OBJECTIVES: The aim of this study was to analyze patterns of care in elderly soft tissue sarcoma (STS) patients and their impact on clinical outcome and treatment-related toxicity. MATERIALS AND METHODS: We retrospectively collected data of >65-year-old patients diagnosed with locally advanced STS between 1991 and 2017 in a single institution. RESULTS: The study included 111 patients: 105 (94.6%) patients underwent surgery, associated with preoperative (n=19, 17.1%) or postoperative radiotherapy (n=72, 64.8%). Anthracycline-based chemotherapy was prescribed in 41.4% of patients (n=46). Acute grade ≥3 postoperative radiotherapy-related radiation dermatitis and all grades of chemotherapy-induced neutropenia were significantly correlated to age >80 years (P=0.02) and >70 years (P=0.045), respectively. The mean follow-up was 4.1 years (range, 0.1 to 17.7). Three-year and 5-year local recurrence-free survival were 80.3% and 75.7%, respectively; neither treatment-related nor patient-related characteristics affected local recurrence. Three-year and 5-year distant relapse-free survival were 59.6% and 44.6%, respectively. On multivariate Cox regression, undifferentiated pleomorphic sarcoma histology and Charlson Comorbidity Index >7 were independent factors associated with distant relapse-free survival (P=0.026 and P=0.0001). Overall survival was 62% and 46.6% at 3 and 5 years, respectively. On multivariate Cox regression, surgery and Charlson Comorbidity Index <7 were independent factors associated with overall survival (P=0.006 and P=0.0001). CONCLUSIONS: In this study, elderly STS patients receiving a tailored treatment encompassing surgery, radiotherapy, and/or chemotherapy obtained an improved outcome, although caution is advised because of increased toxicity in relation to age. Comorbidities should be considered to offer the best treatment option to this frail patient population.
