Serbian consensus of neoadjuvant therapy for breast cancer: NeoPULSE.

Even though surgery is the primary treatment of operable breast cancer, it has been known for decades that the administration of postoperative adjuvant or preoperative neoadjuvant therapy is extremely important. Indications for neodjuvant therapy administration have been expanded over the years, and nowadays this kind of treatment represents an inevitable option in early breast cancer treatment. The NeoPULSE project, which gathered a group of experts in the field of breast cancer from five Serbian university centres, was formed with the aim to define optimal breast cancer diagnosis, indications for neoadjuvant therapy, therapeutic combinations in relation to molecular/ biological parameters of breast cancer, as well as the treatment after neoadjuvant therapy. During two separate expert meetings involving surgeons, medical oncologists, radiation oncologists, a pathologist, and a "Blueprint" workshop, the project participants answered questions over the indications for neoadjuvant therapy. The first part covered local practice and referred to the existence and work of a multidisciplinary team, as well as com-monly applied therapeutic regimens in the neoadjuvant setting. Experts analysed personal views regarding indications for the administration and benefits of neoadjuvant therapy, their perception on the correlation between achieving a pathological complete response (pCR) and the outcome of treatment, as well as the attitude towards controversies about this type of treatment, primarily regarding a possible change in the receptor status after therapy and therapeutic options after a suboptimal response. The analysis of the answers pointed to problems and deviations from recommendations in everyday clinical practice, based on which appropriate solutions were proposed. The establishment of such a panel and consensus is an attempt to modernize multidisciplinary teams in Serbia, achieve reaching uniform decisions of all subjects dealing with breast cancer, and therefore, at least in one segment, improve breast cancer treatment in Serbia.
