title: The future perspectives of breast cancer therapy.
abstract: Adjuvant therapy after surgery for breast cancer has provided significant benefits to patients at risk of relapse. However, the success of therapy for each individual patient will often take years to reveal. Preoperative therapy has brought about significant advances in the treatment of breast cancer. More breast conservation therapy can be performed and it becomes clear that pathologic complete response (pCR) is a good prognostic marker. Moreover, patients can be segregated into different clinical phenotypes after preoperative therapy: the responder non-recurrent, the responder recurrent, the non-responder non-recurrent and the non-responder recurrent. While conventional therapy and surgery is adequate for the responder non-recurrent and the non-responder non-recurrent cases, modification of conventional therapy, the adoption of a new approach or the incorporation of novel therapeutics may be necessary to improve the pCR and reduce recurrence for the later two groups of patients. Preoperative therapy has also made possible the development of biomarkers to predict response and resistance to treatment. With this translational approach, the therapy for each patient can be more targeted and individualized. A higher rate of success is expected.
