A 50 years' single - center analysis of epidemiologic characteristics of oral cancer in Guangdong Province

To study the epidemiological characteristics of oral cancer and the pattern of the onset of oral cancer, in order to provide references for preventing and monitoring the development of oral cancer.

The information of 4097 oral cancer patients who came from Guangdong province treated in the Sun Yat-Sen University Cancer center from 1960 to 2013 was retrospectively analyzed. SPSS 21.0 was used for the statistical analyses.

The male-to-female ratio among oral cancer patients was approximately 2:1 and this ratio decreased over time. Oral cancer mostly occurred in patients between 45 to 64 years, and the percentage of elderly patients gradually increased over time. The most common location was the tongue especially lateral tongue. The pathological type of oral cancer was mainly squamous cell carcinoma. The percentage of O blood type in oral cancer patients was significantly lower than that in the normal population. The male-to-female ratio in the Chaoshan area was higher than that in the Guangfu area and the Hakka area, whereas the age of disease onset in the Guangfu area was higher than that in the Hakka and Chaoshan areas. The male-to-female ratio was lower and the age of disease onset was higher in the Pearl River Delta region than in the non-Pearl River Delta region.

During the process of screening for oral cancer, more attention should be paid to the middle-aged and elderly, males, and non-O blood type individuals. In addition, propaganda should be strengthened to encourage residents to change bad living habits.
