Squamous cell carcinoma of the upper aerodigestive tract in patients 40 years of age and younger.
Oral squamous cell carcinoma in patients 40 years of age and younger has been noted to be infrequent. The incidence is not as noticeable because the majority of oral cancers are diagnosed during the later decades of life. This study was undertaken to evaluate the incidence, site predilection, etiologic factors, and modes of treatment and to compare these results with available data on this topic. Of 1387 cases of oral and pharyngeal squamous cell carcinoma diagnosed from 1968 to 1989 at University Hospital and affiliated institutions, 28 occurred in patients under 40 years of age. When these lesions were staged according to the American Joint Committee for Cancer Staging, we found 6 stage I lesions, 3 stage II, 2 stage III, and 11 stage IV. Six lesions could not be staged from information available in the patient records. Present data corroborate the national average of 1% to 3% of cases of oral squamous cell carcinoma found within the 40 and under age group.
