Abstract:Objective To evaluate the clinical features of local advanced glottic laryngeal cancer patients with beyond five years survival and to provide help for the treatment of advanced glottic laryngeal cancer patients. Methods The data of 129 cases of patients with local advanced glottic laryngeal cancer treated in our hospital from January 1991 to August 2005 were analyzed retrospectively. They were divided into two groups based on their survival time. Forty six patients with beyond five years survival were included in the first group and the other eighty three patients were in the second group. The clinical features were compared and factors associated with survival were identified. Results Compared with the group with under five years survival, the lymph node metastatic rate before treatment was lower, patients treated concurrently with operation were more, and complete remission rate after treatment were higher in the group with beyond five years survival. The differences between two groups had statistical significant.Cox regression analysis identified only operation and complete remission rate were independent prognostic factors. Conclusion For local advanced glottic laryngeal cancer，rational comprehensive treatment and complete remission after treatment and complications prevention are important. But they need to be validated by the large-scale clinical trials.
