Background Uterine leiomyosarcomas (LMS) are associated with more recurrence and higher mortality compared to other uterine cancers. Considering the limited number of case series in the literature, the limited effectiveness of standard treatment methods, and the inadequacy of molecular biomarkers, we planned to investigate the effects of treatment methods and survival outcomes in these patients.Methodology The study was designed retrospectively, and the records of patients who were followed up and treated at Ankara University Faculty of Medicine, Medical Oncology Clinic, between January 1, 2011, and December 31, 2021, were reviewed. Patients over 18 years of age with a pathological diagnosis of uterine LMS were included. Demographic, clinical, and pathological data were recorded using the hospital database. The International Federation of Gynecology and Obstetrics (FIGO) staging was reassessed for each patient in accordance with the AJCC Cancer Staging Manual, Eighth Edition (2017). Tumor size, location, and grade were also evaluated. Types of treatments, protocols, and adverse effects were recorded. Relapsed patients, relapse localization, and treatments given at relapse were recorded and compared.Results Twenty-eight patients were included. The mean age of the patients was 53.7 years. The median follow-up time was 39.3 months. The localization of LMS could be detected in 22 (78.57%) patients, among them 20 (90.9%) patients had intramural, 1 (4.5%) had submucosal, and 1 (4.5%) had subserosal LMS. All patients (26, 92.8%) underwent primary surgery, except for 2 (7.14%) patients who were metastatic at the time of diagnosis. Adjuvant treatment suggestion was made for 7 (25%) patients with a high risk of recurrence in the multidisciplinary tumor council. Partial response was observed in 1 (3.5%) of the 2 (7.1%) metastatic patients, and stable disease was observed in the other. Recurrence was detected in 22 (84.6%) patients . Fifteen (53.6%) patients died during the follow-up period. Survival was better in premenopausal patients (99.2 versus 51.6 months, P = 0.056). No significant difference was found when the survival of patients who received and did not receive adjuvant treatment were compared. In relapsed patients, there was no significant difference in survival between patients who underwent and did not undergo surgical treatment.Conclusions Uterine LMS is a rare and aggressive malignancy with limited diagnostic methods, frequent recurrences, high mortality, and limited use of nonsurgical treatments. The positive effect of adjuvant treatment on survival has not been demonstrated. Further studies are needed to investigate the effect of hormone receptor status on prognosis and new biomarkers.
