Extremity high-grade sarcomas in elderly patients, are they candidates for surgery? Experience in a sarcoma referral center.

The number of elderly patients diagnosed with cancer is increasing. However, knowledge regarding cancer in elderly patients is very scarce. The aim of this study is to analyze the differences in management and outcomes of high-grade extremity sarcomas between elderly and middle-aged patients. Two cohorts were made (> 70 and 30/50 years old) among patients treated in a multidisciplinary unit of a national reference center between 2011 and 2017 with a minimum of 2 years of follow-up. The management and outcomes between these two cohorts were compared. Seventy patients were included, 34 young patients and 36 elderly patients. The only difference between the treatment schemes was the chemotherapy used, 67.6% of the young patients received chemotherapy versus 16.7% of the elderly patients (p = 0.000015). There were no differences either in the overall survival or the progression-free survival between groups at 1 and 2-year follow-up. Deceases for other causes were nearly exclusive of elderly patients at a median of 45.57 months. Surgery is the treatment of choice for sarcomas in both elderly and young patients having similar results in terms of progression-free survival, overall survival, and surgery outcomes. The use of chemotherapy is the only difference in the treatment schemes between both groups. In the elderly patient with minimal or no comorbidity and good functional reserve, surgical curative treatment should be chosen. As for frail elderly patients, the therapeutic objectives must be focused mainly on quality of life and palliation of symptoms.
