Official title
Phase II Pilot Randomized Controlled Trial to Assess Feasibility of "Supra-marginal" Surgical Resection of Malignant Glioma
Brief summary
Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.
G-SUMIT is a pilot, phase II,randomized controlled trial to evaluate the feasibility of performing a large-scale trial in patients undergoing surgery for first-time diagnosis of high grade glioma (HGG) in a surgically favorable anatomical location to answer the following: Does extending the margin of resection 1 cm beyond visible enhanced volume on MRI result in (a) an increase in overall survival? (b) result in a similar rate of "clinically-significant" neurological worsening during 30 days post surgery and quality of life at 6 and 12 months?
