Somatostatin Receptor PET Imaging to Guide Radiotherapy Dose Escalation in High Risk Meningiomas. (SPIDER-MEN)

February 11, 2025 updated by: Centro di Riferimento Oncologico - Aviano
High-risk meningiomas always require postsurgical radiation treatment. Recent evidence has shown that increased radiation therapy dose may be associated with increased intracranial control of disease. In order to better define the volume of radiation treatment, the addition of PET imaging with somatostatin receptor tracers adds additional information compared to encephalon MRI with MoC alone.The present study aims to investigate whether radiation treatment with higher doses than the standard and defined using PET imaging can be safe and at the same time effective in order to increase progression-free survival in high-risk meningiomas.

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Incidence of brain radionecrosis
Time Frame: up to 13 years
Incidence of symptomatic brain radionecrosis (grade >=2 defined according to CTCAE scale v5.0).

Secondary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Overall survival (Overall survival = OS)
Time Frame: up to 13 years
Overall survival (OS) will be defined as time between enrollment and death

Incidence of other toxicities
Time Frame: up to 13 years
Incidence of other neurological toxicities graded using the CTCAE scale v. 5.0
up to 13 years
Concordance between GTV-RM and GTV-PET
Time Frame: up to 13 years
Concordance will be measured according to Dice Similarity coefficient
