title: An audit of the UK national cancer referral guidelines for suspected oral mucosal malignancy.
abstract: OBJECTIVE
  This study aimed to assess the effectiveness of the UK National Guidelines for identifying patients with potentially malignant oral disease which were introduced in 2000.
  
  
  METHODS
  Retrospective audit.
  
  
  METHODS
  The oral medicine unit in a university teaching hospital in London.
  
  
  METHODS
  All new referrals over a one year period were retrospectively reviewed in a departmental audit to evaluate guideline effectiveness. Reasons for referral and final diagnosis were compared in a randomly selected sub-population.
  
  
  RESULTS
  Four hundred and eighty-seven of 901 new patients referred were classified as having potentially malignant disease from the referral letter. In a randomly selected subgroup of 241 patients, 18 actually had malignant (8) or dysplastic lesions (10). Of 75 patients referred with a persistent oral ulcer, only nine were actually malignant or dysplastic. Eight of 116 patients referred with a white patch and none with red patches were found to have dysplastic or malignant lesions. The criteria failed to identify three carcinomas and two severely dysplastic lesions (15% of the malignant or dysplastic lesions). All of the latter had been referred by primary care physicians with orofacial pain of unknown cause.
  
  
  CONCLUSIONS
  UK National Guidelines discriminate poorly between potentially malignant and other oral mucosal disease.
