Sensitivity and specificity of the IHC signatures of MA tumors in ER(-) subgroup.
| IHC biomarker | Sensitivity (95% CI) | Specificity (95% CI) | AUC |
|---|---|---|---|
| AR(+) | 58% (44 to 72) | 100% (75 to 99) | 0.792 (0.726 to 0.859) |
| AR(+) and FOXA1(+) | 57% (43 to 71) | 100% (75 to 99) | 0.787 (0.721 to 0.853) |
| HER2(3+) or GCDFP15(+) | 94% (85 to 99) | 100% (75 to 99) | 0.972 (0.942 to 0.999) |
AR, androgen receptor; ER, estrogen receptor; HER2, Human Epidermal Growth Factor Receptor 2; IHC, immunohistochemistry; MA, molecular apocrine.
