CLRM-07 RANO 2.0: PROPOSAL FOR AN UPDATE TO THE RESPONSE ASSESSMENT IN NEURO-ONCOLOGY (RANO) CRITERIA FOR HIGH- AND LOW-GRADE GLIOMAS IN ADULTS

چکیده

Abstract The Response Assessment in Neuro-Oncology (RANO) criteria for high-grade gliomas (RANO-HGG) and low-grade (RANO-LGG) were developed to improve the reliability of response assessment glioma trials. Over time some limitations these identified, uncertainty emerged regarding integrating features modified RANO (mRANO) or immunotherapy (iRANO) criteria. Informed by data from a cohort glioblastoma patients other evaluations that allowed evaluation different criteria, we propose updates (RANO 2.0). Based on 2021 WHO classification gliomas, recommend standard set both high be used all trials regardless treatment modalities being evaluated. In newly diagnosed setting, post-radiotherapy MRI, rather than post-surgical will as baseline future comparison. Since incidence pseudoprogression is 12 weeks following radiotherapy, continuation confirmation progression during this period with repeat histopathologic evidence unequivocal recurrent tumor, required define tumor progression. However, scans are not mandatory after nor tumors. For treatments likelihood pseudoprogression, MRI an option. primary measurement remains maximum cross-sectional area (2-dimensional) but volumetric measurements IDH-wildtype glioblastoma, non-enhancing disease no longer IDH-mutated tumors significant component, clinical may require evaluating enhancing components assessment.

Updated response assessment criteria for high-grade gliomas: response assessment in neuro-oncology working group.

Currently, the most widely used criteria for assessing response to therapy in high-grade gliomas are based on two-dimensional tumor measurements on computed tomography (CT) or magnetic resonance imaging (MRI), in conjunction with clinical assessment and corticosteroid dose (the Macdonald Criteria). It is increasingly apparent that there are significant limitations to these criteria, which only ...

Response assessment criteria for brain metastases: proposal from the RANO group.

CNS metastases are the most common cause of malignant brain tumours in adults. Historically, patients with brain metastases have been excluded from most clinical trials, but their inclusion is now becoming more common. The medical literature is difficult to interpret because of substantial variation in the response and progression criteria used across clinical trials. The Response Assessment in...

Response Assessment Criteria for Glioblastoma: Practical Adaptation and Implementation in Clinical Trials of Antiangiogenic Therapy

Since 1990, the primary criteria used for assessing response to therapy in high-grade gliomas were those developed by Macdonald and colleagues, which incorporated 2-dimensional area measurements of contrast-enhancing tumor regions, corticosteroid dosing, and clinical assessment to arrive at a designation of response, stable disease, or progression. Recent advances in imaging technology and targ...
