Breast cancer is the most commonly diagnosed cancer and the leading cause of cancer death
in females in the world. Neoadjuvant chemotherapy (NAC) is increasingly used in patients
with operable breast cancer to enhance the likelihood of breast conservation. New
generation of treatments or combinations lead to a high rate of pathological complete
responses (pCR) in patients with human epidermal growth factor receptor 2 positive (HER2)
and triple negative tumours. Safe omission of surgery in patients who receive NAC and
achieve radiologic complete response depends on the ability to accurately estimate pCR
preoperatively.
If pathological complete response after NAC could be accurately assessed by VAB, surgery
could be avoided. In the context of new treatments or combinations with an increased pCR
rate, this new strategy could induce major changes in clinical practice, leading to
breast surgery de-escalation.
