한국인에서 구강 편평세포암의 발생 연령과 부위에 대한 연구 Investigation on the Age and Location of Oral Squamous Cell Carcinoma Incidence in Korea
pp.393-402
Many researchers have been reported recent trends for rising incidence particularly related to cancer of the tongue in young people. The purpose of this study is to exam the changes of OSCC(oral squamous cell carcinoma) incidence distribution. After Institutional Review Board approval, 1,345cases of OSCC were reviewed from 1993 to 2012 at the department of Oral Pathology at the University of Seoul National Dental Hospital with respect to gender, age, locations. As the results, the most prevalence ages were between 45-69 years old(mean:59.68). There is a noticeable incidence on the eighth decade of life. There are no changes of incidence distribution on se (male:female=69:31) at each year. The most common incidence area was tongue at 1993 but the mandible was the most popular site after 2001. Comparing the incidence rates of the predilection sites over and under 44 years old patients, among patients under 44 years old showed the tongue is the common site steadily. On the other hand, there is a significant increase on the mandible in the over 44 years old patients. In conclusion, this study showed similar results on overall sex distribution and median ages. The trends of locations over 20 years have been increased on the old adult’s mandible. Also, tongue is the common site for the young adults constantly. There are needs for further studies to elucidate the behind etiology. In addition, the true impact of young age on OSCC clinical behavior will remain difficult to determine unless intranational and multi-institutional databases will be combined.
