Nasopharyngeal Carcinoma: Knowledge amongst General Practitioners in Western Sydney

Fernandes B, Cherrett C, Moryosef L, Lau N, Wykes J

Background: The west of Sydney has a high population of Asian descent, a high risk population to nasopharyngeal carcinoma (NPC). There is a lack of primary research focused on evaluating the clinical knowledge amongst primary health providers in managing this presentation.

Method: A cross-sectional study, involving surveying 113 General Practitioner (GP) practices in the Fairfield and Bankstown city region on clinical knowledge around key aspects of epidemiology, aetiology, clinical presentation and management of Nasopharyngeal Carcinoma. 42 surveys were completed.

Results: GPs were well aware of many NPC symptoms, with over 90% recognizing epistaxis, nasal obstruction and cervical lymphadenopathy. Many GPs were aware of several aetiological factors for NPC, in particular smoking (95.2%), however a significant proportion were not aware that Epstein-Barr Virus (EBV), pre-existing Ear Nose & Throat (ENT) disease, and formaldehyde exposure were key risk factors (60%). All participants judged CT, MRI and specialist referral as useful management options but a significant proportion (29.7%) would chose to refer between 2-4 weeks from presentation outside the critical 2 weeks’ time frame. Nearly half of the GPs surveyed (45.2%) believed that they had insufficient knowledge of NPC and required further information (81%).

Conclusion: GPs in the west of Sydney would benefit from further education in order to improve the diagnosis and management of these patients.
