Abstract only 10057 Background: There are no data regarding the management and the outcome of elderly patients (pts) diagnosed with advanced soft-tissue sarcoma (STS). Methods: The charts of pts aged ≥ 75 years and diagnosed with metastatic and/or unresectable STS between 1990 and 2011 at Memorial Sloan Kettering (New York) and Institut Bergonié (Bordeaux, France) were reviewed. Results: 189pts were included.Median age was 79 years (range 75-93).160 pts (84.5%) had metastatic disease. The most frequent histological subtype was leiomyosarcoma (n=57, 30%). The median age-adjusted Charlson comorbidity score was 10 (range 5-17). 120 pts (63.5%) received systemic therapy whereas 69 pts (36.5%) were managed with best supportive care (BSC) only. Pts who received BSC only were more likely ≥ 80 years old (58% versus 38%, p=0.01) and with performance status (PS) ≥ 2 (35% versus 14%, p=0.01). Single agent and combination therapy were delivered in 87 (72.5%) and 33 (27.5%) cases respectively. 67 pts (56%) received a 1 st -line anthracycline-containing regimen. The median progression-free survival of pts treated with systemic therapy was 4 months (95% CI: 2.5-5.5). 21 pts (17.5%) had to stop 1 st line treatment because of toxicity. On multivariate analysis, age ≥ 80 years, PS ≥ 2, and single-agent therapy were significantly associated with poor PFS. 51 pts received one or more further lines of therapies. At the time of analysis, 170 pts (90%) had died. 96% of deaths were related to the disease. The median OS for the entire cohort of pts was 9.6 months (95% CI: 7.3-12). The 1-year and 2-year OS rates were 43% (95% CI: 36–50), and 22% (95% CI: 16–28), respectively. The median OS of pts managed with systemic therapy and BSC were 12.5 months (95% CI: 8.4-16.6) and 5.1 months (95% CI: 3.7-6.5), respectively (p=0.02). However, on multivariate analysis, PS ≥ 2 and age-adjusted Charlson score ≥ 10 were the sole independent factors significantly associated with OS. Conclusions: A high proportion of elderly pts with advanced STS were considered unfit for chemotherapy. The OS of STS pts ≥ 75 years who were managed with systemic therapy seems similar to that of younger pts. Further efforts are needed to better define the optimal care for fit and unfit elderly pts with advanced STS.
