Is mastectomy overtreatment for Pagetʹs disease of the nipple?

The standard local management for Pagetʹs disease of the nipple is currently mastectomy although this may well represent overtreatment. The place of breast conserving surgery is somewhat uncertain. We have reviewed the casenotes of 146 patients with Pagetʹs disease of the nipple, and compared the mortality and recurrence rates between 74 women who had undergone mastectomy and 31 women who had breast conserving surgery. There was no significant difference in either local or overall treatment failure rates between these two treatment groups. We conclude that breast conserving treatment maybe an appropriate alternative to mastectomy for the management of Pagetʹs disease, where clear margins of excision can be achieved. However, a randomized prospective study is needed to confirm this.
