Multivariate analyses with adjustment for FIGO stage and postoperative residual tumor revealed that neutrophil elastase was an independent poor prognostic marker for OS (adjusted HR, 10.17; 95% CI, 1.09−94.97; P = 0.042) (Table 2) and PFS (adjusted HR, 14.47; 95% CI, 1.52−137.35; P = 0.020) (Supplementary Table 3). This evidence concerns the gene ELANE and neoplasm.
