To analyze the incidence trends of primary liver cancer (PLC) in Qidong. Data of PLC incidence from 1975 to 1999 in Qidong were analyzed to delineate temporal trends and birth cohort patterns, using age-period-cohort models. Significant moderation or decreasing trends were began to notice in incidence rates on cohorts born in 1913 - 1917 and 1958 - 1962. Results showed that the incidence risk of the birth cohorts after 1958 - 1962 started to decline. The changes were possibly associated with the implementation of some practical measures on prevention.
