Among women with early breast cancer, use of the Oncotype DX® test changed oncologist treatment recommendations in approximately 32% of cases. Use of the test also increased oncologist confidence in the treatment recommendation and decreased patient anxiety. These results were published in the Journal of Clinical Oncology.
The Oncotype DX test measures the expression of 21 genes in a sample of tumor tissue and generates a Recurrence Score. The Recurrence Score predicts the magnitude of chemotherapy benefit and the likelihood of breast cancer recurrence for women with early-stage, estrogen receptor-positive breast cancer.
To explore how use of the Oncotype DX test influences oncologist and patient treatment decisions and satisfaction, researchers collected information from 89 patients treated by 17 medical oncologists. Information about adjuvant treatment plan was collected before and after obtaining the Oncotype DX Recurrence Score.
These results provide additional evidence that Recurrence Score results can influence treatment recommendations and treatment decisions for women with early breast cancer, and can help relieve patient anxiety.
