[Cancer mortality analysis among aborigines in Taiwan].
Mortality among Aborigines tribes in Taiwan from malignant neoplasms in the 1971-80 and 1981-90 decades were analyzed. Sex and tribe specific standardized mortality ratios were calculated from death certificate data and compared with the number of expected deaths derived from the cancer mortality of the entire population of Taiwan. Mortality due to oral cancer was statistically significantly higher than expected among Paiwan men in the 1971-80 decade and among Paiwan women from 1971-80 and 1981-90; as was mortality from nasopharyngeal cancer among Bunun, Paiwan and Rukai men from 1981-90 and among Bunun and Paiwan women from 1971-80 and 1981-90; mortality due to stomach cancer among the Atayal, Bunun and Paiwan people from 1971-80 and 1981-90, among Rukai men from 1971-80 and among the Tsou and mixed group women from 1981-90; mortality from liver cancer among Atayal and Bunun men in 1971-80, among Bunun women from 1971-80 and 1981-90 and among Paiwan women in 1981-90; mortality due to nasal cavity, middle ear and paranasal sinuses cancer among Rukai men from 1981-90; and mortality due to bone cancer among Tsou men and Atayal women from 1981-90. Mortality due to colorectal cancer was statistically significantly lower than expected among mixed group men from 1971-80 and in Atayal women from 1981-90; as was mortality from lung cancer among Atayal men and Paiwan women from 1971-80 and among Paiwan and mixed group men in the 1981-90 decade. Overall, the standardized mortality ratio of all cancers in aborigines was a little higher than in the general population of Taiwan. However, differences for ratio or site existed in different tribes.
