Tenosynovial Giant Cell Tumors (TGCT) Observational Platform Project

TGCT is a rare disease that is difficult to manage, surgical resection is the primary treatment currently available. To date no disease registry exists and there is little data available detailing the management of patients with diffuse TGCT (d-TGCT), the burden of d-TGCT for patients (including pain, joint stiffness, swelling, reduced mobility and quality of life) or the economic impact of d-TGCT. This study aims to collect data by an observational disease registry involving no intervention to the patient or changes to investigators treatment decisions.
