Cytyc Announces New UK NICE Clinical Guideline Recommends Endometrial Ablation Instead of Hysterectomy For Most Women with Heavy Menstrual Bleeding

Jan. 30, 2007 -- Cytyc Corporation, a leading provider of surgical and diagnostic products targeting cancer diagnostics and women's health, today announced that a new clinical guideline for Heavy Menstrual Bleeding (HMB), published this month by the UK National Institute for Health and Clinical Excellence (NICE), recommends endometrial ablation as preferable to hysterectomy for the treatment of most women who suffer from heavy menstrual bleeding alone. The new guideline was developed by the National Collaborating Centre for Women's And Children's Health, which is based in the Royal College of Obstetricians and Gynecologists.

The document provides recommendations on diagnosis and a care pathway for HMB, as well as information on a variety of treatment options. The new Clinical Guideline provides a review of various endometrial resection and second-generation endometrial ablation techniques such as Cytyc's NovaSure(R) Endometrial Ablation System, described as "bipolar radiofrequency endometrial ablation." The report highlights a study showing that the NovaSure System demonstrated higher amenorrhea rates and greater overall patient satisfaction with treatment outcome at 12 months compared to thermal balloon endometrial ablation (TBEA).

"This is an important clinical milestone for the NovaSure System in the UK and we commend the NICE for acknowledging the benefits of second generation endometrial ablation techniques, such as the NovaSure System, and the importance of patient choice," said Ellen Sheets, M.D., Cytyc's chief medical officer.

Additional recommendations contained in the Guideline include:

  • Endometrial ablation should be considered where bleeding is having a severe impact on a woman's quality of life, and she does not want to conceive in the future.
  • Endometrial ablation may be offered as an initial treatment for HMB after full discussion with the woman of the risks and benefits and of other treatment options.
  • All women considering endometrial ablation should have access to a second-generation ablation technique.
