Table 2 Multivariate analysis of risk factors associated with biochemical recurrence from prostate cancer after radical prostatectomy in patients with node-positive disease

From: Outcomes of patients with lymph node metastasis treated with radical prostatectomy and adjuvant androgen deprivation therapy in a Chinese population: results from a cohort study

Risk factor HR (95% CI) P value (chi-square test)
Preoperative PSA (>=20 ng/ml or not) 0.6(0.3 to 1.4) 0.246
Pathologic Gleason grade (>7 vs. ≤=7) 1.1(0.6 to 2.1) 0.795
Tumor stage (pT3/4 vs. pT2) 1.4(0.6 to 3.0) 0.435
Positive surgical margin 0.9(0.5 to 1.9) 0.853
Positive nodes removed (2 or more vs. 1) 2.6(1.3 to 5.1) 0.005
