Abstract

Aurora-A kinase (Aur-A), a member of a family of mitotic serine/threonine kinases, is known to be amplified in epithelial malignancies. In this study, we focused our investigation on Aur-A expression and its prognostic significance in nasopharyngeal carcinoma (NPC). Immunohistochemical staining for Aur-A was performed on the paraffin sections of 208 patients with NPC. Data were subjected to statistical analysis with respect to clinicopathological variables, overall survival and disease-free survival. An immunohistochemical analysis showed that Aur-A was highly expressed in 132 (63.5%) of the 208 NPC tissues examined. Aur-A expression was significantly correlated with T classification (P=0.012), clinical stage (P=0.003) and skull base invasion (P=0.003). Statistical analysis showed that Aur-A expression was inversely correlated with the 10-year overall and disease-free survival rates of NPC patients. Results of the multivariate analysis revealed that Aur-A expression was an independent prognostic indicator for patient survival. More significantly, Aur-A was found to be a marker for poor survival, which was mainly attributed to its high expression in the subgroup of T4 tumor classification with aggressive local invasion. These results indicated that Aur-A expression is inversely correlated with survival and directly correlated with the malignant status of NPC. Therefore, Aur-A may serve as a potential biological marker for poor prognosis in the T4 subgroup of patients.
