BLADDER (ICD‐O‐3 C67)


URINARY BLADDER (ICD‐O‐3 C67)


Rules for Classification


The classification applies to carcinomas. Papilloma is excluded. There should be histological or cytological confirmation of the disease.


Anatomical Subsites (Fig. 524)



  1. Trigone (C67.0)
  2. Dome (C67.1)
  3. Lateral wall (C67.2)
  4. Anterior wall (C67.3)
  5. Posterior wall (C67.4)
  6. Bladder neck (C67.5)
  7. Ureteric orifice (C67.6)
  8. Urachus (C67.7)

Regional Lymph Nodes (Fig. 525)


The regional lymph nodes are the nodes of the true pelvis, which essentially are the pelvic nodes below the bifurcation and those along the common iliac arteries. Laterality does not affect the N classification.


TNM Clinical Classification


T – Primary Tumour (Fig. 526)


The suffix (m) should be added to the appropriate T category to indicate multiple tumours. The suffix (is) may be added to any T to indicate presence of associated carcinoma in situ.







































TX Primary tumour cannot be assessed
T0 No evidence of primary tumour
Ta Noninvasive papillary carcinoma
Tis Carcinoma in situ: “flat tumour”
T1 Tumour invades subepithelial connective tissue
T2 Tumour invades muscularis propria

T2aTumour invades muscularis propria (inner half)

T2b Tumour invades deep muscularis propria (outer half)
T3 Tumour invades perivesical tissue:

T3a microscopically

T3b macroscopically (extravesical mass)
T4 Tumour invades any of the following: prostate stroma, seminal vesicles, uterus, vagina, pelvic wall, abdominal wall

T4a Tumour invades prostate stroma, seminal vesicles, uterus, or vagina

T4b Tumour invades pelvic wall or abdominal wall

N – Regional Lymph Nodes


















NX Regional lymph nodes cannot be assessed
N0 No regional lymph node metastasis
N1 Metastasis in a single lymph node in the true pelvis (hypogastric, obturator, external iliac, or presacral) (Fig. 527)
N2 Metastasis in multiple regional lymph nodes in the true pelvis (hypogastric, obturator, external iliac, or presacral) (Fig. 528)
N3 Metastasis in a common iliac lymph node(s) (Fig. 529)
Schematic illustration of Metastasis in a single lymph node in the true pelvis.

M – Distant Metastasis









M0 No distant metastasis
M1aM1b Non‐regional lymph nodesOther distant metastasis

pTNM Pathological Classification


The pT and pN categories correspond to the T and N categories.






pM1a pM1b Non‐regional lymph nodesOther distant metastasis

Note


pM0 and pMX are not valid categories.
