Objective:To report the time trends of cancer incidence in urban Beijing from 1998 to 2007.Methods:All data were obtained from Beijing Cancer Registry from 1998-2007 in urban Beijing.Time trends of incidence rate of cancer were assessed by annual percentage change(APC)of age-standardized incidence rate(ASR)of world standard population during this 10-year period.Results:For all 156851 cancer cases combined,the incidence rate rose in both males and females,with an APC of 2.23% and 3.74%,respectively.The incidence rate of upper gastrointestinal cancers declined significantly,with an APC of-2.83% in esophageal cancer and-1.37% in male gastric cancer,while lower gastrointestinal cancer,such as colorectal cancer,increased with an APC of 4.080/x.The rates of kidney and bladder cancer increased with an APC of 7.93% and 5.57%,respectively.For women,the APC continued to rise in breast cancer(4.98%/x),ovary cancer(6.16%),cervix uteri cancer(11.74%),corpus uteri cancer(6.96%)and thyroid gland cancer(13.39%/x).The rate of prostate cancer among men increased with an APC of 8.58%;the rate of lymphoma and leukemia increased with APC of 5.48% and 5.44%,respectively.Conclusion:Because of population aging and urban modernization,the cancer burden in Beijing has become more and more severe and similar to the western developed countries
