Objective:
To review the survival outcomes in patients with endometrial stromal sarcoma (ESS) in Cancer Hospital, Peking Union Medical College, Chinese Academy of Medical Sciences, and to discuss prognostic factors and the role of post-operative adjuvant radiotherapy and chemotherapy.
Methods:
Hospital records and pathology reports for 97 patients with ESS were reviewed. Among 97 patients, 69 had low-grade ESS (LGESS), 16 had high-grade ESS (HGESS) and 12 had unclear grade. The median age at diagnosis was 44.0 years. The median follow-up time was 62 months (5 - 277 months). Atypical vaginal bleeding (43%) and prolonged and increased menses (36%) were the main symptoms.
Results:
Totally 2-year and 5-year cumulative survival rates were 93% and 84%, respectively. Cumulative survival curves were significantly different between LGESS and HGESS, and so did cumulative survival curves between stage I - II and stage III - IV (P < 0.05). Totally, 34 patients (37%) had local or distant recurrence. The median time-to-recurrence (TTR) was 27 months. The recurrence rates of the patients with or without preserve of ovary were 89% and 24%, respectively (P = 0.000). The local-control-rates of the patients who received or did not receive post-operative radiotherapy were 81% and 43%, respectively (P = 0.011).
Conclusions:
The prognosis of HGESS is obviously worse than that of LGESS. The risk of recurrence of patients with preserve of ovary was remarkably higher than that of patients without preserve of ovary. Postoperative radiotherapy could increase the local-control-rates.
