Background
Breast carcinoma presented with nipple discharge is a rare condition. There is theoretical concern about preserving nipple in these patients since the risk of nipple–areolar complex involvement may be greater, but not many studies in the literature have addressed on this issue. The aim of the current study was to determine the incidence and outcome of nipple preservation in breast cancer associated with nipple discharge.
Methods
Medical records of patients who were diagnosed to have breast carcinoma and presented with nipple discharge from May 2009 to October 2014 were retrospectively reviewed.
Results
Sixty patients presented with nipple discharge were diagnosed with breast cancer, which represent 3.8 % of all patients who underwent breast cancer surgery in our unit during the study period. Forty-six patients (76.7 %) had nipple discharge as their only symptom, while the rest also presented with breast mass clinically or radiologically. All patients had mammogram and ultrasound performed, and 53.3 and 63.3 % respectively showed suspicious findings. Forty-one out of 46 (89.1 %) nipple discharge cytology were inadequate or benign. Thirty-two microdochectomy were performed. Routine frozen section was utilized intra-operatively to ensure clear margins. The most common histology was ductal carcinoma in situ (DCIS) (n = 29, 48.3 %), followed by DCIS with invasive ductal carcinoma (n = 23, 38.3 %). Regarding treatment, 26 patients (43.3 %) had nipple preserved, including 21 breast conservative surgery and five nipple-sparing mastectomies. Overall, no local or systemic recurrence was observed at a median follow-up of 27 months. Ten out of 34 (29.4 %) mastectomy specimens showed NAC involvement on pathology. By comparing patients with NAC preserved to patients with NAC removed, no significant preoperative predictors were identified.
Conclusion
Breast carcinoma patients who present with nipple discharge usually have early-stage cancer. Presence of nipple discharge is not equivalent to NAC involvement. Nipple preservation can be oncologically safe if negative margins are ascertained.
