Conclusion: The age-adjusted Charlson comorbidity index (ACCI) was associated with overall survival, disease-specific survival, and non-cancer death in patients treated with chemoradiation therapy (CRT) for hypopharyngeal cancer (HPC). Further studies using other CRT regimens are required. Objective: To investigate the impact of the ACCI on survival in patients with HPC. Methods: This study reviewed 128 patients with HPC who received CRT between 2004–2012. The survival rates and the cumulative incidence of non-cancer death according to the ACCI were estimated. A Cox proportional hazard model was used to assess the hazard ratio (HR) of the ACCI. Results: The disease-specific survival rates at 3 years for the low ACCI group, moderate group, and high group were 80.1%, 45.8%, and 54.8%, respectively (p = 0.007). The laryngectomy-free survival rates at 3 years were 61%, 39.7%, and 37.1%, respectively (p = 0.137). The cumulative incidences of non-HPC death were 5% for the low/moderate ACCI group and 15.5% for the high ACCI group (p = 0.031). The HRs compared to the low ACCI group for overall survival, disease-specific survival, and laryngectomy-free survival were 2.61 and 2.74, 2.55 and 2.27, and 1.75 and 1.97 in the moderate and high ACCI groups, respectively.

Various serum biomarkers have been developed for predicting head and neck squamous cell carcinoma (HNSCC) prognosis. However, none of them have been proven to be clinically significant. A recent study reported that the ratio of aspartate aminotransaminase (AST) to alanine aminotransaminase (ALT) had a prognostic effect on non-metastatic cancers. This study aimed to examine the effect of the AST/ALT ratio on the survival of patients with HNSCC. Clinical data of 356 patients with locoregionally advanced HNSCC were collected. The effect of the AST/ALT ratio on overall survival was analyzed using a Cox proportional hazard model. Moreover, recursive partitioning analysis (RPA) was used to divide the patients into groups on the basis of the clinical stage and AST/ALT ratio. The prognostic ability of this grouping was validated using an independent data set (N = 167). The AST/ALT ratio ranged from 0.42 to 4.30 (median, 1.42) and was a prognostic factor for overall survival that was independent of age, primary sites, and tumor stage (hazard ratio: 1.36, confidence interval: 1.08−1.68, P = 0.010). RPA divided patients with stage IVA into the following two subgroups: high AST/ALT (≥2.3) and low AST/ALT (<2.3) subgroups. The 5-year survival rate for patients with stage III, stage IVA with a low AST/ALT ratio, stage IVA with a high AST/ALT ratio, and stage IVB were 64.8%, 49.2%, 28.6%, and 33.3%, respectively (p < 0.001). Compared with the low AST/ALT group, the adjusted hazard ratio for death was 2.17 for high AST/ALT group (confidence interval: 1.02–.22 P = 0.045). The AST/ALT ratio was demonstrated to be a prognostic factor of HNSCC. The ratio subdivided patients with stage IVA into low- and high-risk groups. Moreover, intensified treatment for the high-risk group may be considered. [ABSTRACT FROM AUTHOR]

Conclusions: Comorbidities as well as T classification were the primary determinants for the nutritional status of patients with head and neck cancer. Objectives: We aimed to elucidate the underlying conditions of malnutrition in patients with head and neck cancer. Methods: We retrospectively reviewed 726 patients diagnosed with head and neck cancer between 2004 and 2013. Associations between malnutrition and clinical parameters were assessed using univariate and multivariate analyses. Results: Median body mass index was 21.5 (range 11.6-38.0). According to World Health Organization criteria, the nutritional status of these patients was classified into four groups: underweight (18%), normal (63%), overweight (17%), and obese (1%). Comorbidities were detected in 40% of patients. Multivariate analysis revealed the following factors to be independent factors associated with malnutrition: advanced T stage, metachronous cancer, collagen disease, gastrointestinal disease, and pulmonary disease.
