TABLE 241-4. CLINICAL STAGING OF CERVICAL CARCINOMAa |
|
Stage |
Description |
|
0 |
Carcinoma in situ, intraepithelial carcinoma |
|
I |
Carcinoma strictly confined to the cervix (extension to the corpus should be disregarded) |
|
IA |
Preclinical carcinoma (diagnosed only by microscopy)b |
|
IA1 |
Measured invasion of stroma ≤ 3 mm in depth and ≤ 7 mm in width |
|
IA2 |
Measured invasion of stroma > 3 mm and ≤ 5 mm in depth and ≤ 7 mm in width |
|
IB |
Clinical lesions confined to the cervix or preclinical lesions larger than those in stage IA2 |
|
IB1 |
Clinical lesions ≤ 4 cm |
|
IB2 |
Clinical lesions > 4 cm |
|
II |
Carcinoma extending beyond the cervix but not to the pelvic wall; carcinoma involving the vagina but not the lower 1/3 |
|
IIA |
No obvious parametrial involvement |
|
IIB |
Obvious parametrial involvement |
|
III |
Carcinoma extending to the pelvic wall, with rectal examination detecting no cancer-free space between the tumor and the pelvic wall; tumor involving the lower 1/3 of the vagina; includes all cases with hydronephrosis or non-functioning kidney |
|
IIIA |
Extension to the pelvic wall |
|
IIIB |
Extension to the pelvic wall and hydronephrosis, nonfunctioning kidney, or both |
|
IV |
Carcinoma extending beyond the true pelvis or clinically involving the mucosa of the bladder or rectum (bullous edema does not signify stage IV) |
|
IVA |
Spread to adjacent organs |
|
IVB |
Spread to distant organs |
|
aAs described by the International Federation of Gynecology and Obstetrics (FIGO), 1995. |
|
bThe depth of invasion should be measured from the base of the epithelium (surface or glandular) from which it originates.Vascular space involvement (venous or lymphatic) should not alter the staging. |
