QUESTION. What is the value of PET/CT and MRI in predicting subtypes of breast cancer?
METHODS. a retrospective review was done.
RESULTS: high SUV-max was associated with a high Ki-67 index, ER-negative status, and PR-negative status. SUVmax was significantly lower for luminal A than non-luminal A tumors. A cutoff value of 5.4 yielded 79% sensitivity and 68% specificity for prediction that a tumor was the luminal A subtype.
CONCLUSION. FDG PET/CT findings may contribute to differentiation of the luminal A and non-luminal A subtypes of invasive breast cancer.
