Vulva(Pathological) - TNM Calc

This view displays the TNM formula. Please select appropriate value from the list for T/N/M/G variables. The result will be displayed, based on your selection of variables.

Pathological T (pT)

pT Category FIGO Stage pT Criteria
pTX N/A Primary tumor cannot be assessed
pT0 N/A No evidence of primary tumor
pT1 I Tumor confined to the vulva and /or perineum. Multifocal lesions should be designated as such. The largest lesion or the lesion with the greatest depth of invasion will be the target lesion identified to address the highest pT stage. Depth of invasion is defined as the measurement of the tumor from the epithelial-stromal junction of the adjacent most superficial dermal papilla to the deepest point of invasion.
pT1a IA Lesions 2 cm or less, confined to the vulva and /or perineum, and with stromal invasion of 1.0 mm or less
pT1b IB Lesions more than 2 cm, or any size with stromal invasion of more than 1.0 mm, confined to the vulva and /or perineum
pT2 II Tumor of any size with extension to adjacent perineal structures (lower/distal third of the urethra, lower/distal third of the vagina, anal involvement)
pT3 IVA Tumor of any size with extension to any of the following—upper/proximal two thirds of the urethra, upper/proximal two thirds of the vagina, bladder mucosa, or rectal mucosa—or fixed to pelvic bone
cTX N/A Primary tumor cannot be assessed
cT0 N/A No evidence of primary tumor
cT1 I Tumor confined to the vulva and /or perineum. Multifocal lesions should be designated as such. The largest lesion or the lesion with the greatest depth of invasion will be the target lesion identified to address the highest pT stage. Depth of invasion is defined as the measurement of the tumor from the epithelial-stromal junction of the adjacent most superficial dermal papilla to the deepest point of invasion.
cT1a IA Lesions 2 cm or less, confined to the vulva and /or perineum, and with stromal invasion of 1.0 mm or less
cT1b IB Lesions more than 2 cm, or any size with stromal invasion of more than 1.0 mm, confined to the vulva and /or perineum
cT2 II Tumor of any size with extension to adjacent perineal structures (lower/distal third of the urethra, lower/distal third of the vagina, anal involvement)
cT3 IVA Tumor of any size with extension to any of the following—upper/proximal two thirds of the urethra, upper/proximal two thirds of the vagina, bladder mucosa, or rectal mucosa—or fixed to pelvic bone
Pathological N (pN)
pN Category FIGO Stage pN Criteria
pNX N/A Regional lymph nodes cannot be assessed
pN0 N/A No regional lymph node metastasis
pN0(i+) N/A Isolated tumor cells in regional lymph node(s) no greater than 0.2 mm
pN1 III Regional lymph node metastasis with one or two lymph node metastases each less than 5 mm, or one lymph node metastasis greater than or equal to 5 mm
pN1a IIIA One or two lymph node metastases each less than 5 mm
pN1b IIIA One lymph node metastasis greater than or equal to 5 mm
pN2 N/A Regional lymph node metastasis with three or more lymph node metastases each less than 5 mm, or two or more lymph node metastases greater than or equal to 5 mm, or lymph node(s) with extranodal extension
pN2a IIIB Three or more lymph node metastases each less than 5 mm
pN2b IIIB Two or more lymph node metastases greater than or equal to 5 mm
pN2c IIIC Lymph node(s) with extranodal extension
pN3 IVA Fixed or ulcerated regional lymph node metastasis
cNX N/A Regional lymph nodes cannot be assessed
cN0 N/A No regional lymph node metastasis
cN0(i+) N/A Isolated tumor cells in regional lymph node(s) no greater than 0.2 mm
cN1 III Regional lymph node metastasis with one or two lymph node metastases each less than 5 mm, or one lymph node metastasis greater than or equal to 5 mm
cN1a IIIA One or two lymph node metastases each less than 5 mm
cN1b IIIA One lymph node metastasis greater than or equal to 5 mm
cN2 N/A Regional lymph node metastasis with three or more lymph node metastases each less than 5 mm, or two or more lymph node metastases greater than or equal to 5 mm, or lymph node(s) with extranodal extension
cN2a IIIB Three or more lymph node metastases each less than 5 mm
cN2b IIIB Two or more lymph node metastases greater than or equal to 5 mm
cN2c IIIC Lymph node(s) with extranodal extension
cN3 IVA Fixed or ulcerated regional lymph node metastasis

Includes micrometastasis, N1mi and N2mi.

The site, size, and laterality of lymph node metastasis should be recorded.

Definition of Distant Metastasis (M)- Pathological M (pN)

pM Category FIGO Stage PM Criteria
cM0 N/A No distant metastasis (no pathological M0; use clinical M to complete stage group)
cM1 IVB Distant metastasis (including pelvic lymph node metastasis)
pM1 IVB Microscopic evidence of distant metastasis (including pelvic lymph node metastasis)
