Abstract:
Background:Whether the ABO blood group is associated with the survival of patients with laryngeal cancer remains unknown. The purpose of this study was to investigate the association between the ABO blood group and clinico?pathologic characteristics of patients with laryngeal cancer and assess whether the ABO blood group was associated with prognosis. Methods:We analyzed the records of 1260 patients with laryngeal cancer who underwent curative treatment at Sun Yat?sen University Cancer Center between January 1993 and December 2009. The Chi?square test was used to assess the relationship between the ABO blood group and clinicopathologic characteristics. The Kaplan–Meier method was used to estimate 3?, 5?, and 10?year overall survival (OS) rates. The Cox proportional hazards model was used in univariate and multivariate analyses of OS. Results:No signiifcant association was found between the ABO blood group and clinicopathologic characteristics except for primary tumor site. The median OS for patients with blood groups A, B, AB, and O were 87.0, 80.0, 90.0, and 72.5months, respectively. The 3?, 5?, and 10?year OS rates were 82.4%, 76.0%, and 67.5% for patients with blood group A; 77.4%, 69.8%, and 58.4% for patients with blood group B; 82.2%, 73.1%, and 65.6% for patients with blood group AB; and 71.7%, 66.4%, and 55.5% for patients with blood group O, respectively. Univariate and multivariate analyses showed that the ABO blood group had signiifcant effects on prognosis in patients with laryngeal cancer. Conclusions:The ABO blood group is associated with survival in patients with laryngeal cancer. Patients with blood group O had signiifcantly shorter OS than patients with other ABO blood groups.
