The Analysis Of The Prognostic Factors Affecting The Survival Rate Of Laryngeal Carcinoma

Purpose:To investigate the factors affecting the survival rate of laryngeal carcinoma.Methods:Seventy-seven cases were analyzed retrospectively,including sex, age smoking,race,primary site.pathological grade,T-stage,N-stage,clinical stage, treatment methods.Survival analysis was performed by Kaplan-Meier method; comparison among/between groups was performed using log rank test;multivariate analysis was carried out using Cox proportional hazard model.Results:Overall 1-,3-and 5- year survival rates were 98.7%,73.4%and 54.1%.Univariate analysis showed that primary site,pathological grade,T-stage,N-stage,clinical stage and treatment methods were proven to significant(P＜0.05).Multivariate analysis showed the prognosis statistically correlated with primary site(P＜0.046),pathological grade(P＜0.027),clinical stage(P＜0.030)and treatment methods(P＜0.009).Conclusion:The factors affecting the prognosis of the patients with laryngeal carcinoma are primary site,pathological type, T-stage,N-stage,clinical stage and treatment methods;the independent prognostic factors are primary site,pathological type,clinical stage and treatment methods.
