Squamous cell carcinoma of the head and neck in nonsmokers and nondrinkers: an analysis of clinicopathologic characteristics and treatment outcomes.

Abstract

The objective of this study was to describe the clinicopathologic manifestations of disease and outcomes of treatment among individuals without a history of smoking tobacco or consuming alcohol who develop head and neck cancer. Of 1648 invasive head and neck cancer cases treated between 1970 and 2001 at Roswell Park Cancer Institute, 40 patients were identified as never having smoked tobacco or consumed alcohol during their lifetime. These cases were reviewed to gather data on multiple clinicopathologic variables. Mean age at presentation of nonsmoker/nondrinker head and neck cancer patients was 60 years (range, 27 to 90 years), and 78% (n = 31) of the patients were women. The distributions of tumor sites were 75.0% oral cavity (n = 30), 20.0% oropharynx (n = 8), and 5.0% larynx (n = 2). Sixteen patients (40%) experienced a recurrence of disease during the follow-up period, and 10 patients (25.0%) developed a second primary tumor a median of 6 years after their initial diagnosis. The nonsmoker/nondrinker head and neck cancer patient tends to be elderly and female, have oral cavity primary tumors, and be predisposed to second primary tumor development.
