There was a low risk of occult uterine sarcoma in women undergoing hysterectomy for benign indications, a frequency lower than the rate derived in earlier reports by the US Food and Drug Administration (FDA) in a pooled analysis. This according to a study of patients and 10,119 hysterectomies for benign gynecologic indications over a 14-year period. Researchers found:
• 9 patients were found to have uterine sarcoma (0.089%), with an overall rate of 1 in 1,124.
• The malignancies included 5 leiomyosarcomas, 2 endometrial stromal sarcomas, and 2 uterine adenosarcomas.
• Among women with occult sarcoma, hysterectomy was performed as a primary indication for abnormal bleeding (77.8%) and leiomyomas (22.2%).
• Cases included 6 total abdominal hysterectomies, 2 total vaginal hysterectomies, and 1 supracervical hysterectomy.
• 1 case required manual morcellation during abdominal hysterectomy.
