Course description: Toxicity, side effects, and unpredictable effectiveness have been the hallmark of anti-cancer therapies used in the past to treat breast and other primary cancers. Targeted therapies have been developed which reduce patient risk and provide remarkable improvement in patient outcomes. This course will discuss how predictive markers/testing are used to select patients who are most likely to respond positively to a specific breast cancer treatment, including current testing methodologies and compliance standards.
