CLIN PATH DEFINITIONS
    PRIMARY TUMOR (T)

TX Primary tumor cannot be assessed

T0 No evidence of primary tumor

T1 Clinically inapparent tumor not palpable or visible by imaging

  T1a Tumor incidental histologic finding in 5% or less of tissue resected

  T1b Tumor incidental histologic finding in more than 5% of tissue resected

  T1c Tumor identified by needle biopsy (e.g. because of elevated PSA)

T2 Palpable tumor confined within prostate*

  T2a Tumor involves half of a lobe or less

  T2b Tumor involves more than half of a lobe, but not both lobes

  T2c Tumor involves both lobes

T3 Tumor extends through the prostatic capsule**

  T3a Unilateral extracapsular extension

  T3b Bilateral extracapsular extension

  T3c Tumor invades seminal vesicle(s)

T4 Tumor is fixed or invades adjacent structures other than seminal vesicles

  T4a Tumor invades external sphincter and/or bladder neck and/or rectum

  T4b Tumor invades levator muscles and/or is fixed to pelvic wall
    LYMPH NODE (N)

NX Regional lymph nodes cannot be assessed

N0 No regional lymph node metastasis

N1 Metastasis in a single lymph node, 2 cm or less in greatest dimension

N2 Metastasis in a single lymph node, more than 2 cm but not more than 5 cm in greatest dimension, or multiple lymph nodes, none more than 5 cm in greatest dimension

N3 Metastasis in a lymph node more than 5 cm in greatest dimension
    DISTANT METASTASIS (M)***

MX Presence of distant metastasis cannot be assessed

M0 No distant metastasis

M1 Distant metastasis

M1a   Non-regional lymph nodes

M1b   Bone

M1c   Other sites

* Note: Tumor found in one or both lobes by needle biopsy, but not palpable or visible by imaging, is classified as T1c.

** Note: Invasion into the prostatic apex or into (but not beyond) the prostatic capsule is not classified as T3, but as T2.

*** Note: When more than one site of metastasis is present, the most advanced category (pM1c) is used.
