New Challenges in Detecting, Grading, and Staging Endometrial Cancer After Uterine Morcellation

Study Objective: To evaluate the accuracy in diagnosing endometrial disease after uterine morcellation. Design: Prospective case series. Setting: University medical center. Patients: Five women undergoing hysterectomy without morcellation because of benign indications and 5 women with endometrial cancer. Interventions: Uterine specimens were obtained from all 10 study patients. The uteri were sent for pathologic analysis, processed, and fixed according to standard protocols. A single investigator then morcellated all 10 uteri. A single pathologist blinded to specimen group reviewed each specimen. Main Results: The pathologist identified endometrial cancer in 4 of 5 specimens of known cancer. The fifth specimen was interpreted as benign despite the presence of grade 1, stage IA endometrial adenocarcinoma. None of the morcellated specimens could be staged. Conclusion: The increasing use of uterine morcellation will result in new challenges for gynecologic oncologists secondary to difficulty in detection, and accurate grading and staging of endometrial cancer.
