Pathways Clinical Decision Support for Appropriate Use of Key Biomarkers.

Purpose: Breast cancer diagnostics have the ability to predict disease recurrence and the benefit of chemotherapy. This study measures the use of a diagnostic assay, Oncotype DX, when embedded in a breast cancer decision support algorithm and, on the basis of the assay results, the use of chemotherapy in the adjuvant setting.

Methods: UPMC CancerCenter retrospectively reviewed patients with estrogen receptor-positive, human epidermal growth factor receptor 2 (HER2)Neu-negative disease with zero to three positive nodes navigated in the Via Pathways decision support portal during a 12-month period.
