The TNM staging system parallels the American Urologic System staging.
| AJCC | Jewett | Definition |
| T0 | No evidence of primary | |
| T1 | A | Clinically inapparent |
| T2 | B | Confined to prostate gland |
| T3 | C | Through the capsule |
| T4 | Fixed; adjacent structures | |
| N_, M_ | D | Distant metastases |
Criteria for TNM Clinical Staging: Physical examination including digital examination, histologic verification of malignancy, imaging, endoscopy, laboratory tests.
Criteria for TNM Pathologic Staging: total removal of the prostate and seminal vesicles as well as pelvic lymph node dissection is required for pathologic staging.
| TNM Classification | Histological/Clinical Features |
| T1 | Not palpable or visible |
T1a |
<=5% |
| T2 | Confined to prostate |
T2a |
One-half of one lobe or less |
| T3 | Through prostatic capsule |
| T3a T3b |
Extracapsular Seminal vesicles(s) |
| T4 | Fixed or invading adjacent structures: bladder neck, external sphincter, rectum, levator muscles, pelvic wall |
| N1 | Regional lymph node(s) |
| M1a | Non-regional lymph nodes(s) |
| M1b | Bone(s) |
| M1c | Other site(s) |
