Among women undergoing hysterectomies and varied by age and surgical route, prevalence of occult corpus uteri, cervical, and ovarian malignancy was 1.44%, 0.60%, and 0.19%. The secondary analysis of data from the 2014-2015 American College of Surgeons National Surgical Quality Improvement Program included 24,076 women undergoing hysterectomy and 2,368 women undergoing myomectomy. The primary outcome measure was pathology-confirmed malignancy in the corpus uteri, cervix uteri, and ovary. Researchers found:

• Malignancy of the corpus uteri was found in 1.44% of the women undergoing hysterectomy.
• The prevalence varied considerably across surgical routes with the rate being 0.23% in laparoscopic supracervical hysterectomy and 1.89% in total laparoscopic or laparoscopic-assisted vaginal hysterectomy.
• Older women were significantly more like to have preoperatively undetected malignancy of the corpus uteri.
