OBG · Gynaecological oncology: myometrial invasion in endometrial cancer

Sample item

A woman has an endometrioid endometrial carcinoma that invades less than half of the myometrium and has no cervical or adnexal involvement. What is its FIGO 2009 stage?

Original practice item, not a recalled exam question. Nothing here is recorded.

The answer and the reasoning

B. Stage IA

In FIGO staging, stage IA is confined to the uterus with no or less than 50 percent myometrial invasion, and stage IB has invasion of 50 percent or more. Stage II involves the cervical stroma, and stage III involves serosa, adnexa, vagina or nodes. Pelvic MRI helps evaluate depth of invasion preoperatively.

Option by option

  • A. Stage IB

    Stage IB requires invasion of half or more of the myometrium.

  • B. Stage IA (correct)

  • C. Stage II

    Stage II needs cervical stromal invasion.

  • D. Stage IIIA

    Stage IIIA needs serosal or adnexal involvement.
