Abstract

Purpose

To evaluate the clinical benefits of hormonal treatment for patients with low-grade endometrial stromal sarcoma (LG-ESS) by reviewing the published literature and performing a meta-analysis.

Methods

Correlational studies related to hormonal treatment for LG-ESS patients were collected by searching the PubMed, EMBASE, and Cochrane databases up to December 2018. Eligible studies were selected based on inclusion and exclusion criteria. The main inclusion criteria included: original studies with definite diagnoses of LG-ESS that evaluated the clinical benefits of hormonal treatment, studies with at least 10 cases, and studies published in English. Reviews, case reports, letters, comments or conference abstracts, studies without sufficient data and overlapping or republished studies were excluded. The study quality was evaluated, and pooled relative risks and 95% confidence intervals were calculated using Review Manager 5.3.

Results

A total of 10 retrospective studies were included. The NOS stars of the 10 studies ranged from 7 to 9 points, which was considered to be of high quality. Recurrence and death information was provided in 9 and 6 studies, respectively. The overall pooled RR for recurrence was 0.66 (95% CI 0.47–0.94), which indicated that hormonal treatment was effective at reducing the recurrence risk (P = 0.02). The overall pooled RR for death was 0.81 (95% CI 0.59–1.12), which showed that hormonal treatment had little effect in prolonging overall survival (P = 0.20). Stratified analysis showed that compared with the group without any adjuvant treatments, hormonal treatment alone significantly decreased the risk of recurrence (P = 0.02), while hormonal treatment had no significant effects on overall survival (P = 0.38). Another subgroup analysis indicated that for stage I–II patients, hormonal treatment could significantly decrease the risk of recurrence (P = 0.02) but could not influence overall survival (P = 0.87). However, for stage III–IV patients, hormonal treatment had little benefit both in reducing the recurrence risk and prolonging overall survival (P = 0.49/0.08). Egger’s and Begg’s test showed that the publication bias for the literature was satisfactorily controlled.

Conclusion

Adjuvant hormonal treatment should be considered as a feasible adjuvant therapy for reducing the recurrence risk of patients with LG-ESS while bearing little benefit on overall survival.
