ERBB2 and breast carcinoma: On [18]F-FDG-PET signaling, Bae Sy et al (2015) et al found that single ER/PG in the HER2-negative breast cancer in 571 subjects was associated with poorer survival than single ER/PG HER2 +ve positive for which result is comparable to the Triple Negative Breast cancer.23 In our study, the SUVmax of [18]F-FDG did not allow any significant differentiation between the 2 HER phenotypes.
