Similarly, after adjustment for other baseline patient characteristics (BMI and prostate volume), preoperative PSA value, pathologic tumor characteristics, and adjuvant radiation therapy in multivariable Cox regression models, patient age did not achieve independent predictor status for BCR rate after radical prostatectomy, either as a continuously coded variable (p = 0.5) or after stratification based on quartiles (p = 0.1 and p = 0.6). This evidence concerns the gene KLK3 and neoplasm.
