title: Cancer of the ear: a report of 22 patients.
abstract: The purpose of this report was to analyze cancer of the ear, with reference to its etiology, pathology and classification, by studying 22 patients who visited Kitasato University Hospital over a 26-year period. Patients with cancer of the ear comprised 0.98% of the 2,244 registered head and neck patients. Classifications reported in the literature were utilized to analyze the patient data. There was a significant difference in 5-year cumulative survival rates associated with cancers arising from the external auditory canal and the middle ear, as calculated using the Kaplan-Meier method. Tumor stage was also a significant predictor of prognosis. If cancer is suspected, early diagnosis is the key to improved prognosis.
