Comorbid conditions have a significant impact on the actuarial survival of patients with head and neck cancer. However, no studies have evaluated the impact of comorbidity on tumor- and treatment-specific outcomes. This study was performed to evaluate the impact of comorbidity, graded by the Kaplan-Feinstein comorbidity index (KFI) on the incidence and severity of complications, disease-free interval, and tumor-specific survival in patients undergoing curative treatment for head and neck cancer.
