Abstract:  Objective To analyze the temporal trend of malignant tumor incidence in Rugao city, Jiangsu province from 2013 to 2017, and to provide a scientific basis for cancer prevention and treatment. Methods The incidence time data of malignant tumors in Rugao city from 2013 to 2017 were collected. The crude incidence, Chinese standard population rate(ASR China), world standard rate (ASR, world) and annual change percentage (APC) of malignant tumors were calculated for different genders, different age groups and different categories. Results From 2013 to 2017, no significantly increasing or decreasing trend was observed in crude incidence, ASR China and ASR world of malignant tumors in Rugao (APC=0.63%, -1.75%, -1.87%, all P>0.05), and all the indices of male malignant tumors were significantly higher than those of female. The crude incidence of malignant tumor in the whole population and male residents of Rugao city showed an significantly decreasing trend (APC=-4.01%, -7.86%, all P<0.05) in age 15-44 group, but there was no significantly decreasing trend in other age groups. The crude incidence of female residents in all age groups showed no obvious trend. In the past 5 years, esophageal cancer ranked first in the incidence of malignant tumors in Rugao, followed by lung cancer, liver cancer, gastric cancer and colorectal cancer. Among the top 10 malignant tumors, the crude incidence of lung cancer showed a significantly increasing trend (APC=5.71%, P<0.05), and the ASR China of esophageal cancer and gastric cancer showed a decreasing trend (APC=-6.66%, -5.27%, all P<0.05). The crude incidence of lung cancer of male showed a significantly increasing trend (APC=7.48%, P<0.05), while the male ASR China of gastric cancer and the crude incidence of brain and central nervous system tumors showed a decreasing trend (APC=-6.80%, -1.88%, all P<0.05), No obvious trend was observed in the incidence of the top 10 malignancies of female. Conclusions From 2013 to 2017, the incidence of malignant tumors in Rugao city, Jiangsu province is relatively stable, but lung cancer show a rapidly increasing trend. In the future, more attention should be paid to lung cancer, and target-based prevention and control measures should be taken.
