Table 3.
The distribution of molecular subtypes among “pure” DCIS and DCIS with an invasive component, according to the IHC surrogate markers, calculated and classified in the manner of 2011 St. Gallen recommendations
Subtypes | Luminal A | Luminal B HER2-negative | Luminal B HER2-positive | HER2-enriched | TPN | |
---|---|---|---|---|---|---|
n = 357 (100%) | n = 110 | n = 70 | n = 79 | n = 78 | n = 20 | |
Percentage of all | 30.8 | 19.6 | 22.1 | 21.8 | 5.6 | 100 |
Percentage of “pure” DCIS | 86 | 90 | 89 | 77 | 90 | 86 |
Percentage of DCIS w/invasion | 14 | 10 | 11 | 23 | 10 | 14 |
