PURPOSE: The aim of this study was to determine the upgrade rate of image-guided core needle biopsy (CNB)-proven benign breast intraductal papillomas (IDPs) without atypia to high-risk benign lesions or malignancy after surgical excision.
METHODS: A retrospective database search at a single institution identified 102 adult female patients with benign breast IDPs without atypia diagnosed on imaging-guided CNBs who subsequently had surgical excisions between 2011 and 2016. Patient characteristics, imaging features, biopsy techniques, and the pathology reports from imaging-guided CNBs and subsequent surgical excisions were reviewed. The upgrade rate to malignancies or high-risk benign lesions was determined at the patient level.
RESULTS: The upgrade rate to malignancy was 2.9% (3/102), including two cases of ductal carcinoma in situ (DCIS) and one case of microinvasive (< 1 mm) ductal carcinoma arising from DCIS. The upgrade rate to high-risk benign lesions was 7.8% (8/102), with seven cases of atypical ductal hyperplasia and one case of atypical lobular hyperplasia. A personal history of breast cancer and a larger mean lesion size were significantly associated with an upgrade to malignancy (p < 0.05).
CONCLUSIONS: The management of benign breast IDPs without atypia detected on imaging-guided CNBs is controversial. Our results suggest risk stratification is important in approaching these patients. Although surgical excision should be considered for all benign breast IDPs without atypia, observation with serial imaging may be appropriate in selected low-risk patients. This approach will save many women from surgeries and decrease the cost of medical care.
