Multivariate analyses of overall and cancer-specific survival in related to metastatic sites.
| Variable | Overall survival | Cancer-specific survival | ||
|---|---|---|---|---|
| HR (95% CI) | P | HR (95% CI) | P | |

| Bone metastasis | 1.312 (1.302–1.321) | <0.001 | 1.337 (1.328–1.348) | <0.001 |
| Brain metastasis | 1.339 (1.328–1.351) | <0.001 | 1.368 (1.357–1.381) | <0.001 |
| Liver metastasis | 1.344 (1.333–1.355) | <0.001 | 1.375 (1.363–1.388) | <0.001 |
