Uterine sarcomas: A clinicopathological analysis of 13 cases in a tertiary care centre
Abstract
Introduction: Uterine sarcomas are rare tumors arising from mesodermal tissue of uterus which accounts for 1-3% of all female genital tract malignancies. They are characterized by rapid clinical progression and poor outcome. The purpose of this study was to analyze the clinicopathological features of uterine sarcoma and their treatment outcome.
Materials and Methods: A retrospective review of clinical and pathological characteristics of patients with primary uterine sarcoma was done at Kasturba Hospital, Manipal between January 2013 and December 2018. Patients were staged using the 2018 FIGO histological classification for uterine cancer.
Results: A total of 13 patients with uterine sarcoma were reviewed. All cases were multiparous women with the median age of presentation of 51.5 years (range: 40-80 years). The histopathological types were carcinosarcoma (five cases), endometrial stromal sarcoma (four cases), leiomyosarcoma (two cases), one case each of adenosarcoma and PEComa. Ten cases were FIGO clinical stage I, two in stage II and one in stage III. All patients underwent a total abdominal hysterectomy, whereas adjuvant chemotherapy and radiotherapy were given for only four patients. All cases were followed up clinically and radiologically with no recurrence over a maximum follow-up period of 12 months.
Conclusion: Uterine sarcoma is an uncommon neoplasm with carcinosarcoma being the most common. The prognosis of uterine sarcomas depends on the histological subtype, grade and stage of the tumor at diagnosis. Adjuvant radiotherapy helps in better local control and reduces the recurrence rate.
