Incidence rates and trends for oral and pharyngeal cancer in North Carolina: 1990-1999.
This study describes the incidence of oral and pharyngeal cancer (OPC) in North Carolina (NC) from 1990 to 1999. OPC cases 1990-1999 from the NC Central Cancer Registry were included. Variables included date of diagnosis, county of residence, anatomical site, histology, age at diagnosis, sex, race, stage at diagnosis, grade, tumor behavior, and laterality. The overall average annual rate of OPC was 10.6 cases per 100,000 population. OPC incidence was highest for African-American males and for eastern NC; there was no significant trend in the overall annual incidence rate. Squamous cell carcinoma of the lip increased for white females and other oral cancers decreased among all females. With a few specific exceptions, NCCCR rates were similar to SEER rates. North Carolina continues to have substantial OPC incidence and substantial racial disparities persist.
