Whitmore-Jewett staging system

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)
