Pathologic T

This input is used for staging

Notes

**Note 1:** Assign 88 for in situ cases (behavior code /2). TNM does not include an in situ category for prostate tumors. **Note 2:** T1 (T1a, T1b, T1c and T1 [NOS]) are only used for clinical evaluation of prostate tumors. **Note 3:** When prostate cancer is an incidental finding during a prostatectomy for other reasons (for example, a cystoprostatectomy for bladder cancer), assign the appropriate T category for the extent of disease found (for example, involvement in one lobe, both lobes, or more) **Note 4:** When the apical margin, distal urethral margin, bladder base margin, or bladder neck margin is involved and there is no extracapsular extension, assign pT2. **Note 5:** Invasion into the prostatic apex or into (but not beyond) the prostatic capsule is not classified as T3, but as T2

Pathologic T Pathologic T Display Description Registrar Notes
pX pTX Primary tumor cannot be assessed Pathologic classification criteria met, evaluation done:
Physician unable to assess T
Surgical resection of primary tumor, extension not stated
Physician assigns pTX, no other information available to determine T
p0 pT0 No evidence of primary tumor
p2 pT2 Tumor confined within prostate Note: T2 has subcategories of T2a, T2b and T2c. Assign T2 only when there is no information available to assign one of the subcategories

Invasion into (but not beyond) prostatic capsule
Involved one lobe/side, NOS

Intracapsular involvement only
No extracapsular extension but specific margins involved (see Note 4)

Confined to prostate, NOS
Localized, NOS

Stated as T2 [NOS]
p2A pT2a Tumor involves one-half of one lobe or less Involves one half of one lobe/side or less

No extracapsular extension but specific margins involved plus involves one half of one lobe/side or less

Stated as T2a
p2B pT2b Tumor involves more than one-half of one lobe, but not both lobes Involves more than one half of one lobe/side, but not both lobes/sides

Invasion into (but not beyond) prostatic capsule plus involves more than one half of one side/lobe, but not both lobes/sides

No extracapsular extension but specific margins involved plus involves more than one half of one lobe/side, but not both lobes/sides
(see Note 4)

Stated as T2b
p2C pT2c Tumor involves both lobes Involves both lobes/side

Invasion into (but not beyond) prostatic capsule plus involves both lobes/sides

No extracapsular extension but specific margins involves plus involves both lobes/sides
(see Note 4)

Stated as T2c
p3 pT3 Tumor extends through the prostatic capsule Note: T3 has subcategories of T3a and T3b. Assign T3 only when there is no information available to assign one of the subcategories

Stated as T3 [NOS]
p3A pT3a Extracapsular extension (unilateral or bilateral)
Including microscopic bladder neck involvement
Extracapsular extension (beyond prostatic capsule), NOS
Through capsule, NOS
Extracapsular extension and specific margins involved (see Note 4)
Extension to periprostatic tissue

Stated as T3a
p3B pT3b Tumor invades seminal vesicle(s) Extension to seminal vesicle(s) plus microscopic bladder neck involvement

Stated as T3b
p4 pT4 Tumor is fixed or invades adjacent structures other than seminal vesicles:
External sphincter
Rectum
Levator muscles
Pelvic wall
Extension to or fixation to adjacent structures other than seminal vesicles:
Bladder neck, except microscopic bladder neck involvement
Bladder, NOS
Fixation, NOS
Rectovesical (Denonvillier's) fascia

Extraprostatic urethra (membranous urethra)

Skeletal muscle, NOS
Ureter(s)

Extension to or fixation to pelvic wall or pelvic bone

Further contiguous extension including:
Bone
Other organs
Penis
Sigmoid colon
Soft tissue other than periprostatic

Stated as T4
88 88 Not applicable Primary site/histology not TNM defined
In situ case but no pTis is defined by TNM
Death certificate only (DCO) case
<BLANK> BLANK See Registrar Notes Pathologic classification criteria not met
Pathologic classification criteria met, evaluation done:
Results not documented in patient record
No surgical resection of known primary tumor (not T0)
Resection insufficient for site-specific pathologic assessment
No surgical resection of primary tumor and there isn’t a positive biopsy of a structure in the highest T category and highest N category
Evidence of metastatic disease (pM1), no other workup
Only Pathologic Stage Group documented (no T, N, or M information available)
