[Analysis of mortality and years of life lost of malignant tumors among inhabitants in rural area of Feicheng city from 2000 to 2010].

OBJECTIVE

To analyze the mortality trends and disease burden of malignant tumors in rural area of Feicheng city from 2000 to 2010, and to provide basic information for the prevention and treatment of malignant tumors in this area.

METHODS

The data of cancer mortality from 2000 to 2010 from Feicheng Cancer Registry database were checked. Mortality rate, standardized mortality rate, potential years of life Iost (PYLL), standardized potential years of life lost (SPYLL), average years of life lost (AYLL) and other indexes were calculated and analyzed. The trend of the standardized rates transformed by the natural logarithm over time was assessed by Prais-Winsten regression method in which the errors was assumed to follow a first-order autoregressive process. STATA 12.0 was used to analyze the data.

RESULTS

In average, the crude mortality rate was 199.67 per 100 000 (264.69 per 100 000 in males and 137.24 per 100 000 in females), and the standardized mortality rate was 157.00 per 100 000 (200.49 per 100 000 in males and 101.31 per 100 000 in females). There were no significant changes in the trends of all standardized rates. For males, the mortality rates of lung and colorectal cancers increased significantly, and for females, the rates of lung and breast cancers had increased trend while the rate of esophageal cancer showed a downward trend. There were no statistically significant changes in other main malignant tumors. During 2000 to 2010, the PYLL of malignant tumors in Feicheng was 183 685.0 person-years, and PYLL rate was 23.3 per 1000. The SPYLL was 153 091.0 person-years, SPYLL rate was 19.4 per 1000, and AYLL was 14.8 years.

CONCLUSIONS

There are no obvious changes in the trends of standardized mortality rates in rural area of Feicheng over the past 11 years. For males, the mortality of lung cancer and colorectal cancer is increasing, and for females, the rates of lung and breast cancers have an increasing trend while the rate of esophageal cancer shows a decreasing trend. The prevention and control of digestive malignant tumors, lung cancer and breast cancer are getting seriously important and should be the focal point in this issue.
