OBJECTIVE: To determine the clinical characteristics and treatment outcomes of women with recurrent uterine leiomyosarcoma (uLMS).
METHODS: We conducted a retrospective cohort study to evaluate the clinical characteristics and survival of women with recurrent uLMS and identify prognostic factors.
RESULTS: Overall, 71 patients with first recurrence of uLMS were included in our study. 19 patients (26.8%) received systemic therapy and 52 patients (73.2%) received secondary cytoreductive surgery (SCS). In SCS subgroup (n = 52), a complete resection with no residual disease was performed in 47 patients (90.4%). 38.5% (20/52) patients received non-reproductive organ surgeries. 10 (19.2%) patients had received thoracic surgery because of lung-only recurrence. Bowel, bladder surgery was performed in 8 (15.4%), 3 (5.8%) patients, respectively. 1 (1.9%) patient had received liver surgery. The median follow-up duration was 38.7 months (range: 2.7-317.6 months). 41 (57.7%) patients died during follow-up. 5-year OS for the entire cohort was 52.9%. Patients experienced first recurrence after initial diagnoses within 12 months (n = 24) had a worse 5-year OS than those after 12 months (n = 47) (17.0% vs. 69.1%, P < 0.001). 5-year OS for the SCS and non-SCS subgroup was 62.0% and 28.0%, respectively (P < 0.001). Multivariate analysis showed time to fist recurrence within 12 months (HR = 4.60, 95% CI: 1.49-14.4, P = 0.008) was an independent predictor of decreased 5-year OS in SCS subgroup.
CONCLUSIONS: SCS is an important treatment choice for recurrent uLMS and seems to have benefited patients. Time to fist recurrence within 12 months is an independent predictor of decreased 5-year OS in SCS subgroup.
