Abstract
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.
