Treatment of uterine sarcoma at the Royal Marsden Hospital from 1974 to 1998.
OBJECTIVE
Uterine sarcomas are rare tumours with histopathological diversity characterised by rapid clinical progression and poor prognosis. Optimal management consists of complete surgical removal, but is not clear whether adjuvant radiotherapy improves the prognosis. The aim of this retrospective study was to investigate the clinical and histopathological characteristics together with treatment and outcome of patients with uterine sarcomas.


METHODS
Records of 100 patients treated at the Royal Marsden Hospital between 1974-1998 were reviewed: 47 leiomyosarcoma (LMS), 30 mixed mullerian tumours (MMT), 19 endometrial stromal sarcoma (ESS), one haemangiopericytoma, one rhabdomyosarcoma and two unspecified sarcoma. There were 50, 11, 21 and 18 patients with stage I, II, III and IV carcinoma, respectively. Thirty-four patients had high-grade disease. Fifty-three patients received adjuvant radiotherapy. The median age was 55 years (range: 18-83 years). The median follow-up was 54 months (range: 3 months to 27 years).


RESULTS
The overall 3, 5 and 10-year survival rates were 39%, 30% and 20%, respectively. Survival was significantly related to stage (P = 0.002), grade (P = 0.003) and histological type (P = 0.04), but not to use of postoperative irradiation. At 3 years, the survival rate was 42% for LMS, 22% for MMT and 63% for ESS. Local recurrence rate, however, was significantly improved after adjuvant radiotherapy with dose higher than 50 Gy (P = 0.001).


CONCLUSIONS
Prognosis is dependent on histopathological sub-type, grade and tumour stage. Adjuvant radiotherapy decreases local recurrence rate, but without significant impact on survival.
