Table 4.
Univariable and multivariable Cox proportional hazards models assessing association of genetic alterations with metastasis.
| Variable | Univariable | Multivariable* | ||
|---|---|---|---|---|
| HR (95% CI) | p-value | HR (95% CI) | p-value | |
| CDKN1B deep deletion | 5.71 (1.23, 26.61) | 0.026 | 6.66 (1.26, 35.22) | 0.026 |
| CHD1 deep deletion† | -- | -- | -- | -- |
| PTEN deep deletion | 4.19 (0.94, 18.62) | 0.060 | 5.16 (0.97, 27.48) | 0.055 |
| FOXA1 mutation | 0.57 (0.08, 4.29) | 0.586 | 0.34 (0.04, 2.76) | 0.310 |
| SPOP mutation | 1.05 (0.30, 3.62) | 0.942 | 1.34 (0.34, 5.32) | 0.678 |
| TP53 mutation | 7.01 (2.01, 24.41) | 0.002 | 9.45 (2.20, 40.55) | 0.002 |
Multivariable models were adjusted for age at RP, PSA, RP grade group <4 or ≥4, and pathologic stage. RP grade group was analyzed as dichotomous variable due to low number of metastatic events per grade group.
No metastatic events were observed for CHD1 genetic alterations, hence HR and p-values were not calculated.
