Primary chemotherapy for early breast cancer

The use of primary chemotheraphy represents a novel approach being used with increasing frequency in the management of early breast cancer. Many studies now testify to the usefulness of this modality in increasing the frequency of breast conservation. The acceptance of high-risk breast cancer as a systemic, and therefore predominantly medical rather than a surgical, disease suggests, however, that its role is likely to be far more reaching. While some trials have so far suggested the possibility of a survival benefit for this approach, definitive conclusions are not yet possible and await the final mature results from several large randomized studies. Even if such studies do not show a large extra benefit for primary chemotheraphy over existing adjuvant treatment, the use of the primary tumour as an in vivo model of individual chemosensitivity and the identification of molecular markers as early predictors of response, suggest that this approach will become an integral part of the modern multidisciplinary management of early breast cancer.
