As evidence questioning the rationale behind neoadjuvant chemotherapy in breast cancer grows, Jayant Vaidya and colleagues say we must reconsider the current treatment options

Key messages

  • Neoadjuvant chemotherapy is being increasingly used for breast cancer despite higher rates of local recurrence and no evidence of survival benefit, mainly because of the immediate and dramatic pathological responses seen with newer drugs

  • The increased pathological response of the primary tumour does not translate into a survival benefit even when given in the adjuvant setting, challenging the paradigm of “window of opportunity” studies

  • We must acknowledge that neoadjuvant chemotherapy may not be beneficial to patients

  • We should consider reducing the widespread use of neoadjuvant chemotherapy

Breast cancer is the most common cancer in women worldwide. In 2014, 55 000 women in the UK were given the diagnosis of breast cancer, and 11 000 died.1 Early breast cancer is traditionally treated with surgery, plus radiotherapy and adjuvant systemic therapy as required.

Neoadjuvant chemotherapy for breast cancer is a new strategy that was introduced towards the end of the 20th century with the aim of reducing tumour size. It has four main rationales. Firstly, it should render an otherwise inoperable tumour operable or, secondly, allow more conservative surgery. Thirdly, starting systemic treatment preoperatively was hoped to lead to improved overall survival in patients with locally advanced cancers, who are at high risk of having distant disease. Finally, unlike adjuvant chemotherapy given in the absence of any measurable disease, neoadjuvant chemotherapy gives us the opportunity to observe the tumour shrink both palpably and on imaging, enabling a rapid assessment of clinical response. This could help test responses in vivo to new drug regimens, which could then be used as adjuvant therapies, in so called window of opportunity studies.
