Abstract: Objective To identify the expression of Aurora-A and its correlation with cisplatin resistance and prognosis in non-small cell lung cancer(NSCLC).Methods A total of 62 NSCLC patients treated by surgery and adjuvant cisplatin-based chemotherapy were included in our study.The expression of Aurora-A was determined by immunohistochemical(IHC)analysis.Correlation between Aurora-A expression and clinic pathological variables was estimated.The prognostic significances were assessed by Kaplan-Meier method,and the differences in survival probabilities were evaluated by the Log-rank test.Results IHC showed that 26 out of the 62 NSCLC patients were with high Aurora-A.There was no significant association between Aurora-A expression and clinic pathological variables.The overall survival of patients with high Aurora-A expression(median survival time:50.1 months)was significantly poorer than those with low Aurora-A expression(median survival time:55.8 months).Conclusion The present study suggests that high Aurora-A expression is correlated with cisplatin-based chemotherapeutic resistance and predicts poor patient survival in NSCLC.However,further in vitro study is needed.
