Clinical Trial Summary

The purpose of this study is to learn whether the profile of RNA from circulating exosomes can be used as a biomarker for lung metastases of primary high-grade osteosarcoma. Circulating exosomes plays roles in metastases in many kinds of cancer including osteosarcoma. By RNA profiling researchers may find lung metastases earlier than conventional work-up and predict the oncological outcomes.


Clinical Trial Description

Investigators have performed a 4 patients pilot study under the oversight of hospital's ethics committee, and investigator found that the levels and mutations of circulating exosome RNA from patients with or without lung metastasis have significant differences. Then investigators wish to register this study to do a further research, in order to reveal the roles of circulating exosome RNA in metastases of osteosarcoma. ;
