Prognostic impact of stathmin 1 expression in patients with lung adenocarcinoma

Abstract Objective Stathmin 1 is a major cytosolic phosphoprotein that regulates microtubule dynamics and is associated with malignant phenotypes in various cancers, including non–small cell lung cancer. We aimed to determine differences in overall survival and disease-free proportion in patients wi...

Zusammenfassung:Abstract Objective Stathmin 1 is a major cytosolic phosphoprotein that regulates microtubule dynamics and is associated with malignant phenotypes in various cancers, including non–small cell lung cancer. We aimed to determine differences in overall survival and disease-free proportion in patients with lung adenocarcinoma stratified by stathmin 1 tumor expression. Methods With the use of immunohistochemistry, stathmin 1 expression was determined in resection specimens from 303 patients with adenocarcinoma. Associations between stathmin 1 protein expression and overall and disease-free proportion were assessed (Kaplan–Meier survival curves compared with log-rank statistics). Cox proportional hazards regression determined the hazard for death stratified by stathmin 1, adjusting for clinicopathologic characteristics. Results During follow-up, 74 (24.4%) recurrences and 73 (24.1%) all-cause deaths were recorded. Expressed in 53.8% of adenocarcinoma cases, overall survival and disease-free proportion were significantly worse in stathmin 1–positive patients (log-rank P
