Patients' preferences for surgical and adjuvant systemic treatment in early breast cancer: a systematic review.

Treatment decisions in early breast cancer can revolve around type of surgery and whether or not to have adjuvant systemic therapy. This systematic review aims to give an overview of patient self-reported factors affecting preferences for breast conserving surgery (BCS) versus mastectomy (MAST), the minimal benefit patients require from adjuvant chemotherapy (aCT) and/or adjuvant hormonal therapy (aHT) to consider it worthwhile, and factors influencing this minimally-required benefit.
