Abstract
OBJECTIVES: Most patients with oral cancer lack early symptoms, therefore most present with advanced stage of disease. Early detection of oral cancer and oral potentially malignant disorders (OPMDs) in the asymptomatic phase via an opportunistic oral cancer screening examination is important as survival rates are significantly improved if the disease is treated at an earlier stage. The objective is to identify opportunities to achieve early stage diagnosis of oral cancer in Australian patients. MATERIALS AND METHODS: A cohort of 103 patients newly diagnosed with oral cancer were surveyed at a tertiary hospital Head and Neck Clinic. Patient awareness, knowledge, risk factors and diagnostic delay in oral cancer diagnosis were investigated. The asymptomatic period before diagnosis was studied to identify opportunities for improving opportunistic screening rates in Australia. RESULTS: Australian patients have poor awareness of oral cancer with 46% having never heard of oral cancer, and poor knowledge of risk factors for oral cancer. Only 7% were diagnosed in the asymptomatic phase and all by dental practitioners. Once symptomatic, median diagnostic delay was 9 weeks. In the asymptomatic phase before diagnosis, patients attended general medical practitioners far more often than general dental practitioners. Both groups rarely discussed risk factors for oral cancer (<10%) or performed opportunistic oral cancer screening examinations (<10%) with their patients. CONCLUSION: Asymptomatic diagnosis of oral cancer at an earlier stage of disease is possible in the primary medical setting but increased awareness and knowledge are required in both patients and health practitioners.
