Ductography and fiberoptic ductoscopy (FDS) are used to identify abnormal intraductal lesions, although it is difficult to distinguish malignant from benign cases. Therefore, we studied the clinical usefulness of fluorescence in situ hybridization (FISH) analysis of a numerical aberration of chromosomes (aneusomy) using ductal lavage from patients with nipple discharge.<\/jats:p><\/jats:sec><jats:sec><jats:title>METHODS<\/jats:title><jats:p>We applied ductography and FDS to 90 women who had nipple discharge. Ductal lavages obtained from patients with positive ductography and\/or FDS findings were subjected to cytology and FISH analysis using centromere probes for chromosomes 1, 11, and 17. Patients with samples that showed aneusomy in at least one of the three chromosomes were diagnosed as positive.<\/jats:p><\/jats:sec><jats:sec><jats:title>RESULTS<\/jats:title><jats:p>Histologic evaluation revealed 54 benign lesions and six malignancies. The sensitivity, specificity, and diagnostic accuracy were 33.3%, 88.9%, and 83.3%, respectively, for cytology and 100%, 100%, and 100%, respectively, for FISH.<\/jats:p><\/jats:sec><jats:sec><jats:title>CONCLUSION<\/jats:title><jats:p>The results demonstrated that FISH has a diagnostic accuracy comparable to cytology. This technique has 100% specificity is making a definitive diagnosis of malignancy in patients with indeterminate cytologic results, suggesting that FISH diagnosis can be a good adjunct to cytology.
