Abstract
INTRODUCTION: The management of complex cysts of the breast is an ongoing topic of discussion. The aim of this study was to determine the prevalence of underlying malignancy in radiologically diagnosed complex cysts, and to assess whether watchful waiting could be the preferred method to safely manage complex cysts of the breast. SUBJECTS AND METHODS: A single-center retrospective study was performed between May 2003 and November 2019 in the VieCuri Medical Centre. Women with a radiologically diagnosed complex cyst of the breast were included. Prevalence of underlying malignancy was calculated, as were absolute risk reduction and number needed to treat in order to diagnose malignancy. In addition, patient characteristics were compared to determine characteristics associated with malignancy. RESULTS: Of 78 radiologically diagnosed complex cysts of the breast, five (6,4%) were found to be malignant. The number needed to treat was calculated at 12,8 (absolute riks reduction 0,078). Age (P = 0,003) was associated with malignancy. CONCLUSION: Complex cysts of the breast could be managed more conservatively. Patient characteristics can be used to assess the eligibility for radiological follow-up. This, in turn, would lead to a lower NNT and possibly a decrease in disease burden and healthcare costs.
