Background: This study examines the epidemiological trends of oropharyngeal squamous cell carcinoma (OPSCC) and oral cavity squamous cell carcinoma (OCSCC) in Northern New England.
Methods: Data were obtained from the Maine, New Hampshire and Vermont cancer registries. The age-standardized incidence rates (ASIR), age-specific incidence rates, and annual percentage changes (APC) for OPSCC and OCSCC were calculated using Joinpoint regression.
