TNM 7 Classification
TNM 6 Classification
1. Rules for ClassificationThe classification applies to primary carcinomas only. Tumours present in the vagina as secondary growths from either genital or extragenital sites are excluded. A tumour that has extended to the portio and reached the external os (orifice of uterus) is classified as carcinoma of the cervix. A tumour involving the vulva is classified as carcinoma of the vulva. There should be histological confirmation of the disease.
The following are the procedures for assessing T, N, and M categories:
T categories. Physical examination, endoscopy, and imaging
N categories. Physical examination and imaging
M categories. Physical examination and imaging
The FIGO stages are based on surgical staging. (TNM stages are based on clinical and/or pathological classification.)
The definitions of the T and M categories correspond to the FIGO stages. Both systems are included for comparison.
2. Regional Lymph NodesUpper two-thirds of vagina: the pelvic nodes including obturator, internal iliac (hypogastric), external iliac, and pelvic nodes, NOS.
Lower third of vagina: the inguinal and femoral nodes.
3. TNM Clinical Classification3.1. T - Primary Tumour
3.2. - Regional Lymph Nodes
NX. Regional lymph nodes cannot be assessed
N0. No regional lymph node metastasis
N1. Regional lymph node metastasis
3.3. - Distant Metastasis
MX. Distant metastasis cannot be assessed
M0. No distant metastasis
M1. Distant metastasis
4. pTNM Pathological ClassificationThe pT, pN, and pM categories correspond to the T, N, and M categories.
pN0. Histological examination of an inguinal lymphadenectomy specimen will ordinarily include 6 or more lymph nodes; a pelvic lymphadenectomy specimen will ordinarily include 10 or more lymph nodes. If the lymph nodes are negative, but the number ordinarily examined is not met, classify as pN0.
