Abstract:
Objective To describe characteristics of invasive cervical cancer (ICC) mortality and analyze its temporal trend.
Methods Based on the mortality data of ICC in Shanghai Death Registration System, annual percentage change (APC) was used to analyze the temporal trend of mortality from ICC from 1974 to 2011.
Results The ICC mortality was relatively low in Shanghai. In 2007-2011, the crude mortality of ICC was 2.48/100 000 and the standardized mortality was 1.26/100 000. The mortality of ICC in Shanghai urban areas was higher than that in the suburbs. Compared with the period of 1974-1978, the median age of ICC deaths between 2007 and 2011 decreased 7 years, and the mortality rate in the age group of 30-44 years was higher than its counterpart in 1974-1978. The standardized ICC mortality decreased 84.04% from 1974 to 2011. However, the results of temporal trend analysis demonstrated an increasing ICC standardized mortality from 1999. The ICC fatalities in the suburbs showed a decreasing trend before 1997 and a rising trend after 1997. A downward trend of ICC mortality before 1993 and then an upward one after 1993 were identified in the ICC fatalities of the age group of 35-44 years.
Conclusion Although the ICC mortality is low in Shanghai, there is an obviously increasing mortality in the younger age group. From 1999, the ICC mortality in Shanghai began to rise, which was mostly contributed by the age group of 55 years or older. Mass screening is needed in future examinations, especially for young women. The standardization of diagnosis and treatment should also be strengthened to reduce cervical cancer mortality.
