Abstract
BACKGROUND: Although rare, uterine sarcomas account for a high proportion of uterine cancer mortality. Treatment options and robust trial data are limited. OBJECTIVES: The TOURISM study (Treatment Outcomes in UteRIne SarcoMa) is a UK-wide study by the National Oncology Trainees Collaborative for Healthcare Research which aimed to characterise this patient cohort. DESIGN: A retrospective descriptive cohort study. Patients with carcinosarcomas/mixed Mullerian tumours, non-uterine gynaecological sarcomas and uterine metastases were excluded. Routine clinical data, including general patient demographics, diagnosis, treatment and outcomes, were collated and pseudonymised. SETTING: Patients diagnosed with uterine sarcoma in the UK National Health Service between 1 January 2008 and 31 December 2017 were identified from electronic records. PARTICIPANTS: A total of 406 patients from eight centres were eligible for inclusion. RESULTS: The median age at diagnosis was 56 years, with leiomyosarcoma the most common diagnosis (54.4%). The majority (57.9%) were diagnosed at the International Federation of Gynecology and Obstetrics stage I, with 19.7% diagnosed at stage IV. Nearly half (45.2%) of the patients received at least one line of chemotherapy, of which most (81.0%) received doxorubicin first-line. In the stage I group 7.4% received adjuvant chemotherapy and 15.0% received adjuvant radiotherapy. Median overall survival was 37 months; however, survival varied significantly by stage at diagnosis (stage I: 105 months; stage II: 33 months; stage III: 19 months; stage IV: 14 months). CONCLUSIONS: Our data highlight the diversity in patient management in uterine sarcoma and a marked survival advantage for patients diagnosed with stage I disease. These data highlight the importance of a multidisciplinary approach and describe real-world trends in systemic therapies, radiotherapy and surgical treatment in this rare cancer type.
