Endometrial carcinoma (staging)

Endometrial carcinoma staging allows appropriate treatment options to be considered and enables greater prognostic accuracy for endometrial carcinoma. 

Staging

Staging can be based on the TNM or FIGO system. 

MR imaging is the modality of choice for staging with CT having relatively low specificity (especially for myometrial invasion ⁵).

FIGO system

Revised 2009 FIGO staging for carcinoma of the endometrium ⁷:

• stage 0: carcinoma in situ
• stage I: limited to the body of the uterus
  • Ia: no or less than half (≤ 50%) myometrial invasion
  • Ib: invasion equal to or more than half (≥ 50%) of the myometrium
• stage II: cervical stromal involvement
  • endocervical glandular involvement only is stage I
• stage III: local or regional spread of the tumor
  • IIIa: tumor invades the serosa of the body of the uterus and/or adnexa
  • IIIb: vaginal or parametrial involvement
  • IIIc:  pelvic or para-aortic lymphadenopathy
    • IIIc1: positive pelvic nodes
    • IIIc2: positive para-aortic nodes with or without pelvic nodes
• stage IV: involvement of rectum and/or bladder mucosa and/or distant metastasis
  • IVa: bladder or rectal mucosal involvement
  • IVb: distant metastases, malignant ascites, peritoneal involvement
