Diagnostic intervals in oropharyngeal cancers from a primary care perspective: a ten-year case note review.

Background Rates of oropharyngeal (OP) cancer are increasing and mortality is related to stage at diagnosis. Early diagnosis is vital to improving patient outcomes.Aim To describe current general practice pathways and time intervals in OP cancer and: a) compare to current National Institute for Health and Care Excellence guidance to refer from general practitioners (GPs) to general medical dentists (dentists); and b) referral pathways for pharyngeal cancers.Design and setting A ten-year retrospective study of patients diagnosed with OP cancer in one suburban general practice in England using GP notes, including secondary care correspondence.Results There were 12 cases of OP cancer; six oral and six pharyngeal. There were marked differences in referral pathways and time intervals for people with visible, or palpable, oral cancers and those with non-visible, or impalpable, pharyngeal cancers. No one had GP to dentist referral. General practice 'safety-netting' or follow-up was not commonly recorded.Conclusion GPs are pivotal in diagnosing symptomatic OP cancers. General practice and dental teams encountering symptoms of uncertain aetiology (for example, pharyngitis) should offer safety-netting to shorten patient intervals to re-attendance. Pathways for oral cancer referral were usually clear and linear. Pathways for pharyngeal cancer were usually complex, with much longer time intervals in primary and secondary care, and would benefit from a single national referral pathway to ENT.
