Abstract:
The incidence of oral cancer is differed in the world. Oral cancer incidence was high in Melanesia, South-Central Asia, East and Central European countries,3 while it was likely to be low in Africa, East Asia, and Central American countries.
Our study purpose was to determine the risk factor of tongue cancer and to study between correlation T, N stage and type of tongue cancer.
The study was carried out by retrospective method, by using the medical reports obtained from the National Cancer Center of Mongolia.
This study, based on retrospective method was conducted from medical reports of 68 patients who were diagnosed with squamous cell carcinoma of the tongue and at the Department of Head and Neck Surgery, Radio and Chemotherapy of the National Cancer Center of Mongolia between 2005 and 2014.
The data was analyzed using SPSS 20.0 software; descriptive and detailed statistical analysis was made. Assumptions were examined by H2 testing method; it shall be statistically significant when P value is less than 0,05.
The median age of the 68 patients at diagnosis was 58 years (range=31-85 years) and were 57% (39) men, 43% (29) women with a male to female ratio of 1.3:1.
Of 37 patients who were tobacco users 66.7% (26) were male, 37.9% (11) were female, among the alcohol consumers (35.9% (14) were male, 10.3% (3) female). This difference between male and female consumption was significantly different according to the test Pearson p=0.019 for tobacco, p=0.016 for alcohol.
There was trend toward more higher N stages in endophytic tumors, with 69.3%, in ulcerative tumors, with 66.7% of these cases presenting with nodel involvement, 45% of patients with exophytic tumors.
Our study showed that oral tongue cancer in majority occur in fifth and sixth of life and with a male predominance. Smoking and drinking alcohols are two major risk factors for SCC of tongue cancer. Although not significant, it has been suggested that endophytic tumors have a higher propensity to metastasize to cervical lymph nodes than exophytic tumors.
