Abstract
- <bold>Background: </bold>The present study was designed to specifically investigate the clinicopathological role of expression of cortactin, as well as the correlation with clinical outcomes in stages II-III colorectal cancer (CRC).<bold>Methods: </bold>Two hundred and five stages II-III CRC patients were included in this study. Formalin-fixed paraffin-embedded specimens were stained for cortactin and the correlation between the staining, its clinicopathological parameters, and its prognostic power were analyzed statistically.<bold>Results: </bold>Of the 205 patients studied, 113 cases (55.1%) were strongly positive for cortactin. Cortactin expression correlated with tumor invasion (P = 0.018), histological grade (P = 0.004), and preoperative CEA level (P < 0.001). In univariate analysis, tumor invasion, American Joint Committee on Cancer (AJCC) stage, lymphovascular invasion, preoperative CEA level, and cortactin expression were significant prognostic factors for disease-free survival (P = 0.034, 0.009, 0.043, 0.004, and 0.004, respectively), while for overall survival, tumor invasion, AJCC stage, pathologic grade, preoperative CEA level, and cortactin expression were significant prognostic factors (P = 0.003, 0.008, 0.038, 0.017, and <0.001, respectively). In multivariate analysis, tumor invasion, preoperative CEA level, and cortactin expression maintained their independent prognostic influence on disease-free survival (P = <0.001, 0.003, and 0.008, respectively). However, tumor invasion, AJCC stage, and cortactin expression influenced overall survival (P = 0.036, <0.001, and 0.004, respectively).<bold>Conclusions: </bold>Cortactin may be a good biomarker to be applied in the clinical setting to predict the prognosis of patients with completely resected pathologic stages II-III CRC.
