Abstract

Abstract: PURPOSE : To analyze the incidence of oral malignancies in Shanghai from 2003 to 2012 and to study its time trend, for the purpose of searching for the clues of etiology. METHODS : Based on the incidence data of oral malignancies registered in Shanghai Municipal Center for Disease Control & Prevention, the incidence rate, sex ratio and age distribution were calculated by Excel and SPSS 17.0 software package. The time trend of the incidence of oral malignancies were studied by APC (annual percent change) model, Z-test and Cochran test. RESULTS : A total of 4935 oral malignancy cases were newly diagnosed from 2003 to 2012 in Shanghai. The crude incidence was 35.8 per 1 000 000 and the age-adjusted incidence was 18.8 per 1 000 000. The male/female ratio was 1.36:1 with the median age of 63. The average age of women was greater than man. The risk of oral malignancy increased with aging. During the 10 years' time, the crude incidence of oral malignancies in Shanghai showed an increasing trend. CONCLUSION S: With the progress of city aging trend in Shanghai, the incidence of oral malignancies was increasing. More attentions should be paid to the senile population for oral malignancies.
