Limitations and caveats
Twenty-five patients were required for the analysis to have 80% power to detect improvement in PFS-6 from 5% to 25% with a significance level of 0.05, and accounting for a 10% drop-out rate. The study was terminated after accrual of 18 patients, due to slow accrual and lack of efficacy

ListOutcomeTime frameDescription
PrimaryProgression Free Survival (PFS)6 months after starting treatment
6 months PFS refers to the percentage of patients in a study who remain alive and whose disease has not worsened 6 months after starting treatment. To determine the 6 months PFS rate for patients with recurrent or progressive meningioma on pembrolizumab therapy we used the RANO meningioma criteria. The Response Assessment in Neuro-Oncology meningioma criteria are guidelines used to evaluate treatment response in meningioma patients, incorporating both radiological and clinical factors. Tumor response is classified into categories such as: complete response (CR), where the tumor disappears. Partial response (PR) with a 50% or more reduction in tumor size. Minor response (MR) between 25% to 50% reduction in tumor size. Stable disease (SD) indicating minimal change, and progressive disease (PD) defined by at least a 25% increase in tumor size, new lesions, or worsening clinical symptoms. these criteria emphasize the use of consistent imaging techniques such as MRI.
PrimaryProgression Free Survival (PFS)12 months after starting treatment
12 months PFS refers to the percentage of patients in a study who remain alive and whose disease has not worsened 12 months after starting treatment. To determine the 12 months PFS rate for patients with recurrent or progressive meningioma on pembrolizumab therapy we used the RANO meningioma criteria. The Response Assessment in Neuro-Oncology meningioma criteria are guidelines used to evaluate treatment response in meningioma patients, incorporating both radiological and clinical factors. Tumor response is classified into categories such as: complete response (CR), where the tumor disappears. Partial response (PR) with a 50% or more reduction in tumor size. Minor response (MR) between 25% to 50% reduction in tumor size. Stable disease (SD) indicating minimal change, and progressive disease (PD) defined by at least a 25% increase in tumor size, new lesions, or worsening clinical symptoms. these criteria emphasize the use of consistent imaging techniques such as MRI.
SecondaryOverall Survival (OS)from date of diagnosis until date of death from any causeOverall survival (OS) is a term used in reference to treatments for cancer. It refers to the time which begins at diagnosis and up to the time of death.
SecondaryOverall Progression Free Survival (PFS)From the initiation of treatment to the occurrence of disease progression or death.
