Trial Summary

Do I need to stop my current medications for the trial?

The trial protocol does not specify whether you need to stop taking your current medications.

What data supports the effectiveness of the treatment DOTATATE-PET for meningioma?

The research shows that 68Ga-DOTATATE PET scans are more effective than traditional MRI in detecting meningiomas, especially when the tumor extends into the bone, which is crucial for planning treatment and assessing recurrence.12345

How does the DOTATATE PET scan treatment differ from other treatments for meningioma?

The DOTATATE PET scan treatment is unique because it uses a special imaging technique to detect meningioma tissue by targeting somatostatin receptors, which are often present in these tumors. This method is more sensitive than traditional MRI in identifying the spread of the tumor into the bone, helping in better diagnosis and treatment planning.23567

What is the purpose of this trial?

68Ga-DOTATATE-based radionuclides are a novel modality in the diagnosis and treatment of central nervous system meningioma. DOTATATE is a ligand for the SSTR (somatostatin receptor), which is expressed in meningioma but not in normal brain or bone. It is also more effective than MRI in delineating tumor, which is the current imaging standard for assessing meningioma. For radiation planning, it can help to reduce the risk of geometrical miss, identify area that require dose-escalation, and reduce dose to normal tissue. The purpose of the study is to compare the radiation therapy (RT) contouring and planning for meningioma with and without the use of 68Ga-DOTATATE-PET

Interventions

  • DOTATATE-PET
Trial Overview The study is testing if using a DOTATATE-PET scan before radiation therapy helps better plan the treatment for meningiomas compared to standard MRI scans alone. The goal is to see if this leads to more accurate targeting of tumors while sparing healthy tissue.

Findings from Research

In a study of 20 patients with meningiomas, [68Ga]-DOTATATE PET/MRI successfully confirmed recurrent tumors in 85% of cases, demonstrating its effectiveness in distinguishing between tumor recurrence and post-treatment changes.
The novel quantitative analysis approach used in this study showed a significant difference in uptake values between meningiomas and post-treatment changes, suggesting that [68Ga]-DOTATATE PET/MRI could enhance diagnostic accuracy and treatment planning for meningioma patients.
