MKI67 and meningioma: In a subgroup of primary meningiomas, EOR (GTR), tumor location (SB), and PTBE (without PTBE), both preoperative NLR (≥ 2.6) and Ki-67 LI were significantly associated with shorter PFS (NLR, P = 0.029, 0.004, 0.013, and 0.034, respectively; Ki-67 LI, P = 0.005, < 0.001, < 0.001, and 0.008, respectively).
