The impact of routine CT of the chest on the diagnosis and management of newly diagnosed squamous cell carcinoma of the head and neck.

Abstract

A relatively large percentage of patients (19%) with newly diagnosed squamous cell cancer of the head and neck was found to have additional malignant tumors, 32% of which were synchronous primary tumors. The discovery of these additional neoplasms had a major effect on both the therapy and the prognosis of these patients. The combination of a relatively poor detection rate for conventional chest radiography, with only 29% of the malignant tumors detected on CT scans of the chest being seen on chest radiographs, and the high prevalence of disease in this population support the routine inclusion of thoracic CT in these patients.
