Oral and tongue cancer rates rise among young Americans
3/3/2002 Palm Desert American Head and Neck Society A new research study asserts that even though the overall incidence of head and neck cancers has remained stable, young Americans are being diagnosed with higher rates of oral and tongue cancer. The goal of the research was to update and confirm the changes in incidence of young adult oral tongue cancer, as well as other head and neck cancers, using a large cancer surveillance database in the United States. A unique feature of the analysis was to describe incidence trends by use of a new statistical methodology, joinpoint regression, and to establish the statistical significance of changes in disease rate. Methodology: Data for the analysis were obtained from the Surveillance, Epidemiology, and End Results Program Public-Use CD-ROM (1973-1997), National Cancer Institute, DCCPS, Cancer Surveillance Research Program, Cancer Statistics Branch, released April 2000. Information was obtained on all cancers occurring in residents from nine population-based registries, i.e., five states (Connecticut, Hawaii, Iowa, New Mexico, and Utah) and four standard metropolitan statistical areas (Atlanta, Detroit, San Francisco-Oakland, and Seattle-Puget Sound). The studied cities encompass 10 percent of the U.S. population. The SEER Program used the International Classification of Diseases for Oncology to code site, histology, and behavior for all cancers. The study only included invasive tongue cancer cases Incidence rates were tabulated as per 100,000 population and age-adjusted by the direct method to the 1970 U.S. standard population. Rates for three age groups (<40 years, 40-64 years, and >=65 years) age-adjusted within these [...]
