Squamous Cell Carcinoma in Older Patients without Risk Factors

Ten patients over sixty years of age with no history of tobacco or alcohol use were treated for squamous cell carcinoma of the upper aerodigestive tract between 1979 and 1991. Nine of these ten patients were women with lesions confined to the oral cavity and oropharynx. Modes of treatment included surgery, radiation, or a combination of surgery and radiation. Followup from 1 to 10 years revealed two deaths from local and distant spread, and eight patients with no evidence of disease. Recurrences after treatment were aggressive and occurred within the same region as the primary lesion. Although most patients with upper aerodigestive squamous cell carcinoma are men with alcohol and/or tobacco exposure, this study demonstrates findings consistent with field cancerization in a group of older women with no risk factors.
