Liver cancer differentials in immigrant and local-born Chinese in Singapore

Abstract

A total of 99 liver cancer cases and 1044 hospital controls drawn from Chinese residents of Singapore were interviewed between March 1966 and August 1968 with respect to country of birth, duration of stay in Singapore, province of birth in China and specific community (dialect group). The results show a significantly higher risk of liver cancer among immigrant Chinese than among the local-born. However, the higher relative risk among China-born Chinese in this study was much less than found previously in surveys of liver cancer cases necropsied in Singapore between 1950 and 1959. No relationship was found between liver cancer and province of birth in China, duration of residence in Singapore, or dialect group. © 1970.
