The results of this study show that comorbidity is an important feature of patients with head and neck cancer. Valid instruments exist to measure and classify the overall severity of comorbidity. The scientific evaluation of treatment and the care of patients are impeded by a rigid adherence to a staging system based solely on morphological descriptions of the cancer while ignoring suitable descriptions of the patient. The author believes that the addition of comorbidity information will improve the value of cancer statistics and the care of cancer patients.
