| Definition | |||
|---|---|---|---|
| Low-risk | Intermediate-risk | High-risk | |
| PSA < 10 ng/ml, GS < 7 (ISUP grade 1), cT1-2a | PSA 10–20 ng/ml, GS 7 (ISUP grade 2/3), cT2b | PSA > 20 ng/ml, GS > 7 (ISUP grade 4/5), cT2c | any PSA any GS (any ISUP grade) cT3-4 or cN+ |

| GS– Gleason score; ISUP – International Society for Urological Pathology; PSA – prostate-specific antigen | |||
Table 2
The TNM classification of prostate cancer [19]
| The TNM classification |
|---|
| T - Primary tumor (stage based on DRE only) |
| TX - Primary tumor cannot be assessed T0 - No evidence of primary tumor T1 - Clinically inapparent tumor that is not palpable T1a - Tumor incidental histological finding in 5% or less of tissue resected T1b - Tumor incidental histological finding in more than 5% of tissue resected T1c - Tumor identified by needle biopsy (because of elevated PSA) T2 - Tumor that is palpable and confined within the prostate T2a - Tumor involves one half of one lobe or less T2b - Tumor involves more than half of one lobe, but not both lobes T2c - Tumor involves both lobes T3 - Tumor extends through the prostatic capsule T3a - Extracapsular extension (unilateral or bilateral) T3b - Tumor invades seminal vesicles T4 - Tumor is fixed or invades adjacent structures other than seminal vesicles: external sphincter, rectum, levator muscles and/or pelvic wall |
| N - Regional Lymph Nodes |
| NX - Regional lymph nodes cannot be assessed N0 - No regional lymph node metastasis N1 - Regional lymph node metastasis |
| M - Distant Metastasis |
| M0 - No distant metastasis M1 - Distant metastasis M1a - Non-regional lymph nodes M1b - Bones M1c - Other sites |
| DRE – digital rectal examination; PSA – prostate-specific antigen; TNM – tumor-node-metastasis |
