Abstract

AbstractBackgroundDifferences in pretreatment body mass index (BMI) have been associated with survival in squamous cell carcinoma of head and neck (SCCHN). We examined effects of BMI on survival in SCCHN patients after stratifying patients by tumor human papillomavirus (HPV) status and subsite.MethodsTotally 2204 SCCHN patients in a prospective study were included in this secondary analysis. Multivariable Cox models were used to evaluate associations between pretreatment BMI and overall survival, disease‐specific survival, and disease‐free survival.ResultsBMI was significantly higher among patients with HPV‐positive tumors than HPV‐negative tumors. BMI >25 kg/m2 was associated with improved survival, while BMI <18.5 kg/m2 was associated with reduced survival, particularly in patients with HPV‐positive oropharyngeal cancer tumors.ConclusionsThis exploratory analysis suggests that pretreatment BMI could be an independent prognostic factor of survival outcomes in SCCHN patients, particularly in patients with HPV‐positive oropharyngeal cancer tumors. Further prospective investigations are warranted.
