简要总结
This is a multicenter, randomised phase II trial in patients with high risk GCT.
Primary objective:
- Determine if adjuvant zoledronic acid improves the 2 years recurrence rate of 'high risk' GCT as compared to standard care
Secondary objectives:
- Determine the relapse free survival
- Evaluate the usefulness of bone remodelling markers in diagnosing and monitoring GCT
详细描述
GCT is a potentially malignant tumour that presents with a locally destructive osteolytic lesion. The high risk GCT are characterized by a high recurrence rate around the 40-45%. Zoledronic acid is a potent inhibitor of osteolysis and is capable of inducing osteoclast and stromal cell apoptosis, which makes it an attractive adjuvant treatment in 'high risk' GCT in order to improve clinical outcomes and reduce the recurrence rate.
