Table 3. Comparisons of cancer detection rate on second biopsy between subgroups of HGPIN (1 vs. ≥2) or ASAP (1 vs. ≥2).

	HGPIN		p-value	ASAP		p-value
	1	≥2		1	≥2
No. of patients	90	59		42	11
No. of patients with cancer (%)	15 (16.7)	18 (30.5)	0.047	13 (31.0)	4 (36.4)	0.732

HGPIN, high-grade prostatic intraepithelial neoplasia; ASAP, atypical small acinar proliferation.

HGPIN1, one core of HGPIN; HGPIN≥2, multiple cores of HGPIN; ASAP1, one core of ASAP; ASAP≥2, multiple cores of ASAP.
