BACKGROUND: @entity1778 accounts for 8% of total @entity5 cases and involves all age groups with different prevalence and incidence rates in Iran and the entire world and causes a significant death toll and heavy expenses for diagnosis and treatment processes. This study was done to evaluate epidemiology and morphology of @entity5 during 2003-2008. MATERIALS AND METHODS: This cross- sectional study was carried out based on re- analysis of the Cancer Registry Center report of the Health Deputy in Iran during a 6-year period (2003 - 2008). Statistical analysis for incidence time trends and morphology change percentage was performed with joinpoint regression analysis using the software Joinpoint Regression Program. RESULTS: During the studied years a total of 18,353 @entity5 were recorded. Chi square test showed significant difference between sex and morphological types of @entity5 (P-value<0.001). Joinpoint analysis showed a significant increasing trend for the adjusted standard incidence rate (ASIR) for both sexes (P-value<0.05). Annual percent changes (APC) for @entity1 and @entity1 were 18.7 and 19.9, respectively. The most common morphological @entity5 were @entity981 , ALM, MM and @entity1072 which accounted for 60% of total @entity5 . Joinpoint analyze showed a significant decreasing trend for ALM in both sexes (P-value<0.05). CONCLUSIONS: @entity5 in Iran demonstrate an increasing trend for incidence rate and decreasing trend for @entity981 , ALM and @entity1072 morphology.
