Invasion of the surrounding brain is a key feature of glioblastomas and major cause of treatment failure. The degree of invasion varies in individuals. We have assessed the invasive phenotype of 21 glioblastoma patients receiving similar treatment using the pq decomposition method. We have shown that 20% of patients have a minimally invasive phenotype. These patients have a longer time to progression and are more likely to be progression free at 18 months than the other subtypes.
