title: Locally advanced breast cancer current status and future directions.
abstract: Patients described as having locally advanced breast cancer comprise a heterogeneous group of patients with variable clinical presentations. Systematic evaluation of patients with these presentations has been limited, with much of our current understanding based on retrospective reviews. Prospective pilot studies have demonstrated the feasibility of multimodality therapy. However, there have been few well-conducted randomized trials in this setting. Comparison of results among studies is made difficult by the varying eligibility criteria and the way in which the data are reported. The use of common and consistent definitions of operable and inoperable disease is necessary for a more uniform understanding of the therapeutic interventions necessary for a given patient within this broad category of Stage III or locally advanced breast cancer. There are a variety of opportunities for clinical research activities in this group of patients including tests of hormonal recruitment or synchronization, high dose chemotherapy requiring autologous bone marrow transplantation, perioperative or preoperative chemotherapy, and alternating chemotherapy with short course radiotherapy. The integration of clinical information with biological characteristics of the tumor such as cytokinetics, oncogene amplification, and hormone receptors will be an important and necessary focus of future investigation in this disease.
