Table 4A. Comparison of sample classification according to 5 RPPA clusters and 6 gene-expression-based TNBC subtypes for the 52 patients with available data.
| RPPA cluster | BL1 | BL2 | IM | LAR | M | MSL | UNS | p-value |
|---|---|---|---|---|---|---|---|---|
| 1 | 2 | 3 | 2 | 3 | 1 | 3 | 4 | 0.017 |
| 2 | 6 | 0 | 0 | 0 | 1 | 1 | 2 | |
| 3 | 2 | 0 | 1 | 0 | 2 | 0 | 0 | |
| 4 | 0 | 0 | 1 | 0 | 0 | 5 | 1 | |
| 5 | 0 | 0 | 3 | 1 | 3 | 3 | 2 |
P-value shown is the result of Fisher’s exact test for association between the 2 classification results.
Significantly enriched:
BL2 was enriched in RPPA-cluster-1 (p = 0.037)
RPPA cluster 2 was enriched in BL1 (p = 0.002).
RPPA cluster 4 was enriched in MSL (p = 0.005).
