Emerging studies suggest that imaging features could complement standard pathologic variables in cancer prognostic assessment. Studies on the association of background parenchymal enhancement (BPE) with breast cancer prognosis remain limited. The goal of this study was to investigate the complementary value of breast BPE as a prognostic marker for breast cancer recurrence risk assessment. DCE-MRI images were retrospectively analyzed from 100 women with breast cancer. Oncotype DX score was used as a surrogate for cancer recurrence. Our results suggest that BPE could complement histopathologic factors in predicting breast cancer recurrence risk and could potentially improve breast cancer prognostication.
