Abstract

Introduction: In spite of recent advances in cancer treatment, the oral cancer is still one of the top ten causes of death because of late diagnosis and due to various reasons such as being asymptomatic in early stages, similarity of its clinical presentation with other lesions and variety of clinical manifestations. Considering the role of environmental and geographical factors in cancer incidence, epidemiological studies are of great importance. The aim of this study was to determine eight year prevalence of oral and paraoral malignancies of the patients referred to Bou-Ali-Sina hospital as the center of head and neck malignancies in Sari, Iran. Materials & Methods: In this study which was performed on 43 medical files of patients with oral, paraoral and maxillofacial malignancies from March 2005 to March 2013, necessary individual, clinical and histopathological information were extracted. SPSS 18 software was used to analize data and draw tables and charts. Results: Squamous cell carcinoma (SCC) was the most common malignancy (32.2) followed by Basal cell carcinoma (30.2) and Metastatic tumors (6.9). Male to female ratio was 1.5/1 and age average was 55.04±17.56. The most common clinical feature of SCC was exophytic lesion (50), followed by ulcerous lesion (42.8). Basal cell carcinoma mostly appeared with ulcer (62.5) and other malignancies mostly appeared as exophytic lesions (51.1). The most common site of SCC involvement was neck (42.7) while BCC was totally observed on facial skin (100), and the most common site in other malignancies was neck as well (37.5). Conclusion: Most of the epidemiological patterns of oral squamous cell carcinoma were different and less prevalent from other studies. Males had higher incidence rate than females and surprisingly using tobacco had a weak role as a risk factor.
