-A "registry" of all known cases of nasopharyngeal carcinoma in
Malaysia, 1968-72, was established. Attention was focused on the State of Selangor
where conditions are best for case finding. Age-adjusted incidence rates among
Chinese males and females were 17-3 and 7-3 per 100,000; among Malay males and
females, the rates were 2-5 and 0-3 and among Indian males, 1-1. The detailed
ethnicity of 1,92 cases in Selangor was established. Estimated incidence rates for
the Chinese stib-groups agreed with the pattern observed elsewhere: highest among
the Cantonese, lowest among the Hokkien/Teochiu, with the Khek in between. There
was no correlation between histological type and sub-ethnic group among the
Chinese cases.
