| The definitions of the T categories correspond to the stages accepted by the Fédération Internationale de Gynécologie et d'Obstétrique (FIGO). Both systems are included for comparison. | |||
| Primary tumor (T) | |||
| T category | FIGO stage | T criteria | |
| TX | Primary tumor cannot be assessed | ||
| T0 | No evidence of primary tumor | ||
| T1 | I | Tumor confined to the vagina | |
| T1a | I | Tumor confined to the vagina, measuring ≤2.0 cm | |
| T1b | I | Tumor confined to the vagina, measuring >2.0 cm | |
| T2 | II | Tumor invading paravaginal tissues but not to pelvic sidewall | |
| T2a | II | Tumor invading paravaginal tissues but not to pelvic wall, measuring ≤2.0 cm | |
| T2b | II | Tumor invading paravaginal tissues but not to pelvic wall, measuring >2.0 cm | |
| T3 | III | Tumor extending to the pelvic sidewall* and/or causing hydronephrosis or nonfunctioning kidney | |
| T4 | IVA | Tumor invading the mucosa of the bladder or rectum and/or extending beyond the true pelvis (bullous edema is not sufficient evidence to classify a tumor as T4) | |
| * "Pelvic sidewall" is defined as the muscle, fascia, neurovascular structures, or skeletal portions of the bony pelvis. On rectal examination, there is no cancer-free space between the tumor and pelvic sidewall. | |||
| Regional lymph nodes (N) | |||
| N category | FIGO stage | N criteria | |
| NX | Regional lymph nodes cannot be assessed | ||
| N0 | No regional lymph node metastasis | ||
| N0(i+) | Isolated tumor cells in regional lymph node(s) no greater than 0.2 mm | ||
| N1 | III | Pelvic or inguinal lymph node metastasis | |
| Distant metastasis (M) | |||
| M category | FIGO stage | M criteria | |
| M0 | No distant metastasis | ||
| M1 | IVB | Distant metastasis | |
| Prognostic stage groups | |||
| When T is... | And N is... | And M is... | Then the stage group is... |
| T1a | N0 | M0 | IA |
| T1b | N0 | M0 | IB |
| T2a | N0 | M0 | IIA |
| T2b | N0 | M0 | IIB |
| T1-T3 | N1 | M0 | III |
| T3 | N0 | M0 | III |
| T4 | Any N | M0 | IVA |
| Any T | Any N | M1 | IVB |
