Risk stratification of localized prostate cancer according to NICE guidance, UK [10]. Gleason score: histological pattern of the tumor. Stage T1–T2a: tumor involving <50% of one lobe. Stage T2b: tumor involving ≥50% of one lobe. Stage T2c: tumor involving both lobes. NICE stands for the National Institute for Health and Care Excellence. PSA stands for Prostate-Specific Antigen.

Level of Risk	PSA Level (ng/mL)		Gleason Score		Clinical Stage
Low risk	<10	and	≤6	and	T1–T2a
Intermediate risk	10–20	or	7	or	T2b
High risk	>20	or	8–10	or	≥T2c
