title: Recent advances in the medical treatment of breast cancer.
abstract: Over the past few decades, the systemic therapy of breast cancer (early and advanced) has changed considerably. For the past 40-50 years, and since the discovery and further therapeutic use of tamoxifen, a selective estrogen receptor modulator, breast cancer treatment has become the model for the development and success of tailored medical treatment. Much still needs to be done in improving outcomes for all patients with breast cancer, and especially for those who have advanced breast cancer, a challenging area for medical oncologists. Ongoing international clinical trials are currently evaluating new therapeutic approaches and identifying specific biological subsets that could determine a patient's ability to respond to particular chemotherapeutic drugs.
