Background The surgical management of soft tissue sarcoma (STS) in elderly patients has only been addressed in a few studies. The objective of the current study was to assess surgical outcomes in patients with STS aged 70 years and older and the association of older age with the survival after complete resection. Methods A retrospective analysis was conducted in 158 elderly patients with localized STS who visited 11 institutions participating in Japanese Musculoskeletal Oncology Group between 1995 and 2006 and were treated by surgical resection. Univariate and multivariate analyses were performed to identify prognostic factors. Results Median follow-up period was 38 months. Histologically high-grade tumors were detected in 71% of the patients. Wide resection with adequate margins was performed in 66% of the cases. Systemic chemotherapy was performed in only 5 patients. Univariate analysis identified histological grade and gender as statistically significant prognostic factors for sarcoma-specific survival. Multivariate analysis did not identify significant prognostic factors for sarcoma-specific survival, although high grade sarcoma emerged as a potentially significant prognostic factor (P = 0.050). Local recurrence was detected in 19% of the patients. Multivariate analysis of local recurrence-free survival showed that tumor site and surgical margins were statistically significant prognostic factors. Conclusions Older age was not identified as a prognostic factor for sarcoma-specific survival, which is not consistent with the findings of previous studies showing that older age was associated with decreased sarcoma-specific survival. Complete resection should be indicated and can lead to optimal treatment outcome for properly selected elderly patients.
