Uterine leiomyosarcomas are infrequent and aggressive malignancies of female genital tract.


Data of 54 uterine leiomyosarcoma patients who were diagnosed and treated at 4 different centers from November 2000 to October 2010 were analysed retrospectively.


Mean age was 50.8 years (range 34-72), and 54.9% of patients were premenapousal. According to last International Federation of Gynecology and Obstetrics (FIGO) staging system, 26 (48.1%) patients had stage I disease, 14 (25.9%) stage II, 5 (9.3%) stage III, and 9 (16.7%) stage IV. Of the 52 patients who underwent surgery, 38.4% (20 patients) were given adjuvant chemotherapy, 17.3% (9 patients) adjuvant radiotherapy, 23% (12 patients) adjuvant sequential chemotherapy and radiotherapy. Median relapse free survival (RFS) was 19 months. One, 2 and 5 year RFS were 65.2%, 42.6%, 17.2% respectively. Median overall survival (OS) was 56 months, OS after 1, 2, 5 years were 87.7%, 78.7%, 41.9% respectively. Clinicopathologic parameters that were statistically evaluated included age (<60 or ≥60 years), body mass index (80% of patients were obese or overweight), stage of disease, grade (83.3% of patients had grade 2-3 tumor), tumor size [mean 8.8cm (range 2-17.5)], mitotic activity [mean count 15.6/10 high-power fields (range 2-42)], presence of tumor cell necrosis (31 cases), presence of residual tumor after surgery (13 cases) and type of treatment procedure. After mutivariate analysis, age < 60 years (p = 0.022, HR: 4.52), low grade tumor (p = 0.019, HR: 5.18) and adjuvant treatment with sequential chemotherapy and radiotherapy after surgery (p = 0.020, HR: 0.14) were associated with longer OS.


Uterine sarcomas have poor prognosis. We have concluded that favorable prognostic factors affecting OS are younger age, lower grade and to be treated with adjuvant sequential chemotherapy and radiotherapy.
