Finally, survival analysis including therapy-naïve, completely resected meningioma patients only revealed that upregulated expression of 5 of these genes (PTTG1, UBE2C, COX10, ECT2, and PRC1) as well as downregulation of LEPR and MN1 was associated with a significantly reduced progression-free survival time. This evidence concerns the gene PTTG1 and meningioma.
