| Abstract | {Aim: Survivin is a member of the inhibitors of apoptosis (IAP) gene family that acts through pathways different from those involving the bcl-2 family. Largely undetectable in normal adult tissues, survivin is deregulated in most human cancers including non-small-cell lung cancer (NSCLC) and may represent a tumor marker with prognostic and therapeutic implications. Aim of our study was to determine the prognostic role of survivin as an apoptosis-related biomarker in a series of resected NSCLC patients. Methods: A retrospective series of resected NSCLC patients were retrieved from the files of the Regina Elena National Cancer Institute. Survivin was detected by immunohistochemistry (IHC) using a polyclonal antibody. Survivin displayed two kinds of immunoreactivity: (i) a diffuse cytoplasmic staining and (ii) a distinct nuclear staining. A score-scale to distinguish positive (score 1-2) vs. negative (score 0) pattern was applied. Clinical and biological (nuclear and cytoplasmic survivin staining) covariables were screened for a prognostic relationship with overall survival (OS) and disease-free survival (DFS) into the univariate and multivariate analyses. Results: Data referring to 116 NSCLC patients who underwent surgery for stage I-IIIA NSCLC were collected. Multivariate analyses identified tumor size, nodal status and nuclear, but not cytoplasmic, expression of survivin as significant independent predictors of OS, with a hazard ratio of 2.40 (95% CI 1.44, 3.99 |
