Answer

There is no consensus among oncologists as to appropriate and optimal follow-up for long-term breast cancer survivors. The majority of relapses, both local and distant, occur within the first 3 years, especially in higher-risk and ER-negative patients. The 2007 ASCO guidelines do not support the use of tumor biomarkers, including CEA, CA15.3, and CA27.29, for monitoring patients for recurrence after primary breast cancer therapy. ASCO and NCCN have both provided recommendations for surveillance in the adjuvant setting (see Table 5 below).
