Synovial Sarcoma Registry / Biospecimen Repository

This study will enroll patients with a diagnosis of Synovial Sarcoma.

Following consent, demographic, clinical, treatment and outcome data will be collected from an interview and/or online survey. This will include a request for contact information for the subject's treating hospitals/physicians and a release of records request to obtain medical records.

At approximately 6-12 month intervals for up to 10 years after initial diagnosis and/or relapse, subjects and/or their treating hospitals may be contacted to provide updates on treatment and outcomes.

Tumor samples may be collected from residual material obtained during clinically indicated procedures occurring before or after consent to this study. No additional material will be collected or procedures performed solely for the purpose of this study.

Blood may be collected at the participant's local institution at the time of a clinically indicated blood draw and/or saliva or a buccal swab may be collected as a germline sample and for analysis of circulating free DNA (cfDNA) and/or circulating tumor cells (CTCs).

Genetic testing may be performed on tumor and germline samples submitted by subjects. Results will only be returned if deemed clinically significant.
