• Objective: Primary uterine leiomyosarcomas(ULMS) are rare,and the optimal treatment is controversial.We aimed to assess the outcome and prognostic factors in a multicenter population of women treated for primary ULMS.Methods: We retrospectively collected data of 110 women treated in 19 institutions of the Rare Cancer Network(RCN).Inclusion criteria consisted of a pathology report confirming the diagnosis of ULMS,aged 18–80 years,complete International Federation of Gynecology and Obstetrics(FIGO) stage information,complete information on treatment,and a minimum follow-up of 6 months.Local control(LC) and locoregional control(LRC),overall survival(OS) and disease-free survival(DFS) rates were computed using the Kaplan-Meier method.Univariate analysis was implemented using the log rank test,and multivariate analysis using the Cox model.Results: All patients underwent surgery.Seventy-five patients(68%) received adjuvant radiotherapy(RT),including brachytherapy in 18(16%).Seventeen patients(15%) received adjuvant chemotherapy.Median follow-up was 58(range,6–240) months.Five-year OS and DFS rates were 50% and 34%,and LC and LRC rates were 88%and 72%,respectively.On multivariate analysis,independent favorable prognostic factors were younger age,FIGO stage I,small tumor size,previous uterine disease,and no vascular invasion for OS and DFS.FIGO stage was the only favorable factor influencing LRC.Adjuvant local or systemic treatments did not improve the outcomes.Eight patients treated with RT presented a grade 3 acute toxicity,and only one patient with grade 3 late toxicity.Conclusions: In this large population of primary ULMS patients,we found good results in terms of LC and LRC.Nevertheless,OS remains poor,mainly due to the occurrence of distant metastases.An early diagnosis seemed to improve the prognosis of the patients.Adjuvant local or systemic treatments,or more aggressive surgicalprocedures such as the Wertheim procedure,did not seem to impact the outcome.
