Uterine sarcoma: twenty-seven years of experience.

PURPOSE

A correlation of treatment for uterine sarcoma with outcome, prognostic importance of pathology, and clinical parameters.

PATIENTS AND METHODS

One hundred forty-one patients (median age: 56 years, range: 19-85 years) with a histologically verified uterine sarcoma were identified from a database compiled at the Royal Marsden Hospital and the University of Florence between 1974 and 2001. Seventy-two patients had leiomyosarcoma, 42 had mixed müllerian tumors, 22 had endometrial stromal sarcoma, 1 hemangiopericytoma, 1 rhabdomyosarcoma, and 3 patients had unspecified sarcoma. According to FIGO classification, Stage I, II, III, and IV tumors were identified in 71, 13, 31, and 26 patients, respectively.

RESULTS

At the time of analysis, 73.7% of patients were dead, and 26.3% were alive with a median survival of 2 years from initial diagnosis. Univariate analysis for cause-specific survival demonstrated statistical significance for histology (p = 0.02), grade (p = 0.003), stage (p = 0.007), and age (p = 0.02). Multivariate analysis demonstrated significant prognostic values for stage (p = 0.02) and histology (p = 0.05) only. Postoperative radiotherapy with a total dose higher than 50 Gy seems to be significant (p = 0.001) in reducing local recurrence.

CONCLUSIONS

Our data favor treatment for Stages I, II, and III of uterine sarcoma with radical surgery plus radical dose irradiation comprising both external beam radiotherapy and brachytherapy.
