The Whitmore-Jewett staging system (also known as the Jewett staging system or ABCD system) is a superseded staging system for prostate cancer.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 sidewall (T4b)
-
D: metastasis
D1: regional adenopathy (N1 in TNM)
D2: distant metastases (M staging in TNM)
