De-escalation of axillary surgery in breast cancer patients treated in the neoadjuvant setting: a Dutch population-based study
Purpose: An overall trend is observed towards de-escalation of axillary surgery in patients with breast cancer. The objective of this study was to evaluate this trend in patients treated with neoadjuvant systemic therapy (NST).
