Abstract

Objective: To explore the yield and impact of perioperative imaging on management among patients undergoing surgical resection and treatment of uterine sarcomas. Methods: A retrospective chart review was done for women with histologically confirmed uterine sarcomas treated at Barnes Jewish Hospital/Washington University from 2001 to 2007. Descriptive statistics, Cox multivariate models, and Kaplan-Meier plots were used to evaluate associations and survival. Results: A total of 92 patients were identified and 55 (60%) were diagnosed with stage III-IV disease. Perioperative imaging was obtained in 84 (91%) cases, including chest X-ray in 66 (72%), computerized tomography (CT) of the abdomen and pelvis in 59 (64%), chest CT in 33 (36%), positron emission tomography (PET) in 8 (9%), and CT of the head, pelvic magnetic resonance imaging (MRI), or bone scan in a total of 2 (2.2%). Imaging identified abnormalities concerning for metastases in 30 (32%) studies. Thirty-four recurrences have been documented, and 21 (62%) of these treatment failures were extrapelvic. Multivariate analysis of this series noted that tomographic evidence of extrauterine disease predicted recurrence (p = 0.028) and incomplete surgical resection (p = 0.003, HR 6.0 95% CI 1.9-19.9) predicted disease-free survival. Imaging contributed to change in surgical and post-surgical treatment decisions in 8 (9%) patients. Conclusion: Pretreatment imaging studies change management in a minority of patients with newly diagnosed uterine sarcomas.
