Association between MRI Features and Standardized Uptake Value of 18F-FDG PET/CT in Triple-Negative Breast Cancer
Background:
Triple-negative breast cancer (TNBC) is a breast cancer subgroup that lacks the expression of estrogen receptor (ER), progesterone receptor (PR), and human epidermal growth factor receptor 2 (HER2). Certain magnetic resonance imaging (MRI) features of TNBC might reflect the poor prognosis of TNBC. Standardized uptake value (SUV) of [18F]fluorodeoxyglucose positron emission tomography/computed tomography is 1 of predictive prognostic factors for breast cancer. The purpose of this study was to correlate MRI features of TNBC with SUVmax to determine whether MRI findings in TNBC could be helpful for predicting prognosis.
Methods:
We analyzed MRI findings of TNBC according to breast imaging reporting and data system (BI-RADS) MRI lexicon. We also assessed intratumoral high signal intensity on T2-weighted MRI, time-intensity curve analysis and peritumoral edema. The relationship between MRI features of TNBC and SUVmax was then statistically analyzed.
Results:
Significant correlations of SUVmax with the internal enhancement pattern, intratumoral high signal intensity on T2-weighted images, and peritumoral edema were noted. There was no significant correlation of SUVmax with mass shape, margin, or kinetics.
Conclusion:
Certain MRI features of TNBC such as heterogeneous or rim enhancement, intratumoral very high signal intensity on T2 images, and peritumoral edema might be useful in predicting the prognosis of patients with TNBC.

Distinctive Features of Adult Stem Cells vs Cancer Stem Cells
Adult stem cells
Adult stem cells are tissue-specific; hence, they divide to develop the tissue from which they originate. One type of adult stem cell is the epithelial stem cell, which gives rise to the keratinocytes in the multiple layers of epithelial cells in the epidermis of the skin. Adult bone marrow has three distinct types of stem cells:...
