Abstract:
10042 Background: 40-50% of sarcomas become metastatic. Median survival of metastatic patients has improved over time. The probably multifactorial reasons for such improvement are not fully clear. Noteworthy, for patients with a controlled primary and a limited number of lung metastases, complete resection of their metastases yields survival rates of up to 40% at three years. Advances in surgery, radiotherapy and radiofrequency have fostered the use of local treatments for various metastatic sites (lung, liver, spine...). Methods: A multicentric retrospective study of the Groupe Sarcome Francais (GSF-GETO); approved by the nationally-review board and ethical committee, was conducted to assess the impact of local ablative treatment on overall survival. Patients who had had oligometastases (any site, 1-5 synchronous metastases) at diagnostic or during the course of disease between 2000 and 2010 were included. Results: Median age of the 243 oligometastatic sarcoma patients was 53 years-old (11-86). Patients had grade I, II and III in 7.5%, 29.6% and 63.3% of cases, respectively with various histologies. 69% of patients underwent local ablative treatment of metastases. Median follow-up was 59 months (4-212) for living patients. Median overall survival was 51 months (1-348). On univariate analysis, grade, histology, absence of chemotherapy, local ablative treatment (surgery, irradiation, radiofrequency or chemoembolisation) correlated with survival but not age or site of oligometastasis. On multivariate analyses, grade (hazard ratio HR 0.12 [CI95 0.3-0.6]) and local ablative treatment (HR 3.8 [CI95 2.1-7.1] ) remained significant. Conclusions: Local ablative treatment of metastases is associated with better survival in sarcoma patients with oligometastatic disease. The role of the locoregional treatment of metastases and its impact on quality of life should be assessed prospectively.
