The purpose of the present study was to clarify clinical outcomes of elderly patients with soft tissue sarcoma who underwent surgery neither with neoadjuvant nor adjuvant chemotherapy. The median follow-up period was 46.3 (range 6.7-99.0) months. All patients underwent surgical resections. R0 margins were achieved in 24 cases (92.3%) and R1 margins in 2 cases (7.7%). The 1-, 2-, and 5-year sarcoma-specific survival (SSS) rates were 92.3%, 88.5%, and 83.8%, respectively. Multivariate analysis showed no significant risk factors for SSS. No significant relationship of histological grades and local recurrences (P = .56) or distant metastases (P = .54) was shown. In the current study, we observed a comparable survival ratio, despite no neoadjuvant or adjuvant chemotherapies performed. Tumor resections with adequate margins might, at least in part, have contributed to the decent survival ratio regardless of histological grade. Twenty-six consecutive patients aged ≥ 70 years, who underwent surgical resections of soft tissue sarcoma between January 2013 and December 2019, were included. SSS were analyzed by the Kaplan-Meier method, and the relationships between SSS and clinical parameters were evaluated by Cox proportional hazards analysis.
