SIX YEAR’S ASSESSMENT OF ORAL AND MAXILLOFACIAL MALIGNANCIES IN PATIENTS REFERRING 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 ValiAsr Hospital of Zanjan, during six years.
Materials & Methods: 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.
Results: 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.
Conclusion: 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
