Feasibility of uterine preservation in the management of early-stage uterine adenosarcomas: a single institute experience

Abstract

Abstract Background We aimed to evaluate the efficacy and the safety of uterine preservation in patients with early-stage uterine adenosarcoma who want to preserve future fertility. Methods We performed a retrospective review of patients with stage I uterine adenosarcoma diagnosed and treated at a single institute from 1998 through 2014. Results Among the total of 31 patients, uterine preservation surgery was performed in 7 of the nulliparas. Of the 7 patients receiving uterine preservation surgery, 3 showed no evidence of disease (NED), 2 had persistent disease confined to the uterus, and 2 were alive with disease (AWD) after recurrence. One patient with an NED status had a vaginal delivery at term. In the uterine preservation group, 1 patient had sarcomatous overgrowth at the time of diagnosis and experienced disease recurrence. In the hysterectomy group, 3 of 24 patients had tumor recurrence. Of the five patients with tumor recurrence, four (80%) had sarcomatous overgrowth at diagnosis and it was significantly associated with recurrence by univariate analysis (OR 13.3, p = 0.027). Conclusions Uterine preservation represents a possible treatment option for young female patients who want to maintain fertility. However, a detailed explanation of the risk of recurrence is necessary, especially in patients with sarcomatous overgrowth, which seems to be associated with a higher risk of recurrence. Trial registration Retrospectively registered.
