Table 4.

Number of positive cores at diagnosis stratified by risk category (among patients with both biopsies and radical prostatectomy performed at our institution).

Risk category	Number of positive cores			P

	≤3 positive cores, n (%)	4–6 positive cores, n (%)	≥7 positive cores, n (%)
Low, n = 6135	4792 (78.1)	1068 (17.4)	275 (4.5)	–
PII, n = 508	406 (79.9)	78 (15.4)	24 (4.7)	0.3414
Intermediate except PII, n = 2725	1406 (51.6)	912 (33.5)	407 (14.9)	<0.001
PIH, n = 71	53 (74.6)	12 (16.9)	6 (8.5)	0.4834
High except PIH, n = 588	251 (42.7)	203 (34.5)	134 (22.8)	<0.001

PII, PSA-incongruent intermediate risk; PIH, PSA-incongruent high risk. P values are for comparisons with low-risk disease.
