Tumours can have high levels of heterogeneity. Lesions demonstrating high levels of heterogeneity have an ‘aggressive’ phenotype. Assessing heterogeneity might provide superior insights into treatment response than traditional mean/median values. The aims of this study were to determine if histogram analysis of pre-treatment DCE-MRI parameters are associated with traditional prognostic indicators and early breast cancer recurrence.
Breast dynamic datasets from 208 individuals underwent histogram analysis. U-tests and survival analysis indicated that DCE-MRI histogram parameters are associated with traditional prognostic indicators, have superior prognostic information than mean/median values and provide independent prognostic information regarding breast cancer recurrence prior to therapy initiation.
