title: Clinical presentation of patients with oral squamous cell carcinoma when first seen by dentists or physicians in a teaching hospital in Brazil.
abstract: The ability to diagnose oral cancer depends in part on the knowledge, attitudes, and practices of the health professional. On the other hand, the patients' choice of health professional depends on their perceptions of the ability of such professionals to diagnose and treat what they believe their health problem is. In this study, we investigated the clinical profiles of patients with oral cancer ( n=354) when first seen by dentists ( n=129) or physicians ( n=225) in a teaching hospital. The charts of patients with oral squamous cell carcinoma were analyzed for the following variables: age, sex, race, signs and symptoms by the time of presentation to the health professional, size and site of the tumor since first manifestation, and clinical stage of the disease. Our results demonstrate that dentists and physicians assessed patients comparably regarding age, sex, and race. Patients complaining of dysphagia and odynophagia were seen more often by physicians than dentists (45/225 vs 9/129 [20.0% vs 7.0%] and 30/225 vs 4/129 [13.3% vs 3.1%], respectively), whereas those with local pain and burning preferentially sought dentists (77/129 vs 56/225 [59.7% vs 24.9%] and 4/129 [3.1%] vs 0/225, respectively). Physicians diagnosed oropharyngeal (45/208 vs 9/116 [21.6% vs 7.8%]) and lip lesions (71/208 vs 7/116 [34.1% vs 6.0%]) more often, whereas dentists saw more cases of cancer of the alveolar ridge (42/116 vs 7/208 [36.2% vs 3.4%]) and floor of the mouth (19/116 vs 10/208 [16.4% vs 4.8%]). Our findings suggest that patients have different perceptions of the roles of dentists and physicians regarding the ability to diagnose and treat oral lesions. Signs, symptoms, and location of the cancer lesions appear to be the most important variables associated with the choice of health professional.
