Quantitative magnetic resonance imaging measures were associated with prognostic tumor markers, demonstrating the potential of magnetic resonance imaging for prediction of disease prognosis and stratification of patients to appropriate therapies, according to preliminary data presented at the 2011 CTRC-AACR San Antonio Breast Cancer Symposium, held Dec. 6-10, 2011.
"Breast cancers are heterogeneous, and different subtypes of breast cancer will respond differently to therapy," said Sana Parsian, M.D., a research assistant in the department of radiology at the University of Washington in Seattle. "Every patient with breast cancer must undergo biopsy to be evaluated for the type of breast cancer they have. Based on that, adjuvant medical therapies are prescribed for them."
Parsian and her colleagues hypothesized that some quantitative magnetic resonance imaging (MRI) measures, such as diffusion-weighted MRI (DWI) and dynamic contrast-enhanced MRI (DCE), would correlate with histopathological markers by enabling the researchers to measure the tumor's cellularity and vascularity.
