six year's assessment of oral and maxillofacial malignancies in patients referred to Vali - Asr Hospital of Zanjan

Despite recent progresses in cancer treatment, the oral cancer is still one of ten most common causes of death because of late diagnosis. Considering the role of cultural and geographical factors in oral cancer prevalence, epidemiological studies are of great importance. Many investigations have reported evidence of an increasing incidence in oral cancers during recent years. The aim of this research was to assess oral and maxillofacial malignancies in patients referring to Vali- Asr Hospital of Zanjan, during six years.

A descriptive and retrospective study was done using 214 medical files of patients whose oral and maxillofacial malignancy was histopothologically confirmed. Necessary demographic clinical and histopathological data were extracted. SPSS software was used to analyze data and drawing table and charts.

Minimum and maximum age of patients were 20 and 89 years respectively. Male to female ratio was 2.16 to 1. The most common clinical feature of oral and maxillofacial malignancies was ulcer and exophytic lesion. The most common site of oral and maxillofacial malignancies lesions were lower lip and tongue.

Although most of epidemiological patterns of oral and maxillofacial malignancies were similar to other researches, but male to female’s ratio and mean age were difference to other studies.
