title: Adjuvant therapy for patients who have node-positive breast cancer.
abstract: The treatment of node-positive breast cancer has improved dramatically in the last 3 decades. Adjuvant therapies have evolved from single-agent chemotherapy to anthracycline- and taxane-based polychemotherapeutics to target-specific trastuzumab, with or without endocrine manipulation and with or without PMRT. Almost 85% of patients who have node-positive disease can now enjoy a 5-year DFS. This progress has come from incremental improvements made over the years. In spite of these advances, lingering questions remain. Is it possible to reduce treatment-associated toxicity? Can patient selection be improved based on tumor genomic profiling? Given the high cost of many of these therapies (37,000 dollars with the newer agents versus $391 for the classic six cycles of intravenous CMF), is it possible to achieve equivalent efficacy and yet reduce the economic cost per patient? Only continued clinical trials and cooperative effort among researchers, clinicians, and patients can answer these questions and improve care for breast cancer.
