OBJECTIVESThis scoping review provides a comprehensive overview of oral cavity cancer (OCC) and oropharyngeal cancer (OPC) in Alberta. METHODSA database search was conducted up to 2018 using Web of Science, Scopus, Medline, PubMed and Embase, along with a manual search of gray literature. Data from the Alberta Cancer Foundation's dedicated fund for research, Cancer Surveillance and Reporting and Alberta Cancer Registry were also collected. RESULTSOur review included 8 published papers and 14 other sources, including data on 3448 OCC and OPC patients from Surveillance and Reporting and Alberta Cancer Registry. Cancer registry data (2005-2017) showed that most OCC and OPC lesions were diagnosed at an advanced clinical stage, with a significantly large number of advanced OPC lesions in stage IV (OCC 45.2%, OPC 82.4%); 47.9% of these patients died. Survival rates were lowest in rural and First Nations areas. In Alberta, 35% of HPV-associated cancers were linked to OPCs, which were more prevalent in men and younger age groups. No routine public oral cancer screening program currently exists in Alberta. General practitioners and dentists refer patients to specialists, often with long waiting times. CONCLUSIONOCC and OPC patients in Alberta continue to be diagnosed in stage IV and experience high mortality rates.
