Selective Elimination of Breast Surgery for Invasive Breast Cancer

Cancer research · Breast cancer · ERBB2

Omitting breast surgery after neoadjuvant systemic therapy can be feasible, with a 0% ipsilateral breast tumor recurrence rate observed over a median follow‑up of 55.4 months.

In a single‑arm, prospective phase 2 nonrandomized trial of 50 women with cT1‑2N0‑1M0 ERBB2‑positive or triple‑negative invasive breast cancer who achieved residual breast lesions <2 cm after neoadjuvant systemic therapy, omission of breast surgery and target axillary dissection was accompanied by a 0% ipsilateral breast tumor recurrence rate at a median follow‑up of 55.4 months, with 100% disease‑free and overall survival.

Neoadjuvant systemic therapy achieves pathologic complete response in up to 60% of breast cancers. The finding that breast surgery can be avoided in selected patients challenges a longstanding surgical standard and may reduce morbidity without compromising oncologic outcomes.
