Significance of local treatment in patients with metastatic soft tissue sarcoma.

Metastatic soft tissue sarcomas (STS) represent enormous challenges to improve the low survival rate, which is almost the same as past 2 decades ago, although surgery, radiotherapy and radiofrequency ablation has been accepted in the treatment of metastatic STS. Moreover, STS varies between elderly and younger victims in the aspect of diagnoses, prognosis, and treatment strategies. In order to evaluate the role of local treatment in improving prognosis for patients with metastatic STS and select the proper candidates who will benefit from local therapy, a single-institution nearly 50-year experience were collected and reviewed. Finally, we found that local treatments could improve treatment response and survival, but overall survival advantage could not be seen in elderly patients. This conclusion from a single institution could serve as a basis for future prospective multi-institutional large-scale studies.
