Table 3 5-year biochemical lack of evidence of disease (bNED) in patients treated for prostate cancer with EBRT sorted by 5-level risk stratification, with the hazard ratio of relapse with/without ADT and corresponding p values are generated from the Kaplan-Meier log-rank test.
Risk Group | With ADT | Without ADT | Hazard ratio [95% CI] | P value |
|---|---|---|---|---|
Low | 84% | 86% | 1.8 [0.2–16.6] | n.s |
Low intermediate | 75% | 70% | 1.1 [0.56–2.1] | n.s |
High intermediate | 72% | 55% | 0.57 [0.4–0.83] | P = 0.0029 |
High | 64% | 36% | 0.47 [0.33–0.69] | P = 0.0001 |
Extreme | 43% | 21% | 0.61 [0.42–0.89] | P = 0.01 |
