ABCD Staging System (Prostata)

Whitmore-Jewett staging system (also known as the Jewett staging system or ABCD system) is a staging system for prostate cancer. It was developed by the American Urological Association (AUA). Most societies (including AUA) and clinicians now advocate and use the TNM staging system.

• A: subclinical tumor: found incidentally (T1 in TNM)
  • A1: tissue resembles normal cells; found in a few chips from one lobe
  • A2: more extensive involvement
• B: tumor palpable on digital rectal exam (DRE): no extraprostatic extension (T2 in TNM)
  • B1: less than 50% one lobe
  • B2: more than 50% one lobe
  • B3: both lobes
• C: extracapsular extension (T3/T4 in TNM)
  • C1: unilateral, not seminal vesicles (T3a)
  • C2
    • ​bilateral, not seminal vesicles (T3b)
    • seminal vesicles (T3c)
    • bladder neck, external anal sphincter, and/or rectum (T4a)
    • levator muscles, and/or fixed to pelvic side wall (T4b)
• D: metastasis
  • D1: regional adenopathy (N1 in TNM)
  • D2: distant metastases (M staging in TNM)
