Prognostic value of the pretreatment albumin:globulin ratio combined with adult comorbidity evaluation 27 and TMN staging in patients with squamous cell carcinoma of the maxillary sinus

Abstract The albumin:globulin (A:G) ratio, adult comorbidity evaluation 27 (ACE-27), and TMN staging have been shown to be strong predictive indicators of the survival of patients with many types of tumours. We have investigated the prognostic value of pretreatment based on the A:G ratio combined with TMN staging and ACE-27 in patients with squamous cell carcinoma (SCC) of the maxillary sinus. We studied 196 patients, and the prognostic value was explored by univariate and multivariate Cox’s hazards analysis. Multivariate analyses suggested that pretreatment A:G ratio was independently associated with overall survival (hazard ratio (HR) 1.542, 95% CI 1.219 to 1.991, p = 0.002); disease-specific survival, (HR 1.499, 95% CI 1.197 to 1.842, p = 0.001); and disease-free survival (HR 1.452, 95% CI 1.207 to 1.834, p
