Yw. Wang et al., IS NASOPHARYNGEAL CARCINOMA MORE COMMON IN HAKKAS THAN IN FUKIENESE -A COMPARISON WITHIN THE TAIWANESE POPULATION, Oncology Reports, 2(3), 1995, pp. 431-434
This study is to ascertain whether Hakkas have a higher incidence of n
asopharyngeal carcinoma (NPC) than Fukienese as being proposed. A tota
l of 949 NPC patients during 1990-1993 were serially recruited. Their
ethnicity and residential area since childhood were compared to the ce
nsus data in 1956. The 95% confidence interval of odds ratios for Hakk
as to Fukienese in various counties were found to overlap within a ran
ge from 0.85 to 1.15 without showing statistically significant differe
nce from unity. This result indicates that there is no extra ethnic ri
sk between the two groups in Taiwan.
