OBG · Gynaecological oncology: ovarian cancer risk assessment

Sample item

The Risk of Malignancy Index (RMI) for an adnexal mass combines which parameters?

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

The answer and the reasoning

A. Ultrasound score, menopausal status and serum CA-125

RMI equals ultrasound score multiplied by menopausal score multiplied by CA-125 level. A value above 200 suggests a high risk and referral to a gynaecological oncology centre. CA-125 may be raised in endometriosis, menstruation and pelvic infections.

Option by option

  • A. Ultrasound score, menopausal status and serum CA-125 (correct)

    Correct. RMI = U x M x CA-125.

  • B. Ultrasound score, CEA and age

    CEA is not part of the RMI.

  • C. hCG, LDH and AFP

    These are germ cell tumour markers.

  • D. Age, parity and AFP

    Age, parity and AFP are not parameters.
