Evaluating PSA Density as a Predictor of Biochemical Failure after Radical Prostatectomy: Results of a Prospective Study after a Median Follow-Up of 36 Months

Table 3

Correlation of PSA density to adverse pathological findings and biochemical recurrence.

	PSM	ECD	SVI	LNI	BCR
Mean ± std	0.32 ± 0.47	0.28 ± 0.45	0.09 ± 0.29	0.40 ± 0.45	0.29 ± 0.46
P (2-tailed)	0.239	<0.001*	0.009*	0.080	0.040*

Statistics were made by using Pearson’s correlation (significance <0.05), *statistically significant, std: standard deviation, PSM: positive surgical margins, ECD: extracapsular disease, SVI: seminal vesicles invasion, LNI: lymph nodes invasion, and BCR: biochemical recurrence.
