Abstract:
2056 Background: Glioblastoma represents the most aggressive primary brain tumor in adults, and less than 5% of patients survive 5 years from diagnosis. Factors influencing this long-term survival are poorly understood. Methods: In cooperation with the European Organisation for Research and Treatment of Cancer (EORTC) in Brussels, Belgium, more than 20 clinical sites in the US, Europe and Australia have registered patients with centrally confirmed glioblastoma who survived ≥ 5 years, collecting clinical data including therapy and quality of life-related factors, as well as biospecimens allowing to analyse molecular and immunological parameters. Results: At the cut-off of December 31, 2018, 392 patients were registered, of which 232 had glioblastoma confirmed by central pathology review; 59 dropped out due to histology other than glioblastoma. Glioblastomas were isocitrate dehydrogenase (IDH)-wildtype in 70.7% and had a positive O 6 -methylguanine DNA methyltransferase (MGMT) promotor methylation status in 75.9%. Median age at diagnosis was 52 years (range: 21-77 years). There was enrichment for patients with gross total resection. Further analyses are ongoing. Conclusions: In a comprehensive effort, the consortium funded by the US Brain Tumor Funders’ Collaborative characterizes factors modulating long-term survival in glioblastoma in a unique large patient cohort. Clinical trial information: NCT 03770468.
