FIGO staging of cervical cancer (2018).
| Stage | Description |
|---|---|
| I | • The carcinoma is firmly limited to the cervix (extension to the uterine corpus must be ignored) |
| IA | • Invasive carcinoma is only diagnosed by microscopic examination • Maximum depth of invasion lower than 5 mm |
| IA1 | • Measured stromal invasion lower than 3 mm in depth |
| IA2 | • Measured stromal invasion greater than or equal to 3 mm and lower than 5 mm in depth |
| IB | • Invasive carcinoma with measured deepest invasion greater than or equal to 5 mm (greater than Stage IA) • Lesion are limited to the cervix uteri |
| IB1 | • Invasive carcinoma greater than or equal to 5 mm depth of stromal invasion, and lower than 2 cm in greatest dimension |
| IB2 | • Invasive carcinoma greater than or equal to 2 cm and lower than 4 cm in greatest dimension |
| IB3 | • Invasive carcinoma greater than or equal to 4 cm in greatest dimension |
| II | • The carcinoma invades beyond the uterus • The carcinoma has not extended onto the lower third of the vagina or to the pelvic wall |
| IIA | • Tumor limited to the upper two-thirds of the vagina • Parametrial is not involved in this stage |
| IIA1 | • Invasive carcinoma lower than 4 cm in greatest dimension |
| IIA2 | • Invasive carcinoma greater than or equal to 4 cm in greatest dimension |
| IIB | • Parametrial is affected but not up to the pelvic wall |
| III | • The carcinoma involves the lower third of the vagina • Extends to the pelvic wall leading to hydronephrosis or nonfunctioning kidney • Involvement of pelvic and/or para-aortic lymph nodes |
| IIIA | • The carcinoma involves the lower third of the vagina • The pelvic wall is not affected |
| IIIB | • Extension to the pelvic wall • Hydronephrosis or nonfunctioning kidney |
| IIIC | • The pelvic and/or para-aortic lymph nodes are involved • Regardless of tumor size and extent |
| IIIC1 | • Pelvic lymph node metastasis only |
| IIIC2 | • Para-aortic lymph node metastasis |
| IV | • The carcinoma has extended beyond the true pelvis or has involved (biopsy proven) the mucosa of the bladder or rectum * A bullous edema, as such, does not permit a case to be allotted to this stage |
| IVA | • Tumor spreads to adjacent pelvic organs |
