Our multivariate survival analyses adjusted for WHO grade and extent of resection, indicated the independent prognostic significance of high PD-L1 and NFKB2 co-expression to predict tumor progression (p = 0.002, HR = 1.57,CI(95%) = 1.117–2.11) (Supplemental Table 2). The gene discussed is NFKB2; the disease is neoplasm.
