RESUMEN
Neoadjuvant therapy is a cornerstone of some early and locally advanced breast cancer treatment. The use of neoadjuvant chemotherapy, in fact, allows to obtain numerous advantages, including allowing a more conservative intervention, evaluating the in vivo response to therapy, modulating the intensity of subsequent treatments based on the degree of response to therapy and allowing to surgery with information on genetics. However, at the end of neoadjuvant cytotoxic therapy it is not possible to carry out surgery immediately, as a certain amount of time is required for recovery from toxicity, especially haematological, due to the systemic therapy itself. At the same time, it is intuitive that too much time must not pass between the end of neoadjuvant therapy and surgery. The goal of this systematic literature review is to summarize the most relevant literature data on this topic, selected and extracted according to the methodology of systematic reviews.
