RCOG | Endometrial hyperplasia

RCOG | Endometrial hyperplasia

This is a new guideline from RCOG on diagnosing and managing endometrial hyperplasia. This is a very common condition, so highly relevant for us and I had no idea on some of the management options. I am therefore doing a general summary.

Types

  • Endometrial Hyperplasia without atypia – fewer than 5% will progress to cancer over 20 yrs and most regress spontaneously.
  • Endometrial Hyperplasia with atypia – there is a much high risk of cancer (8% at 4 yrs, 12% at 9 yrs and 27% at 19 yrs and concomitant cancer is found in 43% of women at hysterectomy).

Risk Factors

Oestrogen exposure, whether exogenous (tamoxifen / oestrogen only HRT) or endogenous (obesity, PCOS or perimenopause with anovulation or estrogen secreting tumours).

Symptoms

  • Heavy menstrual bleeding (beware the over 45s)
  • IMB
  • Irregular bleeding
  • Unscheduled bleeding on HRT
  • Postmenopausal bleeding

 Investigations

  • Endometrial biopsy
  • Hysteroscopic Biopsy (if above undiagnostic or if hyperplasia is found on a polyp)
  • USS transvaginal
