Pathologic Staging (pTNM, AJCC 8th Edition)

CAP Approved Gynecologic • Endometrium 4.0.0.0

TNM Descriptors (required only if applicable) (select all that apply)

___ r (recurrent)

___ y (posttreatment)

Primary Tumor (pT)

___ pTX: Primary tumor cannot be assessed

___ pT0: No evidence of primary tumor

___ pT1: Tumor confined to the corpus uteri, including endocervical glandular involvement

___ pT1a: Tumor limited to endometrium or invading less than half of the myometrium

___ pT1b: Tumor invading one-half or more of the myometrium

___ pT2: Tumor invading the stromal connective tissue of the cervix but not extending beyond the uterus. This does NOT include endocervical glandular involvement

___ pT3: Tumor involving serosa, adnexa, vagina, or parametrium

___ pT3a: Tumor involves serosa and/or adnexa (direct extension or metastasis)

___ pT3b: Vaginal involvement (direct extension or metastasis) or parametrial involvement

___ pT4: Tumor invading the bladder mucosa and/or bowel mucosa (bullous edema is not sufficient to classify a tumor as T4)

Regional Lymph Nodes (pN) (select all that apply)

Modifier

___ (sn)#

# Note: Suffix (sn) is required if applicable and added to the N category when only sentinel lymph node biopsy is performed. If after a sentinel node biopsy, the patient then undergoes a complete lymph node dissection, the (sn) suffix is not used.

Category (pN)

___ pNX: Regional lymph nodes cannot be assessed

___ pN0: No regional lymph node metastasis

___ pN0(i+): Isolated tumor cells in regional lymph node(s) no greater than 0.2 mm

___ pN1: Regional lymph node metastasis to pelvic lymph nodes

___ pN1mi: Regional lymph node metastasis (greater than 0.2 mm but not greater than 2 mm in diameter) to pelvic lymph nodes#

___ pN1a: Regional lymph node metastasis (greater than 2 mm in diameter) to pelvic lymph nodes

___ pN2: Regional lymph node metastasis to para-aortic lymph nodes, with or without positive pelvic lymph nodes

___ pN2mi: Regional lymph node metastasis (greater than 0.2 mm but not greater than 2 mm in diameter) to para-aortic lymph nodes, with or without positive pelvic lymph nodes#

___ pN2a: Regional lymph node metastasis (greater than 2 mm in diameter) to para-aortic lymph nodes, with or without positive pelvic lymph nodes

# Note: Even one metastasis >2.0 mm would qualify the classification as pN1a and pN2a.

Distant Metastasis (pM) (required only if confirmed pathologically in this case)

___ pM1: Distant metastasis (includes metastasis to inguinal lymph nodes, intraperitoneal disease, lung, liver, or bone. It excludes metastasis to pelvic or para-aortic lymph nodes, vagina, uterine serosa, or adnexa); Specify site(s), if known:

Endometrial Carcinoma CAP 4.0.0.0 summary of pTNM changes AJCC 7th to 8th edition

1. New pN0(i+) category for isolated tumor cells
2. pN1 and pN2 subdivided into mi and a categories for micro versus macrometastases
3. New (sn) suffix added when only sentinel lymph node biopsy performed
