  • Title: Identification of breast cancer in patients with pathologic nipple discharge: does ductoscopy predict malignancy?
    Author: Louie LD, Crowe JP, Dawson AE, Lee KB, Baynes DL, Dowdy T, Kim JA.
    Journal: Am J Surg; 2006 Oct; 192(4):530-3. PubMed ID: 16978968.
    Abstract:
    OBJECTIVE: The purpose of the current study was to review characteristics of patients with nipple discharge who underwent ductoscopy-assisted excisional biopsy who had a final diagnosis of carcinoma. METHODS: A retrospective review was performed of patients presenting with pathologic nipple discharge (PND) who underwent ductoscopy-assisted excisional biopsy and had a final diagnosis of carcinoma. RESULTS: A total of 14 (7%) of 188 patients who underwent ductoscopy-assisted excision had a final pathology of ductal carcinoma-in-situ (DCIS) (12/14, 86%) or invasive breast cancer with DCIS (2/14, 14%). Duct wall irregularities or intraluminal growths were visualized during ductoscopy in 8 of the 14 (57%) breast cancer patients. There were no visual abnormalities noted during ductoscopy that accurately predicted a final diagnosis of malignancy. CONCLUSIONS: Although occult malignancies can be identified in patients undergoing ductoscopy-assisted biopsy for PND, no clear morphologic changes visualized during ductoscopy definitively indicated the presence of malignancy.
