Ha HI, et al. - The clinicopathologic features and treatment of uterine smooth muscle tumor of uncertain malignant potential (uSTUMP) were assessed in a single institution, as well as the obstetric outcomes after uterine-preserving surgery for uSTUMP. Via a retrospective chart review of patients diagnosed with uSTUMP between January 2000 and February 2018 at the Comprehensive Gynecologic Cancer Center, CHA Bundang Medical Center, researchers identified a total of 19 patients diagnosed with uSTUMP. A uSTUMP recurrence of 10.5% was observed that is similar to previous reports. Despite the possibility of malignant recurrence, fertility-preserving management appeared worth attempting because of relatively young affected age (mean age at diagnosis was 41 years [range 28–49 years]) with careful close follow-up.
