Text: Multivariate Cox regression model analyses of the pretreatment PSA level (> 20 ng/ml n = 16 vs. < or = 20 ng/ml n = 23), grade (G8 or more n = 11 vs. G7 or less n = 28) and modality (LHRH group n = 19 vs. EMP group n = 20) revealed these factors to be independent predictors of PSA relapse after treatment : pretreatment PSA had a relative risk of 3. 84 (95 % CI : 1. 003-14. 722), grade had a relative risk of 4. 29 (95 % CI : 1. 093-16. 824), and modality had a relative risk of 8. 01 (95 % CI : 1. 867-34. 361).
