| TNBC relevancya | Intrinsic subtypesb | Receptor statusb |
|---|---|---|

| Does not include TNBC diagnoses | Luminal A | ER+ |
| Luminal B | PR+ | |
| HER2-enriched | ER+ and PR+ ER+ and PR+ and HER2− ER+ and PR+ and HER2+ HER2+ |

| TNBC diagnoses | Basald | ER−PR−HER2− |
Abbreviations: ER – Estrogen Receptor, PR – Progesterone Receptor, TNBC – Triple Negative Breast Cancer, HER2 – Human Epidermal growth factor Receptor 2.
a
Breast cancer diagnoses grouping according to relevancy of TNBC.
b
Ways in which breast cancer diagnoses were categorized in results included in this review.
c
Diagnoses which did not report all three receptor statuses (ER, PR, HER2) prevent definitive determination of TNBC status.
d
Cancers identified as basal are assumed to be TNBC.
