Table 3.
Data of three EM clusters found in pooled data of 1169 breast cancer patients
| Breast cancer patients |
Three EM clusters from the pooled patients’ data | Values for all patients | ||||||
|---|---|---|---|---|---|---|---|---|
| LMA (low mitotic activity) | IMA (intermediate mitotic activity) | HMA (high mitotic activity) | ||||||
| Mean Ki-67% | 13.17 | 40.45 | 77.79 | 25.45 | ||||
| St.dev. of Ki-67 | 8.43 | 13.77 | 8.45 | 21.08 | ||||
| Breast cancer types | n | % | n | % | n | % | Total | % |
| Luminal A/B1 | 560 | 80.92 | 124 | 17.92 | 8 | 1.16 | 692 | 100.00 |
| Luminal B2 | 126 | 63.64 | 68 | 34.34 | 4 | 2.02 | 198 | 100.00 |

These are the results of the second stage of EM clustering that identified the three overall clusters of Ki-67 values (LMA - low mitotic activity; IMA - intermediate mitotic activity; HMA - high mitotic activity). These are the results of the second stage of EM clustering
