[The trends on the mortality for esophagus and stomach cancers in Linzhou city from 1988 to 2003].
OBJECTIVE
Using the data on death for esophagus and stomach cancers in Linzhou cancer registration system, the mortality was described as well as the changing trend was analyzed.


METHODS
18 240 death recorders for the both cancers during 1988 to 2003 were drawn from Linzhou cancer registration system. Of which, 10138 cases were esophageal cancer and 8102 cases were gastric cancer. Then data were stratified by sex, age, year and then linked to demographic classifications. The mortalities of two topographic site cancers were calculated and the age-adjusted rates were calculated by direct standardization to the world population. The Joinpoint model was used to get the estimated annual percent change (EAPC) of the age-adjusted rates, so to estimate the death rate change trends of both cancers in population of Linzhou city.


RESULTS
In 2003, the age-adjusted mortalities of esophageal cancer and gastric cancer were 68.47 per 100,000 and 57.01 per 100,000 respectively of Linzhou city. From 1988 to 2003 the death rates for both of cancers had showed the decline trends. The EAPC of the mortality for esophageal cancer was -3.82 (-4.81 - -2.82, P < 0.001) and that for gastric cancer was -2.95 (-4.16 - -1.73, P < 0.001) respectively.


CONCLUSIONS
The declining trend in was observed the mortality of esophageal and gastric cancer in Linzhou by this study.
