After completing this course, the reader will be able to:1. Identify changes in medical/surgical practice that can affect the prognostic performance of established prognostic factors such as lymph node involvement in breast cancer.2. Explain how the lymph node ratio can help to adjust against practice-related changes.3. Use the lymph node ratio as a measure of tumor burden in order to weigh the risk of breast cancer death against other causes of death in elderly patients.This article is available for continuing medical education credit at CME.TheOncologist.com.
