Answer

There are 2 major staging systems that are frequently used in cervical cancer (see Table 2, below and Cervical Cancer Staging):

  • The FIGO system, developed in collaboration with the World Health Organization (WHO) [51]

  • The TNM system, developed by the International Union Against Cancer (UICC) and the American Joint Committee on Cancer (AJCC) [64]

Table 2. Cervical Cancer Staging: Primary Tumor (T) (Open Table in a new window)

TNM Stage

FIGO Stage

 

TX

-

Primary tumor cannot be assessed

T0

-

No evidence of primary tumor

Tis

0

Carcinoma in situ

T1

I

Cervical carcinoma confined to uterus (extension to corpus should be disregarded)

T1a

IA

Invasive carcinoma diagnosed only by microscopy. All macroscopically visible lesions—even with superficial invasion—are T1b/1B. Stromal invasion with a maximal depth of 5.0 mm measured from the base of the epithelium and a horizontal spread of 7.0 mm or less. Vascular space involvement, venous or lymphatic, does not affect classification.

T1a1

IA1

Measured stromal invasion 3 mm or less in depth and 7 mm or less in lateral spread

T1a2

IA2

Measured stromal invasion more than 3 mm but not more than 5 mm with a horizontal spread 7 mm or less

T1b

IB

Clinically visible lesion confined to the cervix or microscopic lesion greater than IA2

T1b1

IB1

Clinically visible lesion 4 cm or less in greatest dimension

 

IB2

Clinically visible lesion more than 4 cm

T2

II

Cervical carcinoma extends beyond the cervix but not to the pelvic sidewall or to the lower third of vagina

T2a

IIA

Tumor without parametrial invasion

T2b

IIB

Tumor with parametrial invasion

T3

III

Tumor extends to the pelvic wall and/or involves the lower third of the vagina and/or causes hydronephrosis or nonfunctioning kidney

T3a

IIIA

Tumor involves lower third of vagina; no extension to pelvic sidewall

T3b

IIIB

Tumor extends to pelvic sidewall and/or causes hydronephrosis or nonfunctioning kidney

-

IV

Cervical carcinoma has extended beyond the true pelvis or has involved (biopsy proven) the bladder mucosa or rectal mucosa. Bullous edema does not qualify as a criteria for stage IV disease.

T4

IVA

Spread to mucosa of adjacent organs (bladder, rectum, or both)

M1

IVB

Distant metastasis
