome specific probes is performed in the interphase nuclei of the routinely processed cytologic preparation of the breast tumors. Numerical aberrations on the chromosomes 1, 3, 11 or 17 were detected in more than 80％ of the malignant tumors, but not in the benign tumors. Marked heterogeneity of the polysomies is noted in the malignant tumor cells. A few malignant cases revealed monosomy of chromosome 17. No apparent correlation between the numerical abnormalities and the histological features in malignant tulnors is identified. These results suggest that the interphase cytogenetics with FISH for the breast tumors may be useful for differential diagnosis of malignancy. The practice and the clinical applications of the FISH study are discussed.
