Gene expression profile (GEP) testing analyzes the expression patterns of a number of different genes within cancer cells to predict the cancer’s aggressiveness and risk of recurrence. GEP testing has been used to help inform decisions on treatments of different cancers. These tests can lead to potential benefits, such as more appropriate treatment decisions and better patient outcomes, including avoidance of treatment-related side effects by forgoing unnecessary treatments.
