| Cancer Classification |
Corpus Uteri Cancer Classification | |
One of the most frequently used classifications is the classification by the Fédération Internationale de Gynécologie Obstétrique (FIGO) which has allowed comparisons between hospital series for more than 40 years.
The following drawings are available:
This classification requires surgery results and the study of surgical specimens to specify the invasion (when colpo-hysterectomy is feasible).
| TNM |
FIGO |
Description |
| Tx | Primary tumour cannot be assessed | |
| T0 | No evidence of primary tumour | |
| Tis | St 0 | Carcinoma in situ |
| T1 |
St I |
Tumour limited to corpus uteri
|
| T2 |
St II |
Invasion of cervix uteri
|
| T3 and/or N1 |
St III |
Tumour confined to the true pelvis
|
| T4 | St IVa | Tumour invasion of bladder and/or bowel mucosa. |
| M1 |
St IV B | Distant metastases, including intra-abdominal and/or inguinal lymph nodes. |
For non-operated patients, the classification is very similar. However for stage 2 cancers there are two classifications 2a for tumours situated in uteri within a small cavity (as observed on hysterography) and stage 2b for those situated within large uterine cavity.
According to FIGO publications: (Annual report on the results of treatment in gynaecological cancer. Twenty-first volume. Statements of results obtained in patients treated in 1982 to 1986, inclusive 3 and 5-year survival up to 1990. Int J Gynaecol Obstet. 1991 Sep;36 Suppl:1-315)
| Stage | 5 year survival |
| St 1 |
90 - 95 % |
| St 2 |
78 - 85 % |
| St 3 |
50 - 60 % |
| St 4 |
0 - 25 % |
For French speaking readers, the website of the Lorraine oncology network, Oncolor describes the classification of endometrial adenocarcinoma as well as decision trees.
For English speaking readers, the NCI website is most valuable.
Another interesting website for pathology is Webpath from the University of Florida.
