Introduction:
Results from GLOBOCAN 2012 showed that
gastrointestinal cancers including stomach, colorectal,
esophageal and liver cancers are the most common sites
of cancer diagnosed worldwide. Previously Cancer Registry
reports of East Azerbaijan indicated a high incidence of
gastrointestinal cancers in this region, resulted in the
establishment a survey on trend analysis during last decade
in the state.
Material & Methods:
Twelve years cancer registry data of
East Azerbaijan were collected from different sources, and
final data quality check was performed to achieve clean data.
Age-standardized incidence rates were generated using the
2000 WHO standard population, for different cancers for
each solar calendar year, from 1383 to 1394. The annual
percent changes (APC) and average annual percent change
(AAPC) of ASRs for Esophagus, Stomach, Small Intestine,
Colorectal, Anus, Liver, Gallbladder, and pancreas were
calculated with JointPoint 4.3.1.0 software.
Results:
Time trends of different cancers in male and female
showed in Figure. There was an observed increase in all
types of cancers during this time so that ASR for colorectal
cancer increased from 2.97 to 13.62 in female (APC=9.2%,
P<0.001), and 2.32 to 17.82 in male (APC=9.7%, P<0.001).
The ASR for gastric cancer had a slightly increasing trend
from 11.30 to 13.45 in female (APC= 1.2%, P=0.6), and 3.33
to 29.87 in male (APC=2.8%, P=0.3) during last 12 years.
The trend analysis showed a decreasing pattern of ASR for
esophageal cancer with an annual percent change of APC=-
2% in females and APC=-1.2% for males.
Conclusion:
According to the last results of EAPCR data GI
cancers are the most common cancers in East Azerbaijan and
significant increasing trends of ASR was observed for most
of them. These findings demonstrate further population
base epidemiologic interventions for screening and early
detection of most common cancers in this region.
