INTRODUCTION: The unexpected diagnosis of breast cancer following total duct excision is distressing for patients. Despite advances in radiology and the description of suspicious nipple discharge, pre-operative diagnosis of malignancy still evades us. The aim of this study was to review the pathological findings of total duct excision and microdochectomy with reference to pre-operative symptoms, ultrasound, or mammographic findings and identify features associated with increased likelihood of malignant disease. METHODS: Data were collected retrospectively of all patients who underwent total duct excision surgery in a single centre (2011-2017). Pre-operative demographics, symptoms, and imaging findings were recorded and correlated with subsequent pathology. RESULTS: 214 patients underwent total duct excision; data were available for 211. Median age was 53 years. 175/211 (82.9%) patients had benign pathology (duct ectasia, papilloma without atypia, fibrocystic change) on final histological examination, 21/211 (10%) had "risk" lesions (papilloma with atypia, atypical ductal hyperplasia), and 15/211 (7.1%) had malignancy (ductal carcinoma in situ). Of the 15 patients with malignant lesions, 6/15 (40%) had normal imaging (M1, U1). 71/211 (33.6%) had normal imaging (M1, U1): 60/71 (84.5%) had benign disease, 5/71 (7%) had "risk" lesions, and 6/71 (8.5%) had malignant lesions. 83/211 (39.3%) patients presented with bloody discharge: 64/83 (77.1%) had benign pathology, 9/83 (10.8%) risk, and 10/83 (12%) malignancy. 38/211 (18%) patients presented with non-bloody discharge: 32/38 (84.2%) had benign disease, 4/38 (10.5%) risk, and 2/38 (5.3%) malignant lesions. CONCLUSION: Neither imaging nor presenting symptoms correlate with the likelihood of malignant disease being present at final pathology. Even with advances in pre-operative diagnosis, total duct excision remains an essential diagnostic and therapeutic procedure.
