Prospective Observational Basket Study of Stereotactic Body Radiation Therapy for OligoMetastatic Patients From Rare Tumors
Trial Parameters
Brief Summary
This prospective observational study aims to investigate the effectiveness and safety of SBRT in the management of oligometastases from rare tumors. In addition, the study aims to identify potential differences in treatment efficacy and toxicity between different types of cancer and to provide valuable information on the use of SBRT in these contexts, potentially leading to better treatment options and outcomes for these patients.
Eligibility Criteria
