Abstract:
Objective:To provide scientific basis for prevention and control measures of island regions through analyzing the characteristics of malignant tumor incidence and mortality in eastern island areas of China and comparing the data with the national cancer mortality data in the same period. Methods:Using the incidence and mortality data of malignant tumor in Daishan county,Zhoushan collected by the Daishan Center for Disease Control and Prevention(CDC)from 2014 to 2019,which was stratified by gender,the crude incidence rates(CIR)and crude mortality rates(CMR)were calculated,and the top 10 malignant tumors with the highest incidence or mortality rates were then ranked.The Segi's world standard population was used to calculate the age-standardized incidence(ASIR)and age-standardized mortality rate(ASMR).The local data were compared with the national cancer mortality data from 2014 to 2019,and Chi-square test was used to analyze the differences between these two sets of data using the SPSS software.The difference was considered statistically significant when P<0.05. Results:There was a total of 7 305 incidence cases of malignant tumors in Daishan county,Zhoushan from 2014 to 2019.The CIR was 662.39/105 and the ASIR was 306.81/105.Notably,the CIR was the highest in the age group of 75-79 years old.The top 5 malignant tumors with the highest incidence rates were lung cancer(27.15％),gastric cancer(12.76％),liver cancer(10.95％),colorectal cancer(6.92％)and breast cancer(5.42％),whose ASIR were 75.09/105,32.06/105,31.01/105,17.81/105 and 18.36/105,respectively.There was a total of 3 412 mortality cases of malignant tumors in Daishan county,Zhoushan from 2014 to 2019.The CMR was 309.39/105 and the ASMR was 122.73/105.Notably,the CMR was the highest in the age group of 80-85 years old.The top 5 malignant tumors with the highest mortality rates were lung cancer(24.94％),liver cancer(18.64％),gastric cancer(17.00％),colorectal cancer(7.56％)and esophageal cancer(5.72％),whose ASMR were 29.65/105,24.97/105,19.01/105,8.75/105 and 6.60/105,respectively.The total ASMR of malignant tumors in Daishan county,Zhoushan was higher than national total ASMR from 2014 to 2019(100.34/105)(P<0.001).Specifically,the ASMR of gastric cancer,lung cancer and colorectal cancer in Daishan county were significantly higher than national levels(gastric cancer:12.46/105;liver cancer:16.45/105;colorectal cancer:6.63/105)(P<0.01),whereas no significant difference in the ASMR of lung cancer and esophageal cancer between Daishan county and the whole nation(lung cancer:28.06/105;esophageal cancer:7.61/105)was observed. Conclusion:Lung cancer,gastric cancer,liver cancer and colorectal cancer were malignant tumors with higher incidence and mortality rates in Daishan county,Zhoushan from 2014 to 2019.Particularly,the ASMR of gastric cancer,liver cancer and colorectal cancer were significantly higher than the national levels,and these malignant tumors should be considered as the major focus of cancer prevention and control.
