Extreme oncoplastic conservation is a safe new alternative to mastectomy.

Objectives: Extreme oncoplastic breast conserving surgery (eOPBCS) allows breast conservation for tumours ≥ 50 mm, but long-term outcomes are unclear. We investigated early complications and the longer-term clinical and oncological outcomes following eOPBCS to assess the clinical utility and safety of this technique.

Materials And Methods: A prospectively collected database of all eOPBCS procedures (1993-2016) using LD miniflaps (LDm) and therapeutic mammoplasties (TM) was interrogated and cross-checked with hospital records to establish length of follow up (FU), clinical outcomes (complications, revisions), local recurrence (LR) and survival.
