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 T2NAACCR Item
NAACCR #880Pathologic 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) |
