ABSTRACT
<p><b>OBJECTIVE</b>To analyze the incidence trends of primary liver cancer (PLC) in Qidong.</p><p><b>METHODS</b>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.</p><p><b>RESULTS</b>Significant moderation or decreasing trends were began to notice in incidence rates on cohorts born in 1913 - 1917 and 1958 - 1962.</p><p><b>CONCLUSION</b>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.</p>
