Morbidity and mortality of oral cancer in Taiwan: Trends from 2000 to 2021.

BACKGROUND/PURPOSE: Oral cancer is a major cause of cancer morbidity and mortality worldwide, especially in Taiwan. This study investigated the morbidity and mortality of oral cancer in Taiwan from 2000 to 2021.

MATERIALS AND METHODS

The population data and the records of cancer registry were obtained from the websites of the Ministry of the Interior and the Ministry of Health and Welfare, respectively. The numbers of oral cancer cases and deaths were analyzed from 2000 to 2021.

RESULTS

The numbers of oral cancer cases and deaths increased from 3378 to 1494 in 2000-8277 in 2020 and 3395 in 2021, respectively. The total increase of oral cancer cases was 4899 with a total increase rate of 145.03%, while the total increase of oral cancer deaths was 1901 with a total increase rate of 127.24%. The changes in the numbers of all cancer cases and deaths, as well as the morbidity and mortality of oral cancer or all cancers also showed similar trends. Furthermore, the death-to-case ratio of oral cancers decreased from 44.23% in 2000 to 40.84% in 2020. The total decrease was 3.39% with a total decrease rate of 7.66%.

CONCLUSION

In Taiwan, people's awareness of oral mucosal health is still inadequate. Obviously, there is still much room for improvement in the oral mucosal health education for our people. With the expertise and responsibility for taking good care of oral health of our people, the dental personnel should take active roles in the prevention and screening for oral cancers.
