Uterine curettage is the only fertility-sparing surgical intervention for LR-NMGTN that has been evaluated in a randomised controlled trial. The evidence is very uncertain about the benefits and harms of uterine curettage, with or without subsequent adjuvant chemotherapy, compared to primary chemotherapy alone. The two available studies are small with a high risk of bias, and future research may find substantially different results for all reported outcomes. Larger RCTs, with appropriate clinical outcome measures, would be required to determine the benefits or harms of fertility-sparing surgical interventions for this population.
