Abstract
Objective
To examine the association between adjuvant chemotherapy and survival outcomes in patients with stage I uterine leiomyosarcoma (uLMS).
Methods
This comprehensive systematic review and meta-analysis through December 31, 2023 (PROSPERO registration number: CRD42024504776) investigated studies that examined survival outcomes in patients with stage I uLMS using 4 public search engines (PubMed, Scopus, Web of Science, and the Cochrane Central Register of Controlled Trials). Two investigators searched the studies independently, and survival outcomes (overall survival [OS] and disease-free survival [DFS]) were compared between the adjuvant chemotherapy and observation groups. Utilization rate of adjuvant chemotherapy and the regimens used were also assessed. Kaplan-Meier survival curves in the two treatment groups were evaluated using ImageJ software.
Results
From 1988 to 2022, 16 eligible studies including a total of 5690 patients met the inclusion criteria and evaluated the effect of adjuvant chemotherapy on survival outcomes in patients with stage I uLMS. Adjuvant chemotherapy was utilized in 38.5 % of patients (range, 14.8 % to 70.0 %). Eight studies from 2017 to 2022 compared the survival outcomes between adjuvant chemotherapy and observation. OS was comparable between the two groups in both unadjusted (n = 6, hazard ratio [HR] 1.02, 95 % confidence interval [CI] 0.77–1.35, P = 0.88) and adjusted (n = 4, HR 0.90, 95 %CI 0.56–1.43, P = 0.65) pooled analyses. DFS was also similar between adjuvant chemotherapy and observation in both unadjusted (n = 4, HR 0.78, 95 %CI 0.53–1.13, P = 0.18) and adjusted (n = 2, HR 1.14, 95 %CI 0.67–1.94, P = 0.64) pooled analyses. Adjuvant chemotherapy regimens utilized included doxorubicin, ifosfamide, cisplatin, gemcitabine, and docetaxel as monotherapies or combination therapies.
Conclusions
In this contemporaneous systematic review and meta-analysis, less than 40 % of patients received adjuvant chemotherapy for stage I uLMS and adjuvant chemotherapy which was not associated with improved survival. These results support the current National Comprehensive Cancer Network clinical practice guidelines that recommends de-escalating adjuvant chemotherapy in stage I uLMS after complete resection.
