Clinical Trial Summary

A greater extent of resection of the contrast-enhancing (CE) tumor part has been associated with improved outcomes in high-grade glioma patients. Recent results suggest that resection of the non-contrast-enhancing (NCE) part might yield even better survival outcomes (supramaximal resection, SMR). Therefore, this study evaluates the efficacy and safety of SMR with and without mapping techniques in HGG patients in terms of survival, functional, neurological, cognitive, and quality of life outcomes. Furthermore, it evaluates which patients benefit the most from SMR, and how they could be identified preoperatively. This study is an international, multicenter, prospective, 2-arm cohort study of observational nature. Consecutive HGG patients will be operated with supramaximal resection or maximal resection at a 1:3 ratio. Primary endpoints are: 1) overall survival and 2) proportion of patients with NIHSS (National Institute of Health Stroke Scale) deterioration at 6 weeks, 3 months, and 6 months postoperatively. Secondary endpoints are 1) residual CE and NCE tumor volume on postoperative T1-contrast and FLAIR MRI scans 2) progression-free survival; 3) onco-functional outcome, and 4) quality of life at 6 weeks, 3 months, and 6 months postoperatively. The study will be carried out by the centers affiliated with the European and North American Consortium and Registry for Intraoperative Mapping (ENCRAM).


Clinical Trial Description

This is an international, multicenter, prospective, observational, 2-arm cohort study (registration: clinicaltrials.gov ID number TBA). Eligible patients are operated with supramaximal resection versus maximal resection with a 1:3 ratio with a sequential computer-generated random number as subject ID. Intraoperative mapping techniques and/or surgical adjuncts can be used in both treatment arms to ensure the safety of the resection (to minimize the risk of postoperative deficits). Supramaximal resection is defined as 0 cm3 CE tumor and 5 cm3 or less NCE tumor, whereas maximal resection is defined as 0 cm3 CE tumor and >5 cm3 NCE tumor (in line with the updated RANO criteria). Study patients are allocated to either the supramaximal or maximal safe resection group and will undergo evaluation at presentation (baseline) and during the follow-up period at 6 weeks, 3 months, and 6 months postoperatively. Motor function will be evaluated using the NIHSS (National Institute of Health Stroke Scale) scale. Language function will be evaluated using a standard neurolinguistic test-battery consisting of the Aphasia Bedside Check (ABC), Shortened Token test, Verbal fluency, Picture description and Object naming. Cognitive function will be assessed using the Montreal Cognitive Assessment (MOCA). Patient functioning with be assessed with the Karnofsky Performance Scale (KPS) and the ASA (American Society of Anesthesiologists) physical status classification system. Health-related quality of life (HRQoL) will be assessed with the EORTC QLQ C30, EORTC QLQ BN20 and EQ 5D questionnaires. Overall survival and progression-free survival will be assessed. We expect to complete patient inclusion in 4 years. The estimated duration of the study (including follow-up) will be 5 years. The primary study objective is to evaluate the safety and efficacy of supramaximal resection versus safe maximal resection in HGG patients as measured by overall survival (OS) and postoperative NIHSS deterioration. Secondary study objectives are to evaluate extent of resection of CE and NCE tumor, quality of life, progression-free survival (PFS), onco-functional outcome (OFO), and SAEs after SMR or maximal safe resections as measured by volumetric analyses of contrast-enhanced MRI images with gadolinium combined with FLAIR images, tumor progression on MRI scans, quality of life questionnaires (EORTC QLQ C30, EORTC QLQ BN20, EQ 5D), combining postoperative residual volume with NIHSS outcomes, and recording SAEs respectively. Patients will be recruited from the neurosurgical or neurological outpatient clinic or through referral from general hospitals of the participating neurosurgical hospitals, located in Europe and the United States. The study is carried out by centers from the ENCRAM Consortium. ;
